Never a good deed that goes unpunished... I just tried to run the port trafshow but when I do, it says: trafshow: BIOCSETIF: ix0: Device not configured Tcpdump also says: tcpdump: ix0: Device not configured Which surprises me because the network has been working since I installed 2.0.5 (now running 2.1-stable). Netstat -i says: Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll lp0* 1500 <Link> 0 0 0 0 0 ix0 1500 <Link>00.aa.00.36.67.74 3475 0 2529 0 0 ix0 1500 205.148.224 rigel 3475 0 2529 0 0 lo0 16384 <Link> 613 0 613 0 0 lo0 16384 your-net localhost 613 0 613 0 0 sl0* 552 <Link> 0 0 0 0 0 tun0* 1500 <Link> 0 0 0 0 0 ..and ifconfig -a says: lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500 ix0: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING> mtu 1500 inet 205.148.224.9 netmask 0xffffff00 broadcast 205.148.224.255 lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 16384 inet 127.0.0.1 netmask 0xff000000 sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552 tun0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500 ...and before I tried to use any of this, I changed the kernel to add the packet filter pseudo-device: ---- [ ... ] pseudo-device loop pseudo-device ether pseudo-device log pseudo-device sl 1 pseudo-device tun 1 pseudo-device pty 16 pseudo-device gzip # Exec gzipped a.out's pseudo-device speaker pseudo-device bpfilter 4 ---- Is this the driver's gentle way of telling me it can't be placed into promiscuous mode? (I've also tried trafshow -p) -Dave
