Thanks Chris for your hint, which triggered me to take a look at the VDE project on Sourceforge. Before posting, I was actually reading the documentation WIki of Virtual Square (V^2) at http://wiki.virtualsquare.org . Currently, V^2 and VDE look to me like a very much more comprehensive and complex project. Still, I am unsure about how much of the VDE code is actually specific to (qemu under) Linux. What I am after with vwire is only a tiny subset of that. At the moment, I study the source of vether(4) and try to derive a simple cross-over vwire pseudo-device from it to start with. Which, of course, would be redundant and simply could be eliminated by bridging all interfaces in a single bridge, unless the capability of this simple wire is augmented by channel simulation/emulation features. Then the vwire can link several bridges which run on the same OpenBSD host and 'distort' transmissions between those bridges at Link level (layer-2), for example introduce bit errors, cause bit & frame loss, insert delay, etc. Regards, Rolf
