Under sparc64, with the bridge module loaded, running brctl addbr br0 results in: add bridge failed: Operation not supported sys32_ioctl(brctl:6667): Unknown cmd fd(3) cmd(000089a0) arg(effffbf9) This was a known problem to the debian sparc list, and someone offered a work-around back in April to an older version of bridge-utils (0.9.6), you can see that thread here: http://lists.debian.org/debian-sparc/2004/04/msg00077.html Looking at the changelog for the bridgeutils upstream, it appears as if there have been some attempts to fix this, but it doesn't seem to work. I tried to do the "hack" that is suggested in that thread, which is impossible in the newest source, so I used the 0.9.6 source. That did indeed allow me to brctl addbr br0, but if I tried to do anything else, brctl did not know of any bridges (brctl show showed nothing, although the interface existed). ugh... thanks for any help (please cc me on any replies), micah
