LapLink Technical provides the services for communicating with one computer or several computers at the same time. Whether youre using a modem, network, wireless device, or cable, you can connect to other computers that are also running LapLink. Once you are connected, you can transfer files between the computers. When youre at home or on the road, you can use files and programs on your office computeras well as other computers on your office network. You can even chat (through Text Chat or Voice Chat) with someone sitting at your office computer while you transfer or work on office files from a remote location. Go to illustration¾ Connect as you want Using a modem, network, wireless device, or cable, you can connect to other computers using the same device. In one session, you can connect to several computers, using a variety of these devices, limited mainly by the number of devices and resources on your computer. You can also take advantage of the Dial-Up Networking feature of Windows to connect by modem to other network computers running LapLink. Using this modem-to-network connection provides full access to the network; its like being connected to the network directly. Different situations call for specific devices. Cables and wireless devices work well when connecting your laptop to your desktop computer from a short distance. Networks make it easier to connect to many different computers in your local company network, a wide-area network, or the Internet. Modems work well at any time when you can use a phone line to connectwhether youre at home or on the road or communicating with someone in another company. Use the services you want LapLink servicesFile Transfer, Remote Control, Print Redirection, Text Chat, and Voice Chatoffer five ways to communicate with other computers, no matter what device youre using. You can select one or more services as you connect and add other services as you need them. In the same session, you can use different services simultaneously or at different times, on one or more computers. s With File Transfer, you can move or copy files between computers. Customizing any of the several File Transfer settings simplifies complicated transfers. And using Xchange Agent automates the repetitive process of keeping two computers in sync. Traveling Softwares patented SpeedSync technology makes updating files faster by comparing files so that only changesnot entire files are transferred. A comprehensive security system, including encryption, protects your valuable data at all times. Introducing LapLink Technical 9 s With Remote Control, you control another computer as though you were sitting at that computer, using its keyboard, mouse, and programs while looking at its screen. Whether your computer is controlling or being controlled, you have the same setup and startup procedures. With Print Redirection, you can work on a document at one end of a LapLink connection and print it at the other end. For example, you can prepare a document at home, make a LapLink connection to your office computer, then print the document on an office printer. ½ Go to topic summary s You can set up Print Redirection any time after setup by starting LapLink and clicking Print Redirection from the Options menu. s With Text Chat, you talk with someone at another computer by exchanging messages. When you have only one phone line, you can use your modem to connect to the remote computer for File Transfer or Remote Control, and then use Text Chat to talk to the person at the other end. With Voice Chat, you can speak with another user over the line you are using to transmit data. You speak into a microphone attached to your computer and listen through a headset or speakers. s 10 Chapter 1 What you can do in LapLink Technical LapLink Technical gives you five services for working with other computers: File Transfer, Remote Control, Print Redirection, Text Chat, and Voice Chat. Features like Xchange Agent and Address Book save time and simplify your work. Go to illustration¾ Choosing the right service for the job you need to do is simple when youre using LapLink. You have five services to choose from: File Transfer, Remote Control, Print Redirection, Text Chat, and Voice Chat. Being familiar with their distinctions makes choosing the right service easier. LapLink is versatile, designed specifically so you can use services when you want, as you want. Use one service at a time or all services at once. Use one service when connecting to the first remote computer; use a different service when connecting to another computer. Working on a remote computer? s You can copy information on one computer and paste it on another computer. Using the Remote Control service, you can operate a remote computer using your computers keyboard and mouse. You can use the remote computers applications and network connections. Since all the work you do is actually performed on the remote computer, Remote Control is especially helpful to laptop owners who cant use their office computers programs on their laptop. Remote Control is also helpful when youre telecommuting or troubleshooting a remote computer. Transferring files between computers? s To protect the confidentiality of files you send over the Internet, you can have LapLink encrypt them beforehand. Whether youre