Kryten

Kryten is Linksys WRT54GL running DD-WRT VPN Build, he handles all our DHCP, routing from the external world and WiFi.

Kryten has a 4 port switch - Holly takes 1, Marvin takes 1 & the external switches take 2, leaving 8 ports on the external switches available.

WiFi for Hackspace SSID: HSNOTTS passcode uses WPA2 protocol AES encryption. Members only, passcode on request, changes to the passcode will be posted to the members only Google group.

WiFi for workshops will be setup as HSNOTTS_OPEN and only be available when needed passcode will be provided on the day and this will run on a seperate VLAN.

The Nottinghack VLAN has access to local resources - e.g. a future NAS file-share , a local dropbox server for projects & collaborations, a backup of all Web / Wiki files (to allow a remote restore in the event of moving hosts / outage of services) and anything else we don't want to be web facing.

The VPN (when enabled) would allow remote management of the VLANS, which could come in handy in the event of issues with the client WiFi access point.

Router management username & password only for Authorised members only. If there something you need changing ask on the member group or speak to 'RepRap' Matt or Tony

Usual rules apply, as to any tool - if you don't know how to use it / don't do anything :)
