Able
Albe is Kryten's borther the Linksys ADSL2MUE modem that talks to the outside world.
Running in PPPoA bridge mode Kryten passes the talktalk login detail to Able.
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
Note this router is on long term from Tony S until the hackspace has something better - feel free to donate an upgrade ;)

Marvin
Marvin the Paranoid Android
According to Marvin, "The first ten million years were the worst, and the second ten million years, they were the worst too. The third ten million I didn't enjoy at all. After that I went into a bit of a decline." Apparently, the best conversation he'd had was over 40 million years ago, and that was with a coffee machine.
The HP Laserjet 4 Plus is set up on 10.0.0.90 as marvin.
We have a few spare toners but donations towards paper usage are more than welcome.
Nottinghack.org.uk
The main Nottinghack website is run for a dedicated linux server located in Florida provided by 'RepRap' Matt
This hosts the Wordpress blog, this wiki, the Nottinghack Planet, and all the external DNS recordes for Nottinghack domains, we have nottinghack.[org.uk|co.uk|com]
The Twitterbot for @HSNOTTS is also hosted on on this server.
HackSpace Instrumentation
The Network and Holly provide the backbone to our HackSpace Instrumentation projects.
Naming
See here for our naming convention
ADSL Connection Reboot Procedure
If for some reason the internet connection is not responding! The Kryten and Able are located on the Internet shelf on the Members Storage room On Able check if the 'DSL' and 'Internet' lights are green If not on then reboot Able by cycling power using the power switch on the back, If two minutes after doing this the 'DSL' light does not come back on then you can also cycle power on Krtyen If there's still no look, it could well be an outside issue with talktalk.
Extra Equipment
