I want ssh to forward the SIGTERM signal to the remote command.

ssh root@localhost /root/print-signal.py

Get PID of ssh:

ps aux| grep print-signal

Kill the matching ssh process:

kill pid-of-ssh

Unfortunately only the ssh process itself gets the signal, not the remote command (print-signal.py). The remote command does not terminate :-(

How can I make ssh "forward" the SIGTERM signal to the remote command?

  • Maybe you should try to catch the signal Inside your Python script, I guess the signal is not transmitted since the script is not stopped but I can give us a hint of what's going on – Jaay Jan 31 '18 at 08:31

I think you can do the following : 

ssh root@localhost /root/print-signal.py

**Get PID of python file running **

ps aux| grep print-signal

Kill the matching ssh process:

ssh root@localhost "kill <pid>"

Here you are sending command to remote host .

Hope this solves your problem .

Send via SSH this (tested on sleep process):

$(proc=$(pidof sleep) && kill $proc)
