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

$ wezterm ssh [email protected]

(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 new tabs or panes will each 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.

The ssh_backend configuration can be used to specify which ssh library is used.

wezterm is now able to parse ~/.ssh/config and /etc/ssh/ssh_config and respects the following options:

  • IdentityAgent
  • IdentityFile
  • Hostname
  • User
  • Port
  • ProxyCommand
  • Host (including wildcard matching)
  • UserKnownHostsFile
  • IdentitiesOnly
  • BindAddress

All other options are parsed but have no effect. Notably, neither Match or Include will do anything.

{{since('20210502-154244-3f7122cb:')}}

Match is now recognized but currently supports only single-phase (final, canonical are not supported) configuration parsing for Host and LocalUser. Exec based matches are recognized but not supported.

Include is now supported.

CLI Overrides

wezterm ssh CLI allows overriding config settings via the command line. This example shows how to specify the private key to use when connecting to some-host:

wezterm ssh -oIdentityFile=/secret/id_ed25519 some-host
