I recognise that I will probably have no choice but to force reset the server in question, but I wonder if anyone can offer any insight as to why this is happening.

I can ssh into my Virtual Private Server just fine.

I can even resume my tmux session!

$ tmux a -d

I notice my weechat client seems to have frozen. Not to worry, I'll kill it from another tmux window. Time to find that process ID.

$ ps aux

Weird, it's printing nothing. Perhaps the problem is in tmux. I'll detach and try some other commands.

$ ls

Nothing at all? What's going on? Well it printed some things when I logged in, so some things must work...

$ uname

It does sound like your VPS is locked up sort of. I would request a reset to your host and see if that helps out. – kobaltz Oct 5 '11 at 18:53

Try blind-typing "reset" and "stty sane". It is possible that the commands are in fact returning data but the terminal settings are such that it isn't displayed.
