...s tcp connection (not packets)? something like this: src_IP dst_Ip, srcPort, dst_port bytes_send bytes_received? Any netfilter extension? 2 issue: eth0------- connection 1 NET ---------gw (linux) eth1--------connection 2 Real bandwitch on connection 1 and connection 2 is depend on different things (ie weather) How to detect that connection 1 is loosing i.e. 50% packet (or real bandwitch is less than ...) and based on this change routing? Thanks for ANY help. Pawel Z ----------------------------------------------------...

Hi guys , I'm writing in the mailing list for asking if tou know some script or system linke Mrtg for see the bandwitch usage of every mountpoin. Thanks Pierpaolo Gull?

Hi, machine: AMD K6 200 MHz Linux distribution: Mandrake 8.1 kernel: compiled 2.4.21 applied this: #define PSCHED_CLOCK_SOURCE PSCHED_CPU in file linux/include/net/pkt_sched.h bevore compiled the kernel (described on http://www.docum.org/stef.coene/qos/faq/cache/40.html) bandwitch on eth0: 128kbit The most simple configuration - 122kbit guaranted for WWW (sport 80) and 6kbit for the rest. tc qdisc del root dev eth0 tc qdisc add dev eth0 root handle 1:0 htb default 3 tc class add dev eth0 parent 1:0 classid 1:1 htb rate 128kbit ceil 128kbit tc class add dev eth0 parent...

Hi, good people! I wanted to limit my 4 customers to 144, 16, 32, and 32kbps. I used the following tc commands BUT IT FAILED TO LIMIT each and everyone of them to its bandwidth. What am I doing wrong: My tc scripts are: tc qdisc add dev eth1 root handle 1: htb default 1 #Classes# tc class add dev eth1 parent 1: classid 1:1 htb rate 9bps ceil 9bps #Default

...fishworks 2010.Q3.2.0. The purpose of the system is to proveide NFSv3 shares for our mini-cloud The system is mission critical. Our problem is, that both devices experience low performace, and high latency (up to 1.5sec on some operations) due to heavy cacheing the main storage-s full input+output bandwitch is about 5MB/sec with ~2000 op/sec from NFSv3 (1950 metadata cache hit/sec, 350 data hit/sec 50 data miss/sec) The very strange thing is: we have very high rates at disc percent of utilization (every disc) due to ~3200 iops in the discs (60 iops / data disc) with 0 size if we initiate a sequencia...

Hi ! Anyone can show me a script for bandwitch management to contain packets marking with iptables and tc filters? For example, I want to set limits for 192.168.10.0/24 class: international min 64 kbps max 128 kbps; metropolitan 192.168.10.0/24 and 192.168.11.0/24 classes with 100 mbps management between them. Respectfully, Daniel Phlande...

...much bandwidth you used. To save you the headache of worrying about those calculations consider sending a 49 byte packet. It will clearly need to be split into two 48 byte packets (yes?), then each packet has a 5 byte header = 53 bytes each, so that 49 byte packet takes up 53*2 = 106 bytes of bandwitch on your ATM line. On the other hand if you used really large IP packets then the overhead would be less, consider the effect of a wasted 53 byte packet when you are sending in chunks of 1500 bytes a time. So big FTP transfers with large IP packets don''t waste too much, but if you hav...

Hey list I have almost gotten my shaping setup up and running as planned. The last barrier seems to be tcp overshooting availible bandwidth when its starting a transfer, and thereby bursting the line, so ping rises for a moment. At least this is my best guess at the problem :) There is a possibility that its just plain old traffic being bursty for some reason.. I am using bittorrent to test this,

Hello, We have a box with good connectivity which we divide among several internal networks by having a different interface for each internal network and rate limiting outgoing traffic on each of these interfaces. We are using cbq and a u32 match on the destination to organize the packets. This works very well for us, but there may be a better way, I''m no expert at this! We also use a

...pace, up for 4 days. I'm not very xperienced in tunning the memmory system nor the swap system, help appreciated to avoid this memory 'trashing' situtation (14 virtual desktops openned at the same time). Is it a normal situation? Is it a correct protecction measure? It's due a low bandwitch IDE HD? how can i tune it to avoid this situations? is it a high load for this workstation? I think the oom-killer was called correctly to avoid the system collapsed, but i think there was a problem in the swapping subsystem or a memmory trashing situation to avoid. Help and hints appreciated, At...
