Another problem with network

Tue Jun 27 17:55:16 UTC 2006

I just installed kubuntu and everything went well. The only problem (so 
far) is that I can't ping or ssh to my other computer. I can ping and 
ssh into kubuntu from the other linux computer.

I can ping localhost (kubuntu) and I am on dialup and can use the net 
without problem.

Here is ifconfig:

the /etc/ssh/ssh_config files are identical on both computers;

jerry at backup:~ $ cat /etc/ssh/ssh_config
#       $OpenBSD: ssh_config,v 1.20 2005/01/28 09:45:53 dtucker Exp $

# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

Here is /etc/hosts:

jerry at backup:~ $ cat /etc/hosts
127.0.0.1 localhost backup
192.168.1.10 backup.jerrysdomain.com backup
192.168.1.50 main.jerrysdomain.com main

Here is the result of ssh:

I did have both modules 8139too and 8139cp install, and blacklisted 
8139cp as andreas explained in another thread. I did reboot.

Here is the relevant part of lspci -v:

I also installed etherape but get error messages; "no suitable device 
found"     when I start it from gui.

jerry at backup:~ $ etherape

I have been googling and cannot find a solution. Any help would be 
appreciated.

Thanks
