Technical – On campus
•
Originally SOWN was an ad-hoc Mesh
network
•
Now we have some campus nodes which
use iSolutions’ network to talk to the
Internet and the rest of SOWN
•
Currently there is one high powered node
working atop of SUSU
•
Run embedded PCs with Voyage Linux or
OpenWRT
•
High powered (>400mw) miniPCI wifi
cards

Technical – Servers
•
Rack mount servers located in building
32 (EEE)
•
sown-auth – does what it says on the
tin – This server is our authentication
server for Web Redirect and 802.1x.
We are directly peered with University
login servers and through them to
eduroam
•
sown-vpn – Responsible for handling
back-haul links from remote nodes so
that they can talk to auth
•
sown-nat – allows access to the
internet for users of the on campus
nodes and for all machines to update
online etc. Also runs SNMP and cacti
to make pretty graphs

Technical – SOWN[at]HOME
•
Plug’n’Play wireless access points to allow SOWN access to be broadcast from
users house with the minimum of fuss
•
Just plug it in to a free network port on your router and switch on!
•
Makes use of home ADSL line for internet access
•
Tunnels are set up to sown-vpn so SOWN network access is granted.
•
User authentication is passed down the tunnel to sown-auth
•
Nodes are made by Meraki, but run with our own flavour of OpenWRT (linux
distribution for home routers) which is configured to work with SOWN

SOWN Part 2
What are we currently researching?
• WiMAX – we are shortly going to be the second city in the
UK with this bleeding edge technology
• Multicast – SOWN TV?
• VoIP – Internet phone in your home
