And the final thing Well if your net is ipx 802.3 only you should not see any IPX packets. Maybe you/they are running a mixture? If you want to make sure, you can use tcpdump to have a look at the packets. Ethernet_II packets have 0x8137 in bytes 12 and 13 (start counting at 0), while 802.3 have the length of the packet in there. The patch that I posted isn't in FreeBSD because I'm not happy with it. While it does work, it forces you to have the same type of IPX framing on all the interfaces of your machine. If you want to use it, you can probably find it in the mail archives or ask me and I'll send it to you. > is that when I configure the two interfaces, they both appear to have > the same host portion of the address: > > ... > > bash-2.00$ ifconfig ep1 ipx 0xb003 > lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500 > ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 > inet 194.207.51.241 netmask 0xffffff00 broadcast 194.207.78.255 > ipx 1234H.a024763b19 > ether 00:a0:24:76:3b:19 > ep1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 > ipx b003.a024763b19 > ether 00:60:08:09:13:6d > lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 > inet 127.0.0.1 netmask 0xff000000 > This looks like you are using "old" code probably FreeBSD 2.2.2 or older? You should really upgrade to the latest stuff in FreeBSD 2.2-STABLE. A lot of things in IPX was fixed, including this reuse of the host portion of the IPX address. -- John Hay -- John.Hay@mikom.csir.co.za
