Package: isc-dhcp-client
Version: 4.1.1-P1-17
Severity: important
Tags: upstream
I am not sure if this is the right package against report this, but anyway I
will tell what happened to me.
I joined a wi-fi network using wicd, and it automatically started dhcp client
to obtain an IP address. The problem was that the dhcp had changed my hostname
as well.
As a consequence, i was no longer able to start kde applications, because they
were unable to connect to my display (they use the local hostname i suppose).
I've also tried with iceweasel obtaining the same result.
salvo@lalala:~$ kcalc
No protocol specified
kcalc: cannot connect to X server :0
salvo@lalala:~$ iceweasel
No protocol specified
No protocol specified
Error: cannot open display: :0
To be fair, i am not entirely sure in which package the problem lies, i hope
you can reassign it if i was wrong in reporting here.
Regards

That seems fixed (at least to some extent) in 4.2.2-2:
if [ -z "$current_hostname" ] ||
[ "$current_hostname" = '(none)' ] ||
[ "$current_hostname" = 'localhost' ] ||
[ "$current_hostname" = "$old_host_name" ]; then
if [ "$new_host_name" != "$old_host_name" ]; then
hostname "$new_host_name"
fi
fi
I.e. if the current host name doesn't match the previous one from dhcp
then don't change it.

Julien
