Excesive DNS requests

[xalfeiran]

Hi!

I have a Centos 5 Scalix 11.4 server, running its own DNS server, forwarding requests to the public domain DNS.

Having some internet issues ive checked my firewall logs and saw an excesive amount of dns requests from my scalix server to the outside dns, even though scalix servers runs its own local dns. i ran a wireshark sniffing session and saw most of the name resolving task is done by the outside dns server, insted of the one running on the same server

any clue for this? centos is only running scalix service and dns server

thanks in advance!

Sounds like you need DNS caching turned on.
