 Well, for no good reason, a reboot once I was back at the machine fixed
 the issue.  I'm not sure why; I didn't change anything.  I hate not
 knowing why reboots fix things. :(

Argh!!!  I did see in a google search that someone else had the problem
and a reboot fixed it too.

If it ever happens again I'd wonder if all new SSH sessions experience
the same problem and if so, if restarting the SSH daemon fixes it too.

Or if it's some weirdness with the psuedo-tty system.

 Which looks right, but when I try to use Ctrl-C, this happens:

Very strange (as someone else said.)

Only thing I can think of is that something in your startup scripts
(.profile, .bashrc, etc.) are doing something different between the
two logins.

I've seen that most often when they do things based on TERM and it's
different between a local login and remote.

Maybe make sure your startup scripts run with a 'set -x' at the
beginning and compare the output?

Good luck,

Todd

[gentoo-user] Ctrl+C not working over ssh?

2011-05-24 Thread Andy Wilkinson
I can't say for sure when this started, as I have gone a while without

I'm not even sure where to start looking.  Googling didn't find me much

Check the sshd settings of the remote machine.

That's so strange...

I'm curious, if you open another terminal and issue SIGINT to that
process (using kill), does it work? I think it should be the
equivalent to hitting ctrl-c interactively.

trap command can be used in scripts to block certain signals... I
wonder if your profile/bashrc/or something has a trap entry. But if
that's the case I would guess that the same problem would happen
locally, and not only remotely (unless remote session uses a different
shell or something). Just a W.A.G. :)
