DNS Timeout?

[Joel Shank]

I am setting up an NT DNS with a primary and backup for my UNIX environment. Does anyone know what the timeout value is and can I change it? If the primary DNS server is down, how long does it wait to determine it is down before going to the backup. I just tried it and it NEVER went to the backup DNS server.(?) (By NEVER, I really mean after a few minutes of waiting :-)

Hi,

found this:

Install the following patch:

For HPUX 10.20 install patch PHCO_20098 (libc:y2k:year2000:cumulative) or later

For HPUX 11.0 install patch PHCO_20493 (libc:10.20:compatibility) or later


Edit the /etc/resolv.conf and add the parameters retry and retrans. The
retrans is specified in milli-seconds. For example to configure the system to
only do 2 retries and to retransmit in 3 seconds, edit the file as follows:

domain mydomain.com
nameserver ip_of_nameserver1
nameserver ip_of_nameserver2
retry 2

edit your /etc/resolv.conf file
add all your nameservers and and a line for retry 2
the switch should be automatic if they are both in /etc/resolv.conf
