If you are using network-manager, you can easily Open nm-connection-editor and select the connection your are using, got to the ipv4 settings tab In the "Method" dropdown box, specify "Automatic (DHCP) adressess only", and set set your dns server and search domain to you wishes. When you then activate that connection in nm-applet, network-manager will not use the settings from the dhcp server but the one you've setup manually. hth, Michael -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?

Traditionally, it is started by "pon" and stopped by "poff". There are configuration settings for ppp which control this. Here's a link to some information about configuring ppp: http://www.wowway.com/~zlinuxman/tp600.htm#Config. This is in the overall context of my "Linux on ThinkPad 600" webpage, and it does not address your specific concern, but it does provide some basic information on configuring ppp. In particular, /etc/ppp/peers/provider looks like the file you need to edit. The "usepeerdns" option is apparently what you *don't* want. As to the domain name and IP address, that's pretty much up to your ISP. They control their own domain name, and they assign you an IP address. They probably control your hostname too, as seen by outsiders. But you *can* supply your own DNS servers if you want. You just have to make sure that you're not using the "usepeerdns" option. -- .''`.
