Top 30 SSH shenanigans
Good list of commands to be SSH ‘Yoda’. I like the tunnels and screen the most in these. They have been so useful over the years, for development and troubleshooting.
Here is a short list that I use ofter:
# Copy SSH public key
$ ssh-copy-id user@host
# Alternative for ssh-copy-id
$ cat ~/.ssh/id_rsa.pub | ssh user@machine “mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys”
# Start a tunnel local:2001 -> remote:80
$ ssh -N -L2001:localhost:80 somemachine
# Run a GUI app from remote machine
$ ssh -fX <user>@<host> <program>
# SSH to machien behind NAT
$ ssh -NR 0.0.0.0:2222:127.0.0.1:22 user@jump.host.com
