Full Discussion: One of the two DNS server going down causes impacts
Top Forums UNIX for Advanced & Expert Users One of the two DNS server going down causes impacts Post 303043107 by broy32000 on Saturday 18th of January 2020 07:56:52 AM

DNS servers are Windows 12. I do not have much control over those. Is there anyway to increase the verbosity of logging in AIX client?

The AIX clients are running AIX 6.x , as far as I remember. To me it's a puzzle that the services are impacted when the 2nd server in /etc/resolv.conf file goes down. I have not tested what happens if the first one goes down and the 2nd one remains up.

THANKS
