[Samba] netbios uses incorrect broadcast value and termintaes
Hi All,
I am using samba Version 3.5.4 on AIX 6.1.
The installation is through pware binary ( pware53.samba.rte 3.5.4.0).
There seems to be a strange issue with NetBios where it terminates with the
following error logged just after starting.
The diagnosis fails in step 4 of Samba Diagnosis test ("nmblookup -B
BIGSERVER __SAMBA_") because no netbios (nmbd) is running.
snippet from nmbd logs:
[2010/08/18 08:42:17, 0] nmbd/nmbd.c:857(main)
nmbd version 3.5.4 started.

Is there any possibility of bad RAM or a bit flipped by a cosmic ray in your disk cache or something? :) -- Michael Wood <esiotrot at gmail.com>
