Why LapLink?

apLink 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 of fice, and beg in your workday as usual, by tackling your e-mail.

While finishing your orange juice, you read your messages, write new ones, send replies—in ot her wor ds, you operat e much as you would in the of fice. You’re using LapLink. In particular , you’re using Remote Control, one of the LapLink services, to operate your of fi ce computer fr om home .

On your home monitor you see what you would h ave seen had you commuted to work, and you operate your e-ma il program as you would have fr om the of fice. You can even use your home printer for those messages you’ll review later.

Forget to get the late st copy of a file bef ore leaving th e office? Move to File T ra nsfer, another LapLink ser vice, and drag the file from the folder on t he of fice n etwork to its location on your hard drive at home. Since you’re updating a file already on your home computer, the file is transferr ed almost before you know it. (In fact, La pLink merely upda tes the file, transferring only t he parts th at have chan ged.)

Returning to Remote Cont rol, y ou star t a n etwork applic ation and access the company’ s huge product database. Just as you thought, customers ordered more blue widgets last month than during the previous two m onths combined ! More grist for the quarter ly report you’re working on .

While you’re still connected, you check out a rumor. Is the competition really selling their widgets at cutthroa t prices? Connecting over the dedicated Internet line in the office, you visit the competition’s W eb 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-d ay business tr ip.

Suppose you’re on a business trip

Settling into your hotel room, you take your e yes off the view long enough to discover a de dicated digit al phone l ine. All the better to connect to your office computer , fir st 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. Y ou 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 annu al report ?

Now you’re looking at her mo nitor and t alking to h er at the same time, using another LapLink service, V oice Chat. After some discussion and trying this and that , the t wo of you agree: make the logo larger and reverse the colors. She’ll have a finished draft wa iting for you on the network in an hour.

. . . Why LapLink?

In an hour , h owever, you expect to be at your favor ite Ch icago restaurant, choosing from the dessert menu. On your way out the door, you schedule LapLink to reopen t he connection with the office and synchronize folders on your laptop with folders on the of f ice networ k.

By the time you return to your hotel room, LapL ink will have exchanged the quarterly repor t you finished on the r ed-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.

Staying in touch with the office

hone lines, modems, and LapLink: these are the basics necessary to connect to the office from home or elsewhere. T o these basics you can add a network, a network server, even the Internet. Y ou deter mine how to connect by considering your office setup and what you want to accomplish when you are connected.

Connecting to the off ice requir es that your home comp uter or your laptop have a modem and a ph one line t o connect to. It must also be ru nning LapLink .

Depending on the availability of a network and the Int ernet in your office, you can th en make any or all of the se kinds of connections:

• To your office computer directly

• To your office computer or another office computer through the off ice netwo rk

• To your office computer through the Internet

Connecting directly to your office computer

If your office computer is equipped with a modem, you can connect to the computer directly, using C onnect over Modem.

Turn on th e modem a nd leave Lap Link running w hen you leave the office. T hen connect thr ough t he modem and r un programs and transfer files as you would normally .

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.

Connecting to the office network

If your office has a network, you ca n connect to t he network and then to any computer running Lap Link on the network , including your own. In fact, you can access any ne twork resources normally available to you from t he of fice. If you browse the Internet from your desk at work, f or example, you can browse it from afar, too.

To connect to the office network, simply dial in to a dedicated network dial-up server u sing Dial-up N etworking.

Connecting over the Internet

Many workstations now have direct Int ernet access over dedicated, high-speed connections. I f your of fice com puter is one of these—and you have Inter net access fr om your home computer or your laptop—you can connect to the office using Connect o ver Int ernet.

. . . Staying in touch with the office

Using Connect over Internet is like conn ecting 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 t he of f ice, yo u can save m one y on your long-distance connectio ns to the of fice.

• If you connect to the Intern et over a high-speed line while you’re away fr om t he office, you can improve t he speed of your conn ecti on to t he o f fice .

Before connecting over the Inter net, set up your of f ice computer for Internet access by publishing its addr ess through the LapLink Internet dire ctory. Then be sure to leave LapLink running.

