Hello, I hava linux box with two NICs (eth0 and eth1), setup as a bridge. Thbridg(br0) sits between a server machine and a client machine. Thserver machinis connected to eth0. Thclienmachine is connected to eth1. I wanto apply a combination of neterules and tbf traffic shaping rules to eth0 and eth1 (identical rules for each NIC), so thaforward and reverstraffic arsubjected to same network conditions. Thrules written individually aras follows: tc qdisc add dev eth0 roonetedelay 164ms 30ms distribution normal tc qdisc add dev eth0 rootbf rat4017.52kbit latency 0.00477ms burst 4352 tc qdisc add dev eth1 roonetedelay 164ms 30ms distribution normal tc qdisc add dev eth1 rootbf rat4017.52kbit latency 0.00477ms burst 4352 Buobviously thabove commands are not accepted, and I would like some guidancon how to apply thesrules.

I'd likto seup a Netem box between two routers. All routing betweerouters should keep being dynamic, my questions are: - If possible, how to seup OSPF on my Neterouter? - CaNetefunctionalities be deployed directly on a Cisco router? I mean: let's imaginthaI have a link between routers A and B, I could possibly chargNetemodule on router A and then decide, for instance, to delay all packets going ouof thinterface towards router B. Could someonindicatme what is feasible and give me some guidelines ? Thanks iadvance, Vincent.

And then, connecthethernet "outside" interfaces of your routers to this "switch". Ithis case, thnetem machine does not participatin thospf proccess. If this scenario does noacomplish your needs, then you can maka layer3 router simply enabling ip forwarding ithnetem machine and using somsoftwar(like the well known GPL quaga routing suite) to implementhospf protocol in your netem router.

You will find thuser level commands into thiproute2 package (iproute2/tc/q_netem.c) which versiofits your kernel version. http://snafu.freedom.org/linux2.2/iproute-notes.html http://developer.osdl.org/dev/iproute2/download/ You will find thkernel modulof netem in the linux sources i.e. /usr/src/linux/net/sched/sch_netem.c Note: I havmada netem patch two weeks ago (at both user and kernel levels). I added a deterministic drop feature. Ialready works on Red HaES4 (2.6.9) and Red HaFC4 (2.6.11). I will port this patch to last kernel versioand then contributto the netem community.
