Polycom Power
I have a 501 with traditional power and a 301 with PoE. I rightfully assumed that the traditional power from the 501 would work on the 301. How do I get the PoE to work? Do I use the Polycom PoE cable in addition to whatever PoE injection method I use? I have a Cisco PoE injector that works on my Cisco AP350 and my 7960. No combination of this injector, the Polycom cable, and the phone result in

Cheap PoE switches/injectors?
I'm trying to spec out hardware for a new office, and I'd like to include power over Ethernet as an option. I've seen a handful of PoE injectors around $1000 for 24 ports and a couple switches up around $2500 for 24 ports. Are there any cheaper options, short of buying a boatload of 1-port injectors off of ebay? I don't really need more then 24 ports of PoE out of 48 total

Cisco power injector with GXP2000 phones
I've tried to use a Cisco power injector to supply power over Ethernet to a GXP2000 phone without success. Although when I plugged these phone to a PoE capable Cisco Switch it worked without a problem! Knowing that all these three equipments implement IEEE 802.3af protocol, why doesn't it work with the Cisco power injector? Anyone also had this problem before? Thanks, Ricardo Carvalho.

cisco poe
I know this is on the wiki, I just want to confirm so I don't blow up my cisco phones. I've got several cisco 7940's all running using cisco power cubes. However, my boss wants me to switch just a few over to poe, but doesn't want to fork out the dough for a nice cisco poe switch, or anybody else's poe switch for that matter. So my question is, what is the '99.999%

Polycom 501 power over ethernet
When I bought two Polycom 501 SIP phones, I naively thought they were Power-over-Ethernet (IEEE 802.3af) because they were "powered over ethernet." Silly me. Polycom must have some odd voltage or funny way of injecting the power, because the POE switch I bought for them (Netgear F@510P) won't power them, though if I use the Polycom-supplied AC adapter and ethernet power

Orinoco Injectors
Has anyone gotten the Lucent / Orinoco injectors (AE-1, AE-6, AE-12) to work with the Cisco 79* series phones? I'm not sure if the are the statndard POE or not.... -Darren

htree and nfs benchmarks
Well here is what I got from testing htree with NFS. http://labs.zianet.com/benchmarks_html/postmark_benchmarks_NFS_100_htree.html It looks like htree improves performance when the storage device is local(as per my previous post) but it looks like htree degrades performance when used in conjunction with NFS. I am going to try it with gigabit ethernet when I get the time to see if maybe I am

memdisk issues with 3com cards
I'm using pxelinux in an interesting way, to load DOS boot disk images from a win2k RIS (Remote installation Service) to do various functions. Soem of the disk images are used for flashing the BIOS on pcs, but a specific few are set aside for booting MSDOS with MS lanman so that ghost can be run to load images to/from the lan. I've got 6 different disk images setup and the all work

Vlan question
There is a way to ensure traffic prioritisation...but it can work out a little expensive. 1. Use 3Com 4400 PWR as your switch. 2. Use 3Com NJ200/NJ220 (US) or NJ205/NJ225 (EU) POE Multiport switches 3. Use 3CNJVOIP-CPOD POE --> 7960 POE/Data splitters for power and data connections to the phone. The 4400 Delivers Power to the NJ2xx switches, these switches have 4 ports which can be

Which phones are good, or at least acceptable, for home and office
I am looking to replace all of the old "Bell" (POTS) phones in my home and office with IP phones. As you can imagine I don't have a huge budget to work with but I want phones that will provide acceptable voice quality and durability. There are basically three categories as I see it 1. satellite phones (low cost, low function) 2. primary domestic phone (good quality, POE capable,

ext3 2.4.21 htree tests
Hi, Just thought I'd share some test results of mine in case anyone is interested. Basically the tests are siumulating what our product does with files - although the tests do it a lot quicker (not as many files though). The test is to create 1 million files (each containing the text of the file number) spread over a number of directories. The files are then removed in the same manner as

Most decent phones have an ethernet passthrough (2 port) so you can plug in your PC. As long as your LAN is decent (Cat5 100baseT switched) the overhead using VoIP is

Using memdisk to remotely flash BIOS
I am using memdisk to remotely flash the BIOS and other firmware. It works well for most flash programs. After the flash I need to initialize the NIC to send a signal to my management server that the flash is complete. I am curious as to how others have solved this problem. Thanks.

benchmark adn threshold
Hi all, i'd like to know if there is a tool like an injector that permits to increase progressively the load onto a Samba server. My aim is to define a threshold as the number of concurrent users connected and accessing shares simultanously on a samba3 PDC. I don't care about network transfer rate. thanks for your answer

Questions about builds
I have a couple of questions about the various Icecast builds that exist: 1) It seems like new builds being done today are all "kh" builds. Is that observation correct? If I see something non-kh, is it older by definition? 2) Other than possibly age, what is the conceptual different (if any) between kh and non-kh builds? What do kh builds hope to accomplish that old Icecast never did?

Easiest defense against SQL injection in object creation?
I''ve been scouring the web for suggested Rails defenses against SQL injection, but I haven''t found much on the object creation part. Certainly using attr_protected, etc., is a good way to prevent unwanted fields from being modified on the new object (if you''re passing a hash as creation parameters), but what about escaping the POSTed info before saving? Couldn''t
