Aloha, Does anyone know of any opensource or inexpensive software that can test a network for a possible VoIP installation? I have seen Chariot by NetIQ, but it is very costly! I am envisioning two or three "client" devices that talk to a server device. Each client could simulate 1-100 VoIP phone calls. The server module would monitor the QOS, jitter, etc., and provide some kind of

Is there any piece of software that I can use to run between a client and a linux or windows server with a smb/cifs share that will test network speed, latency, sustained read/writes, multiple file create, read, write, close, etc.. etc.. over X period time? I'm testing a Centos server with samba and Windows 2k3/8 servers on the other end of a T1 connection and while I know the T1 bandwidth

Tool Recommendations for measuring UDP throughput / loss / jitter Hello all, I'm looking for recommendations on getting some measurement software set up so we can work with our ISP to determine where packet loss is occurring. Linux and windows tools are fine, it's just every time I start searching on google I run into many possibilities and am not sure what I should be trying. Maybe

Dear all, I am running squid on centos 5.Is there is any tool to calculate number of ip's hit the server for month wise. Even any command to find out the number of hits is also ok. Regards, Lingu

What's the best way to do this? Daily, jpg images are added to an inhouse server. Everynight I want to backup these images to a server offsite, via rsync. What I want is to determine what to set the bwlimit to. I also want to estimate how many MB's of images I can move nightly. Thanks Dan

Hello, i am searching for a method to generate traffic and measure it, to compare several version of tc configurations. For my thesis i am researching the best way to use tc for medium sized companies. For this purpose i analyzed the company network and created a tc schema. Now i have to test this definition in a kind of simulation outside the network. Also i have to do a comparison of the

I am trying to trouble shoot one of my ISP's network and compare to my other ISPs offering. Although network 1 is reasonably fast and has low enough latency, voice quality is not good and the reason for this is not readily apparent using standard network tools. What tools can be used to assess the quality of the network in terms of it's suitability for voice? I am using ping, mtr,

...IC, 2x Western Digital WD200JB RAID 0) to my Windows-PC(AMD Athlon XP 1800+, 1024 MB DDR-RAM, WINXP PRO, RTL8169 NIC, 2x Western Digital WD080JB RAID 0) with Samba, i get Speeds around 8-9MB/sec. I think this is too low for an GBit Network, so i tested the NIC's with the Tool Iperf (http://dast.nlanr.net/Projects/Iperf/) and the throughput with this tool is 300 Mbit/sec, so I think, i can get 20 MB/sec with Samba. The Bottleneck why its only 300 Mbit is the "old" File-Server Hardware. I'm using CAT 6 Cables and a 8-Port GBit Switch. The Cards are running both at GBit speeds, as th...

Greetings list, Hoping someone might have experience with poorly-performing net connections and which devices work best over them. One of our clients has a number of employees that work from home, and are given a SIP phone to take with them and hook up to their broadband. For the most part, this works fine, but there are an increasing number where sound quality is poor ("chops" in and

Hi there! I am working a lot with VoIP in my company, so I thought to use linux bridge functionality together with tc to emulate delay, jitter, packet loss, duplication, reordering etc. for testing purposes in our lab against our VoIP products. I just recognized, that a basic bridge just with it''s minumum configuration of 2 network interfaces creates latency of approx. 5ms on very low
