Good. DHCP should automatically provide you with a nameserver. And hopefully that nameserver will be working! That would be extra nice. But it is possible that it hasn't. > # dpkg -l bind The package name is bind9 not bind. But if you didn't select the task then you wouldn't have it installed. > # cat /etc/network/interfaces > # This file describes the network interfaces available on your system > # and how to activate them.

Effectively it is empty. NetworkManager will automatically run dhcp on any interface NOT mentioned in that file. Since none are mentioned due to the commented out part it means that NM is going to do DHCP on that interface. I think what the package does there is a hack. But here is why it is doing it that way. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=530024#49 > # cat /etc/resolv.conf > # Generated by NetworkManager > nameserver 192.168.1.254 DHCP gave you 192.168.1.254 as the nameserver. This is probably your local router. > # grep hosts /etc/nsswitch.conf > hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 I have never seen the mdns4 parts installed upon a pristine install of Debian. I can only guess that something you installed edited that file and made those changes. Probably related to avahi or zeroconf or some such. That mdns_minimal4 [NOTFOUND=return] part bothers me because it says that if the domain is a multicast domain (by default .local) and it isn't found in the multicast lookup then return immediately host not found and stop looking and never look in dns for it. If you don't have mdns setup then you don't need that configuration. And if you do have it setup then you already don't need it since you would already know enough to set up your own domain normally. Saying this will bring all of the people who love mdns out of hiding and they will post how good it is for them here. I know this but will say it anyway. Regardless it will help narrow down the problem. Edit that line and make it like this: hosts: files dns Does that solve the problem? If not then test that your dns server is fuctional. You can do this using a number of different utilities that are all very similar and give the same information but in different ways. I prefer the bind9-host package's "host" command. I believe it is installed by default. Others will prefer either nslookup or dig. Try using it directly against the nameserver. As long as the answers seem reasonable you could use any of the utilities available to you. $ host www.debian.org 192.168.1.254 www.debian.org has address 128.31.0.51 www.debian.org has address 206.12.19.7 www.debian.org has IPv6 address 2607:f8f0:610:4000:211:25ff:fec4:5b28 $ host slashdot.org 192.168.1.254 slashdot.org has address 216.34.181.45 If that doesn't look up names correctly then the problem is on your upstream nameserver and not on your new installation. Assuming that you are not looking up .local names. In which case you might have to probe into your router to figure out what is happening there. It is being advertised through DHCP has a nameserver and therefore should proxy dns lookups through it. > 127.0.1.1 sunny You have a positive outlook on life. I like that.
