site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com Organization: Heeltoe Consulting (just *full* of questions today :-) I'm having trouble using ioctl(SOL_NDRVPROTO, NDRV_SETDMXSPE) on an AF_NDRV socket. I'm trying to filter for protocols 0x800 & 0x806, ip and arp. I get an error when I do the NDRV_SETDMXSPE ioctl. If I make the protocol numbers something odd, like 0x801 and 0x802, the ioctl works fine, repeatedly. I set the address family in struct ndrv_protocol_desc to a unique value (in this case 0x11223344). Any idea why? Since non-standard ethernet packet types work, I'd think I'm doing the basics correctly. Seems odd that 0x800 & 0x806 won't work, unless the demux checks and requires them to be unique. I'd rather not use BPF, but I'm wondering if that is the only good solution. I'm running 10.5.5, btw, on an x86. -brad _______________________________________________ Do not post admin requests to the list. They will be ignored.
