[opensuse] nslookup works, ping doesn't ???
All, I've just had a problematic upgrade of a fileserver. (I ran out of diskspace on the upgrade as well as some other issues.) Anyway, I can now boot to init 3, but my nameserver resolution is not working. I think I have the NIC set correctly in yast (ncurses version). I can ping local machines by IP. I can do: nslookup yahoo.com 127.0.0.1 and nslookup yahoo.com 10.0.1.44 (my desired primary dns server) Both those give the expected result. But "ping yahoo.com" comes back with unknown host. What gives?

Hi - make a backup of your /etc/resolv.conf file. - then make a new one containing nameserver 8.8.8.8 nameserver 8.8.4.4 <empty new line here> - make sure it's readable by everyone i.e. 644. - I'm not 100% sure, but to me your switcher file looks ok. -- ------------------------------ Med venlig hilsen/Best regards Verner Kjærsgaard Open Source Academy +45 56964223 Novell Certified Linux Professional 10035701 Linux Counter no 114954 ------------------------------ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi
- make a backup of your /etc/resolv.conf file. - then make a new one containing
nameserver 8.8.8.8 nameserver 8.8.4.4 <empty new line here>
- make sure it's readable by everyone i.e. 644.
- I'm not 100% sure, but to me your switcher file looks ok.
thanks Turned out I had a file /etc/resolv.conf.backup.by.convert_to_netconfig or something like that. I moved the new resolv.conf out of the way and copied the above into it. I'm working now. And I already started a zypper dup. Thanks Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
