Staying in touch with the office Connecting at the office Why LapLink? LapLink gives you the freedom to leave the office without giving up access to your office computer and network resources. Whether you're traveling on business or working from home, you can still read your email, share the latest files with coworkers, access network programs and databases, browse the Internet over a high-speed connection, and collaborate with colleagues. Things you once could do only in the office you can now do remotely. Suppose you work at home Instead of joining the morning rush-hour traffic, you sit down at your home computer, connect to your office, and begin your workday as usual, by tackling your e-mail. While finishing your orange juice, you read your messages, write new ones, send replies--in other words, you operate much as you would in the office. You're using LapLink. In particular, you're using Remote Control, one of the LapLink services, to operate your office computer from home. On your home monitor you see what you would have seen had you commuted to work, and you operate your e-mail program as you would have from the office. You can even use your home printer for those messages you'll review later. Forget to get the latest copy of a file before leaving the office? Move to File Transfer, another LapLink service, and drag the file from the folder on the office network to its location on your hard drive at home. Since you're updating a file already on your home computer, the file is transferred almost before you know it. (In fact, LapLink merely updates the file, transferring only the parts that have changed.) Returning to Remote Control, you start a network application and access the company's huge product database. Just as you thought, customers ordered more blue widgets last month than during the previous two months combined! More grist for the quarterly report you're working on. 6 While you're still connected, you check out a rumor. Is the competition really selling their widgets at cutthroat prices? Connecting over the dedicated Internet line in the office, you visit the competition's Web site. Whew, no price war after all! A final check of your e-mail confirms your suspicions. It's off to Chicago tomorrow for a two-day business trip. Suppose you're on a business trip Settling into your hotel room, you take your eyes off the view long enough to discover a dedicated digital phone line. All the better to connect to your office computer, first by dialing the local number for your Internet service provider and then by opening a LapLink connection over the Internet. It's been a busy day. You need to catch up with your coworkers and exchange the latest files with them. You rush through your e-mail, finishing in time to connect to a coworker's computer. Her e-mail sounded desperate: if you're free before 7 o'clock this evening, could you help with the cover art for the annual report? Now you're looking at her monitor and talking to her at the same time, using another LapLink service, Voice Chat. After some discussion and trying this and that, the two of you agree: make the logo larger and reverse the colors. She'll have a finished draft waiting for you on the network in an hour. . . . Why LapLink? In an hour, however, you expect to be at your favorite Chicago restaurant, choosing from the dessert menu. On your way out the door, you schedule LapLink to reopen the connection with the office and synchronize folders on your laptop with folders on the office network. By the time you return to your hotel room, LapLink will have exchanged the quarterly report you finished on the red-eye flight this morning for the reports that await your review on the office network. And you'll get the latest draft of the cover art as well. Now to find the time to review all of this. 7 Staying in touch with the office lines, modems, and LapLink: these are the basics necessary to connect to the office from home or elsewhere. To these basics you can add a network, a network server, even the Internet. You determine how to connect by considering your office setup and what you want to accomplish when you are connected. Connecting to the office requires that your home computer or your laptop have a modem and a phone line to connect to. It must also be running LapLink. Depending on the availability of a network and the Internet in your office, you can then make any or all of these kinds of connections: · To your office computer directly · To your office computer or another office computer through the office network · To your office computer through the Internet If your computer is attached to a network, you can read your e-mail and access the customary network resources, though you cannot connect to other computers on the network. Phone Connecting to the office network If your office has a network, you can connect to the network and then to any computer running LapLink on the network, including your own. In fact, you can access any network resources normally available to you from the office. If you browse the Internet from your desk at work, for example, you can browse it from afar, too. To connect to the office network, simply dial in to a dedicated network dial-up server using Dial-up Networking. Connecting directly to your office computer If your office computer is equipped with a modem, you can connect to the computer directly, using Connect over Modem. Turn on the modem and leave LapLink running when you leave the office. Then connect through the modem and run programs and transfer files as you would normally. Connecting over the Internet Many workstations now have direct Internet access over dedicated, high-speed connections. If your office computer is one of these--and you have Internet access from your home computer or your laptop--you can connect to the office using Connect over Internet. 8 . . . Staying in touch with the office Using Connect over Internet is like connecting to your office computer by modem, with these advantages: · The office computer does not require a modem. · If you make a local call to connect to the Internet while you're away from the office, you can save money on your long-distance connections to the office. · If you connect to the Internet over a high-speed line while you're away from the office, you can improve the speed of your connection to the office. Before connecting over the Internet, set up your office computer for Internet access by publishing its address through the LapLink Internet directory. Then be sure to leave LapLink running. Connecting without running LapLink There may be times when you need to connect to your office computer running LapLink from another computer that doesn't have LapLink installed. You can transfer files between these two computers using Surf Up. Just like other Internet connections, you must first publish your office computer's Internet address. Then, to connect to the office computer, you go to www.laplink.com/surfup and enter the Internet address. Once you're connected you can view files and folders, download files to the local computer or upload files to your office computer. 