Connecting without running LapLink

There may be times when you n eed to connect to your office computer runnin g LapLink f rom another compute r that doesn’t have LapLink installed. You can transfer files between these two compute rs using Surf Up.

Just like other Internet connections, you must f irst publi sh your office computer’s Internet address. Then, to connect to the office computer, you go to www.laplink.com/surfup and enter the Internet ad dress.

Once you’re connected you can view files an d folder s, download files to the local comp uter or upload files to your office computer.

Connecting at the office

ith 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 tr ansfers. 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.

Connect to other computers on your network

If your office is equipp ed with a local networ k (LAN), you can connect directly to any other network computer r unning LapLink using Connect over Netwo rk. Because LapLin k connections over networks are fast, they are id eal for sending large amounts of data in a short time .

Suppose it’s your job to distr ibute files to several computer s every Tuesday. To automate the operation, create an Xchange Agent file by showing La pLink which files to copy and where to copy them. When T uesday a rrives, ru n the Xchange Agent yourself or schedule it to run unattended, at a time when the computers are usually idl e. LapLink automatically connects to th e computers , transfer s files to the designated folders, and disconnects, all withou t assistance.

It may also be your job to main tain those computers. With out leaving your desk, you can use R emote Con trol to t roubleshoot problems on other computers, chatting with their users, if necessary.

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: u pdate file s on your laptop before you leave; update files on your desktop when you return.

To update files on either computer , att ach a LapL ink cable and run LapLink on both computers. A connection opens automatically.

Y ou could then locate the most rece nt files, whether on the laptop or the desktop, and copy them to the other computer . Instead, you create an Xchange Ag ent to p erform t he operation automatically . Y ou also set up LapLink to run th e agent whenever you start LapLink.

In the future, simply attach the cable a nd run LapL ink 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 Inter net and ope n connections. By combining LapLink and the Internet, you can connect to computers anywhere in the wo rld.

Before you use Connect over Internet , other LapLin k users will set up LapLink on their compu ters so that their e-mail addresses, or other unique identifiers, are “publishe d” through an Internet direct ory as their Int ernet addresses. They then notify you of their ne w addresses.

Once you go online and run LapLink, merely supply a com puter’s Internet address to locate the computer an d open a connection.

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.

Connecting directly by modem

sing modems and a phone line, you can connect to another computer or to an of fice network. 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).

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 La pLink computer, you have access to all the programs an d files availabl e to that

computer (including any network r esources if th e computer is logged on to a network).

. . . Connecting directly by modem

Connecting through a network

Once on the network, you can conne ct to ano ther LapLink computer and use LapLink services just as you would in a direct modem-to-modem connection. But there’ s mor e. When you dial in to a netwo rk, you can also:

• Connect to any LapLink computer on the netw ork, not just one. (You can even transfer files from one computer to ano th er.)

• Access all the network resources ava ilable to you in the office. If you norma lly browse th e Internet ove r the network, for examp le, yo u can do t he same t hin g from a remote location, using the browser on your loca l computer.

• Enhance security by combinin g LapLink pa ssword protection with network securi ty.

For a Dial-Up Networking connection, your o ffice ne twork (either TCP/IP or IPX) must h ave a dial-up server. (If in doubt about your network, ask t he netwo rk administrat or.)

Using Dial-Up Networking, you dial in t o the n etwork through this server .

• The LapLink security setu p of the comput er you are connecting to must be changed to all ow incomin g connections. See page 42.

• LapLink must be running on both computers.

• Modem ports must be en abled in La pLink on both computers.

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 R emote C ontrol), password, and other per tinent information.

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.

T o connect to another computer by mod em:

1 Click the Connect button on the LinkBar , and th en click

Modem.

2 In the Connections list, click the connection you want to

open. The connections listed under Manu al Dial are your

Address Book entries for modem conne ctions. 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, an d countr y codes, you can type the phone number without creating an Address Book entry beforehand. Lap Link dials the number exactly as you type it, regardless of how you have set up Dialing Properties.

