An average guy's IT (mis)adventures

prosodyctl shell

Launch the shell:

# prosodyctl shell

Delete pubsub node (the ">" sign at the beginning is important and also dangerous, as it lets you do anything!):

>prosody.hosts["pubsub.example.tld"].modules.pubsub.service:delete("blog", true)

Delete ALL pubsub nodes

>local service = prosody.hosts["pubsub.example.tld"].modules.pubsub.service; for node in pairs(select(2, assert(service:get_nodes(true)))) do service:delete(node, true); end

Check subscription by user:

>prosody.hosts["pubsub.example.tld"].modules.pubsub.service.subscriptions["user@example.tld"]

Change affiliation on pubsub nodes (make user owner):

>prosody.hosts["pubsub.example.tld"].modules.pubsub.service:set_affiliation("blog",true,"user@example.tld","owner")

Unsubscribe from node

>prosody.hosts["pubsub.example.tld"].modules.pubsub.service:remove_subscription("blog",true,"user@example.tld")

Subscribe to node

>prosody.hosts["pubsub.example.tld"].modules.pubsub.service:add_subscription("blog",true,"user@example.tld")

prosodyctl commands

Asking for help:

# prosodyctl shell help

List registered users:

# prosodyctl shell user list example.tld

List existing MUCs:

# prosodyctl shell muc list [component name]

Activate a component:

# prosodyctl shell host activate some.component.example.tld

Generate Invites: create a new invite using an ad-hoc command in an XMPP client connected to your admin account, or use the command line:

# prosodyctl mod_invites generate example.tld

Reset forgot passsword: "doesn't seem to work - see below"

# prosodyctl mod_invites generate example.tld --reset <USERNAME>

Automatic Certificates Import: prosodyctl has the ability to import and activate certificates in one command:

# prosodyctl --root cert import HOSTNAME /path/to/certificates

Certificates and their keys are copied to /etc/prosody/certs (can be changed with the certificates option) and then it signals Prosody to reload itself. –root lets prosodyctl write to paths that may not be writable by the prosody user, as is common with /etc/prosody. Multiple hostnames and paths can be given, as long as the hostnames are given before the paths.

This command can be put in cron or passed as a callback to automated certificate renewal programs such as certbot or other Let's Encrypt clients.

Import All:

# prosodyctl --root cert import /etc/letsencrypt/live

Reset forgot password

# prosodyctl install --server=https://modules.prosody.im/rocks/ mod_password_reset

Reload prosody configuration then use ad-hoc commands to generate a reset link for given JID

Yet another small update about gemini.

You can now browse gemini://woodpeckersnest.space even from regular HTTP, here: https://gemini.woodpeckersnest.space/

I've applied some fixes (like) to HTML and CSS (the latter is pretty much the same used by the @wpn onboarding page, but obviously customized). As for accessibility, I think it should work well for desktop and also mobile browsers; CGIs work as well.

The proxy I used is Loxy. I also already opened an issue on their repo for a problem with query strings, still waiting for someone to reply. Apart from that, everything checks out.
