System Administrators have responsibility for maintaining, adding, and updating software on the system. As has been discussed the software package management tools greatly simplify this function. Webmin supports both RPM and Debian packaging schemes. Packages can be managed through Webmin by selecting the software packages button. Figure 369 shows this screen.
The system package database can searched to see if a particular package is installed by entering the package name in the area to the right of the Search for Package button then clicking on that button. Note that the local file system can be browsed for a package by clicking on the button to the right on it.
New packages can be installed from either the local file system (maybe from a mounted CDROM) or the searched for on the Web (through rpmfind.net or apt for Debian packages), then the package can be downloaded and installed by using the install new packages section.
The Identify A File area can be used to find which package installed a particular file on the system. This is useful to help identify what resources or files a particular package has provided.
Finally, system updates can be performed in the Upgrade All Packages Area. This is an easy way for administrators to apply fixes and updates to their systems.
