So if you boot into the broken system and connect via serial cable what does the output of /sbin/ifconfig eth0 say ? Is there no IP address configured, or is it set to the wrong one ? If it is set incorrectly there may be some startup script which has some old/stale values set. You could try to add a set -x to some of the startup scripts, so that they echo the commands they execute regards marc -- You received this message because you are subscribed to the Google Groups "casper@lists.berkeley.edu" group.
