The rcman machine-update command enables you to set basic information, such as the description and alias. For example, on the machine "imap.company.com" you would enter this command:
rcman machine-update --desc="Mail server" --alias=imap imap.company.com
Permissions are managed using the commands rcman group-addmachine and group-delmachine, machine-addemail and machine-delemail, and so forth.
The rcman machine-listpackages command displays information about packages, and is equivalent to the command rpm -qa.
