SSH Connections

wezterm uses libssh2 to provide an integrated SSH client. The client can be used to make ad-hoc SSH connections to remote hosts by invoking the client:

$ wezterm ssh wez@my.server

(checkout wezterm ssh -h for more options).

When invoked in this way, wezterm may prompt you for SSH authentication and once a connection is established, open a new terminal window with your requested command, or your shell if you didn't specify one.

Creating a new tab will create a new channel in your existing session so you won't need to re-authenticate for additional tabs that you create.

SSH sessions created in this way are non-persistent and all associated tabs will die if your network connection is interrupted.

Take a look at the multiplexing section for an alternative configuration that connects to a remote wezterm instance and preserves your tabs.
