3.7.2 Finding PCs on your Partner’s Network
You have now set everything on your X3200 to connect to your partner’s net-
work. Let us suppose, for example, that you now want to establish contact be-
tween your PC and the Windows BossPC in your partner’s network.
There are a few things you should know first. Every PC in your LAN or in your
partner’s network requires a unique address, the IP address. In addition to the
use of IP addresses, an alternative means of addressing PCs that developed in
the past was by computer or host names (e.g. BossPC ). Computer names are
used especially in Windows networks. PCs, however, only understand IP ad-
dresses and not names. Thus, it is necessary for the names to be translated (re-
solved) into their corresponding IP addresses (cf. chapter 4.5, page 95 ). Typical
examples of such name resolution are DNS or WINS servers. As you normally
do not want to set up your own server in a small network, there is an alternative
way of resolving the name BossPC into an IP address: the LMHOSTS file.
In the LMHOSTS file, IP addresses are arranged with their computer names in
tabular form. If, for example, you are looking for BossPC , a PC located in your
partner’s network (e.g. head office), your PC checks the LMHOSTS file for the
corresponding IP address and in this way is able to find the PC. Alternatively,
you can use DNS Proxy (see chapter 6.3.2, page 229 ).
Caution!
The following configuration can lead to increased connections and thus higher
telephone bills. The conditions that lead to connections being set up are largely
dependent on the respective network configuration. If you connect a network
drive, for example, you must expect regular requests to increase the number of
connections made.

To avoid unintentional charges, it is essential that you monitor your X3200 .
Use the Credits Based Accounting System for this purpose (see
chapter 7.1.3, page 268 ).
