Is there any advanced feature of NM that will have it invoke a script when a new connection is created? Most specifically I'm interested in replacing the default handling of /etc/resolv.conf updates with my own handling.
What I'd really like is something similar to the facility in dhclient which allows you to define your own processing for resolv.conf updates, providing details about the search and nameserver entries which are being added for that interface via the environment or command line arguments or whatever. I've recently been put into a new position of needing to attach to two or more private subnets at the same time; each of these has their own internal DNS server which, in addition to serving global hostnames also resolves private hostnames... and I need to be able to access hosts on more than one private subnet at the same time. The default behavior of NM in this situation doesn't work for me: only the DNS servers from the "last" VPN connection I create are used and so private hosts on the earlier subnets can't be resolved. I've been banging my head against this for a week or so, hand-tweaking resolv.conf etc. I've installed, messed with, and ultimately uninstalled the resolvconf package (I'm on Ubuntu 10.10): it's a nice idea but it requires all modifiers of resolv.conf to be changed to use resolvconf instead, and (for example) the openconnect VPN package doesn't do this. I've come up with a way to make this work by using dnsmasq as a local proxy DNS server, and adding "server" lines to force it to use different DNS servers for different network domains. When I configure it by hand it works quite well. However, in order to make this work seamlessly I need to get NM to give me control over the updates to resolv.conf, so I can instead update the dnsmasq configuration. Even if I could just run a generic "post-connect" script I could work out the changes I need to make by examining the contents of /etc/resolv.conf after the connection comes up, and do them myself. Any help here? Thanks! _______________________________________________ networkmanager-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/networkmanager-list
