Hey, I just posted my router ;) I have a Ubuntu Server running ZFS, a windows server, and a dedicated linux folding@home box as well. :) I can put more pics later.
Tell me more about the "Raspberry PI + DVB-C Stick to monitor network segment usage of my local internet provider" that is pretty cool… What kinda stats can you see?

Because i'm using internet via a cable modem you can monitor the network usage of your network segment. The reason is because cable is a shared medium and every single customer in your segment can see every single bit (multicast), although its encrypted. So what u can do is the following:
Take a DVB-C-Stick (i prefer sundtek.de because of its full linux support), then u tune your dvb-c stick to the same frequency as your cable modem (in europe thats usally 546 - 602 mhz), toggle modulation and use dvbsnoop to read off the statistics of the frequency-channel.
Result:
-
Yes, I understand how cablemodems and DOCSIS networks work, but I had no idea you could get a device to monitor the stuff like that! I am totally going to get one of those and set it up on one of my linux boxes!
Cool, looks like I can get a PCI-E one also. I may have to rig up some stuff to read the current DS/US channels from the cable modem and then feed that to dvbsnoop to get the infos. How are you making that graph? Are you manually doing it with RRDTOOL or is there some software out there for doing this specifically?
Thanks for the info BTW!

Cool, waiting for your stats. If you need assitance (complete ready scripts for Cisco-Modems + RRDTools) just msg me. Oh and - dont forget to monitor your signal to noise :)
-
Ok, sweet, I have a Cisco DPC 3008 so hopefully I wont need to modify the scripts much to grab the stats. It's funny, in another thread I posted on here today I asked if there was some software to grab this info from the cable modem and insert it into a DB so you can graph it over time. So, yes, I would love those scripts, thanks!
So, are you just using a coax splitter, standard -3.5dB one? Going to the DVB-C stick and the other side to the modem ?
-
No wait - its a Coax splitter for your TV-Signal, not the one for the modem. You should have a multimedia-splitter already at your wall (1x modem, 1x tv, 1x radio) you split the tv one! And yes, its a standarf 3.5dB splitter, so you should keep care of your stats. Maybe some adjustment of your cablenetwork is needed (increase the power on your cable amplifier and use an -3,5 attenuator for your cable modem).
For me it worked just out of the box, without modifying anything, because its just - 3.5dB :)IF YOU MODIFY YOUR AMPLIFIER - KEEP AN EYE ON THE SLOPE :)

Good idea for a thread. We're going to gather pictures from a variety of threads like these in the future and create some kind of micro-site showing off people's deployments. In the mean time, might as well get another thread going. :)
Here's our primary colocation facility, where this site and most of our others run, as well as the snapshot and release build servers. The firewalls are virtual in ESX, a HA pair with primary on one ESX server and secondary on another.

Sweeeeeeet :o Thats what i'm trying to accomplish but i still need more money (although my setup is already too fat for home networking) ;)

Well I can't pass up this opportunity.
Yes, I have a problem. I'm trying to cut down. ;)

haha Those aren't running the Watchguard software I presume? ;D

I'd love to say none of them are but the X-edge boxes at the top are Arm based and I haven't managed to hack a workable OpenWRT image onto them. Yet. ;)

Well I wish I had a fancy setup. Here is a a pic of my pfSense box.
SUPERMICRO SYS-5015A-EHF-D525 1U Intel Atom D525 Dual Gigabit LAN w/ IPMI Server
4 gig ram
Intel EXPI9402PT 10/ 100/ 1000Mbps PCI-Express PRO/1000 PT Dual Port Server Adapter
two 250gig WD black 2.5 inch drives mirrored
1500AV UPS (not shown) for 1.5 hours of backup time.
And for the heck of it a Crystalfontz display. :-D
Have gigabit wireless access point as well hooked up. (not shown)Don't make fun of my makeshift fan bracket (zip ties in vent). lol The system is "passively cooled" and I didn't like the 65°C so i put a case fan in and now its 40°C. Not exactly where i would want it but much better.

Heh, sounds like you guys have a slightly different cable setup over there. I have no cable amplifier, and I do not use the cable for my TV's (I use DirecTV for TV), so my coax is one single lin from the drop to the modem, no splitters no amps, nothing, its just raw right into it. So, yeah, I will be using a little simple 2-way slitter. But, my wife will be pissed if I buy the DVB-C card/stick right now so it will be a little bit. I WILL be working on making a scraper for my modem stat page, and then use that data to feed into the RRD graphs, though.

Colocation setup:
pfSense 2.1-DEV based cluster running on two TYAN Transport servers ;D
Basic information:
-
1x CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (2992.51-MHz 686-class CPU)
-
2x Intel(R) PRO/1000 Legacy Network Connection (1.0.3)
-
1x 3Com 3c905B-FX/SC Fast Etherlink XL (PFSYNC, XMLRPC via Fiber Optical)
-
real memory = 4294967296 (4096 MB)
The switching stack was built using two NETGEAR GS724TS (stacked via HDMI). The firmware is a pure pain but when tamed it somehow gets the job done. It's the cheapest stack I found and using LACP accross multiple physical units is definitely a big plus! Our provider runs LACP for our uplink as well so even the wan connection survives a dead unit :)
The entire setup is considered stable and runs for almost 13 months now w/o any service interruptions (e.g. crashes or similar).
@Home:

1x PCEngines Alix 2D13, 4GB CF

1x HP Switch 1900-8G (formely known as 3com OfficeConnect 3CDSG8)

1x APC SmartUPS 500VA (in the back)

Isn't 'Kamikaze' an OpenWRT code name?

pfSense is on the right for my home setup. White box running a Q8400 processor and 4GB RAM on a Gigabyte GA-G31M-S2L.
Its twin brother on the left is my FreeNAS server and the Dell 755 in the middle runs XBMC to my living room TV.
