Open ssh session in new tab using wezterm ssh?

[adamshand]

Hello,

I've recently discovered WezTerm and really enjoying using it, thanks!

I have a simple script (ssh.sh) which lets me open ssh sessions in new tabs. With WezTerm I can do this like this:

wezterm cli spawn ssh -t example.nz "cd /srv/synapse; exec $SHELL -l"

That works great, but I'd prefer to use wezterm ssh because that way if I split the tab the new pane opens up on the same host.

I can do that with this command:

wezterm ssh -o RequestTTY=yes -o RemoteCommand="cd /srv/synapse; $SHELL -li" example.nz

But that opens the new shell in new window rather than a tab.

Is there a way to open ssh sessions in a new tab and have splits automatically open on the ssh host?

Thanks for any pointers!

Cheers,
Adam.

In the latest release, wezterm will automatically populate ssh_domains from your ssh config.

If you have this in your ~/.ssh/config

Host example.nz

you'll have two ssh domains created:

• SSH:example.nz - works like wezterm ssh
• SSHMUX:example.nz - requires wezterm's multiplexer to be installed on the remote

armed with the domain name, you can do:

$ wezterm cli spawn --domain-name SSH:example.nz

to use the cli to spawn a new tab in that domain. Docs for wezterm cli spawn.

You can use CTRL-SHIFT-P (by default) to open the Command Palette and fuzzy match example.nz and spawn a connection that way, or just fuzzy match on ssh to find all your ssh hosts in there.

You can use the CTRL-SHIFT-L (by default) to open the debug overlay and then type in wezterm.default_ssh_domains() and hit enter to see the list it extracted from your ssh configuration.

Should be resolved by fa0f538 and 947d242
Those will show up in a nightly build within about an hour.

Where to put config.ssh_domain = ... exactly? I tried to put them right in .wezterm.lua but it complains about undefined variable. Thanks in advaned.

When using wezterm ssh host, it uses the ssh agent and don't ask for my ssh passphrase, but wezterm cli spawn --domain-name SSH:host do ask for the passphrase.

When there are 100s or 1000s of hosts to log on to, it doesn't make sense to add them all to .ssh/config. I am in that situation; the way I have my SSH configured is to use wildcard based rules that setup multiple jump rules etc. OpenSSH CLI works really well in this fashion.

Any chance to spawn the OpenSSH command rather than using the rust implementation?

What I was hoping to achieve was to use a key mapping to invoke a lua function that somehow asks for hostname to connect to and opens a new tab or pane; a workaround for #5800
