LapLink refers to the computer at the other end of the connection as the remote
computer (also known as distant computer ). Other programs sometimes also use
this designation for the client.

Remote access
Access from one computer to another remote computer is referred to as remote
access .
Preparing
You have seen that a host offers services that other computers wish to make use of. This
requires preparation of both the host and the client(s).
The host
First, of course, you need to configure a computer that will make an offer to the clients.
The procedure is as follows:
a
One computer in the company is required for remote access. It should preferably not
be directly used by employees.
If this computer is in the local area network (LAN) of the company, the clients will
also have access to all free resources and services in the network. This is conveni-
ent for the employees but in principle also involves the risk of unauthorized access
to the LAN. Therefore: Don't forget the security settings!
To enable other computers to establish a connection to the host, the host must natu-
rally be “wired“ in some way. In this example, you select a modem or an ISDN
modem with which to establish telephone connection.
b
Install LapLink on this computer as described in the chapter 'Communications Soft-
ware'. The security settings are now set up so that no one can access this computer.

After the installation you click directly on Options
E
Security... . For the security
of your system you can distinguish between
– private system: No one may access the host (makes no sense for the host but
does for the clients)
– protected system: Only the users agreed in the access list can access the host
– public system: Anyone can access the host (dangerous, particularly if the host is
on a LAN).