T o dial manually:

1 Click the Connect button on the LinkBar , and th en click

Modem. 2 Click Manual Dial. 3 In the Phone Number box, type the number to dial. 4 Click the Dial button.

Dialing in to a network through a network server: Dial-Up Networking

se 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 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.

Y ou can also connect to LapLink computers on the Inter net and browse the Internet using the In ternet connection in the office. In short, you can access the same net work resources you use in the office.

Before you use Dial-Up Networking

• Dial-Up Networking , a Windows feat ure, must be installed on the computer you di al from. See Windows help for instructions.

• Your network must have a dedicat ed di al-up se rver (such as Novell N et Ware Connect, Windows Remote Access Server, or Shiva NetMode m) . T he comp ut er you connect to must be connect ed to an IPX or TCP/I P

3 For information about det ermin ing an IP addres s, see

page 27.

Using Address Book for modem connections

aking entries in Address Book simplifies the process of opening the same direct modem connections time after time. In your entries you store phone numbers, requests for services (such as File T ransfer and Remote Control), and passwords. When you use Connect over Modem, this information is passed on to the remote computer for you. Y ou can also set up entries for connections you make to network computers after you dial in to a network using Dial-Up Networking.

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 comp uter using Connect over Modem.

Address Book works in tandem with Dialing Propert ies, 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, o r place lo ngdistance and international calls. For more infor mation about Dialing Properties, see Windows help.

T o create an A ddress Book entry f or a Connect over Modem connection:

1 Click the Address Book butto n 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.

. . . Using Address Book for modem connections

4 In the Connection Type list, click Modem. 5 Under Phone Number, type the area code and phone num-

ber, and click the country code. 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 Y ou can change you r selections later , as part of the connection process. Y ou 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.

Y ou can lock a host (blank its screen or disabl e 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 e ntry. If you want to create anoth er entry, click Add again and complete t he entry. Otherwise, click Close.

Using Address Book for dial-up connections to network computers

For LapLink connections you make aft er dialing in to a ne twork, set up Address Book entries t o store requests for services and security information. This information is passed to the network computer aft er you connect to a net work using Dial-Up Networking.

As the Connection Type, use Network: Available Now if the computer normally appears in the list of available comp uters 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 dif ferently). F or connection s to othe r computers running LapLink Gold, type p asswords in capital or lowercase letters exactly as t hey were t yped on th ose computers.

NOTE Passwords in LapLink Pro, L apL ink Tech, or LapLink 7.5 or earlier are not case-s ensitive. In Add ress Book entries for connections to an y 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 se nsitivity, Address Book entries created in an ear lier LapLi nk version may no longer let you connect to computer s that hav e also been upgraded. Have n ew pa sswo rds set up o n t ho se comp uters; then change your Ad dress Boo k en trie s t o matc h.

Connecting over the Internet

onnect 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.

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 Co ntrol, File T ransfer, and any of the other LapLink services you wo uld use when conn ected directly by modem—often at reduced cost. For the easiest

Internet connections, use Conn ect over Internet and supply the Internet address the remote computer has published through an Internet directory like the one hoste d by LapLink.

. . . Connecting over the Internet

Before you use Connect over Internet

• Both computers must be conn ected to the Inter net.

• The remote compute r (the one you ar e connecti ng to) must have its Internet address published through an Internet directory. See page 22.

• The security setup o f the re mote comp ut er must ha ve been configured to allow inco ming conn ections. See

page 42.

• The TCP/IP ports must be en abled in LapLin k on both computers. See page 135.

• LapLink must be running on both computers.

Using Connect over Internet

T o connect to a nother LapLink comput er on the Internet:

1 Connect to th e Inte rnet as u sual. 2 Click the Connect button on the LinkBar, and then click Inter-

net.

3 If you have created an Address Book entry for the connec-

tion you want to open, click the connection in the Connections list.

1 If you are out of the office and without access to the Inter-

net, dial back to the of fice netwo rk and us e the of fice In ternet connection. See page 26.

2 If you are out of the office and without access to a com-

puter with LapLink software, you can use LapLink Surf Up to connect. See page 50.