hundreds of miles away or in the same room, use the File Transfer service to exchange files between computers. Use Xchange Agent to automate the process of keeping files on two computers synchronized. You can even set up Xchange Agent to run automatically, when you are away from your computer. Printing to the other end of a LapLink connection? Using the Print Redirection service, you can prepare a document at home, make a LapLink connection to your office computer, and then print the document on an office printer. Sending and receiving messages? Use the Text Chat service to hold a two-way conversation with someone at another computer by exchanging written messages. You can use your modem to connect to the remote computer for File Transfer, for example, and then use Text Chat to talk to the person at the other end. Or you can use the Voice Chat service to talk to another person over the same line while using other LapLink services. Introducing LapLink Technical 11 Choose the LapLink services for the needs at hand Use File Transfer for a fast and efficient way of exchanging files. Use Xchange Agent to automate file synchronizations. Use Remote Control to run programs and access files on a remote computer. Use Print Redirection to work on a document at one end of a LapLink connection and print it at the other end. Use Text Chat to communicate with remote users, consult with coworkers, and answer users questions. Use Voice Chat to talk to another user over the same line that is being used to transmit data while using other LapLink services. Connecting to a network? Over a modem, you can connect to a network from home or on the road and use the same network resources you enjoy in the office. You can combine this remote-node connectivity with LapLink services, such as file Transfer and Remote Control. As a remote node, for example, you can direct a document youve prepared away from the office to a network printer, read and answer your e-mail, and browse the network. In the same session, you can use LapLink to run a database program on your office computer and work on large, shared files on the networkor connect to another network computer and review a presentation in preparation on that computer. ½ Go to topic summary Saving time and protecting your computer Simplify connections by storing telephone numbers, passwords, and other information in Address Book entries. Then select an Address Book entry, and the connection will be opened for you. Use SpeedSync when updating files, especially over slower devices like modems. Instead of sending entire files, SpeedSync sends only the parts that have changed since the last update. Overall times for transferring files can be cut drastically. Set up your security system to define who has access to your computer and what services they can use while connected. Use encryption to protect information you transfer over the Internet or wide-area networks. 12 Chapter 1 Getting help When you need help getting your work done, use the LapLink online Help system.

To learn more about a server or to change the phone number or select a different modem, click Properties. To set up a new connection, click New Connection and follow the instructions on your screen. When you make a Dial-Up Networking connection in LapLink, you use the Dialing Properties feature of Windows. Through the settings you specify in Dialing Properties, you determine how your calls are dialed. Use these settings to charge a call to a calling card, use your computer while traveling, reach an outside line, and place long-distance and international calls. Dialing Properties replaces the Suffixes and Prefixes feature of earlier LapLink versions. 32 Chapter 3 Connecting by modem Using Address Book for modem connections Making entries in Address Book simplifies the process of making modem connections and opening service windows. Use Address Book entries to store phone numbers, requests for services (such as File Transfer and Remote Control), and passwords. When you dial a connection, this information is passed on to the remote computer for you. In addition, Address Book entries work in combination with Dialing Properties, the Windows feature you can use for dialing outside lines, using calling cards, and placing long-distance and international calls. Go to illustration¾ Address Book is a convenient way of storing all the information you need to make a modem connection. Enter the information once, and it will be there whenever you need it again. Your Address Book entries will be available when you connect using Connect over Modem. By creating Address Book entries, you can also take advantage of Dialing Properties, the Windows feature that lets you determine how your numbers will be dialed. Set up your Dialing Properties to charge a call to a calling card, use your computer from various locations, reach an outside line, and place long-distance and international calls. For more information about Dialing Properties, see the Windows documentation. To create an entry in Address Book for a modem connection: 1 Click the Address Book button on the LinkBar. If you have set up password protection for your security system, you are now asked to type the password. s The information you store in Address Book will be sent automatically to a remote computer when you dial.

