Hardly. The provider is welcome to provide their own nameserver as a service, but I certainly can (and in this case want to) use another. Also, since the machine is always in the same place, there's no need for the nameservers to change unless I say so. As for the internal domain name of my machine (and my network for that matter), that should also be up to me to choose. This would not be relevant for servers which need to have the same name internally and as seen from the internet, but for a home machine it makes sense to set the machine name and domain name independent of the provider. > You've still never answered why you *care* about whether resolv.conf > gets overridden on a regular basis.

It doesn't work because my provider's name servers do not. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkui6OMACgkQ+VSRxYk4409jyQCg5kAaXXZp3caGXc5AeFTYtB3W kzAAnAwT5xhGDRKTMZGUf4Fa+cCXPNdJ =plcE -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Had there also been a description which file to edit instead, it would even have been a helpful comment. But there hasn't, so it isn't helpful. Also the comment stated "generated by resolvconf", indicating that resolvconf was the program that changed it. But as I said it still happened to me after deinstalling resolvconf. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkui6qQACgkQ+VSRxYk440+B3ACgmUwELLACZJt6sM4WQElZf/S6 1HsAnjwAPylvSYUsut0ewM2GwY3/0kp5 =3tYh -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

If your machine is connected directly to your ISP (and that's what happens during dial-up) *you* become part of *their* network. >> You've still never answered why you *care* about whether resolv.conf >> gets overridden on a regular basis. > > See above. > >> As long as The Internet Just Works, >> why do you care what's in resolv.conf? > > It doesn't work because my provider's name servers do not. > You know, there's so much stuff you didn't tell us, which would have made this thread sooo much shorter if you had told us earlier. -- Obsession with "preserving cultural heritage" is a racist impediment to moral, physical and intellectual progress. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

From: Tom H on 19 Mar 2010 06:20 In one of the first responses to your email, Camaleon said that there were three possible culprits: 1. The resolvconf program 2. The network-manager daemon 3. DHCP clients You have said that you have uninstalled the first two, so you just have to configure the last one not to request name servers from the ISP's dhcp server and to add your own by editing /etc/dhcp3/dhclient.conf if you have dhcp3-client as your dhcp client -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Try this as root: grep -R /etc/resolv.conf /etc/* or this: for d in $( echo $PATH | sed 's/:/ /g' ); do grep /etc/resolv.conf $d/*; done Mike -- Satisfied user of Linux since 1997.
