Hello!
I run my script, then check the results. Pieces of output:

1. Why do I have negative number of tokens in some classes, especially
1:1 ? I don''t think it should be possible.
2. Probably connected to question 1, having rate=ceil=50kbit why can I
still download stuff at rate ~10Kbyte/s?
3. Same parameters as above, downloads go at rate ~10Kbyte/s:
root@arthur:/etc/init.d# tc -s -d qdisc show dev imq0
qdisc htb 1: r2q 1 default 1015 direct_packets_stat 9 ver 3.13
Sent 1698356 bytes 4852 pkts (dropped 40, overlimits 7224)
backlog 61p
In general something is very wrong here. I''m unable to limit traffic to
become bottleneck and be able to shape traffic.
Can anyone tell me why?
(If output isn''t enough I can send my script which is quite big,
~14Kbytes)

Why do I have negative number of tokens in some classes, especially > 1:1 ? I don''t think it should be possible.Why not? Class 1:1 has child classes. These child classes are able to send pckets as long as they have tokens. Even if the parent has no tokens left, they still can send packets as long as they have tokens. So they can drag the parent tokens negative. But I don''t understand why class 1:1023 has negative tokens? Is this is a leaf class ?> 2.

I recomiled my kernel and they are again negative. Maybe it''s something about my kernel? I did some patching: kernel 2.4.22 + grsecurity 1.9.12 + patch-o-matic 20030912 (quite lot''s of patches) with htb20030625 patch + imq for 2.4.21 + imqnat + layer7 0.4.1a iproute2 with layer7 + htb

But I just realised that the tokens can be negative. And it''s not because a problem that the tokens are negative.> > > (If output isn''t enough I can send my script which is quite big, > > > ~14Kbytes) > > > > Can you send us only the tc class/qdisc commands ? > > Sure: > > <script> > tc qdisc del dev imq0 root > modprobe imq > ip link set imq0 up > tc qdisc add dev imq0 root handle 1 htb default 1015 r2q 1 > tc class add dev imq0 parent 1:0 classid 1:1 htb rate 50kbit ceil 50kbit > tc class add dev imq0 parent 1:1 classid 1:1010 htb rate 7kbit ceil > 50kbit prio 3 > tc class add dev imq0 parent 1:1 classid 1:1020 htb rate 7kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1 classid 1:1030 htb rate 7kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1 classid 1:1040 htb rate 7kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1 classid 1:1050 htb rate 7kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1 classid 1:1060 htb rate 7kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1 classid 1:1070 htb rate 7kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1010 classid 1:1011 htb rate 3kbit ceil > 50kbit prio 1 > tc class add dev imq0 parent 1:1010 classid 1:1012 htb rate 3kbit ceil > 50kbit prio 2 > tc class add dev imq0 parent 1:1010 classid 1:1013 htb rate 2kbit ceil > 50kbit prio 3 > tc class add dev imq0 parent 1:1010 classid 1:1014 htb rate 1kbit ceil > 50kbit prio 4 > tc class add dev imq0 parent 1:1010 classid 1:1015 htb rate 1kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1020 classid 1:1021 htb rate 3kbit ceil > 50kbit prio 1 > tc class add dev imq0 parent 1:1020 classid 1:1022 htb rate 3kbit ceil > 50kbit prio 2 > tc class add dev imq0 parent 1:1020 classid 1:1023 htb rate 2kbit ceil > 50kbit prio 3 > tc class add dev imq0 parent 1:1020 classid 1:1024 htb rate 1kbit ceil > 50kbit prio 4 > tc class add dev imq0 parent 1:1020 classid 1:1025 htb rate 1kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1030 classid 1:1031 htb rate 3kbit ceil > 50kbit prio 1 > tc class add dev imq0 parent 1:1030 classid 1:1032 htb rate 3kbit ceil > 50kbit prio 2 > tc class add dev imq0 parent 1:1030 classid 1:1033 htb rate 2kbit ceil > 50kbit prio 3 > tc class add dev imq0 parent 1:1030 classid 1:1034 htb rate 1kbit ceil > 50kbit prio 4 > tc class add dev imq0 parent 1:1030 classid 1:1035 htb rate 1kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1040 classid 1:1041 htb rate 3kbit ceil > 50kbit prio 1 > tc class add dev imq0 parent 1:1040 classid 1:1042 htb rate 3kbit ceil > 50kbit prio 2 > tc class add dev imq0 parent 1:1040 classid 1:1043 htb rate 2kbit ceil > 50kbit prio 3 > tc class add dev imq0 parent 1:1040 classid 1:1044 htb rate 1kbit ceil > 50kbit prio 4 > tc class add dev imq0 parent 1:1040 classid 1:1045 htb rate 1kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1050 classid 1:1051 htb rate 3kbit ceil > 50kbit prio 1 > tc class add dev imq0 parent 1:1050 classid 1:1052 htb rate 3kbit ceil > 50kbit prio 2 > tc class add dev imq0 parent 1:1050 classid 1:1053 htb rate 2kbit ceil > 50kbit prio 3 > tc class add dev imq0 parent 1:1050 classid 1:1054 htb rate 1kbit ceil > 50kbit prio 4 > tc class add dev imq0 parent 1:1050 classid 1:1055 htb rate 1kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1060 classid 1:1061 htb rate 3kbit ceil > 50kbit prio 1 > tc class add dev imq0 parent 1:1060 classid 1:1062 htb rate 3kbit ceil > 50kbit prio 2 > tc class add dev imq0 parent 1:1060 classid 1:1063 htb rate 2kbit ceil > 50kbit prio 3 > tc class add dev imq0 parent 1:1060 classid 1:1064 htb rate 1kbit ceil > 50kbit prio 4 > tc class add dev imq0 parent 1:1060 classid 1:1065 htb rate 1kbit ceil > 50kbit prio 5 > tc class add dev imq0 parent 1:1070 classid 1:1071 htb rate 3kbit ceil > 50kbit prio 1 > tc class add dev imq0 parent 1:1070 classid 1:1072 htb rate 3kbit ceil > 50kbit prio 2 > tc class add dev imq0 parent 1:1070 classid 1:1073 htb rate 2kbit ceil > 50kbit prio 3 > tc class add dev imq0 parent 1:1070 classid 1:1074 htb rate 1kbit ceil > 50kbit prio 4 > tc class add dev imq0 parent 1:1070 classid 1:1075 htb rate 1kbit ceil > 50kbit prio 5Your commands are looking fine. However, the rate parameters are too small. You probably get some htb errors in your kernel log about quantum.
