Server Naming

See here for our naming convention

Network Devices

Able

Able is Kryten's brother 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.
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 guests is setup as HSNOTTS_GUEST and passcode can be provided and this will run on a seperate VLAN. <br/ 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 for Authorised members only. If there something you need changing ask on the google group or speak to 'RepRap' Matt or Tony S directly
Usual rules apply, as to any tool - if you don't know how to use it / don't do anything :)

OpenVPN

Kryten runs our openVPN server for access to the hackspace network from the outside world.
For more details see the VPN page

Collective

Joshua

Joshua loves to play games, Tic Tac Toe, Chess, Global Thermonuclear War... all the family favourites. We've co-opted him into running Quake II, Open Arena, Unreal Tournament & Counter Strike 1.5.
The aim is to have a games server running games suitable for clients running low powered netbooks & laptops. This allows us to run LAN parties & have more people join in, without having to bring gaming rigs from home. Also QII & Open Arena have open source install paths available, with Unreal & Counter Strike available at low cost.
Joshua is running Windows XP Pro on a 1GHz PIII with 512MB RAM & a RIVA TNT2 graphics card.
Impressive I know.

There are 2 user accounts -
"David" - not password protected, but limited access - suitable for web browsing / printing etc.
"Falken" - admin account - speak to Tony_S if you need the password.

Printers

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.

Clank

The HP Laserjet 5Si is set up on 10.0.0.91 as clank.
The printer feeds A4 paper from tray 2 and A3 paper from tray 3.
A duplexer is installed enabling double-sided printing.

B4

The Brother MFC-5460CN is set up on 10.0.0.92 as B4.
Printing and copying in colour, and scanning via "Control Center 3" software on quorra when running WindowsXP.

Other Info

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.
