sudo needs a long time to determine the host name

Bug Description

Whenever I try to run a graphical app (such as boot-admin, network-admin,
gnome-cups-manager) that need to be invoked trough sudo they suffer a great
delay before their window is showed in the desktop, though a "ps -A" in a
terminal shows that they are executing.

I've discovered that this problem is someway related to dhcp, because manually
running dhclient3 fixes the delay problems. But internet is already working
from the beginning so the network interface already has an ip assigned.

sudo needs to lookup your hostname in order to process its configuration file.
If your DNS server is slow or unreachable, this will cause delays.

But the DNS server is ok because all other network related tasks (firefox,
evolution) have no problems.

i have a fresh breezy install
for me "sudo nautilus" takes 3 min to start
"sudo gedit" doesn't start at all.
i don't know much about dhcp / dhclient3 so i didn't tried that way.
hope this helps.

sorry, my installation was broken
(i stepped throught some important network config durig the installation: after
dhcp failed i selected 'go back' and skipped few install options, which caused a
totally broken system)

It works fine for me without any noticeable delay. Maybe your /etc/hosts doesn't contain a line for 'localhost'?

Changed in sudo:
status: Unconfirmed → Needs Info

No answer for a long time, and if the reason is really the missing localhost line in /etc/hosts, then this is already covered by bug 32906.

i have the same problem.

- it takes a long time (> 3min) to start nautilus with sudo or gksudo
- sudo gedit does not start at all

i guess more programs are affected.

any clue, how to solve this problem?

thanks,
jido

forgot to mention that /etc/hosts contains a localhost line.

by removing the package GNOME-PPP the problem solved.

i don't know why, but it seems, that gnome-ppp is blocking sudo.

can someone reproduce this bug.

thank you,
jido
