Just a quick note for those reading this on the list, version 1.X up to, and including, 1.0.3 doesn't work on 2.4 kernels, Stephen is looking at that and there should be a new version :-) > when i type ./configure then make then make install to bridge-utils-1.0.3, > but u come out with error said lsysfs cannot found? Yes, by default new versions of the tools require libsysfs, you'll have to specify a parameter to configure to build without libsysfs. > But when i install bridge-utils-0.9.6, it succeedful install but nothing > come out, i type lsmod, i did not see any brctl brctl is a tool to control the bridge, not a kernel module, thus it cannot be seen on lsmod, but if it installed well you can surelly run brctl and get its help or do a man brctl, ... BTW: there are bridge-utils packages on most distros out there, maybe you should install the binary package that comes with your distribution. Regards... -- Manty/BestiaTester -> http://manty.net
