I have a bunch of websites running on a year-or-so old Fedora installation. Tonight, all the sites stopped responding. I've been trying to log in to investigate, but can't, and I'm clueless about what to do.
Pinging the server works, response times are decent, ~200ms.
When I shh, the "Last login: ..." text appears, but nothing more. However, if I leave it at that, and open another ssh session, the first one actually logs in (I've got it set up to use keys instead of a password), and the new one gets stuck at "Last login: ...". I can repeat this as many times as I've tried - opening a new ssh session always makes the previously opened log in.
When logged in, the only command I can consistently run without the connection(?) freezing, is ls
in my home dir. I have been able to sudo su
once, but every other time things freeze at that, as does as running any other command (top
, killall -9 httpd
, ps aux
are some I've tried).
Does this pattern sound familiar to anyone? Any tips on how to proceed would be greatly appreciated!
