Networking

• 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.

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.
