Introduction to Sudo

Sudo (su "do") allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.

make install &&
if [ -f /etc/pam.d/su ]; then
  sed "s/su$/&do/" /etc/pam.d/su > /etc/pam.d/sudo
fi

Multilib

32Bit

CC="gcc ${BUILD32}" ./configure --prefix=/usr --libexecdir=/usr/lib \
    --enable-noargs-shell --with-ignore-dot --with-all-insults \
    --enable-shell-sets-home &&
make

if [ -f /etc/pam.d/su ]; then
  sed "s/su$/&do/" /etc/pam.d/su > /etc/pam.d/sudo
fi

N32

Compile the package:

CC="gcc ${BUILDN32}" ./configure --prefix=/usr --libdir=/usr/lib32 --libexecdir=/usr/lib \
    --enable-noargs-shell --with-ignore-dot --with-all-insults \
    --enable-shell-sets-home &&
make

Install the package

make install &&
if [ -f /etc/pam.d/su ]; then
  sed "s/su$/&do/" /etc/pam.d/su > /etc/pam.d/sudo
fi

64Bit

Compile the package:

CC="gcc ${BUILD64}" ./configure --prefix=/usr --libdir=/usr/lib64 --libexecdir=/usr/lib \
    --enable-noargs-shell --with-ignore-dot --with-all-insults \
    --enable-shell-sets-home &&
make

Install the package

make install &&
if [ -f /etc/pam.d/su ]; then
  sed "s/su$/&do/" /etc/pam.d/su > /etc/pam.d/sudo
fi


Configuring

To edit the protected sudoers config file, use "visudo"

To allow a user full root rights with out a passward, add the following to the file.

${username} ALL=(ALL) NOPASSWD:ALL

For more options, read the config file, and the man pages.....

Content

Installed Programs: sudo, sudoedit, and visudo
Installed Libraries: sudo_noexec.so
Installed Directories: None

Short Descriptions

sudo executes a command as another user as permitted by the /etc/sudoers configuration file.
sudoedit is a hard link to sudo that implies the -e option to invoke an editor as another user.
visudo allows for safer editing of the sudoers file.
sudo_noexec.so enables support for the "noexec" functionality which prevents a dynamically-linked program being run by sudo from executing another program (think shell escapes).
