Network Layout
This page will show the network topology & proposals for network expansion / modification.
External IP address 92.27.61.158.
External domain address lspace.nottinghack.org.uk (DNS record looked after by 'RepRap' Matt)
Internal IP address range with reserved IP's available from 10.0.0.2 - 10.0.0.99 and DHCP allocation from 10.0.0.100.
External Port Routing
| Service | External Port | Internal Port | Internal IP | Notes |
|---|---|---|---|---|
| HTTP | 80 | 80 | 10.0.0.2 | Webserver on Holly |
| SSH | 1921 | 22 | 10.0.0.2 | SSH on Holly |
Static IP's
These are assigned via DHCP/MAC using Kryten
| IP | DNS Name | Notes |
|---|---|---|
| 10.0.0.1 | kryten | Router |
| 10.0.0.2 | holly | Our always on server |
| 10.0.0.90 | marvin | Laser Printer |
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 :)
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 now set up on 10.0.0.90 as marvin. And it works!