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 Inte r-

net 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 o ver Internet, you can set up Address Book entries to store Internet addresses, requests for ser vices, and security in formation. All of this is passed on t o the ne twork compute r 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.

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 we b of T CP/IP networ ks.

When you use Connect over Network, you must supply the computer’s IP address, not an address published throu gh 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 Netw ork, see page

26.

Making a computer available for Internet connections

nternet connections, like e-mail messages, need addresses. T o 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 Inter net is easy—w hen you know their IP addresses. But IP addresses can be hard to determine, and they oft en change. If you dial in to an Internet service provider, for example, your computer may be assigned a different IP address ea ch time you g o online.

So how do you make your computer available to ot her LapLink computers on the Inter net? You have your e-mail address (or other unique identifi er) “published” as your Internet address. You then let other LapLink users connect t o your computer by telling them your Internet address.

NOTE If the computer is behind a firewall, there are additional requirement s. See page 24.

. . . Making a computer available for Internet connections

Use LapLink to specify the address t o be publ ished and when it will be published—for example, whenever you are using LapLink on the Internet .

Use the LapLink Internet directo ry to publish yo ur address; the directory is available without cost to LapLin k users, a nd you don’t have to sign up to use it.

NOTE Publishing your Int erne t add r ess doe s n ot op en your computer to u nwant ed co nne ctions. La pLi nk users who know your published address can connect; othe rs cannot, even if they are using Net Meeting or other programs that rely on Internet director ies.

T o set up Lap Link to have you r computer’s address published on the Internet:

1 On the Options menu, click Inter net 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 log-

in 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 con firmation dialog box, clear this box: When Manually Publishing My Address , Show Co nfirmat ion.

• To have LapLink publish your address for yo u, check this box: Automatically Publish My Address Whe n 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 com puter’s I nt erne t

address, you must also cha nge its se curit y se tup b ef ore other computers can con ne ct over th e I nt ern et. Fo r mor e information, see page 42.

Publishing your Internet address

Y ou 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.

T o publish your Internet address your self:

1 Connect to th e Intern et as u sual. 2 On the Connect menu, click Publish My Internet Address.

Making an Internet connection to a computer behind a firewall

f 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.

. . . Making an Internet connection to a computer behind a firewall

Y ou must configure bot h computers before you can make a firewall connection. F irst, configure the compu ter inside the firewall to accept incoming connection s using eithe r a Login List or configuring a Public System (Log-in List is more secure) and then create an Address Bo ok entr y.

Y ou must also create a Log-in list en try on the computer outside the firewall. This entry must mat ch the Address Bo ok entry you created on the computer inside the f irewall.

NOTE If you are sharing yo ur co mpu te r w ith so meone other than yourself, you will need to coordinate t he firewall configuration with th at other pe rson.

Before you connect to a computer behind a firewall:

• Both computers must be conn ected to the Inter net.

• The computer inside the fir ewal l must publish its Int ernet address through the LapL ink Inte rnet dir ectory server . S ee page 22.

• The computer inside the firewall must have an Addr ess Book entry that includes the uniq ue comput er name, user name, and password f or the com puter outside t he firewall.

• The computer outside the firewall mu st be configured to allow incoming connection s. See page 42.

• The TCP/IP ports must be ena bled in Lap Link on both computers. See page 135.

• LapLink must be running on both computers.

NOTE For additional security, LapLink allows users to change the port n umber that the y want to connect through. For more informat ion ab out Variable Port Allocatio n, see the readme file loca te d i n t he LapL ink Gold ap plica tion directory.

Connecting to a co mputer behind a firew all:

1 Connect to th e Intern et as u sual. 2 Click the Connect button on the LinkBar, and then click Inter-

net.

3 If you have created an Address Book entry for the connec-

tion you want to open, click the connection in the Connections list.

Otherwise, click Manual Connect. Ty pe the Internet address, log-in name, and p assword for the computer behind the firewall.

NOTE You can get this information from the ow ner of t he computer behind t he f ir ewall.

