Using kdesu or sudo without password

Krister Hallerg · #1 2nd January 2007, 12:43 PM

I would like to be able to use Software Updater (pup) and Add/Remove Software (pirut) without having to enter a password every time.

So I used visudo to edit sudoers, unblocking %wheel ALL=(ALL) NOPASSWD:ALL
and added myself to the wheel group.

When using kdesu ("kdesu /usr/bin/pirut") I get asked for the password, so I may as well do without using kdesu. When using sudo ("sudo /usr/bin/pirut")it will not load the application pirut. (pup)

"sudo konqueror" does not seem to give me root access to files

Could live with entering the Password, but it would be nice to do without it, if anyone could help me, Thanks

Am a bit disappointed that nobody can give me a tip how to get rid of all these entries of passwords. Cheers!

I'm trying to figure this out too. So far in the sudoers file I used lines:

root ALL= NOPASSWD: /usr/bin/kdesu /usr/bin/pirut
jamesjpn ALL= NOPASSWD: /usr/bin/pirut
jamesjpn ALL= NOPASSWD: /usr/bin/kdesu /usr/bin/pirut

but none of these work. If you have made any progress, please share it!

I cant answer this as I dont know but I would like to say that you might not want to go this route. The root system is in place for your protection. There are good reasons why you need to su to install or change any software. If you want to bypass this you might as well just install XP and use that.

OK, I found something that can work from the command line. First of all, I added to sudoers:

jamesjpn ALL = NOPASSWD: ALL

(Replace jamesjpn with your user name)

Now when pup gives me a message of updates, I open terminal and enter this command:

sudo pup

And now I'm not prompted to type a password!

I'm never going back to XP! Fedora Core rocks! IMHO, because I'm the only soul with access to my machine, I don't think it's poor security to bypass a prompt for a password for convenience sake. I've already typed a password to get into my user account, why type another? Am I now more vulnerable to hackers by editing the sudoers file to bypass having to type the root password? I'm still a relative newbie in using Linux for only the past 2 years and am always seeking to learn more. Any comments are appreciated.

Cool. Thanks!

no, you are good. You said the magic words, in a business environment what you did is a no-no, but as a home user as long as you trust everyone around your computer it wont matter. Just as long as you still have to physically allow anything to install itself you should be fine.

Thank you for your advice and encouragement! I want to learn all I can to help others move from Windows to Liinux. From what I heard about Windows Vista, things are looking pretty bleak. Perhaps it will encourage more people to move to Linux. I'm glad I moved when I did.

Had given up on this thread, but happened to see that there has been some posts. Thanks jamesjpn!

Adding to this line to /etc/sudoers:
krister ALL=NOPASSWD: ALL

This does not solve my problem. Neither "sudo pup" or "kdesu# works. I get the following messages with "sudo pup":

Am I doning something wrong?

Hi Krister,

I used to get the error message:

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

in Fedora Core 5 when I ran the sudo command followed by the program I wanted to run in root. For example every time I tried sudo gedit I would get that error message and gedit wouldn't load. But for some reason this seems to be fixed in FC 6. The sudo pup command works fine for me. I just don't know what to tell you. I myself am still a relative newbie of only 2 years in Linux.

Krister Hallerg · #13 8th February 2007, 05:26 PM

Thanks jamesjpn. I am a relative newbie too, 18 months in Linux. Interesting what you say about FC5. I did not do a fresh install of FC6, but upgraded from FC5.

It is not just pup that dows not work for me. sudo pirut is the same. sudo kate works and i can open log-files in the root directory. sudo konqueror seems to work, but I cannot open log-files in the root directory because I dont have permission. With seem to work I mean that I am not asked to enter password, which is the point of my query.

Anybody else that can help? This works with SuSE, Kubuntu and Mandriva, why not Fedora??

Krister Hallerg · #14 10th February 2007, 04:33 PM

Tried a fresh install of FC6 (instead of upgrade), and yes, now I can sudo pup and sudo pirut without being asked for a password. Have to tick the run in terminal box though.

You must be using the Run Application applet. I have a shortcut to Terminal on my Gnome panel that I just click to open a Terminal window and then type commands. To each his own. I wish I could figure out how to make a launcher icon on the Desktop to run sudo pup, but so far it hasn't worked.
