  • 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://http://asciiflow.com/

Internet feeds

Primary: 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.


New IP Ranges

  • 172.30.4.x = testing/reserved for later use
  • 172.30.5.x = half Security/Management network half VPNs
  • 172.30.6.x = Main network DHCP .100-.240 router .1 network gear .10-.29 printers .30-.39 VMs, servers .40-.99 VPNs .241-254

VOI IP usage

VOI gave us 206.220.196.48/28 (mask 255.255.255.240), 206.220.193.64/29 (mask 255.255.255.248) as well as 2604:4280:1:c0de::/64, you must reserve IPs here before using them. You'll need to plug into the new VOI-Static switch, currently a Cisco in the 'top' rack.

Access

All members currently have full access to all devices. Later it may be a good idea to have different full-access passwords for all devices restricted to NetOps and by request, and the read-only password being publically known among our members.
