Feb 03, 2012GTM: 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.