Since LapLink Technical supports TCP/IP networks, you can connect any two computers that have dialed in to the Internet. That means you can use the LapLink services (such as File Transfer and Remote Control) anywhere in the world, all for the cost of a connection to a local Internet provider. Go to illustration¾ Requirements for using LapLink over the Internet Before you connect over the Internet, both Windows NT and LapLink must be properly configured: s In Windows, the Microsoft TCP/IP protocol stack must be installed. Do not install any other TCP/IP stack. In LapLink, the TCP/IP port must be enabled in Port Setup. s Making a LapLink connection over the Internet How you make a LapLink connection over the Internet depends on how you access the Internet. There are two common ways of accessing the Internet: s s Over a modem connection to an Internet provider. Over a direct connection from a corporate network. To open a LapLink connection by modem over the Internet: 1 In LapLink, dial in to your Internet provider: click the Connect button on the LinkBar, and then click Dial-Up Networking. The Connect over Network dialog box appears when you connect. s To prepare a computer to receive incoming Internet connections by modem, start LapLink and dial in to your Internet provider using Dial-Up Networking. 2 On the TCP/IP Addresses tab of the Connect over Network dialog box, type the remote computers Internet (IP) name or address in the TCP/IP Name or Address box. (For information about Internet names and addresses, see the next section.) 3 Specify the services you want to open at the start of the connection, such as File Transfer and Remote Control. 4 Click OK. To open a LapLink connection over the Internet from a corporate network: 1 Start LapLink. 2 On the LinkBar, click the Connect button. Then click Network. 3 Click the TCP/IP Addresses tab. 4 Type the remote computers Internet (IP) name or address in the TCP/IP Name or Address box. Connecting to Other Computers 35 Making a LapLink connection by modem over the Internet On the LinkBar, click the Connect button. Then click Dial-Up Networking. Type the phone number of your Internet provider, if necessary. When the Connect over Network dialog box appears, type the Internet name or address of the computer to connect to. For information about Internet names and addresses, see the next section. ½ Go to topic summary 5 Specify the services you want to open at the start of the connection, such as File Transfer and Remote Control. 6 Click OK. To prepare a computer to receive incoming Internet connections over a corporate network, enable the TCP/IP port in LapLink Port Setup. Then leave LapLink running. To simplify repeat connections to a computer with a permanent Internet address, create an entry in Address Book. Identify the connection type as TCP/IP. s To use your network for LapLink connections over the Internet, the network must have Internet access, your computer must be configured with Microsoft TCP/IP software, and the networks security system must allow LapLink connections. Consult your system administrator if in doubt. 36 Chapter 3 Connecting over the Internet Determining an Internet address To connect to another computer over the Internet, you must know the computers Internet name or address. Conversely, anyone wanting to connect to your computer, must know its Internet name or address. A computers address on the Internet can vary from session to session, or it can remain constant, depending in large part on how the Internet is accessed. With access to the proper software, however, names can be used instead of addresses; names do not change from session to session and thus simplify the process of connecting. Go to illustration¾ When you connect to another computer on your local network, you choose from a list of connections available to you. When you connect over the Internet, however, you must provide the computers Internet (IP) address or name; there is no list of computers to choose from. Connecting to a computer with a temporary Internet address s Internet addresses consist of a series of numbers, with periods as separators: for example, 255.255.255.255. If you connect to an Internet provider by modem, its likely that your Internet address is assigned dynamically; that is, its different every time you connect. (Check with your Internet provider if in doubt.) To open a connection to a computer having a temporary address, you have a choice: s Someone determines that computers address after connecting to the Internet, and e-mails you the information. You then type that address in the Connect over Network dialog box. (If someone wants to connect to your computer, you must determine your own address and e-mail the other party.) A better solution is available through name-resolution software, which lets you maintain a permanent Internet name even though your address changes every time you connect to the Internet. For information about the free WINS service offered by Traveling Software, see page 38. s Connecting to a computer with a permanent Internet address If you connect to the Internet directly from your corporate network, your Internet address is probably permanent. Some Internet providers also offer permanent addresses; even if you dial in to such providers, your address is the same from session to session. Connecting to a computer with a permanent address simplifies the connection process, since you always know what to type as the address in the Connect over Network dialog box. Some networks include a name-resolution service called DNS (Domain Name System), which converts permanent addresses to names. A DNS Connecting to Other Computers 37 Determining your Internet address in Windows 95 In LapLink Port Setup, click TCP/IP. Then click Configure. Your Internet (IP) address appears here. name looks like an e-mail address (for example, janed.acme.com), but never includes @. If your network uses DNS, other users can connect to your computer using the DNS name. ½ Go to topic summary Determining an Internet address To determine your Internet address in Windows 95: 1 Do one of the following: s If you access the Internet by modem through an Internet provider, start LapLink and connect using Dial-Up Networking. (See the previous section for details.) If you access the Internet directly from your corporate network, start LapLink. s 2 Click Port Setup on the Options menu. 3 Click TCP/IP Network in the Ports list, and then click Configure. 