9 Connecting at the office th greater resources at hand, you can make faster connections--and connect in more ways--while working in the office. Connect over a corporate network, for example, for the fastest file transfers. Use a LapLink cable to synchronize your desktop and laptop before and after you travel. And take advantage of your organization's direct connection to the Internet for cheap connections to distant locations. Wi Connect to other computers on your network If your office is equipped with a local network (LAN), you can connect directly to any other network computer running LapLink using Connect over Network. Because LapLink connections over networks are fast, they are ideal for sending large amounts of data in a short time. Suppose it's your job to distribute files to several computers every Tuesday. To automate the operation, create an Xchange Agent file by showing LapLink which files to copy and where to copy them. When Tuesday arrives, run the Xchange Agent yourself or schedule it to run unattended, at a time when the computers are usually idle. LapLink automatically connects to the computers, transfers files to the designated folders, and disconnects, all without assistance. It may also be your job to maintain those computers. Without leaving your desk, you can use Remote Control to troubleshoot problems on other computers, chatting with their users, if necessary. You could then locate the most recent files, whether on the laptop or the desktop, and copy them to the other computer. Instead, you create an Xchange Agent to perform the operation automatically. You also set up LapLink to run the agent whenever you start LapLink. In the future, simply attach the cable and run LapLink on both computers. Your files will be updated automatically. Connect to distant computers over the Internet Does your office have a direct line to the Internet? If so, go online and use Connect over Internet to locate other LapLink computers on the Internet and open connections. By combining LapLink and the Internet, you can connect to computers anywhere in the world. Before you use Connect over Internet, other LapLink users will set up LapLink on their computers so that their e-mail addresses, or other unique identifiers, are "published" through an Internet directory as their Internet addresses. They then notify you of their new addresses.1 Once you go online and run LapLink, merely supply a computer's Internet address to locate the computer and open a connection. Connect your laptop to your desktop If you take your laptop--and your work--with you when you leave the office, you know the routine: update files on your laptop before you leave; update files on your desktop when you return. To update files on either computer, attach a LapLink cable and run LapLink on both computers. A connection opens automatically. 10 1 Some computers have IP addresses that do not change. If you connect to one of these computers, use Dial-Up Networking and supply that computer's IP address. 12 14 16 18 20 22 24 26 28 30 32 34 36 38 2 Connecting to other computers How can I connect to other computers? Connecting directly by modem Dialing in to a network through a network server: Dial-Up Networking Using Address Book for modem connections Connecting over the Internet Making a computer available for Internet connections Making an Internet connection to a computer behind a firewall Connecting over an office network Using Address Book for network connections Connecting by cable Connecting by wireless Connecting over CAPI 2.0/ISDN Changing CAPI 2.0/ISDN performance in LapLink Connecting automatically How can I connect to other computers? Determine how to connect to another computer from the resources available to the two computers. For example, are both logged on to the same office network? Then connect over the network. Do both have Internet access? Then connect over the Internet. Use the tables in this section to help decide how to connect. No matter how you connect, you can always use File Transfer, Remote Control, and other LapLink services. LapLink provides several ways to connect to other computers. Which method you use depends on the resources available to the computers. Connecting over the Internet Can you connect to the Internet on the local computer? Yes No, but the office has a direct connection to the Internet Then connect to another LapLink computer over the Internet this way: Connect to the Internet as usual and then use Connect over Internet in LapLink. Use Connect over Dial-Up Networking to dial in to a network server and connect over the office Internet connection. For details see page 20 page 20 12 . . . How can I connect to other computers?

For a direct, LapLink to LapLink connection, dial a modem on another computer using Connect over Modem. For a connection to an office network--and then to any LapLink computer on the network--use Dial-Up Networking to dial a dedicated dial-up server (RAS). Usi Use Connect over Modem to dial a modem on another computer and open a LapLink connection to that computer. Entries you have created for modem connections in Address Book appear in the connection list to make connecting easier. When you dial directly to another LapLink computer, you have access to all the programs and files available to that 14 computer (including any network resources if the computer is logged on to a network). . . . Connecting directly by modem Connecting through a network Once on the network, you can connect to another LapLink computer and use LapLink services just as you would in a direct modem-to-modem connection. But there's more. When you dial in to a network, you can also: · Connect to any LapLink computer on the network, not just one. (You can even transfer files from one computer to another.) · Access all the network resources available to you in the office. If you normally browse the Internet over the network, for example, you can do the same thing from a remote location, using the browser on your local computer. · Enhance security by combining LapLink password protection with network security. For a Dial-Up Networking connection, your office network (either TCP/IP or IPX) must have a dial-up server. (If in doubt about your network, ask the network administrator.) Using Dial-Up Networking, you dial in to the network through this server. · The LapLink security setup of the computer you are connecting to must be changed to allow incoming connections. See page 42. · LapLink must be running on both computers. · Modem ports must be enabled in LapLink on both computers. When you use Connect over Modem, you see the Address Book entries you created for modem connections. When you use an entry to dial a connection, information stored in the entry is passed on to the remote computer for you. For details about using Address Book for modem connections, see page 18. To connect to another computer by modem: 1 Click the Connect button on the LinkBar, and then click Modem. 