Quite a simple one:


-f tells ssh to go to background -L binds a local port to a remote device and port -N tells ssh not to execute any commands

So use this to tunnel from local port 8000 in to a remote machine on port 22 you’d use

ssh -f user@server.test.com -L 8000:server.destination.com:22 -N

Once the tunnel is open you can use the following to ssh or scp data around

ssh localhost -p 8000
scp -P 8000 /path/to/local/file user@localhost:~
scp -P 8000 user@localhost:/path/to/remote/file .

I use ssh tunnels all the time to remote access and use one of our Solr servers that is blocked behind a firewall.
