== Switch port assignments ==
=== Netgear Prosafe FS728x ===
The switch in the members storage room is a Netgear FS728TP (24x 100mbit with [http://en.wikipedia.org/wiki/Power_over_Ethernet 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.

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 [[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 VM on [[Collective]] running [http://www.pfsense.org pfSense], it handles all our DHCP and routing from the external world.<br/>
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.<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:Daniel|Daniel]] directly<br/>
 
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.<br/>
 
For more details see the [[Network/VPN|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.<br/>
 
==== 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. <br/>
 
==== [https://spacefed.net/wiki/index.php/Spacenet spacenet] ====
Cross-hackspace wireless network, using WPA2 Enterprise. Login using: <br />
Username: ''&lt;[[HMS]]-username&gt;''@nottinghack.org.uk <br />
Password: ''&lt;[[HMS]]-password&gt;'' <br />
 
For more details, see [[spacenet]].

===[[Holly]]===

===[[Collective]]===

===[[Andromeda]]===
See [[Andromeda]]
 
=== [http://en.wikipedia.org/wiki/WOPR 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.  <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/>
 
There are 2 user accounts -<br/>
"David" - not password protected, but limited access - suitable for web browsing / printing etc.<br/>
"Falken" - admin account - speak to [[User:Tony_S|Tony_S]] if you need the password.<br/>
 
=Genral Use PC=
===[[Quorra]]===
A powerful workstation with dual heads, Quorra is available for all members to use.
 
=Printers=
=== [http://en.wikipedia.org/wiki/Marvin_the_Paranoid_Android Marvin] ===
Marvin the Paranoid Android
<blockquote>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.</blockquote>
 
The HP Laserjet 4 Plus is set up on 10.0.0.90 as marvin.<br/>
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.<br/>
The printer feeds A4 paper from tray 2 and A3 paper from tray 3.<br/>
A duplexer is installed enabling double-sided printing.<br/>
 
=== B4 ===
The Brother MFC-5460CN is set up on 10.0.0.92 as B4.<br/>
Printing and copying in colour, and scanning via "Control Center 3" software on [[Quorra]] when running WindowsXP, or Xsane if running Linux.<br />
 
The scanner on B4 is installed and shared on [[JARVIS]], and can be used from other Linux machines by adding '<code>Jarvis</code>' to the '<code>## saned hosts</code>' section of <code>/etc/sane.d/net.conf</code> (see [https://help.ubuntu.com/community/sane.d%20tutorial#Step_1:_Set_up_your_Linux_clients_to_use_this_shared_scanner Ubuntu documentation] for more details).
 
=== Plotter ===
HP DesignJet 600
Not networked, but connected via serial or parallel interface to [[quorra]]
 
=Websites=
 
=== [http://nottinghack.org.uk Nottinghack.org.uk] ===
 
The main Nottinghack websites are run form [[Andromeda]].
 
This hosts the [http://nottinghack.org.uk Wordpress blog], [http://wiki.nottinghack.org.uk this wiki], [http://planet.nottinghack.org.uk the Nottinghack Planet]
 
The [[Twitterbot]] for @HSNOTTS is also hosted on on this server.
 
===[http://lspace.nottinghack.org.uk lspace.nottinghack.org.uk]===
 
Hosted locally at the space on [[Holly]] <br/>
 
Includes:

DNS record looked after by [[User:Lwk|'RepRap' Matt]]
 
===[http://cacti.nottinghack.org.uk/graph_view.php 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!<br/>
Then Able is located on the Internet shelf on the Members Storage room<br/>
On Able check if the 'DSL' and 'Internet' lights are green<br/>
If not on then reboot Able by cycling power using the power switch on the back,<br/>
If two minutes after doing this the 'DSL' light does not come back on then you need to get in touch with either [[User:Lwk|&#39;RepRap&#39; Matt]] or [[User:Daniel|Daniel]] who can check on Kryten<br/>
If there's still no look, it could well be an outside issue with talktalk.
 
== Extra Equipment ==
See [[Network/Equipment|here]] for a list of our other network gear
