Like last event, LinuxTag is not responsible for the network. It is set up by T-Systems, contractor of Messe Berlin.


Network at the exhibition area

Wired network at projects' booths

T-Systems will provide a separate LAN for all projects booths. This will be a private Class B network with about half of the IPs distributed via DHCP with relatively long lease time (about 1 day). The other half of the address space will be distributed using peg-dhcp where each booth/project will be given at least its own 256 static addresses (see RFC-2322 for further details).

There are always some "experts" who provide their own DHCP service to all other projects, which results in a big network mess. To be on the safe side, we advise you to use your PEG-DHCP address pool for your booth's systems. To make this clear: it is not allowed to run a DHCP server within our network.

Please notice: the whole network will be behind a NAT router and some ports to the Internet will be blocked - especially many of the unencrypted protocols like telnet, pop3, imap or smtp. Please use their encrypted matches (ssh, pop3s, imaps, submission/smtps).

Required equipment

LinuxTag provides per three free project booths a 100 MBit, RJ45 Ethernet connection as link to the conference network. The projects have to share this uplink among their neighbours and have to bring with their own switches for deploying our network on their booth.
The projects also have to bring their own network cables. You have to wire your entire booth on your own, including the cables to all counters. LinuxTag will provide you with protectors against stumbling across the cables. Please ask our team to help you securing your booth after you fitted everything to your needs.
If you think you need a private network, please bring an own router with you. It should use one of the assigned static IP adresses for your project. But be aware: the conference network is also behind a NAT router.


We kindly ask you to refrain from setting up an _unencrypted_ network to the public at your booth. If you really think it is necessary to have a local wireless network at your booth, please encrypt it and do not give the encryption key to our visitors.

Workshops, tutorials and developer room

All workshop rooms, tutorials, and the developer room share another class B network. In each room you can either use our DHCP server, which should provide your system with all required information, or you can use one of the static IP addresses we have assigned to the rooms.

Wireless network access

In addition to this there will be a wireless network available mainly in the conference area. The SSID of our wireless LAN is LinuxTag. You have to accept our terms and conditions once per day and for each MAC address.


In case you encounter any problems with our network, please contact the front desk at our office located in hall 7.1b., or call +49 (30) 3038-81566 and ask for someone of the NET-Team.
