I set-up a .bogus domain which worked as expected, I then scooped out all the .bogus bits and replaced with .local and it still didn't work. As you say, .local must be reserved. I thought it must be something specific to the client. I have now decided to use one of my .net domains for internal. I had been advised against making my own up since a ICANN are planning to create many new gTLDs in the future: http://www.icann.org/en/topics/new-gtld-program.htm The next challenge for me is configuring the domain to point to my own nameservers, which looks a bit fiddly with GoDaddy. -- GPG Key fingerprint = B323 477E F6AB 4181 9C65 F637 BC5F 7FCC 9CC9 CC7F “Live as if you were to die tomorrow.

This fact may be related as the .local domain is used (reserved?) for Avahi and mDNS. On Fedora, my /etc/nsswitch.conf file has the following: hosts: files mdns4_minimal [NOTFOUND=return] dns I expect Ubuntu's is very similar, so if the mdns lookup fails the entire host lookup will also fail. You could probably move mdns4_minimal to the end of the line, so your DNS takes precedence: hosts: files dns mdns4_minimal This might affect Avahi though, but if you don't care about it just remove or disable the Avahi services entirely. Or the best solution might be to change your internal domain sooner rather than later!

[Hampshire] Ubuntu Network Manager and local DNS zone not playing nice?
I've configured a private DNS zone imran.local [1] on my LAN, I'm using bind9 on Debian Squeeze. The problem is that while servers on the network will resolve and ping hosts in the private zone fine, the desktops (Ubuntu Lucid Lynx) do not when using a FQDN. $ dig xenserver.imran.local ;; QUESTION SECTION: ;xenserver.imran.local. IN A ;; ANSWER SECTION: xenserver.imran.local. 86400 IN A 192.168.98.30 My problem is that while I can ping by hostname... $ ping xenserver PING xenserver.imran.local (192.168.98.30) 56(84) bytes of data. 64 bytes from xenserver.imran.local (192.168.98.30): icmp_seq=1 ttl=64 time=4.12 ms 64 bytes from xenserver.imran.local (192.168.98.30): icmp_seq=2 ttl=64 time=0.245 ms 64 bytes from xenserver.imran.local (192.168.98.30): icmp_seq=3 ttl=64 time=0.245 ms ...which I would expect to work given my search domain. I cannot ping by FQDN: $ ping xenserver.imran.local ping: unknown host xenserver.imran.local $ cat /etc/resolv.conf # Generated by NetworkManager search imran.local nameserver 192.168.98.3 192.168.98.3 is Debian Squeeze running bind9. What is going on? I suspect NetworkManager as this works OK from another standard Debian server on my network configured to use 192.168.98.3 as DNS. One other thing to mention is that I had dnsmasq running. I think was installed with convirt package? Anyhow, I purged that package but that did not fix it. [1] Yeah, I know it's probably not good to make up your own TLDs, I plan to use a .net domain in future. -- GPG Key fingerprint = B323 477E F6AB 4181 9C65 F637 BC5F 7FCC 9CC9 CC7F “Live as if you were to die tomorrow.
