Hello list, We currently running two instances of bind9, each one on a different host. Both hosts have their own IP address and basic tests work perfectly: - ping of external server(s) work fine (FQDN and IP address) - host resolution works fine - named processes number is quite low (~16)
The problem occurs when we try to move IP address from master server to slave server: - ping of external server(s) failed (FQDN and IP address) - host resolution take a huge time to complete or do not complete at all (timeout) - processes number increases significantly (~1000, which seems to correspond to recursive-clients default value) We have taken care of everything we can think of: - bind9 configuration - network configuration - arp resolution - firewall configuration (although being a CheckPoint firewall, Smart Defense does not seem to cause any issue since only logging is activated, cf http://groups.google.com/group/comp.protocols.dns.bind/browse_thread/thread/cfa8c63ec6bd08d6 . Firewall log does not show anything weird too.) Log do not show anything relevant to me, except the well known "too many timeouts resolving 'ns2.highergroundtech.com/AAAA' (in 'highergroundtech.com'?): disabling EDNS" message. We currently running BIND9 on Linux Debian: - the one running perfectly is a quite outdated 9.2.1-2.woody.1 package - the one causing problem is a quite up to date 1:9.5.0.dfsg.P1-2 package Configuration files have only been updated to reflect releases changes. Do you have any hint or advice so I can at least look at where the issue comes from and then try to solve it? Thanks for your help, Kind regards, cedric.
