# URZ: XMPP / Jabber

This source provides an overview of the instant messaging services provided by the Universitätsrechenzentrum (URZ) based on the XMPP (formerly Jabber) protocol.

## Key Service Features
- **Protocol**: Based on the decentralized XMPP protocol, allowing integration into a global network similar to email.
- **Client Support**: Any XMPP-compliant client can be used, although **Pidgin** is specifically recommended by the URZ.
- **Capabilities**:
    - Support for chatrooms.
    - File transfer capabilities.
    - Encrypted connections between the client and the server.
    - Support for additional end-to-end encryption between clients.

## Security Recommendations
The URZ explicitly states that the institutional XMPP system can be used for the exchange of sensitive data. In contrast, the use of external services such as **Skype** for sensitive university data is strongly discouraged.

## Support
Technical issues regarding the XMPP service and other Campus-IT central services are handled via:
- **Ticket System**: Hosted within the [[groupware]] platform.
- **Hotline**: Available at extension 1420.
