SSH straight into tmux

  Host example.org
 RemoteCommand tmux new -A -s default

Instead of this, i go one step further, and in .zshrc on username@example.org:

  if [ -n "$SSH_CLIENT" ] || [ -n "$SSH_TTY" ]; then
    [ -z "${TMUX}" ] && tmux new-session -A -s default
  fi

How about SSH straight into screen?

Here's how to define a shell function for quickly attaching to an existing screen session after connecting via ssh (or creating a new one if none exists):

  sshcreen () {
      ssh -t "$@" screen -xRR
  }

Works with bash and zsh. Usage is pretty simple:

  $ sshcreen user@example.com

You can use normal ssh arguments, such as the port:

  $ sshcreen root@localhost -p 2222

Detach the session with CTRL-A + D, reattach by re-running the sshcreen command you previously used.

PS: repurposed my comment from a recent discussion: https://news.ycombinator.com/item?id=32486892

I’m using the .zshrc trick too, what are the pros and cons of both? I would like to try out the RemoteCommand one though because it looks cleaner to me

Apparently the RemoteCommand way (which had never occurred to me!) can break other tools like scp or the like.

The advantage I had in mind of using the rcfile is that it's something i configure once and then applies no matter where i ssh from.

From elsewhere in this thread, it doesn’t break scp any more!

    ssh root@remotehost “apt update && apt install -y byobu && byobu-enable”

Much simpler IMO.

maybe, but it scratches a totally different itch. your proposed solution certainly doesn’t result in automatic use of tmux over ssh.

It does: that's what the byobu-enable part does. It modifies the .profile or .bashrc or whatever. All subsequent remote logins to that user account will automatically start/reattach to byobu (which uses tmux backend by default iirc).

so the same thing i did but more convoluted and requires a distro package and a service?

nah.

It doesn’t run a service, it just modifies the user’s login scripts to start byobu/tmux on login, just like yours.
