Sudo help

[mdraja]

Hi

How do u use sudo to su to root without having to provide a password.
My username is userA who is in group system

My sudoers file is as follows:


root ALL=(ALL) ALL
userA ALL=(ALL) ALL

When I type:

/usr/local/bin/sudo su - root

I still get prompted for a password and I would like to go straight in

Any help greatly appreciated

AFAIK you don't

sudo allows users to run any command that is configured for them - even those normally run by root.

It is not a method of su'ing to root without a password

And the password it is asking you for is not root's, it is your ordinary user name.

Also, if you do a sudo su - root, you are totally defeating one of the best parts about sudo: logging what commands are being executed and from where they are executed. You would be better off if you do something like:

sudo 1stcommand

then

sudo 2ndcommand

If you sudo 2ndcommand within about 5 minutes of the first use of sudo, you will not be prompted for the password again.