2 In the Connections list, click the connection you want to open. The connections listed under Manual Dial are your Address Book entries for modem connections. To create a new entry, click Address Book. 3 In the Dialing Location list, click the location you're dialing from. 4 Under Services, check services you want to use. 5 Click the Dial button. Dialing manually To dial a connection that is not complicated by such considerations as calling cards, outside lines, and country codes, you can type the phone number without creating an Address Book entry beforehand. LapLink dials the number exactly as you type it, regardless of how you have set up Dialing Properties. To dial manually: 1 Click the Connect button on the LinkBar, and then click Modem. 2 Click Manual Dial. 3 In the Phone Number box, type the number to dial. 4 Click the Dial button. 15 Dialing from an Address Book entry Before dialing a computer, it's a good idea to create an Address Book entry for that connection. Use the entry to store the phone number, requests for services (such as File Transfer and Remote Control), password, and other pertinent information. Dialing in to a network through a network server: Dial-Up Networking Dial-Up Networking to dial in to a dial-up server (RAS) and log on to a network from outside the office. Then connect to other LapLink computers on the network and use network resources as if you were still in the office. Use Use Dial-Up Networking to dial in to a dial-up server and connect to a network. Then open connections to other LapLink computers on the network. Use Dial-Up Networking to access a network after you leave the office. By dialing in to a dial-up server (RAS) on the network, you can connect to any computer running LapLink on that network. You can also connect to LapLink computers on the Internet and browse the Internet using the Internet connection in the office. In short, you can access the same network resources you use in the office. 16 Before you use Dial-Up Networking · Dial-Up Networking, a Windows feature, must be installed on the computer you dial from. See Windows help for instructions. · Your network must have a dedicated dial-up server (such as Novell NetWare Connect, Windows Remote Access Server, or Shiva NetModem). The computer you connect to must be connected to an IPX or TCP/IP . . . Dialing in to a network through a network server: Dial-Up Networking network.

In your entries you store phone numbers, requests for services (such as File Transfer and Remote Control), and passwords. When you use Connect over Modem, this information is passed on to the remote computer for you. You can also set up entries for connections you make to network computers after you dial in to a network using Dial-Up Networking. Maki For modem connections you make again and again, simplify the connecting process by adding entries to Address Book. Then access the information you store in these entries when you use Connect over Modem or DialUp Networking. Address Book is a convenient way of storing all the information you need to connect to another computer using Connect over Modem. Address Book works in tandem with Dialing Properties, the Windows feature that lets you determine how your numbers are dialed. Use Dialing Properties to charge a call to a calling card, for example, reach an outside line, or place longdistance and international calls. For more information about Dialing Properties, see Windows help. 18 To create an Address Book entry for a Connect over Modem connection: 1 Click the Address Book button on the LinkBar, and then click the Add button. 2 In the Description box, type a brief description of the remote computer for your own reference. 3 In the Computer Name box, type the LapLink name assigned to the remote computer. . . .

TIP If you want to have a phone number dialed exactly as you type it in the Telephone Number box, clear this box: Use Country Code and Area Code. TIP Requests for services in Address Book are honored only if the security setup of the remote computer permits. 6 Under Services, check the services you want to use. TIP You can change your selections later, as part of the connection process. You can also request new services after you connect. 7 Under Host Locking on Connect, check the kind of locking you want to take effect on the remote computer when you connect for Remote Control. You can lock a host (blank its screen or disable its mouse or keyboard) only if it has been configured to allow locking. 8 Under Security Information to Send, type the log-in name and the password you must provide in order to gain access to the remote computer. Reenter the password to confirm. When you finish the entry, you see Address Book and the description of the new entry. If you want to create another entry, click Add again and complete the entry. Otherwise, click Close. Using Address Book for dial-up connections to network computers For LapLink connections you make after dialing in to a network, set up Address Book entries to store requests for services and security information. This information is passed to the network computer after you connect to a network using Dial-Up Networking. As the Connection Type, use Network: Available Now if the computer normally appears in the list of available computers when you use Connect over Network in the office. Otherwise, use Network: TCP/IP Address and type the computer's IP address. To determine a computer's IP address, see page 27. Entering passwords LapLink Gold passwords are case-sensitive (i and I, for example, are treated differently). For connections to other computers running LapLink Gold, type passwords in capital or lowercase letters exactly as they were typed on those computers. NOTE Passwords in LapLink Pro, LapLink Tech, or LapLink 7.5 or earlier are not case-sensitive. In Address Book entries for connections to any of these versions, type passwords in ALL CAPITAL LETTERS. If you have old Address Book entries for such connections, retype their passwords in all capital letters. NOTE Because of the change in case sensitivity, Address Book entries created in an earlier LapLink version may no longer let you connect to computers that have also been upgraded. Have new passwords set up on those computers; then change your Address Book entries to match. 19 Connecting over the Internet to the Internet, and you can open connections to other LapLink computers anywhere in the world, without spending a fortune. To make a computer easy to find on the Internet, use the LapLink Internet directory to "publish" the computer's Internet address. Other computers can then supply this address to open connections using Connect over Internet. Connect Go online and use Connect over Internet to locate and open connections to LapLink computers anywhere on the Internet. Make a connection by supplying the address published by a remote computer through the LapLink Internet directory. When connected to another LapLink computer on the Internet, you can use Remote Control, File Transfer, and any of the other LapLink services you would use when connected directly by modem--often at reduced cost. For the easiest 20 Internet connections, use Connect over Internet and supply the Internet address the remote computer has published through an Internet directory like the one hosted by LapLink. . . . Connecting over the Internet Before you use Connect over Internet · Both computers must be connected to the Internet.1 · The remote computer (the one you are connecting to) must have its Internet address published through an Internet directory. See page 22. · The security setup of the remote computer must have been configured to allow incoming connections. See page 42. · The TCP/IP ports must be enabled in LapLink on both computers. See page 135. · LapLink must be running on both computers.2 Otherwise, click Manual Connect. In the Internet Address box type the remote computer's Internet address (the one the remote computer has published through an Internet directory). 