Hello all i have what is to me a very strange bind 9 master slave transfer issue.
When i update a zone file on the master the file updates correctly the notifies are sent and every thing seems to work perfectly except it transfers 0 bytes to the slave. Checking the slave confirms that indeed thier was no transfer and that the slave is still serving the old zone, i have gon as far as to completely delete the zone files from the slave and restart bind to my suprise it puts back all the old files. What is going on? Below is an example of one of the files that is not updating correctly there are many and some of file I have updated more recently are not even showing up in the logs of the server.
On the server Ubuntu 8.04 LTS running BIND 9.4.2-P2.1 chrooted
29-Mar-2012 06:03:39.461 general: info: zone jodygamracy.com/IN/external: loaded serial 2012031501
29-Mar-2012 06:03:39.614 notify: info: zone jodygamracy.com/IN/external: sending notifies (serial 2012031501)
29-Mar-2012 06:03:41.761 xfer-out: info: client 22.214.171.124#33074: view external: transfer of 'jodygamracy.com/IN': IXFR ended
On the slave Ubuntu 10.04 LTS BIND 9.7.0-P1
29-Mar-2012 00:03:41.666 general: info: zone jodygamracy.com/IN/external: Transfer started.
29-Mar-2012 00:03:41.706 xfer-in: info: transfer of 'jodygamracy.com/IN/external' from 126.96.36.199#53: connected using 188.8.131.52#33074
29-Mar-2012 00:03:41.782 xfer-in: info: transfer of 'jodygamracy.com/IN/external' from 184.108.40.206#53: Transfer completed: 0 messages, 1 records, 0 bytes, 0.076 secs (0 bytes/sec)
As a side not i have both machines firewalled, but have port 53 open on both machines, and have ports set using this in these lines in the named.conf. file
query-source address * port 53;
transfer-source * port 53;
notify-source * port 53;
and see this in the dameon logs
/etc/named.conf:9: using specific query-source port suppresses port randomization and can be insecure.
