φ chat: faculty jabber

What is Jabber?

Jabber (XMPP protocol) is an instant messaging system whose main advantage is its open specification and distributed implementation.

To use it, you need to have a client installed, such as the multi-platform Pidgin, Gajim or Jabbim, but there are many. For Android, for example, the XMPP Jabber Client can be used.

How do I connect?

Each FI network user has created their own Jabber account (JID) in the form with a faculty password.

The connection configuration in different clients can vary, but usually you just need to select the Jabber/XMPP protocol, fill in your JID and your password.

If you need to specify a more specific configuration, use the following parameters:

  • server:
  • port: 5222 (STARTTLS) or 5223 (SSL/TLS)


This very simple client is part of the Thunderbird mail program. However, it requires different settings:

  • Server:
  • port: 5222

Discussion Rooms

Multi-user communication can be implemented using so-called conferences (chat rooms, multi-user chat, MUC). Only users from the Faculty of Informatics can participate in conferences on our server. Please note that the recordings of these conferences are archived and available to administrators. Conference rooms on FI have the address mí (usually místnost itself can be used as well). The general discussion is at

User and conference searches are services accessible via service discovery. The details vary from client to client, but use tends to be intuitive in principle.

Contacts from other servers

You can also send messages with any Jabber user connected to another server, as long as it supports and is not restricted in this respect. Just add the appropriate JID to your contacts.
