Big thanks!

Thanks.

You are correct. For those who are not familiar with sudo under FreeBSD here is small how-to:

1) What is sudo?
sudo is security tool/utility which allows a permitted user to execute a command as the superuser or another user, as specified in the sudoers (/usr/local/etc/sudoers) file. It supposes to replace traditional su command which is discussed above.

2) How do I install sudo?
By default, sudo is not installed; you can install it from ports collection or from installation media such as DVD/CDROM. However, make sure it is not installed with following command:
#pkg_info | grep sudo

If sudo package already installed it will display in output else use any one of the following method to install sudo.

Method # 1 : Install sudo from CD/DVDROM
a) Login as root user

b) Mount cdrom drive
# mount /cdrom

c) Change directory to security directory where sudo binary package is stored on disk:
# cd /cdrom/packages/security/

d) Install the sudo:
# pkg_add -v sudo*

Method # 2: Using ports (recommended)

a)Goto sudo ports directory:
# cd /usr/ports/security/sudo

b) Download, compile and install sudo:
# make install clean

Main sudo configuration file is usr/local/etc/sudoers. You can edit this file directly or use visudo command

rdl fbsd.test.com=/sbin/su

Save the file

rdl : Name of user who can execute /sbin/su command for fbsd.test.com host

Now you rdl can execute the command (when prompted for password supply rdl users password)
$ sudo /sbin/su

See su and sudo man pages for more information.

try ‘sudo su’ and you will be promoted to root WITHOUT enabling root!