4 Under Services, check the services you want to use. 5 Click OK. Using Address Book for Internet connections For LapLink connections you make using Connect over Internet, you can set up Address Book entries to store Internet addresses, requests for services, and security information. All of this is passed on to the network computer when you use Connect over Internet. When you create an Address Book entry for the Internet, be sure to specify Internet in the Connection Type box. Using Connect over Internet To connect to another LapLink computer on the Internet: 1 Connect to the Internet as usual. 2 Click the Connect button on the LinkBar, and then click Internet. 3 If you have created an Address Book entry for the connection you want to open, click the connection in the Connections list. 1 If you are out of the office and without access to the Internet, dial back to the office network and use the office Internet connection. See page 26. 2 If you are out of the office and without access to a computer with LapLink software, you can use LapLink Surf Up to connect. See page 50. Opening Internet connections using Connect over Network Just as you use Connect over Network for connections on a local TCP/IP network, so you can use it for connections on the Internet, a global web of TCP/IP networks. When you use Connect over Network, you must supply the computer's IP address, not an address published through an Internet directory. Connect over Network is most useful when you connect to computers whose IP addresses never change. For more information about using Connect over Network, see page 26. 21 Making a computer available for Internet connections Internet connections, like e-mail messages, need addresses. To make your computer available to other LapLink computers on the Internet, publish its address through an Internet directory. LapLink users who know this address can then locate your computer on the Internet and open connections from anywhere in the world. As a free service to our users, LapLink maintains the LapLink Internet directory server to promote Internet connections between computers running LapLink. To allow other LapLink computers to connect to a computer on the Internet, set up LapLink to have the computer's address published through the LapLink Internet directory. In Internet Directory Options, specify an e-mail address or some other unique identifier as the Internet address. Then notify other LapLink users so that they can connect by supplying the Internet address you have specified. Connecting to computers on the Internet is easy--when you know their IP addresses. But IP addresses can be hard to determine, and they often change. If you dial in to an Internet service provider, for example, your computer may be assigned a different IP address each time you go online. So how do you make your computer available to other LapLink computers on the Internet? You have your e-mail address (or other unique identifier) "published" as your Internet address. You then let other LapLink users connect to your computer by telling them your Internet address. NOTE If the computer is behind a firewall, there are additional requirements. See page 24. 22 . . . Making a computer available for Internet connections Use LapLink to specify the address to be published and when it will be published--for example, whenever you are using LapLink on the Internet. Use the LapLink Internet directory to publish your address; the directory is available without cost to LapLink users, and you don't have to sign up to use it. NOTE Publishing your Internet address does not open your computer to unwanted connections. LapLink users who know your published address can connect; others cannot, even if they are using NetMeeting or other programs that rely on Internet directories. To set up LapLink to have your computer's address published on the Internet: 1 On the Options menu, click Internet Directory Options. 2 In the Internet Address box, type your e-mail address or another unique identifier. This will be your Internet address. Give it (as well as login name and password) to any LapLink user you allow to connect to your computer on the Internet. 3 Set options to determine how to publish your Internet address: · To publish the address yourself, without a confirmation dialog box, clear this box: When Manually Publishing My Address, Show Confirmation. · To have LapLink publish your address for you, check this box: Automatically Publish My Address When I'm Connected. 4 Set the Internet directory to publish your computer's address like this: Use a LapLink Directory Server: ils.laplink.com 5 Click OK. TIP In addition to publishing a computer's Internet address, you must also change its security setup before other computers can connect over the Internet. For more information, see page 42. Publishing your Internet address You can set up LapLink to publish your address automatically whenever you run LapLink on the Internet (step 3, above). Or you can publish it yourself. To publish your Internet address yourself: 1 Connect to the Internet as usual. 2 On the Connect menu, click Publish My Internet Address. 23 Making an Internet connection to a computer behind a firewall If one of the computers you want to connect to is behind a firewall, you can use LapLink's Firewall Connection Service to make the connection. For example, if you want to connect to your work computer from home and your work computer is behind a corporate firewall. When the computer outside the firewall requests a connection, the computer inside the firewall uses the Address Book entry to initiate the connection. The Log-in name and password in the Log-in List entry must match the log-in name and password in the Address Book entry. 24 . . . Making an Internet connection to a computer behind a firewall You must configure both computers before you can make a firewall connection. First, configure the computer inside the firewall to accept incoming connections using either a Login List or configuring a Public System (Log-in List is more secure) and then create an Address Book entry. You must also create a Log-in list entry on the computer outside the firewall. This entry must match the Address Book entry you created on the computer inside the firewall. NOTE If you are sharing your computer with someone other than yourself, you will need to coordinate the firewall configuration with that other person. · The TCP/IP ports must be enabled in LapLink on both computers. See page 135. · LapLink must be running on both computers. NOTE For additional security, LapLink allows users to change the port number that they want to connect through.

