Weird packets

[Jochen Wiedmann]

Hello,

I have a weird problem with ISDN dialups, that I´d like to prevent.
>From time to time (between 2 and 10 minutes) my machine does an
unexpected
dialup when I use dial-on-demand. To search for reasons I do a "tcpdump
-iln
ippp0" and find packets like the following:

 03:40:37.067866 truncated-ip - 7971 bytes missing!0.243.15.104 >
         0.0.64.17: (frag 8240:8204 at 53672+) [tos 0x3a]
  03:40:37.067866 0.240.15.105 > 0.0.64.17: (frag 0:-24 at 26584) [tos 0x8]

They seem to come out of Samba, as the dialup doesn´t happen after
shutting
down Samba. However, I don´t have the slightest idea what the above
output
can mean.

Any ideas?


Thanks,

Jochen
