To install NICI on UNIX servers, the person doing the installation must either be logged in as root or have root access. The Sudo utility provides an easy way for a system administrator to delegate root access to another user to perform specific tasks.
As with any delegation of rights, the system administrator should take the necessary precautions to ensure that the company's standards of security are followed.
Most UNIX providers have the Sudo utility available on their Web sites. You can also download the utility from the Sudo Web site. The Sudo documentation provides information on how to install and configure the utility. When it is configured properly, you can install NICI by entering sudo install_command.
