tags 635322 confirmed thanks Hello Vincent, this bug recently started happening to me as well, and even after normal shutdown-bootup cycles: my hostname is changed to "dhcppc0" (I suspect that's what my router sends), and X applications seem not to work anymore. Thus I'm also confirming its severity.

WICD provides a "send host-name $_HOSTNAME", hostname which you can set in the UI. That option is in /etc/dhcp/dhclient.conf , which is provided by isc-dhcp-client. > I'm not sure what it's supposed to do, but changing the hostname is certainly > a bug.

The *request* statement is described in dhclient.conf(5). I suspect the problem is that dhclient doesn't consider the config file provided by WICD anymore: this way we would have a "request host-name", but no "send host-name" -- thus effectively requesting a new hostname to the DHCP server. I'll investigate this better. David -- . ''`.
