Changing DNS nameserver Timeout

Scott Torgerson — Mon, 26 Mar 2001 19:13:05 GMT

Does anybody know a way to make DNS go to the next "nameserver" entry in the /etc/resolv.conf file faster, if the the first one is down or not responding? If the first nameserver is not responding, it takes to long to go to the next entry.

Scott,

Here are a couple of links to documents I found in the TKB:

Hi,

Add the following line in your /etc/resolv.conf:

retrans [time in 1000th of a second]

If you want the timeout to be in 1 second, then the retransmit should be:

retrans 1000

Since retry is only once (the default setting I am recall correctly), the retransmit is analogous to a timeout.

Hope this helps. Regards.
