If so, fix it there. No, I am trying to allow tcpdumping of all traffic travelling through the bridge at any port of the bridge, most of which are running UML virtual machines. This isn't fixing some flaw, or trying to work around features - for example it is a legitimate need to be able to set up a dumper for some part of the network. At my former workplace, we used to have a 'guaranteed hub' - an old 10Mbit hub that was guaranteed to do no MAC address learning - that we used when we needed to dump some traffic for a certain computer. And no, the bridge will not be running spanning tree protocol either. >> Or could this be done with some ebtables hack? > > Yes Instructions appreciated, then. -- Naked
