A fork of tmux that supports sharing sessions across the internet via SSH. See https://tmate.io/.
Note: Make sure you have generated SSH keys (e.g. id_rsa).
Also, this snap will only work if you install with --devmode. This is because of tmate's use of the setgid syscall. See https://developer.ubuntu.com/en/snappy/build-apps/debug/#common-problems.
