Hello, On a Sun Sparc Ultra5, where `uname -m` reports "sparc64", and the bridge kernel modules is loaded (`insmod bridge`), reports on `brctl addbr br0` with add bridge failed: Operation not supported That failure writes in /var/log/kern.log sys32_ioctl(brctl:572): Unknown cmd fd(3) cmd(000089a0) arg(effffcbd) My questions are: * Are there succesfull reported sparc64 systems doing bridging? * What should I do to get that sparc64 acting as a bridge? Cheers Geert Stappers
