SSH Hosts

Every Host in ~/.ssh/config that is a name rather than a pattern (*, ? and ! entries are skipped, a Host a b line gives two rows), in file order. Include lines are followed one level: ~, absolute and globbed operands work, a relative one is under ~/.ssh. A Match block ends the current host. The section is the file a host came from, relative to the config's directory (.ssh/config, .ssh/conf.d/work.conf).

The palette

The row is the host's name; HostName is the subtitle and a keyword, so the real name finds the alias from the root; User is an accessory and a keyword, Port a :22-style tag. A host with ProxyJump carries a via <jump> tag and the jump as a keyword. The palette is indexed: listed once, searched from the root, refreshed with cmd+r after the config changes.

With include_known_hosts on, the names in ~/.ssh/known_hosts (next to the config) come after, in a last Known hosts section: [host]:port unwrapped, comma lists split, hashed lines, bare IPs and hosts already in the config skipped.

Connect opens a terminal window running ssh <host> and hides the panel. Ping sends one echo to the HostName (else the name) with a 2 s wait and toasts the round trip (web-1.example.com: 3 ms), or why it did not answer; the panel stays open.

Keyboard

The plain command already goes through the config's ProxyJump; the -J form is for a machine that does not have your config.

Setup

An ~/.ssh/config with Host entries; ssh and ping on PATH. Nothing else.

Which terminal Connect opens:

• macOS: the terminal setting. auto takes the first installed of kitty, Ghostty, Alacritty, iTerm2, Terminal (Terminal is always there, so it is the fallback). kitty gets kitty -1 ssh host (a new OS window in the running instance when that was started single-instance), Ghostty and Alacritty open -na <app> --args -e ssh host, Terminal and iTerm2 an AppleScript that opens a window running the command, which asks for the Automation permission the first time. A terminal that is picked but not installed keeps the panel open with a toast.
• Linux: $TERMINAL, else the first of kitty, foot, alacritty, xterm on PATH; kitty and foot take the command as arguments, the others after -e.

Settings, [extensions.ssh]:

What it does not do

• Run ssh inside the panel: Connect hands the command to a terminal window and pal hides.
• Pattern hosts (Host *.example.com) and Match blocks: they are not rows, though their settings still apply when ssh runs.
• Nested includes: an Include inside an included file is not followed.
• Passwords, keys or agents: ssh's own business, in the terminal.

Platforms

macOS and Linux. The terminal is chosen per platform as above; ping's wait flag is -W 2000 on macOS and -W 2 on Linux, the same one echo.
