[Pdns-users] problems with superslave pdns

[Eugene Pefti]

Hi Anton,

PDNS forum seems to be not very active whenever one asks for help. Moreover there's a tendency to criticize people's questions not directly related to pdns such as the front-end to it. 
Getting back to your question I can share my setup but it is not exactly like yours. I have MySQL backend and two servers configured to be master and slave. Having setup MySQL Master-to-Slave replication I have all changes introduced to the master via pdnsadmin replicate immediately to the slave, namely its database. 
I don't think the replication between pgsql differs in terms of setup. I don't have much of experience with Postgresql so my suggestion is to switch to MySQL as it is more tested and often used. By the way I didn't have any problems with MySQL replication for two boxes located far from each other.

Subject: [Pdns-users] problems with superslave pdns

Hi there group,
I've setuped a superslave pdns server that should fetch automatically 
the newly added domains but nohting happens.

my master is 217.75.141.6 and the slave dns is ns1.hostit.bg.
I have this record for supermaster:
sqlite> select * from supermasters;
217.75.141.6|ns1.hostit.bg|internal

I've added a new domain into the master but it never showed up in the 
logs or in the sqlite db.
how can I debug why this happens?
there is another problem,..
I've inserted all the domains that were in the master pdns in the 
records table, when I've first started the pdns it refreshed all the 
domains,
but after that from time to time I get:
Feb 18 16:07:33 ns1 pdns[87710]: Domain interiorcity.net is fresh
Feb 18 16:07:35 ns1 pdns[87710]: Error trying to retrieve/refresh 
'voigt-bg.com': Timeout waiting for answer from 217.75.141.6
Feb 18 16:07:35 ns1 pdns[87710]: Domain arthotel-sbh.com is fresh
Feb 18 16:07:35 ns1 pdns[87710]: Domain virtualboss.org is fresh

Feb 18 16:07:39 ns1 pdns[87710]: Domain 101dalmatinci.com is fresh

I'm running powerdns-2.9.21 on both places, the os is freebsd.
on the master side it's using pgsql backend on the slave it's psql 
because the conectivity between the machines is not so good so I can 
setup pgsql replication,
and the second machine is  a vm with 1 purpose - slave dns.

thanks in advance for the advices/ideas.

cheers,
valqk.
