I've set up sudo not to prompt for password by editing the sudoers file:
myuser ALL=(ALL:ALL) NOPASSWD: ALL
And it works fine, running sudo with no password prompting. But when entering sudo -v I noticed that it prompted for password, only once.
When I create new Ubuntu 12.10 instances, I typically bootstrap them by manually SSHing onto the machine and editing the sudoers to put a NOPASSWD on the default user (e.g., ec2-user, azureuser, etc.). Then my install scripts can sudo various commands without having to provide a password.
I don't have anything against passwords.
I have a script run from a non-privaleged users' crontab that invokes some commands using sudo. Except it doesn't. The script runs fine but the sudo'ed commands silently fail.
The script runs perfectly from a shell as the user in question.
Sudo does not require a password. The user in question has (root) NOPASSWD: ALL access granted in /etc/sudoers.
Cron is running and executing the script.
sudo does not work.
I have installed Arch onto a USB key, using BTRFS.
The output of "sudo" is:

Hello
I add (visudo) to file sudoers:
Cmnd_Alias SENDFAX=/usr/local/bin/sendfax *
apache ALL=NOPASSWD: SENDFAX
When i use php script with command:
sudo sendfax -D -n -d number file > ok.log 2>> not-ok.log
I get
I'm trying to make my sudoers file allow a user to adjust the backlight without having to enter in the password. This is what I have:
# User alias specification
Cmnd_Alias ADJBL = /usr/bin/su -c "echo 150 >/sys/class/backlight/intel_backlight/brightness"
# For our user..
ouruser HOME=(root) NOPASSWD:ADJBL
..
I would like to be able to use the sudo command in a chroot environment.
I start the chroot as follows:
chroot /debian-squeeze /bin/bash
Now I'm logged in as root in the chroot. I can do su user to log in as a user named user.
I run ubuntu-12.04 desktop x86_64.
I have a simple script that needs to be accessible from the Desktop and run as root:
$ cat ~/Desktop/flash.sh
#!/bin/bash -
cd ~/tools
sudo ~/tools/fastboot-HW.sh
I've read this and that and that also.
In /usr/local/bin I've the following script called sdown
/usr/local/bin$ cat sdown
#!/bin/bash
if [ $# -lt 1 ];
then
echo "no time set"
else
sudo shutdown -h $1
fi
Permssions are 788: -rwxr-xr-- user user sdown
The point is if I run the script it's prompting for the sudo password:
/usr/local/bin$ sdown 13:37
[sudo] password for user:
Just to make my life even better I'd like to avoid
