I want to take the functionality that I found sitting in linux-2.6.8-rc2/net/sched/sch_netem.c for a test drive but I found that the /sbin/tc that I have does not have the necessary knobs. So I grabbed iproute2-2.6.X-ss040702.tar.gz and tried to build it, but I got this: q_netem.c: In function `netem_parse_opt'': q_netem.c:90: error: structure has no member named `rate'' and indeed, there is no longer a .rate member of the struct tc_netem_qopt. I did some web searching and the patch mentioned here seems to be responsible for removing it: http://l...

I''m trying to setup a netem delay with no luck (using iproute2-2.6.8, compilation broke during arpd compile, so I use the tc binary in the tc/ subdir, there''s also a q_netem.so there). kernel is 2.6.8.1, compile with CPU cycle counter as time reference. I was using sch_delay of 2.6.7 happily with something like: tc qdisc add dev eth0 root 1: delay latency 1ms rate 35M now I use: tc qdisc add dev eth0 root netem latency 1ms and it complain about "unknown qdisc nete...

Hi, I am using iproute2 to setup fowarding, adding routes like "ip route add 192.168.1.3 via 192.168.1.2" I was wondering where in the kernel I can insert probabilistic packet loss only for forwarded packets? So that for instance I can drop 5% of all forwarded packets? I don''t need help with the actual code, just need help finding where to insert this code :) Thanks! George

Hi , I''m trying to call the tc_qdisc_modify function of tc in iproute2/tc. I could compile it with my stub program and got the executable. However, when i try to create an htb qdisc i get the following error : Unknown qdisc "htb", hence option "default" is unparsable However, if i use the tc tool, it works fine.. When I tried to understand the problem, it appeared to

Hi, I am trying to install a proprietary qdisc made for research, it is not publically released yet, however its been used several times so i know it works. The files included are: q_xcp.c: static int xcp_parse_opt() static int xcp_print_opt() static int xcp_print_xstats() struct qdisc_util xcp_util = { "NULL", "xcp" ..... }; sch_xcp.c: static int
