Technical – On campus
• Originally three on campus nodes, back links using 802.11a, this is now replaced with the SOWN VLAN (over ISS Ethernet)
• Currently: SUSU node (on a pole on the West Refectory building) running
• Zepler with 802.11a (and soon b as well)
• Run embedded PCs with Voyage Linux/OpenWRT
• High powered (>400mw) miniPCI wifi cards

Technical – Servers• Rack mount servers located in building
32 (EEE)
• sown-auth – runs web server and database for nodes and users, and sends out config and other services related to this. Lots of very important stuff on here
• sown-vpn – responsible for all the vpn tunnels and also VPN into and out of SOWN VLAN, and Nagios network monitoring
• 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 – More Servers!
• Servers in Zepler (also used to back up other servers)
• sown-6core – IPv6 router for SOWN
• sown-vpn2 – Development server for testing
• Used for testing, before rollouts on main servers (e.g: Nagios)

Technical – SOWN[at]HOME
• Wireless access points to give out to users with no/minimal config necessary to allow SOWN access to be broadcast from users house
• 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 tunnel to sown-auth
• Nodes are from Meraki, but flashed with OpenWRT (linux distro for home routers) and then configured to work with SOWN
