Configuration
The files lnk exit keeps, and what each one holds. It reads no
environment variables; lnk help <command> lists the variables each
command reads, as plugin.toml declares
them.
Exit (lnk exit)
Each file is only your user's (mode 600).
~/.lnk/exit/exits.toml
The exits this computer keeps: each machine, how it's reached, who holds it, and who takes it on the socket rather than the port.
~/.lnk/exit/<machine>.log
Each exit's log, which is where to look first when an exit is down (Troubleshooting).
~/.lnk/exit/exit.sock, on the machine
The exit's SOCKS proxy, while it's up; left behind when it drops, and removed when it connects again.
