The place to change HYSTERESIS is /usr/src/linux-2.4.32/net/sched/sch_htb.c No, it is not quite that simple. You should experiment with HYSTERESIS to see what works best. For ATM, I recommend 0. Use an editor to change the kernel source. Make sure you have a working .config in the source tree (that can be the hard part, but your distro should provide the .config that matches your kernel). Get into the source tree: cd /usr/src/linux (if there is a symlink) or cd /usr/src/linux-2.4.32 rm .version make oldconfig Check .config to be sure it looks like what you want. The syntax of the following is a personal preference: make dep ; make clean ; make bzImage Check to be sure the kernel built properly. make modules ; make modules_install Install your new kernel. Run your boot loader (lilo / grub / ??). modprobe sch_htb lsmod If all is OK, you don't need to reboot. Otherwise fix anything that a reboot won't fix and reboot. -- gypsy _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
