Bug Description
On a newly-updated Hardy beta install I selected System -> Administration -> Network and chose my wired interface and Properties. The interface had the "Roaming mode" checkbox enabled and it was able to use DHCP to obtain an IP address, etc.
I unchecked the Roaming Mode box and selected DHCP in the "Configuration" box, then added my domain name to the "General" tab (the hostname was already there) and clicked OK and close.
I rebooted my system, and it was a huge mess:
1) My ethernet interface was configured for IPV6 (!!) and no DHCP request was made (according to the log files). This means I couldn't access any of my DNS servers, which are only available via IPV4, among other things.
2) My /etc/hosts file did not have an entry for my hostname "myhost"; there was ONLY an entry for "myhost.
Since I couldn't sudo I had to reboot off my CD, mount my root partition, and edit my /etc/hosts file to add "myhost" to the 127.0.0.1 IP address. Then I was able to reboot and re-enable roaming mode and thus get my eth0 interface to use ipv4 again.
I'm not exactly sure what changing the configuration in network-admin is supposed to do. I did see that it added a line "iface eth0 inet dhcp" to my /etc/network/
thanks for reporting, is this reproducible with non-beta releases?