In each entry you store the kind of network connection, the kinds of services (such as File Transfer and Remote Control) to be opened automatically, and the password. When you use Connect over Network, this information is passed on to the remote computer for you. For network connections you make again and again, simplify the connecting process by adding entries to Address Book. Then access the information you store in these entries when you use Connect over Network. When you connect over a local network, you may be able to choose from a list of computers currently available on the network. If not, you type the computer's network (TCP/IP) address. When you create an Address Book entry for a network connection, you designate which of the two types of connections you are using: · Network: Available Now For connections that appear in the list of currently available connections. · Network: TCP/IP Address For connections that require a TCP/IP address. 28 . . . Using Address Book for network connections To create an entry in Address Book for a network connection: 1 Click the Address Book button on the LinkBar and then click the Add button. 2 In the Description box, type a brief description of the remote computer for reference. 3 In the Computer Name box, type the exact LapLink name assigned to the remote computer. 4 In the Connection Type list, click Network Available Now or Network TCP/IP Address. 5 If you selected Network TCP/IP Address, type the IP address of the remote computer under TCP/IP Address. For help in determining a computer's IP address, see page 27. 6 Under Services, check the services you want to open when you connect to the remote computer, such as File Transfer and Remote Control. Your requests for services in Address Book will be honored only if the security setup of the remote computer permits. 7 Under Host Locking on Connect, check the kind of locking, if any, you want to take effect on the remote computer when you connect for Remote Control. You can lock a host (that is, blank its screen or disable its mouse or keyboard) only if it has been set up to allow locking. 8 Under Security Information to Send, type the log-in name and the password you must provide in order to gain access to the remote computer. Reenter the password to confirm. When you have finished the entry, you see Address Book and the description of the new entry. If you want to create another entry, click Add again and complete the entry. Otherwise, click Close. TIP To edit an entry in Address Book, click the entry, and then click Edit. To copy an entry for revision as a new entry, click Copy. To delete an entry, click Delete. Entering passwords LapLink Gold passwords are case-sensitive (i and I, for example, are treated differently). In Address Book entries for connections to other computers running LapLink Gold, type passwords exactly as they were typed on those computers, using capital letters and lowercase letters as necessary. NOTE Passwords in LapLink Pro, LapLink Tech, or LapLink 7.5 or earlier are not case-sensitive. For connections to computers running any of these earlier versions, type passwords in ALL CAPITAL LETTERS. If you have old Address Book entries for such connections, retype their passwords in all capital letters. NOTE Because of the change in case sensitivity, Address Book entries created in an earlier LapLink version may no longer let you connect to computers that have also upgraded. Have new passwords set up on those computers; then change your Address Book entries to match versions. 29 Connecting by cable you connect two computers by LapLink cable, attach the cable--serial, parallel, or USB Network--to both computers and start LapLink on both computers.

In LapLink, click Port Setup (Options menu) and enable the same redirected port for wireless communications. 33 Connecting over CAPI 2.0/ISDN If CAPI 2.0/ISDN lines are available to your computer and the computer you are connecting to--and both computers are set up for CAPI 2.0/ISDN communications--you can open a high-speed connection and use Remote Control, File Transfer, and other LapLink services. To connect, click the Connect button on the LinkBar, and then click CAPI 2.0/ISDN. Use Connect over CAPI 2.0/ ISDN to link computers wherever the CAPI 2.0 version of ISDN is available. Entries you have created for CAPI 2.0/ISDN connections in Address Book appear in the connection list to make connecting easier. CAPI 2.0/ISDN is an implementation of ISDN, an international communications standard for sending voice, video, and data over digital telephone lines, at faster rates than those possible using modems. NOTE LapLink does not offer CAPI 2.0/ISDN as a means of connecting unless CAPI 2.0/ISDN is installed on your computer. CAPI 2.0/ISDN is widely used in Europe, particularly in Germany. In North America ISDN seldom is implemented as CAPI 2.0, but you can still use your ISDN device for highspeed LapLink connections. If you use your ISDN device as a modem, use Connect over Modem in LapLink. If you use it to dial in to, and log on to, a network, use Connect over Network in LapLink. 34 . . . Connecting over CAPI 2.0/ISDN Before using Connect over CAPI 2.0/ISDN · A CAPI 2.0/ISDN adapter and driver must be installed on both computers. · Both computers must be running a version of LapLink that supports CAPI 2.0/ISDN. · The security setup of the remote computer (the one you are connecting to) must be configured to allow incoming connections. See page 42. · CAPI 2.0/ISDN ports must be enabled in LapLink on both computers. · LapLink must be running on both computers. Dialing from an Address Book entry Before dialing a computer, it's a good idea to create an entry for that connection in Address Book. Though you do not dial directly from Address Book, you can choose among its entries when you connect to a remote computer. To create an entry in Address Book for a CAPI 2.0/ISDN connection: 1 Click the Address Book button on the LinkBar and click the Add button. 2 In the Description box, type a brief description of the remote computer as a reference. 3 In the Computer Name box, type the exact name assigned to the remote computer in LapLink. 4 In the Connection Type list, click CAPI 2.0/ISDN. 5 Under Phone Number, type the phone number. 6 Under Services, check the services you want to use when you connect to the remote computer (such as File Transfer and Remote Control). TIP Requests for services in Address Book will be honored only if the security setup of the remote computer permits. 