installing on a machine

  1. open the install tab and download tuck-install.sh.

  2. give it a read, then run it:

    sh ~/Downloads/tuck-install.sh

  3. connect with any alias: ssh workshop.

aliases work everywhere ssh does, so scp, sftp, rsync and git pick them up too.

what it changes​

  • keys and hosts go in ~/.ssh/tuck/.
  • one Include line goes at the top of ~/.ssh/config, after a backup.
  • the script deletes itself, since it holds your keys.

run it again any time to update. to undo everything:

sh ~/Downloads/tuck-install.sh --remove

what gets skipped​

tuck only writes options that tune a connection, like Port, ServerAliveInterval or Compression. a host is skipped if it has:

  • an option that runs a command, forwards things or relaxes host-key checks, like ProxyCommand or ForwardAgent.
  • an alias with a dot, or one another host already uses.
  • a line break in any field, or a value starting with -.

the install tab lists anything it skipped.
