very simple lan question

[Aaron Maxwell <amaxwell@phy.ucsf.edu>]

Hi, I have two boxes (one woody, one potato) with ethernet cards,
connected by a RJ45 cable.  I'd like to be able to ssh/sftp betwixt them. 

[I admit I don't grok networking much yet (that's partly why I'm doing
this, to learn).  I've mainly been reading the Net-HOWTO and the man pages
for ifconfig, if(up|down), route, and references therein; let me know if
there's another FM I should RT.]

I've given the two boxes, 'leper-messiah' [1] and 'yomama', which I've
given addresses 192.168.0.0 and 192.168.0.1 resp; and I've edited
/etc/hosts on each box appropriately.   The file
'leper-messiah:/etc/network/interfaces' contains the stanza
  iface eth0 inet static
      address  192.168.0.0
      netmask 255.255.255.0
The file 'yomama:/etc/network/interfaces' contains this stanza
  iface eth0 inet static
      address  192.168.0.1
      netmask 255.255.255.0
I've gotten the eth0 interface working fine (I think) on both.  For
example, on yomama, 'ifconfig eth0' yields
yomama:~# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:C0:F0:47:A9:A1  
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          Interrupt:11 Base address:0xdc00 
I've enabled the appropriate services in /etc/services on both machines,
I'm pretty certain, so I don't believe that's the problem.

I tried various manipulations of the routing table, but they didn't seem
to help.  I'm not sure what other info is useful, so please ask.

Thanks in advance.
Aaron