7 Under Security Information to Send, type the log-in name and the password you must provide in order to gain access to the remote computer. Reenter the password to confirm. For connections to other computers running LapLink Gold, type passwords exactly as they were typed on the other computers; that is, use capital letters and lowercase letters as necessary. TIP For passwords to computers running earlier versions of LapLink, type passwords in ALL CAPITAL LETTERS. If you have old Address Book entries for such connections, retype their passwords in all capital letters. 35 Connecting to a computer over CAPI 2.0/ISDN To connect to a computer over CAPI 2.0/ISDN: 1 Click the Connect button on the LinkBar, and then click CAPI 2.0/ISDN. 2 Click the name of the computer you want to connect to in the Connection list or type a phone number under Dialing. The connections listed under Manual Dial are your Address Book entries for CAPI connections. To create a new entry, click Address Book. 3 Under Services, check the services you want, such as File Transfer and Remote Control. You can choose any combination of these services. 4 Click the Dial button. Changing CAPI 2.0/ISDN performance in LapLink ore using CAPI 2.0/ISDN in LapLink, you may want to customize the way that LapLink responds to CAPI 2.0/ISDN calls and uses the two channels available for LapLink communications. For example, you can specify that LapLink not respond to any incoming calls to a particular channel, or you can double the rate at which data is transmitted over your CAPI 2.0/ISDN connections. In Port Setup, you can modify the way LapLink implements CAPI 2.0/ ISDN connections. Bef 36 . . . Changing CAPI 2.0/ISDN performance in LapLink To change CAPI 2.0/ISDN performance in LapLink: 1 On the Options menu, click Port Setup. 2 Under Port Settings, click CAPI. 3 Click the Configure button. 4 If you do not want LapLink to answer any incoming CAPI 2.0/ISDN calls, clear the Enable box under Auto Answer. To answer calls to only one number, type the number in this box: Accept Calls Only on the Following Numbers. 5 If you want to combine the two CAPI 2.0/ISDN channels for faster connections, check the Enable box under Channel Bonding. Be sure that channel bonding is also enabled on the computer you will connect to. 6 Customize the Timeout options as necessary. The Callback Timeout, Callback Delay, and Redial Delay settings are specified in seconds. 7 Click OK. TIP If you don't want LapLink to answer any incoming calls, clear the Enable box under Auto Answer; then make sure that the Accept Calls Only on the Following Numbers box is blank. TIP When typing the number to accept calls to, use only numerals; avoid characters like dashes, parentheses, slants, and periods. When typing more than one number, use a semicolon to separate them. Channel bonding CAPI 2.0/ISDN provides two channels that can be used for LapLink communications. Each channel has a transmission speed of 64 Kbps. By combining ("bonding") these channels, the transmission rate can double to 128 Kbps. At the outset, LapLink does not use channel bonding, even when both channels are available. This setting keeps transmission costs to a minimum for users who pay additional fees for each channel connection. For faster transmissions, enable channel bonding. When both channels are available, LapLink can then transmit at speeds up to 128 Kbps. TIP Be sure to enable channel bonding on both computers. LapLink may not be able to make a connection between them otherwise. TIP When one channel is already in use, LapLink uses the available channel to transmit at 64 Kbps, even when channel bonding is enabled. Answering calls At the outset, LapLink is set up to answer all incoming CAPI 2.0/ISDN calls on both channels. You can modify this so that it does not answer any of these calls or it answers calls to just one of the channels. 37 Connecting automatically Once you have established a connection, you can save it for easy restoration later. You can restore a saved connection by double-clicking a shortcut icon, setting up LapLink to restore the connection automatically when you start LapLink, or restoring the connection while running LapLink. When LapLink restores a connection, it connects to the same computer or computers and opens the same services. You can restore a saved connection three ways: · Double-click its desktop icon. · Set up LapLink to restore the connection automatically, whenever you run LapLink. · Restore the connection yourself, while using LapLink. Instead of spending time connecting to the same computer and opening the same services time after time, you can save the connection and use the saved connection as a convenient way to reconnect later. NOTE To connect to several computers at once, open connections to those computers before saving connections. 38 When you save a connection, you record such details as the number and types of connections (modem, network, Internet, cable), the names of computers, and the kinds of services in use. Each connection is saved as a file. Opening the file reopens the connections and services and arranges windows to appear much as they did before. . . . Connecting automatically Saving a connection To save a connection: 1 Open one or more connections as usual. 2 On the Connect menu, click Save Connections. 3 In the File Name box, type a name to identify the connection file. 4 Click Save. 5 When asked whether you want a shortcut icon for this connection on your Windows desktop, click Yes or No. 2 On the Startup tab, check this box: Restore Saved Connections at Startup. 3 Click the name of the connection file you want to open, or type it in the Connection File box. If the file does not appear in the list of files, click the Browse button and locate the drive and folder containing the file. TIP Connection files have the .LLC extension. In Windows 95 and Windows 98, they are stored in the My Documents folder. In Windows NT, they are stored in the \Profiles\yourname\Personal folder within the Windows folder (where yourname is your Windows NT logon name). 4 If you want the connection restored without confirmation, click Automatically Connect at Startup. Otherwise, click Ask Before Connecting. 5 Click OK. To open a saved connection while running LapLink: 1 On the Connect menu, click Restore Connections. 2 Click the name of the connection file you want to open, or type it in the File Name box.

