What is the best approach to keep dhclient from overwriting /etc/resolv.conf every time it gets a new lease on an IP address? This has been a frustrating search as Google has turned up next to nothing on the issue other than a hack into a script file which should be overwritten when world is rebuilt. Thanks in advance, Tom Veldhouse

Something like: interface "int0" { supersede domain-name "example.com" supersede domain-name-servers "127.0.0.1" } HTH, Karol> Thanks in advance, > > Tom Veldhouse-- Karol Kwiatkowski <freebsd at orchid dot homeunix dot org> OpenPGP: http://www.orchid.homeunix.org/carlos/gpg/0x06E09309.asc -------------- next part -------------- A non-text attachment was scrubbed...

hi,
this is not the correct list to ask, but anyway.
"man dhclient.conf" would learn you to use supersede and prepend
statements.
interface "xl0" {
supersede domain-name "yourdomainname.com";
prepend domain-name-servers www.xxx.yyy.zzz;
}
adjust xl0 to your dhclient interface,
yourdomain is search first for hostname lookups
xyz is prefered first nameserver in the resolv.conf
