Im using centos 4.5 and bind 9.2.4-27.0.1.el4, im having a problem propagating updates on domains. when i update the main NS the secondary and tertiary doesn't update automatically. i need to delete the <domain>.zone file in the secondary and tertiary to get update from the main NS. I don't where's the problem i don't get any errors i just dont get the AXFR when the don't delete the file from the backup NS. -------------- next part -------------- An HTML attachment was scrubbed...

BUT ... are you increasing the serial number when you change the primary zone file? -------------- next part -------------- A non-text attachment was scrubbed...

As previously noted, you have to increase the serial number of the zone, plus in the secondary, in the conf file, you have to make sure that the ownership and permissions are correct. Ip source of the update matters too Overall, Dns is easy to debug in the log files. :-) - rh -------------- next part -------------- An HTML attachment was scrubbed...

Addtitionally, on the master you may want to add "notify yes;" to the zone stubs. This will make sure bind sends out a message (notification) to the slaves when a zone is changed.> As previously noted, you have to increase the serial number of the zone, > plus in the secondary, in the conf file, you have to make sure that the > ownership and permissions are correct.Permissions - good point. Modifying slave serials??? Er, no. Don't do that. I'm pretty sure you weren't suggesting the OP do that....but that's how it reads[1] :)> Ip source of the update matters tooUsually only a problem when you have a firewall that's matching the source IP of TCP/53 connections (zone transfers always happen over TCP). But seeing as the OP can refresh the zones after hosing the slave's cache, I doubt this is a network problem.> Overall, Dns is easy to debug in the log files?Here, here :) -- James [1] Although this morning the flu meds are doing phunky things to my brain :P Wheeeeee!
