[Samba] question about zone and tsig verify failure
Hai?
?
Im running:?debian wheezy, sernet samba 4.1.3 , DC, in windows 2008 AD domain.
?
Im reading the wiki and i stumbled on this.
https://wiki.samba.org/index.php/Dns-backend_bind?
semanage fcontext -a -t named_var_run_t
/usr/local/samba/private/dns/${MYREALM}.zone
semanage fcontext -a -t named_var_run_t
/usr/local/samba/private/dns/${MYREALM}.zone.jnl
the strange thing is, and this is also my question,
Should there be the zone files, if you using bind9.
Since im not seeing these. the server ( samba 4.1.3) has joined a windows domain
as DC, no problems,
only the samba_dnsupdate --verbose --all-name give ; TSIG error with server:
tsig verify failure
all other tests are ok as far i can see.
if tested bind9 ( debian wheezy stable ) 9.8.4
and i backported bind from sid,
BIND 9.9.3-rpz2+rl.13214.22-P2-Debian-1:9.9.3.dfsg.P2-4
Both do not create these zone files.
dlopen is loaded:
Dec 19 14:50:58 ws005-s4dc-001 named[301]: generating session key for dynamic
DNS
Dec 19 14:50:58 ws005-s4dc-001 named[301]: sizing zone task pool based on 5
zones
Dec 19 14:50:58 ws005-s4dc-001 named[301]: Loading 'AD DNS Zone' using
driver dlopen
when i run : samba_upgradedns --dns-backend=BIND9_DLZ it looks ok but no zone
file.
Reading domain information
DNS accounts already exist
No zone file /var/lib/samba/private/dns/subdomain.domain.tld.zone
DNS records will be automatically created
DNS partitions already exist
dns-WS005-S4DC-001 account already exists
See /var/lib/samba/private/named.conf for an example configuration include file
for BIND
and /var/lib/samba/private/named.txt for further documentation required for
secure DNS updates
Finished upgrading DNS
i also noticed that the output of these 2 are different.
ls -lai /var/lib/samba/private/sam.ldb.d/
ls -lai /var/lib/samba/private/dns/sam.ldb.d/
after restarting bind, i noticed that
samba_upgradedns --dns-backend=BIND9_DLZ
didnt seem my bind9 upgrade, and bind is not starting anymore, manually fixing
/var/lib/samba/private/named.conf changing bind9.8 to 9.9 dlopen fixed it.
bug ? shouldnt samba follow the installed bind version?
?
After reading a lot about the tsig message, i've read there is a fix,
if the fix already applied, or do i have an other problem.
?
?
best regards,
?

I think that you only get them if you are running an earlier version of Bind with flat files. Rowland

[Samba] question about zone and tsig verify failure
Ok thank you for that info. I just got met new xen server and im testing a bit around. other question. when you run : samba_dnsupdate --verbose --all-name do you have any errors.

All other dns setups use ADS to store the zone infos. To see whether samba is using the internal DNS or ISC bind: samba-tool testparm -v --suppress-prompt | grep "server services" When "dns" is listed, the internal server is used. Btw - dnsupdate is used in both cases. Remove "dns" for the DLZ driver. (smb.conf) The [global] smb.conf option dns forwarder = ..... is also only used with the internal DNS server, bind uses it's /etc/named.conf for that. In case you want to use the DLZ driver, check the following 3 files 164962 -rw-rw---- 2 root named 4251648 Dec 19 14:44 DC=DOMAINDNSZONES,DC=ADDLZ,DC=KUKKUKK,DC=COM.ldb 164963 -rw-rw---- 2 root named 4251648 Dec 8 20:56 DC=FORESTDNSZONES,DC=ADDLZ,DC=KUKKUKK,DC=COM.ldb 164947 -rw-rw---- 2 root named 421888 Dec 19 14:44 metadata.tdb with both ls -lai /usr/local/samba/private/dns/sam.ldb.d/ (path might be different) ls -lai /usr/local/samba/private/sam.ldb.d/ (path might be different) to use the _same_ inodes. Also note that some distros run ISC bind as user "bind", others use "named". This user/group must have access to some already discussed samba files/paths .... I often use the following 2 root consoles for testing: 1.) named -g -u bind -d3 (Note that "-u bind" must be replaced with "-u named" on some distros) 2.) samba -i -M single -d3 Both programs should now run and send their debug 3 output to their consoles. When you see lines like Not authoritative for 'wiki.samba.org', forwarding in the samba log, the internal DNS is active. That output ; TSIG error with server: tsig verify failure is usually only seen when the internal DNS server is running. It's a glitch, which can be ignored atm (all dyn. updates are done OK).

Hello G?nter, Thank you very much for this explaination. This makes sence. to bad for me i just removed my server for a new install.. :-/ but good to know TSIG error is only a glitch, maybe something for the wiki ? btw.. this explaination is also good for the wiki.
