%general-entities; ]> $LastChangedBy$ $Date$ sudo The sudo package allows a system administrator to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while logging the commands and arguments.

Now, as the root user: make install --with-ignore-dot: This switch causes sudo to ignore '.' in the PATH. --with-all-insults: This switch includes all the sudo insult sets. --enable-shell-sets-home: This switch sets HOME to the target user in shell mode. --disable-root-sudo: This switch keeps the root user from running sudo, preventing users from chaining commands to get a root shell. --with-logfac=auth: This switch forces use of the auth facility for logging. --without-pam: This switch disables the use of PAM authentication. Omit if you have PAM installed. --without-sendmail: This switch disables the use of sendmail. Remove if you have a sendmail compatible MTA. --enable-noargs-shell: This switch allows sudo to run a shell if invoked with no arguments. There are many options to sudo's configure command. Check the configure --help output for a complete list. /etc/sudoers /etc/sudoers The sudoers file can be quite complicated. It is composed of two types of entries: aliases (basically variables) and user specifications (which specify who may run what). The installation installs a default configuration that has no privileges installed for any user. One example usage is to allow the system administrator to execute any program without typing a password each time root privileges are needed. This can be configured as: # User alias specification User_Alias ADMIN = YourLoginId # Allow people in group ADMIN to run all commands without a password ADMIN ALL = NOPASSWD: ALL For details, see man sudoers. The Sudo developers highly recommend using the visudo program to edit the sudoers file. This will provide basic sanity checking like syntax parsing and file permission to avoid some possible mistakes that could lead to a vulnerable configuration. If you've built Sudo with PAM support, issue the following command as the root user to create the PAM configuration file: sed -e 's@/su@/sudo@' -e '/pam_rootok/d' \ /etc/pam.d/su > /etc/pam.d/sudo Installed Programs Installed Library Installed Directories sudo, sudoedit, and visudo sudo_noexec.so None Short Descriptions sudo executes a command as another user as permitted by the /etc/sudoers configuration file. sudo sudoedit is a hard link to sudo that implies the -e option to invoke an editor as another user. sudoedit visudo allows for safer editing of the sudoers file. visudo 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). sudo_noexec.so
