  • Sudo (su "do") allows a system administrator to give certain users (or groups of users) the ability to run some (or all) commands as root while logging all commands and arguments. Sudo operates on a per-command basis, it is not a replacement for the shell. Its features include: The ability to restrict what commands a user may run on a per-host basis. Sudo does copious logging of each command, providing a clear audit trail of who did what. When used in tandem with syslogd, the system log daemon, Sudo can log all commands to a central host (as well as on the local host). At CU, all admins use Sudo in lieu of a root shell to take advantage of this logging. Sudo uses timestamp files to implement a "ticketing" system. When a user invokes Sudo and enters their password, they are granted a ticket for 5 minutes (this timeout is configurable at compile-time). Each subsequent Sudo command updates the ticket for another 5 minutes. This avoids the problem of leaving a root shell where others can physically get to your keyboard. There is also an easy way for a user to remove their ticket file, useful for placing in a .logout file. Sudo's configuration file, the Sudoers file, is setup in such a way that the same Sudoers file may be used on many machines. This allows for central administration while keeping the flexibility to define a user's privileges on a per-host basis. Please see the samples Sudoers file below for a real-world example.
