I'm using autossh to connect to a reverse SSH tunnel. I run it from startup.
However, I was facing problems in that the tunnel sometimes goes down.
I created a script which checks if the tunnel is actually working , and if not do other stuff like restart the modem.
The only way I seem to be able to check if the tunnel is working is by using the autossh command again and checking the reply.
autossh -M 0 -N -q -o ServerAliveInterval=20 -o ServerAliveCountMax=3 HMzg8fYGfW11oJ7Jl6BCTT2lYrB@fw1.sshreach.me -i id_rsa -R 13212:localhost:22 -v
I just noticed tho that every time I use this autossh command, it starts a new auto process. There are so many autossh processes running now. This is obviously not good.
There are two questions :
1) Is there a better way to verify if my tunnel is working without using the autossh command again? (I couldn't find another way)
2) The other option I suppose is to kill the processes in my script which are not used and just have the one autossh process. However, How do I find the pid of a process if there are many of them with the name autossh?
Thanks in advance
