I ran a package update on a beowulf server last week, and now when I login via SSH I have noticed that networking appears to be partially broken. I can ping localhost, but no hosts outside of the machine, either from local subnet or external like google. There seems to be no outbound networking working.

Is there any way to recover from this, or am I stuck with reinstalling? --Tom _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
