Skullspace internal network is fine but needs better organization and documentation, see tasks section. Occasional issues connecting to the main skullspace SSID. Internet connection has occasional issues when the SkSp or AW routers have trouble getting an IP, this is being troubleshooted.

Internet is furnished by VOI, goes to the internet switch where multiples routers and servers connect. There is a main router for the main Skullspace network; this connects to a 24-port gigabit switch which has a few sub-switches in different rooms. There are APs around Skullspace with SSIDs beginning with "skullspace" and some near the fire escape connected to dishes outside, with different SSIDs.
+
<strike>The main router is a RB450G, connected to the main switch (port 2), security switch (4, later), internet feed (3), and other networks later. Main internal switch is a 3Com4924 in the server rack, feeds a GS108T at the lounge PC and a 5-port GigE switch near the meeting table. The main HP AP has SSID skullspace and is mounted on the roof in the middle of the space.</strike>

Primary: Internet from VOI (wifi-based Ubiquity NB5, tested 60mbit down 20mbit up to Speedtest.net Winnipeg, with large packets) comes from a drop in the middle of the space, connects to line #?? below the drop, goes to the server room where its PoE is; afterwards goes to the primary internet switch. We have permission to use a few IPs (currently being assigned by DHCP, but that may change - that's why they have the small white Microtik router) and a 'reasonable' amount of bandwidth.

Runs
 +
A1+B1: from rack to wiring area on top of bathrooms, A2+B2 from wiring area on top of bathrooms to pole in front of classroom. One will be used to feed wifi AP.
 +
C+D: from rack to next to a couch in lounge area. A wire goes under the nearby door to the wiring area of the space next door and above a window for the temporary garbage-cam.
 +
E+F+G: from rack to area behind rear black desk.
 +
 
 +
 
 +
== Tasks ==

The above runs were conservative - in many cases only a single drop because we were low on cat5, when it'd have been preferable to put 2 drops to be prepared for the future - but they still total up to 2000ft of cable, and quite a few hrs of wiring work.

| Being able to bind to port 22 vs having some other port forwarded by vmsrv.skullspace.ca will make this much easier to get users for. Plus, Mak has brought with him a many users from his own system where he used to have his own users with shell accounts. They're already used to port 22 and a different hostname pointing here. Leaving that alone will help keep them. That old system was taking up it's own IP address anyway.

== King's Head Pub AP ==
 
−
 
−
A popular meeting space in Winnipeg, 1 block away from Skullspace, which doesn't have wifi - but we can see the rear of its brick building from Skullspace. So we used a donated Cisco Aironet 1100AP, modified it for external antenna connection, ran some LMR400 cable outside the fire escape door and up the fire escape ladder, and pointed a 19dbi dish towards the pub. SSID is SkullSpace-dish-aimedatKingsHead, ask a member for the password. It doesn't work at all in the south main-floor area, but it does have coverage in most parts of the north main-floor area. Speedtests: 1 to 4mbit down on a laptop with a good wireless card (Atheros N). Attempted to replace the Cisco 802.11B card in the AP with a 802.11G upgrade card (AIR-MP21G-A-K9), but it became almost impossible to connect - likely because Cisco was becoming involved with Broadcom at the time that G card was made, the latter is known for the low sensitivity and receiver quality of their chipsets.
 
−
 
−
Plans to increase coverage:
 
−
*upgrade 19dbi to 24dbi antenna - only issue is they're huge and a lot of windload to put on the fire escape ladder (especially if they ice up in the winter), would prefer a roofmount pad. We'd need to calculate that the smaller beamwidth of the higher-gain antennas doesn't lose coverage of the edges of the King's Head - this math would be size of Kings's Head building x distance = degrees of view?
 
−
*add antenna receive diversity - again, the second antenna would be better on an additional (spaced farther apart horizontally) roofmount pad; vertical diversity on the fire escape ladder wouldn't help as much.
 
−
*move antenna - currently the view (all the way up the fire escape ladder) to the front of King's Head is blocked by a concrete building. 5-10ft south on a roofmount would be ideal.
 
