Hi, I am using python version 2.7.3 on UBUNTU. I am using 'sudo' to run a bash command in login page. It is giving me error 'sudo unable to resolv host 'hostname'.
In the command line, when I use the command 'sudo hostname', it is giving me the error as well as the output. Can any one help... please?? This is my sudoers file. Please suggest me the changes in sudoers file if any:

# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
#

#Defaults       env_reset
#Defaults        requiretty

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL) ALL
tester  ALL=(ALL) NOPASSWD: ALL
www-data ALL=(ALL) NOPASSWD: ALL
# Allow members of group sudo to execute any command
# (Note that later entries override this, so you might need to move
# it further down)
%sudo ALL=(ALL) ALL
www-data ALL=NOPASSWD: ALL

Your syntax is wrong for www-data, look at some of the other users

Just another question? Why are you trying to give your www-data user permissions to run sudo on any command with NO password. That's a HUGE security hole. At the most, you should only allow it to run a specific command.

As per the error info "sudo unable to resolv host 'hostname" the issue may be in host file

Go to System -> Administration -> Network -> Hosts

Check the entry for 127.0.1.1 and see if it matches the hostname. Also paste the following output

cat /etc/hosts
