Network

This page gives the details of the space's network and connected devices. The Network and Servers group maintain and look after the network.

Network Layout

This page will show the network topology & proposals for network expansion / modification.

Network Devices

Able

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

Kryten

Kryten is VM on Unimatrix 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

Not currently running and not for member access
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.

Servers

The Collective

These are 3 HP N40L MicroServers that run the VMs within the space and act as our database cluster
See Collective

Unimatrix

Primary VM host
Hosts Kryten, Holly and Gibson

Kryten

VM running PfSense as Internet gateway and DHCP/DNS server

Holly

Our main workhorse vm, runs HMS and all the instrumentation programs
See Holly

Gibson

Our password store

Locutus

Secondary VM host
Hosts JARVIS and Rommie

JARVIS

Provides Samba file server, CUPS print server and member shell accounts
See JARVIS

Rommie

Staging server for HMS code dev

Queen

Backup Server
Does not host any VM's
Hosts Docker services nh-lighting and nh-nodered

Queeg

Fail over Monowall PC, its not much but it can keep GateKeeper running in a pinch

Dorian

RPi3 running our UniFi controller

Andromeda

This is our offsite server, hosted at Linode it run the main website, wiki, talk, and emails.
See Andromeda

Genral Use PC

Quorra

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

Fey

General-use windows PC in the blue room,aimed at CAD work and anything else requiring a reasonably beefy GPU.

WOPR

Another general-use PC in the blue room, by the window

Printers

For more details, see Printers.

Bender

The HP Color Laserjet HP5550 is set up on 10.0.0.95 as Bender.
The printer feeds A4 paper from tray 2 and A3 paper from tray 3.
A duplexer is installed enabling double-sided printing.
Bender is shared on JARVIS, so should be auto-detected by Linux machines.

Rosey

An Epson WF-7610DWF printer/scanner set up on 10.0.0.94. The scanner/printer should be auto-detected by most Linux/Mac machines, and is known to work from Quorra using Xsane.

Plotter

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

DNS record looked after by 'RepRap' Matt

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:

• Graph showing connected network device count

Hackspace Management System

The Hackspace Management System
Hosted locally at the space on Holly
see HMS

cacti.nottinghack.org.uk

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

https://holly/

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.