−
*add an amplifier or a higher-power radio. The Cisco puts out 100mw, have a 500mw amplifier. Since this isn't an omni but a highly directional antenna, we could maybe classify it under the rule that allows 24dbi gain and 24dbm power output (500mw is 27dbm, but we're losing 3 db in the 40ft of LMR cable and connections, which brings us nicely to 24dbm).
 
−
*ground the fire escape ladder - would be a good idea.
 
−
*check that the antenna and LMR cable/connections are running at full efficiency - this is old gear from a garage.
 
−
 
−
Signal in the North-main floor area is currently -82 to -87 when connection is possible, with all of the above it'd be good to get it to mid-70s numbers which should allow for pretty good coverage, considering we're a block away and going through thick brick/concrete.

If ever we need to reset the main router, these will be put back in, so keep them updated.

  • Please keep an updated copy of this page printed out and posted in the server room, so there is access to documentation even if the network / internet is down
  • Also see IT Policies
  • We have many people working with the equipment, remember to attach or tie down anything that could get unplugged/fall/etc. We twice lost internet - first time the router fell and power switch got pressed, second time the power plug was pulled out of main internet switch.
  • this page is finally being updated for Sksp2, old page is at Networking/Old


High-level description

The main router is a RB450G, connected to the main switch (port 2), security switch (4, later), internet feed (3), and other networks later. Main internal switch is a 3Com4924 in the server rack, feeds a GS108T at the lounge PC and a 5-port GigE switch near the meeting table. The main HP AP has SSID skullspace and is mounted on the roof in the middle of the space.

Built using ASCIIFlow - http://asciiflow.com/

Internet feeds

B: Internet from LES.net (wifi-based Ubiquity, tested 94.83mbit down, 96.22mbit up to Speedtest.net Winnipeg)
B: Internet from VOI (wifi-based Ubiquity NB5, tested 60mbit down 40mbit up to Speedtest.net Winnipeg).

Network hardware

  • Mikrotik Routerboard 450G as main router
  • Netgear WNDR3700 router, donated by Project Bismark. It had a problem (routed packets fine but services like DHCP/DNS/web server didn't work) so was taken out of the network to test.
  • Linksys WRT54G2 v1.5 as spare. WAN port may sometime have packet loss.
  • Linksys WRT350N with DD-WRT v24SP2 firmware as a spare. Lent by Stef.
  • Linksys WRT54G v2 with tomato 1.28 firmware as a spare. Lent by Stef.
  • A 3Com 4924 (:A0) as the main switch, by default everything connects here.
  • A 3Com 4924 (:??) a spare switch.
  • 2 D-Link DWL-810+ bridges.
  • Netgear GS108T as the lounge switch.
  • D-Link DWL-7100AP AP.
  • D-Link DES-3224 as a public IP switch, set to management only on port 7 (Telnet, username "D-Link").
  • A Belkin F5D8236 wireless-N router as spare
  • 3 Cisco Aironet 1100 APs with .B cards and one (:90) with a .G card as spares.
  • Belkin F5D5141-5 switch.
  • Cisco 2950 switches #1 and #2.
  • Mikrotik RB750 (small white box) VOI's router
  • Western Multiplex Tsunami 100 5.8ghz - two links (4x IDU, 2x high ODU, 2x low ODU) unused. Panel antenna loaned from Seccuris.

Wiring

Runs A1+B1: from rack to wiring area on top of bathrooms, A2+B2 from wiring area on top of bathrooms to pole in front of classroom. One will be used to feed wifi AP. C+D: from rack to next to a couch in lounge area. A wire goes under the nearby door to the wiring area of the space next door and above a window for the temporary garbage-cam. E+F+G: from rack to area behind rear black desk.


Tasks

  • terminate ethernet lines correctly in a panel once we're sure server room is stable
  • label networking equipment (IPs etc) and servers, update this page for the latter
  • put read-only and full-access passwords on devices

Wireless Networks

skullspace = main SSID, usual password skullspace_rear: linksys G router in the server rack, as a backup.

Being able to bind to port 22 vs having some other port forwarded by vmsrv.skullspace.ca will make this much easier to get users for. Plus, Mak has brought with him a many users from his own system where he used to have his own users with shell accounts. They're already used to port 22 and a different hostname pointing here. Leaving that alone will help keep them. That old system was taking up it's own IP address anyway.
