If I have a tunnel opened with this command

 ssh -f root@localhost -g -L 60000: -N

Which call of netstat do I have to use to see whether the tunnel is open or not?

I am working with Linux Red Hat.


  • Do you want to know if the tunnel is available, or whether there are any connections using it? – Barmar Mar 13 '13 at 16:10
netstat -anp | grep 60000.*ssh

should do the job.
