| == Server Naming ==
| |
| See [[Network/Naming|here]] for our naming convention
| |
| | |
| = Network Devices=
| |
| === Able ===
| |
| Able is Kryten's brother the Linksys ADSL2MUE modem that talks to the outside world. <br/>
| |
| Running in PPPoA bridge mode Kryten passes the talktalk login detail to Able.
| |
| | |
| === [http://en.wikipedia.org/wiki/Kryten Kryten] ===
| |
| Kryten is Linksys WRT54GL running DD-WRT VPN Build, he handles all our DHCP, routing from the external world and WiFi.<br/>
| |
| Kryten has a 4 port switch - [[Holly]] takes 1.<br/>
| |
| 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.<br/>
| |
| 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.<br/>
| |
| 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.<br/>
| |
| | |
| Router management username & password for Authorised members only. If there something you need changing ask on the google group or speak to [[User:Lwk|'RepRap' Matt]] or [[User:Tony_S|Tony S]] directly<br/>
| |
| Usual rules apply, as to any tool - if you don't know how to use it / don't do anything :)

| |
| We've co-opted him into running Quake II, Open Arena, Unreal Tournament & Counter Strike 1.5. <br/>
| |
| 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.<br/>
| |
| Joshua is running Windows XP Pro on a 1GHz PIII with 512MB RAM & a RIVA TNT2 graphics card. <br/>

| Impressive I know.</br>

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.</blockquote>

| =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.
