How to send SIGINT to a remote process over SSH?

Question

I have a program running on a remote machine which expects to receive SIGINT from the parent. That program needs to receive that signal to function correctly. Unfortunately,

Answer 1

$ ssh -t foo.bar.com gdb
...
(gdb) ^C
Quit

Answer 2

Can you run a terminal on the remote machine and use kill -INT to send it the signal?

Answer 3

Try signal SIGINT at the gdb prompt.

Answer 4

It looks like you're doing ctrl+c. The problem is that your terminal window is sending SIGINT to the ssh process running locally, not to the process on the remote system.

You'll have to specify a signal manually using the kill command or system call on the remote system.

or more conveniently using killall

$killall -INT gdb