4 Your Internet address appears in the IP Address box. To determine your Internet address in Windows NT: 1 If you access the Internet by modem through an Internet provider, start LapLink and connect using Dial-Up Networking. (See the previous section for details.) 2 Click the Windows Start button, point to Programs, and click Command Prompt. 3 Type IPCONFIG and press ENTER. The TCP/IP address for that computer appears in the IP Address line. 38 Chapter 3 Connecting over the Internet Using the Traveling Software WINS server for Internet names A WINS server allows computers with temporary Internet addresses to connect using permanent names. Even though your address is different every time you connect to the Internet, other computers will be able to locate your computer by specifying your WINS name. As a free service to its registered users, Traveling Software, Inc., offers a WINS server to facilitate LapLink connections over the Internet. Go to illustration¾ Most users who dial in to an Internet provider are assigned temporary addresses. With only temporary addresses to go by, LapLink users must rely on e-mail to pass on their current addresses once they have connected to the Internet. Users who want to open LapLink connections over the Internet can overcome the issue of temporary addresses by using a WINS (Windows Internet Naming Service) server. A WINS server matches a Windows computer name to the computers current Internet address. Once users have configured their computers for the same WINS server, they can locate each other using their WINS names (that is, their Windows computer names). Traveling Software offers a WINS server as a free service to its registered users. If you are already using a WINS server, you do not have to switch to the one offered by Traveling Software. If you do switch, however, be sure to record the address of the original server; other programs may rely on that server. To configure your computer for the Traveling Software WINS server: 1 In Windows, click the Start button and then point to Settings. 2 Click Control Panel and then double-click Network. s To connect to a computer using its WINS name, type the name in the IP Name or Address box in the Connect over Network dialog box. s To connect over the Internet using WINS names, two computers must be configured for the same WINS server and the same scope ID. 3 On the Identification tab, make note of your computer name. This is your WINS name (other users will use this to connect to your computer). If necessary, edit the name to avoid duplicating the name of any computer you plan to connect to. 4 In Windows 95, click the Configuration tab, click TCP/IP > Dial-Up Adapter, and then click Properties. Then, click the WINS Configuration tab. On that tab, click Enable WINS Resolution. In Windows NT, click the Protocols tab, click TCP/IP Protocol, and then click Properties. Then, click the WINS Address tab. 5 In the Primary WINS Server box, type this address: 198.102.198.10 6 In the Scope ID box, type an identifier to be used by you and the other LapLink users you want to connect to. Connecting to Other Computers 39 Setting up the Traveling Software WINS server in Windows 95 After opening the Network option in the Windows 95 Control Panel, click the TCP/IP -> Dial-Up Adapter line. Then click Properties. On the WINS Configuration tab, type the address of the Traveling Software WINS server. Type a Scope ID. Share this Scope ID with the other LapLink users you want to connect to using the Traveling Software WINS server. Begin a scope ID with a letter and follow it with any combination of ½ Go to topic summary letters and numbers (avoiding signs and symbols). Uppercase and lowercase letters are treated the same way. 7 Click OK and restart Windows. 8 Ask other LapLink users to configure their computers for the Traveling Software WINS server. Inform them of your WINS name (step 3) and your scope ID (step 6). By using a scope ID, you speed up service and minimize the possibility of duplicating the name of another computer (duplicate names are allowed in different scope IDs but not in the same one). You also restrict your access to other computers configured with the same scope ID. (If you do not provide a scope ID, the other users should do the same.) 40 Chapter 3 Connecting over the Internet Internet security and firewalls LapLink connections over the Internet may require special configuration if either of the computers has a direct connection to the Internet over a corporate network. Before connecting over the Internet, LapLink users should ensure that their data is being encrypted before being transferred. Firewalls and LapLink The Internet has grown immensely because it is unregulated. It is also inherently unsecured. To protect their data from authorized access, corporations commonly insulate their corporate networks from the Internet with firewalls, which selectively allow data to pass between the two. Without the proper configuration, LapLink connections over the Internet will probably be prevented if either of the computers is on a private or corporate TCP/IP network. LapLink requires the use of two TCP/IP ports: one for the host (the computer receiving the incoming connection) and another for the guest (the computer opening the connection). To facilitate LapLink connections over the Internet, Traveling Software, Inc., has registered port 1547 with the Internet Assigned Numbers Authority. This port is used by the host computer. To allow LapLink connections through a firewall, a network administrator should open port 1547. With most networks, this is the only configuration required. With other networks, however, it may be necessary to specify a port for use by the guest computer. In many cases, the TCP/IP stack assigns guest computers the next available TCP port number above port 1024, and the firewall automatically allows the connection. If the firewall does not allow automatic port assignment, however, LapLink must be configured on the guest computer to request a specific port. Consult your network administrator before making this change. To request a specific port on a guest computer, add the following section to the computers LLW.INI file (the file is located in the \TSI32\LLW folder under the Windows folder): [TCPIP] ClientPort=xxxxx For xxxxx type any number between 1025 and 65535, except 1547. Using a large numberfor example, one above 30000reduces the chance of Connecting to Other Computers conflicts with another TCP/IP application. (For a complete list of registered ports, see RFC 1700.) 