Hello, I''m using tc to limit the bandwidth of our wireless customers. I have a working script, but I''m not happy with it. I''m trying to write a more sophisticated script, but when I run it, it give me this error: RTNETLINK answers: File exists I have no idea what this error means or how to fix it. Here is a portion of the script (the whole script shapes several

Hi all, I''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

Hi,All I am using iproute2 to manage bandwith for ADSL router.High,medium,low priority are needed for different protocol port on the ADSL's upstream side,as following: LAN --- |ADSL Router|------WAN When there aren't traffic on the specific priority, its bandwidth should be borrowed by other priorities.But it doesn't work.Here is my script: /usr/sbin/tc qdisc del dev nas0 root

Hi all. I fear I''m slightly offtopic with this question, but I''ll keep it short: who is (or feels) responsible for the #lartc irc-channel in oftc.net? I''d appreciate if that person would get in contact with me (off-list) in order to discuss some ideas I have. Thanks in advance.

Hi All, I found 2 unusual behavior with u32 classifier in Kernel 2.4.12. I’ve u32 compiled as module. 1> u32 filter seems not working if there is already some fw filter used for some other class. In order to get u32 working I’ve to delete root class, which in terms delete all fw filters too, and then same command for u32 works. fw is also compiled as module. 2> If I add u32 filter to my

Hey all, I had asked a question a little while ago about CPU usage being outrageous while using tc and a cbq qdisc. Ed was very kind and offered a few suggestions. One of these was to look at hashing. So after pounding away at it for about a week, I have a general understanding of how it works and have tried to implement it. Unfortunately, and quite obviously since I''m posting here, it

I am using a server with asterisk and I am trying to prioritize voip traffick -- I am a newbie at this traffic shaping, so please bear with me. I used the script below and what happens is thatall traffic in the bulk class stops after a couple of minutes. Also, should I include the ports for rtp in the filter statements with the ports 5061 and 4569? Note I have a fairly big pipe -- supposed to

OK, finally I have made cbq run ! now I would like to know if it is posible to limit a range of IP to a speed. something like this : from 192.168.1.1 to 192.168.1.21 limit to 128K I don''t whant to limit each IP to 128K, what I would like to do is limit all 20 IP to have a max of 128K. Is it posible?

Hi All , My first message and I have a little problem with my FC6 box trying to block emule traffic using layer7 .

The manual says (about prio): > Because it doesn''t actually shape, the same warning as for SFQ holds: > either use it only if your physical link is really full or wrap it > inside a classful qdisc that does shape. The latter holds for almost all > cable modems and DSL devices. I want to wrap prio inside of tbf. Here''s why: I have a server on a DSL line, which has

Hello, I am using the following commands to "throttle" the bandwidth of the NIC at eth0 : tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 10: cbq bandwidth 100mbit avpkt 1000 tc qdisc add dev eth0 root handle 10: htb tc class add dev eth0 parent 10: classid 10:1 cbq bandwidth 100mbit rate 128kbit allot 1514 maxburst 20 avpkt 1000 bounded prio 3 tc class add

Hi folks. For quite a while, I tried to use linux (cbq and htb) to control bandwidth in order to replace a cisco equipment used to play this role on our network. After trying here and there, with a bunch of different distros, different versions, different compilations, ... the closest I could get was as follows: (using htb.init and cbq.init) Desired BW ==> Achieved BW 128k ==> 404.78
