Re: Is possible to postpone changes made to /var/run/resolv.conf ?

Hello,
we are developing VPN service on Leopard and we want to create the same behaviour like PPPoE has. When we are establishing our vpn tunnel, we inform dynamic store about our IP and DNS server, but resolv.conf is not modified by the system.

The resolv.conf file, which only get used by a small handful of DNS command line tools (e.g. nslookup), reflects the DNS configuration of the "primary" network service. The real configuration can be viewed with the "scutil --dns" command.

If you want your VPN's configuration to be used than you'll need to have your service at the top of the service order (or use the OverridePrimary key).

My first question is: Should we modify this file manually (via file functions) ? 

No.

And my last question is: I modify resolv.conf manually but when I tried to change DNS via System Preferences, configuartion daemon will revert all my changes back. :-( Can I block this action until my vpn tunnel is active ? How ? By hooking something ?

You cannot block SC's updating of the resolv.conf file and, as I noted above, the file is only used by a small handful of command line tools.