41 Securing your data on the Internet The Internet is a large, unregulated network. When transferring data, keep in mind that the data can be intercepted. To keep any intercepted data from being interpreted, set LapLink to encrypt the data beforehand. To encrypt all data exchanged in a LapLink connection: 1 On the Options menu, click Security. Or click the Security button on the LinkBar. 2 On the Encryption tab, check this option: Encrypt all information exchanged with a remote computer. 3 Click OK. ! Be sure to enable encryption before you open a connection to another computer. Changing the setting during a connection wont have any effect until you connect again. 42 Chapter 3 Connecting by network If youre connecting to another computer over an IPX or TCP/IP network, make sure that the other computers security settings have been changed to allow you to connect. Then click the Connect over Network button on the LinkBar to connect to the other computer. Go to illustration¾ Networks offer users (and the companies that maintain them) features for sharing files, exchanging files, sharing peripherals, and exchanging electronic mail between computers. A network can link two computers across a room or thousands of computers and a wide variety of peripherals in several buildings. If youre using a network, you can use LapLink to connect with other computers on your network. In the same LapLink session, you can also connect to other computers using a cable or modems. s To connect two computers over a network, both must be running LapLink, and the network ports must be enabled. Connecting to another computer by network Before you can connect to another computer on the network, security settings on that computer must be relaxed. If you are going to accept incoming LapLink connections, your computers security settings must be relaxed. See page 56. To connect to another computer by network: 1 Click the Connect button on the LinkBar, and then click Network. 2 In the Available Now list, click the name of the computer you want to connect to. If the computer is not listed and you are attempting to connect over a TCP/IP network, you can access it though its IP name or address. See the next section for more information. 3 Under Services, click the services you want to use, such as File Transfer and Remote Control. 4 Click OK. s If your network port is not yet enabled, the Port Setup dialog box appears when you connect. Filtering the list of available network computers You can display the name of a particular computer in the Connect over Network dialog box by typing all or part of the name in the Computer Name Filter box; then click Refresh List. Specifying the name of a particular computer can speed up the process of opening a LapLink connection when you are connecting to a network by modem, using Dial-Up Networking. Connecting to Other Computers 43 Connecting by network Click the Connect button on the LinkBar. Then click Network. Click the name of the computer to connect to. Click OK when you are ready to open the connection. Click Refresh List to update the list of connections. To locate a particular computer, type its nameor part of its namehere. Then click Refresh List. Click the services you want to use. To display the names of all available computers again, click the arrow next to the Computer Name Filter box, click All Computers, and then click Refresh List. Before you can connect over your network, you must have your network drivers loaded, though you dont have to be logged on to the network. After connecting to a network using Dial-Up Networking, use the Connect over Network command to connect to other network computers. Note that you can open such connections only over a network with a dedicated Novell file server. On a network, each computer name used in LapLink should be unique. To avoid conflicts, use your network log-in name. Use Address Book in LapLink to make connecting easier. If you regularly connect to the same computers, add those computer names to Address Book. For more information, see page 46. ½ Go to topic summary 44 Chapter 3 Connecting by network Connecting to computers outside of your TCP/IP subnetwork Only computers on your local TCP/IP subnetwork appear as available connections when you attempt to connect by network. To connect to a computer beyond your subnetwork, click the TCP/IP Addresses tab in the Connect over Network dialog box and type the IP name or address. Go to illustration¾ TCP/IP is the protocol used to connect to wide-area networks and the Internet. Each computer on a TCP/IP network has a unique address. You dont need to know this address to connect to other computers on your subnetwork; the names of these computers appear in the list of available connections when you connect. You can connect to a computer outside of your subnetwork (on your wide-area network or the Internet) by specifying its IP address or name. An IP address consists of numbers (such as 255.255.255.255). A name consists of a string of characters (such as janedoe.acme.com). It is often similar to an e-mail address but never includes the @ symbol. To connect to a computer outside of your TCP/IP subnetwork: 1 Click the Connect button on the LinkBar, and then click Network. 2 Click the TCP/IP Addresses tab. s For information on making a LapLink connection over the Internet, see page 34. s You can use an IP name only if there is a server available to resolve (translate) the name into its real IP address.
