I have been looking for solutions to some of these things forever: 21) Have an ssh session open forever autossh -M50000 -t server.example.com ‘screen -raAd mysession’ Open a ssh session opened forever, great on laptops losing Internet connectivity when switching WIFI spots. 24) Transfer SSH public key to another machine in one step ssh-keygen; ssh-copy-id user@host; ssh user@host This command sequence allows simple setup of (gasp!) password-less SSH logins. Be careful, as if you already have an SSH keypair in your ~/.ssh directory on the local machine, there is a possibility ssh-keygen may overwrite them. ssh-copy-id copies the public key to the remote host and appends it to the remote account’s ~/.ssh/authorized_keys file. When trying ssh, if you used no passphrase for your key, the remote shell appears soon after invoking ssh user@host. 25) Copy stdin to your X11 buffer ssh user@host cat /path/to/some/file | xclip
