Hello there, : I want to use the dsmark, but it always says: "unkown qdisc", although I : have enabled it (y in Network options), and I have my kernel recompiled. Not only must the kernel support diffserv/dsmark, but so must your iproute2 distribution. : I am using SuSE 8.1, 2.4.20 Kernel, tc available at the HTB site (with : already precompiled HTB queue). Try recompiling iproute2 after setting TC_CONFIG_DIFFSERV=y. If you like RPMs, you can always try building my RPM (written for RH, not SuSE). http://linux-ip.net/traffic-control/iproute-2.4.7-7.src.rpm * -Martin * Note, this includes the HTB patch for tc as well as compiling with diffserv support. There is no warranty express or implied. -- Martin A. Brown --- SecurePipe, Inc. --- mabrown@xxxxxxxxxxxxxx
