Once you have all of these files set up, you should be able to reboot
|
|
your new kernel and attempt to use the network. There are many places where
|
|
things can go wrong, so it's a good idea to test individual aspects of
|
|
the network configuration (e.g., it's probably not a good idea to test
|
|
your network configuration by firing up Mosaic over a network-based X
|
|
connection).

You can use the <tt>netstat</tt> command to display your routing tables;
|
|
this is usually the source of the most trouble. The <tt>netstat</tt>
|
|
man page describes the exact syntax of this command in detail.
|
|
In order to test network connectivity, we suggest using a client such
|
|
as <tt>telnet</tt> to connect to machines both on your local subnetwork
|
|
and external networks. This will help to narrow down the source
|
|
of the problem. (For example, if you're unable to connect to local machines,
|
|
but can connect to machines on other networks, more than likely there
|
|
is a problem with your netmask and routing table configuration).
|
|
You can also invoke the <tt>route</tt> command directly (as <tt>root</tt>) to
|
|
play with the entries in your routing table.
|
|
<P>
|
|
You should also test network connectivity by specifying IP addresses
|
|
directly, instead of hostnames. For example, if you have problems with
|
|
the command
|
|
<P><TT> $ <em>telnet shoop.vpizza.com</em>
|
|
<P></TT>
|
|
the cause may be incorrect nameserver configuration. Try using
|
|
the actual IP address of the machine in question; if that works, then
|
|
you know that your basic network setup is (more than likely) correct,
|
|
and the problem lies in your specification of the name server address.
|
|
<P>
|
|
Debugging network configurations can be a difficult task, and we can't
|
|
begin to cover it here. If you are unable to get help from a local guru
|
|
we strongly suggest reading the <em>Linux Network Administrators' Guide</em>
|
|
from the LDP.
