My 8.0 system has been running great up until Monday evening when users started reporting they were unable to connect. Sure enough, I couldn't even connect from my LAN. I rebooted, looked at messages from dmesg, and saw nothing unusual--nothing that said networking couldn't start, or there was a hardware failure, nothing to indicate a problem. What should I check next?
As always, thanks in advance. I learn so much just by casual browses of messages on this list. If I made a career of Debian sys admin, I'm sure I'd get all my knowledge fromlearn everything I need to know from here. It's a great resource.
