Switch port assignments

Netgear Prosafe FS728x

The switch in the members storage room is a Netgear FS728TP (24x 100mbit with POE + 4x gbit ports), the switch in the workshop is FS728TS (same, but with no POE). As far as possible, both switches should have identical configuration; I.e. if the studio switch fails, the workshop switch should be a drop in replacement.

Dell PowerConnect 2724

The Dell switch is in the members storage room, just above collective. It is connected to the Netgear FS728TP and to most of the Studio network sockets.

Server Naming

See here for our naming convention

Network Devices

Able

Able is Kryten's brother the BT Openreach VDSL modem that talks to the outside world.

Kryten

Kryten is VM on Collective running pfSense, it handles all our DHCP and routing from the external world.
It is connected to VLAN 4 for access to Able, and 2 for the main hackspace network.

The Nottinghack VLAN has access to local resources - e.g. a samba file-share on JARVIS, a future 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 Daniel 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

WiFi

There are three WiFi networks:

HSNOTTS

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

HSNOTTS_GUEST

WiFi for guests is setup as HSNOTTS_GUEST and passcode can be provided and this will (possibly at some point) run on a separate VLAN.

spacenet

Cross-hackspace wireless network, using WPA2 Enterprise. Login using:
Username: <HMS-username>@nottinghack.org.uk
Password: <HMS-password>

For more details, see spacenet.

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.

Genral Use PC

Quorra

A powerful workstation with dual heads, Quorra is available for all members to use.

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, or Xsane if running Linux.

The scanner on B4 is installed and shared on JARVIS, and can be used from other Linux machines by adding 'Jarvis' to the '## saned hosts' section of /etc/sane.d/net.conf (see Ubuntu documentation for more details).

Plotter

HP DesignJet 600 Not networked, but connected via serial or parallel interface to quorra

Websites

Nottinghack.org.uk

The main Nottinghack websites are run form Andromeda.

This hosts the Wordpress blog, this wiki, the Nottinghack Planet

The Twitterbot for @HSNOTTS is also hosted on on this server.

lspace.nottinghack.org.uk

Hosted locally at the space on Holly

Includes:

DNS record looked after by 'RepRap' Matt

cacti.nottinghack.org.uk

Also hosted locally on Holly this provides graphing of various stats and info (mostly temperature graphs) from the hackspace instrumentation

http://hollyvm/

Our intranet, only accessible from the hackspace network

HackSpace Instrumentation

The Network and Holly provide the backbone to our HackSpace Instrumentation projects.

Other Info

ADSL Connection Reboot Procedure

If for some reason the internet connection is not responding!
Then Able is 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 need to get in touch with either 'RepRap' Matt or Daniel who can check on Kryten
If there's still no look, it could well be an outside issue with talktalk.
