GTM: named daemon listening on port 53 instead of GTM???

Hi,

 

 

We are using the F5 GTM for intelligent DNS load balancing.

 

 

The named daemon listens on port 53 and catches all DNS traffic, I would have expected to see the GTM process listening instead. How is the interaction done between named and the GTM process so that a decision can be made if the GTM should intercept the DNS request (or not)?

 

 

 

This seems to indicate two possibilities:

 

1) The named binary has been modified by F5

 

2) There is a redirection in the named.conf

 

 

 

Here's what I'm basing my analysis on :

 

 

[root@pradnspub01:Active] config netstat -anp|awk '/:53/'

 

tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 1414/named

 

tcp 0 0 127.1.1.1:38324 127.1.1.2:53 ESTABLISHED 1088/gtmd

 

tcp 0 0 ::1:53 :::* LISTEN 1414/named

 

udp 0 0 127.0.0.1:53 0.0.0.0:* 1414/named

 

udp 0 0 ::1:53 :::* 1414/named

 

[root@pradnspub01:Active] config

 

 

 

Thanks in advance.
