This makes sense... > but rather that it was (correctly) delivering > non-promiscuously uml_switch is broadcasting, the uml driver is doing the filtering (so the network stack doesn't see unwanted stuff). > -- meaning I didn't have to trick my protocol software > into filtering out the unwanted packets using the "ifconfig promisc" > approach that was required with "ethX=mcast". This part of your mail doesn't make sense _to me_, you're either missing or adding some negations. If things are correct eth0=anything gives the same result: non-promiscous by default and promiscous only if you ask (with "ifconfig promisc" or by default by packet sniffers); the only difference is that some trasports are "broadcast" (like Ethernet with hubs) and others not (like Ethernet with switches, even if technically this is still referred to as a broadcast LAN since you can do broadcast). Sorry, didn't you complain that promiscous mode wasn't auto-enabled by "eth0=mcast"? Ok, you expected that your software had to cope with this situation and not coping with it is better, but there's still somebody not playing within the rules. Maybe it's all ok, but could you rewrite the above paragraph to make it clearer for me? You've flipped some sentences... since "promiscuos" means "the interface accepts every packet" and non-promiscous means "the driver or the hardware only accepts packet with the right destination MAC". > In short, I think everything is now working as it should.
