I think I found the source code that generates these error messages in /usr/src/lib/libalias/alias_nbt.c In general, libalias appears to be a collection of routines to handle aliasing of TCP/IP packets (i.e. translating between your local IP numbers and the public number that your gateway uses to send them out on the Internet -- if I understand it correctly). I predict that if you disable aliasing on tun0 (the ppp connection) you will stop seeing those error messages. Of course, that's not real helpful as a long term solution, but it would tend to confirm that this is the source of the messages. The particular routine in question handles netbios packets. If you aren't doing anything that requires netbios (Windows networking through your gateway), you might be able to safely ignore the messages, but when I saw them in my system things were definitely unstable. The code is rather inscrutable to someone who doesn't know the netbios protocol, so the best guess I have is that it means just what it says: for some reason, a Windows system on your network is sending a netbios query that the aliasing code doesn't recognize, and doesn't know how to handle. Of course, if you don't have a Windows system on your network, it gets even more mysterious. And I thought it was simply a matter of copying packets from one interface to another. Silly me. I hope that's helpful. Does this sound accurate to anyone? -- Bob +-------------------------------------------------------- | Bob Johnson | bobj@cisi.com +-------------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
