This Wednesday hacking features a special:
Shared Network Infrastructure in Hausmannsgate 34
This workshop focuses on the setup we use in Hausmania to share connectivity in a open net on cable and through wireless access points. We will go through the different hardware components and the software we use: a ADSL Nextgentel router connected to a Soekris Net6501 Debian Linux box running dnsmasq to distribute ip adresses on multiple virtual subnets trunked to a managed Dell switch. We will also go through the script we use to limit the upstream bandwidth in order to avoid congestion, and the shaping model we use to define different classes of services. The setup is not optimal yet, and there is plenty of space for improvement. The challenge is the impossibility to communicate directly with the users, the need for an open and shared network, the restraints we have to implement in order to give everyone enough connectivity without penalizing the others. We do not block any type of traffic, but we have to find an algorhythm that allows a fair distribution of the resources.
Attending this workshop can give the privilege to contribute to the setup with ideas, help, inspiration, and getting root passwords. Hausmania has a very big net with 15Mbit daily traffic peaks, and no SLA!
At the same time, the normal Wednesday hacking will be going on, which include hacking, chatting and coffee. Bring your own project or use one of the available computers. There is some electronics equipment for you to use.
No registration required whatsoever, just stop by and say hello!
Door will be open from 5pm, the network workshop starts at 6pm.
