Both machines should have an IP number and should know each others ip-nr,
that's the function of /etc/hosts.  For a local network a bunch of ip-nrs
is reserved 10/8, 172.?/16 and 192.168/16.  So if you put something like

   127.0.0.1       localhost
   192.168.1.1     one.localnet
   192.168.1.2     two.localnet

in /etc/hosts of each machine, the first step is made.

The second step is entering the relevant things in /etc/network/interfaces.
On machine one.localnet this should look like:

   # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

   # The loopback interface
   iface lo inet loopback

   # The first network card (network, broadcast and gateway are optional)
   iface eth0 inet static
        address 192.168.1.1
        netmask 255.255.255.0

On machine two.localnet all is the same but for the ip-nr, there the address
line of the first network card should read:

        address 192.168.1.2

Okee, w're almost done.  We need to assure that the driver for your
network card is loaded, have a look at dmesg's output (dmesg | less)
and look for a line starting with "eth0".  If it is missing, look up
the brand and model of your network card and use modconf to add the
correct driver.

And finally to make it all work (normally done at boot) on both
machines do:

   # ifup eth0

As far as I know, now "ping {two,one}.localnet" should work.
