Mike,

Having not seen the original condition of your sudo script file I could only guess.  However members of the sudo group listed in /etc/group will only be given complete root privileges if the line "%sudo ALL=(ALL)  ALL" ;

1. Exists in the file.
2. It is uncommented (the '#' at the beginning is removed).

Additionally those in the sudo group will not have to type a password if the  "NOPASSWD:" option is:

1.  Added to the %sudo line described above, or
2.  It that original line is commented out and a new line with the option is added to it.

I hope this clarifies things a little.

Thanks James. Now it is acting like I want it to. But what about the thing where people were telling me to add the user to the group sudo? Why do you think that wasn't working?

Mike, the comment symbol in the sudo file is a '#' not a '%'.  The % in the sudo file flags the parser to read the attached trailing letters as a group.

Leave the line in /etc/group as you have it.

comment out the line:

      sudo ALL=(ALL:ALL) ALL 

Like this:

      # sudo ALL=(ALL:ALL)  ALL

and add a new line below it like this:

      %sudo ALL=(ALL)  NOPASSWD:  ALL

and also remove the following line completely from visudo

      bmike1 ALL=(ALL:ALL) ALL

Isn't the line that is commented out supposed to be that way,,,, wait a second! If I remember correctly the '%' is a comment symbol too. (if I rember right I was messing with a file that used % signs to comment out lines. I'll try removing it and see what happens.

Well I uncomented it and now the error is:

$ sudo visudo
bmike1 is not in the sudoers file.  This incident will be reported. (I'm terrified! lol)

So to me this is saying to put the line:

bmike1   ALL=(ALL:ALL) ALL

under the line:

sudo   ALL=(ALL:ALL) ALL

so it looks like:

# Allow members of group sudo to execute any command
sudo   ALL=(ALL:ALL) ALL                                         <-relevant line
bmike1   ALL=(ALL:ALL) ALL                                         <-relevant line


but you were saying I should just need to add my userid to the group sudo (which, as shown, is already done). So I am at a loss! What should I do.

Also, would someone explain the difference between usin a pound symbol and a percent when commenting lines.

Mike,

Don't know if it was explained above but the % symbol infront of the names in the sudo file is the reference for a group listed in the /etc/group file.  So the line 

%sudo ALL=(ALL:ALL) NOPASSWORD : ALL 

When uncommented (remove the # in front if it exists) tells Linux to allow anyone in the sudo group access to ALL commands as root without a password.  All you have to do is make sure this line is uncommented using visudo.

Then you would edit the /etc/group and add your username to the 'sudo' group line after the ':' on that line.  If there is already another user listed simply add a comma to the end of the previous name then a space and add your username at the end (without a comma after your username).

Caution:  This gives any and all users that are part of the sudo group complete root privileges without password requirements.  If this is an issue you can depending on your distro instead use the %wheel group listing in the sudo file. If the %wheel stanza exists (same as the %sudo ... above) and there is a group named wheel in /etc/group you could use this in lieu of %sudo.

Hope this helps.

By deleting the sudoers file and renaming the sudoers.bak file to
sudoers. Uh, you *did* make a backup of the sudoers file...didn't you?