To allow incoming connections, change the security setup to Protected System and create one or more entries in the Log-in List. In each entry, specify the password and the log-in name the user must provide to open an incoming connection, and grant the user permission to use services and other features. Click Log-in List Only (Protected System) and then click the Log-in List button. Create an entry in your Log-in List for the remote user. The safest way to allow incoming connections is to set up password-protection by creating entries in the Log-in List. If you will be the only person to connect to this computer, make a single Log-in List entry and grant yourself whatever privileges you want. For other users, create separate entries for each user or group of users according to privileges granted. 42 . . . Allowing incoming connections To set up password-protected access to your computer: 1 Click the Security button on the LinkBar. 2 On the General tab, click Log-in List Only (Protected System). 3 Click the Log-in List button, and then click the Add button. 4 On the General tab, type the log-in name and the password the user must provide to make a connection to your computer. Reenter the password and click OK to confirm. 5 Under Services, check File Transfer, Remote Control, or any of the other services you want to make available to the user. 6 Under Locking Permissions, check options to determine whether the user can blank the screen of your computer and disable its mouse and keyboard. TIP You can grant locking permissions only if you select Remote Control as an available service. 7 To deny access to particular drives and folders, click the Folder Security tab. For more information see page 44. 8 To specify whether or how a user opening a connection by modem is to be called back, click the Modem Callback tab. For more information, see page 48. case letters. The introduction of case sensitivity has these important consequences: CAUTION For incoming connections from computers running versions earlier than LapLink 2000,1 type passwords using ALL CAPITALS. If your Log-in List has passwords for such connections, retype them as all capitals, or assign new passwords. CAUTION If your Log-in List contains passwords assigned in an earlier LapLink version, other computers that have also upgraded may not be able to connect to your computer until you assign new passwords. Setting up a public system If security is not an concern, you can open your computer to any LapLink users. Though you do not require that they type a password, you can limit the services, drives, and folders they can access. To allow access to your computer without password protection: 1 Click the Security button on the LinkBar. 2 On the General tab, click Anybody (Public System). Then click the Public Privileges button. 3 On the General tab, check the services and locking privileges you want to grant. 4 On the Folder Security tab, deny access to drives and folders as you wish. For more information see page 44. 1 Versions before LapLink 2000 include LapLink Pro, LapLink Tech, and LapLink 7.5 or earlier. Specifying passwords LapLink Gold passwords are case-sensitive (i and I, for example, are treated differently). For incoming connections from computers running LapLink Gold, you can specify more secure passwords by mixing capital letters and lower- 43 Denying access to certain drives and folders you open your computer to incoming connections, you specify whether all drives and folders-- or only certain ones--are accessible to users who connect to your computer for File Transfer. You can deny access to an entire drive or to any parts of one, and you can grant different privileges to different users. Folders removed from access in a Log-in List entry... ...do not appear in File Transfer windows on a remote computer. When Opening your computer to incoming connections does not mean that files on all your drives and folders must be accessible to other users. You can "hide" certain drives and fold44 ers so that other users will not see them in their File Transfer windows and cannot copy files to or from them. . . . Denying access to certain drives and folders CAUTION Denying access to a drive or folder makes it invisible to anyone who connects for File Transfer but has no effect in Remote Control. Anyone who connects for Remote Control can still access all of your files. You can set up drive and folder security when you secure your computer using the Log-in List. Specify a different setup for each entry in the list if you like. Until you specify otherwise, every user in your Log-in List has access to all of your drives and folders. To limit access to certain drives and folders: 1 Click the Security button on the LinkBar. 2 Ensure that Log-in List (Protected System) is selected, and click the Log-in List button. 3 Click the Add button to create an entry in the Log-in List. TIP If you want to change an existing entry, highlight it in the list of current users and click the Edit button. 4 Click the Folder Security tab and then click Only Allow Access as Specified Below. Access is now denied to all drives and folders. TIP You can navigate through the drives and folders on the Folder Security tab much as you do in a File Transfer window. For fastest navigation, double-click a drive or folder or click the plus sign beside it. 5 In the list of drives and folders, highlight each one you want to make accessible and click the Allow button. TIP You can also specify drive and folder security for a computer designated as a public system (no password required). Click the Security button on the LinkBar and click the Public Privileges button. Then click the Folder Security tab. 45 Locking out password crackers you open your computer to incoming connections, it's a good idea to include Lockout protection so that anyone who supplies an incorrect password more than a particular number of times is denied access to your computer. You enable Lockout and set the number of allowable tries as part of Security setup. When Use Lockout to protect against someone who attempts to guess your passwords. As set up here, Lockout will take effect after five failed attempts for any login name. Someone supplying the log-in name NormaJean has been locked out and won't be able to connect even if he or she supplies the correct password. Like combination safes, security passwords can be cracked. Password crackers use a variety of techniques; some techniques are more sophisticated than others, but almost all require guessing. To guard against unauthorized access, use Lockout to bar anyone who makes repeated attempts at guessing a password for entry to your computer. Suppose you are setting up your office computer for access from home. In the Log-in List of LapLink security, you assign yourself both a log-in name and a password. 