I see the following in /var/log/messages whenever I reboot or restart networking.  Though it says that the network is unreachable, I can telnet, ftp, ping, etc. to and from that box.  What gives?
i have the kernel 2.2.16 and two lan cards

This could be the solution to your problem

# (added automatically by netbase upgrade)
#
# In new Debian installations, this file is deprecated in favour of
# the ifup/ifdown commands (invoked from /etc/init.d/networking), which
# can be configured from the file /etc/network/interfaces.
#
# If you are receiving SIOCADDRT errors, they can be avoided by adding
# a netmask and interface to your "route add -net" lines. eg,
#      route add -net 127.0.0.0
# becomes:
#      route add -net 127.0.0.0 netmask 255.0.0.0 lo
#
# Alternatively, these lines can simply be deleted if you don't use 2.0.x
# series kernels.
