The resolv.conf supports a line called options that allows for some fine tuning of the behavior of the resolver. In my environment we are using ISC's DHCPD to provide DHCP services to our services. Currently I can set the search and nameserver fields in the resolv.conf fine via DHCP, but I also want to be able to create the following line:
options timeout:2 attempts:4
Does anyone know if this is possible?
I have the following resolver related DHCPD options set currently:
option domain-search "example.com"; option domain-name-servers 192.168.1.1, 192.168.1.2, 192.168.1.3, 192.168.1.4;
In this particular case, the systems are all running CentOS 5/6.