46 . . . Locking out password crackers Though you are careful to specify as secure a password as possible, you still want to have Lockout as additional protection. So you instruct LapLink to refuse entry after a certain number of incorrect passwords. To lock out anyone who repeatedly tries to connect using incorrect passwords: 1 Click the Security button on the LinkBar. 2 On the Lockout tab, check this box: Lock Out User after Repeated Wrong Passwords. 3 In the Lock Out After This Many Wrong Passwords box, click the number you want to allow before Lockout takes effect. TIP The lower the number, the less the security risk. 4 Click OK. You can reset to zero the count for any or all of the log-in names. This action also makes a locked out name usable once again. TIP Unless a log-in name has been labeled Locked Out, its count is reset to zero automatically whenever a user connects using that log-in name and the correct password. To reset to zero the count for a single log-in name: · Click the log-in name and click the Reset User button. To reset to zero the count for all log-in names: · Click the Reset All button. Tips for more secure passwords · Use at least six characters. · Include letters (both lowercase1 and capitals), numbers, punctuation, and symbols. · Avoid any words found in dictionaries. (Some password-cracking programs rely on dictionaries to guess passwords.) · Don't make your passwords so complex or long that you can't remember them. · Change your passwords every 45 days. 1 Passwords for incoming connections from versions earlier than LapLink 2000 are the exception. They must be all capital letters. Monitoring failed log-in attempts Lockout is designed to monitor and control access according to the log-in names in your Log-in List. A separate count of failed attempts is kept for each log-in name; when a count reaches your maximum (step 3 above), users can no longer connect using that log-in name. Beside the log-in names listed on the Lockout tab appear numbers for the number of incorrect passwords. When a count reaches the maximum, the log-in name is labeled Locked Out. 47 Allowing or requiring callbacks you allow incoming modem connections, you can require that the remote computer be called back before a connection is opened. Or you can let the remote computer determine whether to be called back. In both cases you can supply the phone number ahead of time or leave the number to the other computer. You set callback options in the Log-in List. Hello. I'll call you back if you give me your current phone number. Otherwise, I'll connect you without reversing the call. When Hello. I'll call you back if you give me your current phone number. Otherwise, I'll have to disconnect. Hello. Do you want me to call you back at 555-1111? Otherwise, I'll connect you without reversing the call. Hello. Do you want me to call you back at 555-2222? Otherwise, I'll have to disconnect. A callback occurs when a remote computer attempts to connect to your computer by modem; instead of completing the connection, LapLink reverses the call by hanging up 48 and then dialing the remote computer. The connection to your computer is completed when the remote computer answers. . . . Allowing or requiring callbacks You can use callbacks as a security measure: require a callback to a phone number you specify. Or you can use callbacks to save money, as when you are connecting to your office from a hotel room. You can set callback options when you secure your computer using the Log-in List. Specify a different option for each entry in the list if you like. To set callback options: 1 Click the Security button on the LinkBar. 2 Ensure that Log-in List (Protected System) is selected and click the Log-in List button. 3 Click the Add button to create an entry in the Log-in List. TIP If you want to change an existing entry, highlight it in the list of current users and click the Edit button. 4 Click the Modem Callback tab. 5 Click one of these options: · None Prevents callbacks. · Optional, Any Number Lets the remote user decide whether to be called back; users who choose to be called back can specify the number to dial. This is the most flexible of all the options. · Optional, Specified Number Only Lets the remote user decide whether to be called back to the number you specify or to open the connection without any callback. Only the number you specify in the Phone Number box can be dialed for the callback. · Required, Any Number Requires remote users to be called back but allows them to specify the number to be dialed. The number can vary from session to session. · Required, Specified Number Only Requires the remote user to be called back to the number you specify in the Phone Number box. 6 If you clicked either of the options for which you must specify a phone number, type that number in the Phone Number box. Type the entire number, including any prefixes or suffixes necessary to dial the remote computer from this one. (Your Dialing Properties settings do not apply here.) TIP Do not require callbacks from computers that connect by running Xchange Agents. The agents will not finish because they cannot perform callbacks. 49 Allowing incoming connections from computers without LapLink th LapLink's new Surf Up feature, you can set your security to allow incoming connections from computers that do not have LapLink installed. For example, if you're traveling and need to access files on your home computer. To allow incoming Surf Up connections on your computer, change the security setup to either a Protected System or a Public System. For a Protected System, define a log-in name and password. Click Log-in List only (Protected System) and then click the Log-in List button. Select Surf Up as a service. Wi Enabling Surf Up connections to your LapLink computer The safest way to allow incoming Surf Up connections is to set up password-protection by creating entries in the Log-in List. 50 If security is not an concern, you can open your computer to any user. LapLink doesn't require the user to type a password for a Public System but you can limit the drives and folders they can access.
