Samba4 Internal DNS Issues

[Paul Littlefield]

Hi Folks

I have successfully installed Samba 4.1.0pre1-GIT-8aae8b5 from git as a primary AD DC. This has been running fine for 2 weeks at 192.168.0.208.

I have added a secondary Samba4 from (same revision) git. It seems to have joined OK, and DNS appears to be fine at 192.168.0.209.

Primary DC = Linux samba 3.4.34-gentoo #3 SMP Wed Apr 10 13:09:37 BST 2013 x86_64 Intel(R) Pentium(R) CPU G6950 @ 2.80GHz GenuineIntel GNU/Linux

Secondary DC = Linux samba2 3.8.0-19-generic #30-Ubuntu SMP Wed May 1 16:36:13 UTC 2013 i686 i686 i686 GNU/Linux

However, a few oddities are occurring and wanted to know if this is normal?

1. There are 30+ connections for DNS port 53 at regular times:

tcp  0  0 192.168.0.209:51252  192.168.0.208:53  TIME_WAIT  -
tcp  0  0 192.168.0.209:54264  192.168.0.208:53  TIME_WAIT  -

tcp  0  0 192.168.0.209:54927  192.168.0.208:53  TIME_WAIT  -

...and then clears them up.

2. On the Secondary DC, these entries appear in log.samba:-

[2013/05/24 12:01:32,  0] ../lib/util/util_runcmd.c:317(samba_runcmd_io_handler)
   /usr/local/samba/sbin/samba_dnsupdate: ; TSIG error with server: tsig verify failure
[2013/05/24 12:01:32,  0] ../lib/util/util_runcmd.c:317(samba_runcmd_io_handler)
   /usr/local/samba/sbin/samba_dnsupdate: ; TSIG error with server: tsig verify failure

   ../source4/dsdb/repl/drepl_ridalloc.c:43: RID Manager failed RID allocation - WERR_BADFILE - extended_ret[0x0]


Can anyone tell me if this is OK or not OK?

Thanks.
