Hi, little more info, I did manage to break something :)
my sparc boxes are clustered, so after doing the upgrade on the master node (my last email) I did: # for i in `members`;do ssh -f $i apt-get -qq -v upgrade;done Three out of the eight remaining boxes choked (on glibc I think, though might have been ssh) with "sh: /dev/tty: Device not configured" this left ssh broken. using alternative connection methods I was able to get an interactive session and redo "apt-get update" which fixed ssh. Don't know if that relates to you're situation at all... -Jon
