checking servers

norc check <domain...> connects to servers directly, without an account, and reports what they offer before the login: TLS, login mechanisms, stream features, and whether they allow in-band registration. The registration form is requested, nothing is registered. Service discovery is tried too, though most servers only answer it after the login.

norc check conversations.im 404.city
norc check --json $(cat servers.txt) > servers.jsonl     # one JSON object per server and line
jq -r 'select(.registration == "open" or .registration == "captcha") | .domain' servers.jsonl

registration	Meaning
open	in-band registration is open (registrationFields: the fields asked for)
captcha	open, with a CAPTCHA to solve
web	registration on a website (url)
closed	the server doesn't allow registration (registrationError)
unsupported	the server has no in-band registration
unknown	none of these

Servers are checked one after another, each at most --timeout seconds (default 20); --port sets another port. error is set if a server couldn't be reached (or has no TLS). Exit code 1 if any server failed.