4 Under Services, check the services you want to use. 5 Click OK.

Connecting over an office network

onnect to any other computer running LapLink on your office network (LAN) and use Remote Control, File Transfer , or another LapLink service. Use Connect over Network and click the name of the computer you want to connect to or supply its network address.

Use Connect over Network to link computers on an office network.

Y ou can click the name of a computer or switch to the TCP/IP Addresses tab and type the computer’s IP address.

Y ou can open a LapLink connection to a nother computer on your office network, whe ther it is a n IPX (Novell N etW a re) network or a TCP/IP network.

NOTE To simplify routine connections over a netw ork, cr eate Address Book entries. See page 28.

Y ou can often open a network connection simply by clicking the computer’s name in a list of La pLink computers o n the network. To open a connection to a computer tha t lies outside your portion (subnet) on a TCP/IP ne twork, how ever, you must provide the computer’s TCP/IP address. (There is no list to choose from.)

. . . Connecting over an office network

Before you use Connect over Network

• The security setup of the remote computer ( the one you are connecting to) must be config ured to allow incoming connections. See page 42.

• The network ports (either TCP/IP or IPX) must be enabled in LapLink on both comput ers. See page 133.

• LapLink must be running on both computers.

NOTE Not only does Conn ect ov er N etwo rk w ork ov er local networks, it also connect s over the Inte rnet. F or details see page 21.

T o connect to another computer by network:

1 Click the Connect button on the LinkBar , and th en click

Network.

2 In the Connect over Network dialog box, click the name of

the computer you want to connect to. If the computer is not liste d and you are attem pting to

connect over a TCP/IP network, click th e TCP/IP Addresses tab. Then do either of the following:

• In the Connections list , click the name of the com-

puter you want to conn ect to.

• Under TCP/IP Na me or Address, type the IP address

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 L ist.

Using Address Book for network connections

implify the process of opening connections by making Address Book entries for network computers you frequently connect to. In each entry you store the kind of network connection, the kinds of services (such as File Transfer and Remote Con trol) 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 comput er’s network (TCP/ IP) address. When you create an Address Book en try for a network connection, you designate which of the tw o types of connections you are using:

• Network: Available Now For connections that appear in the lis t of curr entl y availa ble con nect ion s.

• Network: TCP/IP Address For connections that require a TCP/IP ad dr ess.

. . . Using Address Book for network connections

T o create an entry in Address Book for a network connection:

1 Click the Address Book button on the LinkBar and then

click the Add butto n.

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 comp uter’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.

Y our requests for services in Address Book will be honored only if the security setup of the remo te 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.

Y ou can lock a host (that is, blan k its screen or disable it s 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 T o edit an entry in Address Book, click the entry, and then click Edit. To copy an entry for revisio n as a n ew entry , click Copy. To delete an entry, click Delet e.

Entering passwords

LapLink Gold passwords are case-sensitive (i and I, for example, are treated diff erently). I n Address Book entries for connections to other computer s running La pLink Gold, type passwords exactly as they were typed on those computers, using capital letters and low ercase letters as necessary .

NOTE Passwords in LapLink Pro, L apL ink Tech, or LapLink 7.5 or earlier are not case-sensitive. For connections to computers run nin g any of t hese e arlie r vers i ons, type passwords in ALL CAPITAL LETTERS. If you have old Address Book ent ries fo r such co nne ctio ns, re type their passwords i n a ll capi tal le tt ers.

NOTE Because of the change in case se nsitivity, Address Book entries created in an ear lier LapLi nk version may no longer let you connect to computer s that hav e also upgraded. Have n ew pa sswo rds set up o n t ho se comp uters; then change your Address Book entrie s to match versions.

Connecting by cable

hen you connect two computers by LapLink cable, attach the cable—serial, parallel, or USB Network—to both computers and start LapLink on both computers. Autoconnect, the default setting for cable connections, opens a connection automatically . To manually connect, click the Connect button on the LinkBar, and then click Cable. To make a USB cable connection, click Connect Over USB Network.

The blue LapLink serial cable has two connectors at one end, but only one connector is attached at a time: Use the larger connector if one of the computers has a 25-pin serial port. Otherwise, attach one of the smaller connectors to each computer.
