Hello, I have wrote some scripts to shape about 1000 workstations. My config: Pentium IV - 2GHz, 1Gb RAM, RedHat Enterprise Advanced Server 3, kernel 2.4.21-9.EL, iproute-2.4.7-11.30E.1 2 Gigabit Lan cards in bridge mode. I use htb. Everything work fine, but I have troubles with showing running configuration. # Init shaper root for dev eth0 tc qdisc add dev eth0 root handle 2: htb default 200

Hello, I use HTB with linux-2.4.20-ac1 and iptables-1.2.7a (pathced for IMQ). I configured one HTB qdisc on an IMQ device. This qdisc has some classes (about 5) and all of the classes has qdisc pfifo. I sometimes got out from my linux (while I was working) and I found in logs: Dec 4 11:49:27 core kernel: HTB init, kernel part version 3.7 Dec 4 11:49:28 core kernel: HTB: quantum of class

Hello. I''m running linux box with Slackware 9.1 and compiled kernel 2.4.31 with "yes" to VLANs and "yes" to all QoS. On this box i have more ethernet interfaces: eth0 eth1 eth2 and so as more vlan interfaces: eth0.100 eth1.3 eth1.4 This is entrace(uplink) router to our whole network and my goal is to shape users on this machine. I want for this purpose use HTB so

I need to shape traffic from some IP on one LAN, but I''m in trouble. There is a linux 2.4.26 connected to the Internet (eth0) / LAN(eth1) doing NAT. I''m using VLANs in the LAN Interface, that is connected to a 3Com SuperStack II in a 802.1Q tagged port. I want to create a class that will limit the traffic at 384Kbit/s. I want to create two leaf classes that limit the traffic at

Hi all. I''ve written a small htb script that uses U32 and FW (marked by IPTABLES) filters, but TC doesn''t seem to be using the "cls_fw.o" module !!! I''m using redhat v9.0, kernel 2.4.8-20, iproute 2.4.7-7. Here is my script: ========================================================== ##################### #Interface definition #####################

I''ve done some tests with TC FILTER and his PRIO and think that is an error or OMISION on TC FILTER DOCUMENTATION from: http://lartc.org/howto/lartc.qdisc.filters.html#AEN1100 Let''s say we have a PRIO qdisc called ''10:'' which contains three classes, and we want to assign all traffic from and to port 22 to the highest priority band, the filters would be:

Hi, I am currently working on the TC. I have seen some behaviour which seems to be odd. I know someone in the mailing list would have seen this problem or may have some fix for this problem. When I try to include u32 filters with different priority or pref, I could see the filters being set on all the priority''s irrespective of the priority number. See my sample script below and the

Hi, I am currently using TC for setting up user MAC based filters,and I am seeing a problem when I try to assign different priorities to the MAC Match filter apart from the root qdisc and parent class. Here is my script. /*****************************************************/ First of all I create the qdisc and class based on priority 2 and also the Hash mask tc qdisc add dev eth1 root handle

I shape my upstream cable link with HTB from a script. My voip traffic (from the 192.168.0.14 host) gets priority over everything else to the near-starvation of other classes; the rest of the traffic is split up based on some priority rules (qos, empty ack packets, etc). eth1 is the uplink I''ve been using HTB and fw marking for the job until recently, when I changed the queue structure

Hello, I''m trying to shape traffic by IP addresses and by 802.1q vlans. But when I add 802.1q filter filters output looks strange. Maybe I''m missing some options to TC? Thanks, Mindaugas # ./bin/tc -s -d filter show dev eth0 filter parent 1: protocol ip pref 1 u32 filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 1 u32 fh

Hi to everybody I''m trying to use PRIO qdisc to prioritize the traffic but i have strange problem maybe I''m missing sometging. First i add root qdisc like this tc qdisc add dev eth0 root handle 1: prio it''s fine after this i try to match traffic by tos field but i get error invalid match tc filter add dev eth0 parent 1:0 prio 1 protocol ip u32 \ match ip tos 0x10 0xff

The interface is setup like this: # tc qdisc del dev eth0 root # tc qdisc add dev eth0 root handle 1: htb default 2 # tc class add dev eth0 parent 1: classid 1:2 htb rate 20mbit ceil 20mbit If I add a second class and a filter to send traffic to it like this: # tc class add dev eth0 parent 1: classid 1:130 htb rate 1Mbit ceil 1Mbit # tc filter add dev eth0 protocol ip parent 1:0 prio 130 u32

Sorry for all the questions I''m just trying to understand how it all works. Thank you for your time. Is the following configuration possible? where ht 800 links to 3: for the 3rd Octet in the IP and then 3: links to 4: for the fourth Octet? tc filter add dev eth0 parent 1:0 prio 10 handle 3: protocol ip u32 divisor 256 tc filter add dev eth0 protocol ip parent 1:0 prio 10 u32 ht 800::

Hi, I am trying to write a script that will create a class and will add specific Ip address to that class. let me write commands: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1 classid 1:1 htb rate 10mbit ceil 10mbit tc qdisc add dev eth0 parent 1:1 sfq tc class add dev eth0 parent 1:1 classid 1:21 htb rate 128kbit ceil 128kbit tc

Hi all! :) I see that this is partially covered in the mailing list archive but at the moment I can''t find a straight & working answer. I have an imq device with dynamically attacched classes/qdiscs/filters. There is a hashing filter that maps the last octet of an user''s IP address to a class (and associated qdisc). The "empty" filter looks like this: filter

Hello all, I am having some trouble getting a firewall filter to work with TC. I am actually setting the mark via EBTables (which is working as far as I can tell, I am also logging the packet and my syslog reports lots of marks): ebtables -t broute -A BROUTING -p ipv4 -i eth1 -s 08:00:46:60:B3:57 -j mark --set-mark 7 --mark-target CONTINUE --log --log-level debug --log-prefix "EBFW Mark

Hello, I try to add a U32 source port filter with libnl. My filter can be succesfully added with the library (no error occured) but the filter is not active. If I run "tc filter show dev eth0" I get: filter parent 1: protocol ip pref 100 u32 filter parent 1: protocol ip pref 100 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 100 u32 fh 800::800 order 2048 key ht 800 bkt 0

Hi How can I control which filter a packet will meet first? I have tried changing the order of applying the tc filter scripts and switching flowid number, but ''protocol ip u32 match ip src <ip net> match ip src 0.0.0.0/0'' always kicks in first? >From my script -------------------- # All traffic - Priority: Low tc filter add dev eth0 parent 1:0 prio 2 protocol ip u32

Dear All I am trying a very simple set up: (a bit long message follows) #Flush previous definitions $TC qdisc del dev $VVNET root >&/dev/null $TC qdisc del dev $INTERNET root >&/dev/null $IPT -t mangle -D PREROUTING -i $INTERNET -d 200.231.56.0/24 -j IMQ --todev 0 # Mothers off all disciplines $TC qdisc add dev $VVNET root handle 1: htb default FFFF r2q 1 $TC qdisc add dev

Hi everyone, My HTB script is showing me those "r2q change" warnings. I read that I should test with r2q values to gain accuracy and stop the warnings but I made some tests with r2q and with burst and I still get the warnings. Any ideas on this issue will be very helpful. The script seems to be working as the bandwidth for the IPs is being shaped. The NIC works at 100mbit and the
