'ssh -R 12345:localhost:22 server.com "sleep 1000; exit"' forwards server.com's port 12345 to your local ssh port, even if you machine is not externally visible on the net.
This one blew my mind
This one blew my mind
ssh -fN -o ServerAliveInterval="240" -R 2222:localhost:22 example.com
This lets you easily keep the tunnel open long-term. Why?
-f Background the ssh process (don't need nohup)
-N Don't run any command
-o... Make ssh do the work of keeping the session alive forever'sshfs_mount' is not really stable, any network failure will be troublesome'
To avoid trouble with remote backups and other long running processes, I always add the following to the end of ~/.ssh/config or /etc/ssh_config:
Host *
ServerAliveInterval 300 while [ true ]; do sleep 1000; done
sleep 1000; exit
I enjoyed your list.
