<header>Cluster Software Packages</header>
This Webmin module allows you to manage the software installed on
multiple servers in a cluster from the one interface. It is similar to
the Software Packages module, but with the ability to perform most
functions (like installation, querying and deletion of packages) on
many Webmin servers in one operation. <p>
The top part of the main page under the Managed Servers heading lists
other Webmin servers whose software is being managed by this module. To
add a server to this list, you must first add it to the Webmin Servers
module, with a username and password specified to login to Webmin on
that server. You can then select the server from the list next to the
Add Server button. <p>
When a server is added, the module will check to make sure it is using
the same package management system as this server (such as RPM or Debian),
and then download a list of all installed packages for caching locally. <p>
One server that will always appear on the list of those available to
add is 'this server', so that you can manage packages locally and on
multiple remote servers from the one interface. <p>
Once there is at least one icon under Managed Servers, you can use the
Installed Packages form to search for packages on all servers, or click
the Refresh package lists button to re-fetch the package list from all
servers if packages have been added or deleted via some other module
or method. <p>
At the bottom of the page is a form for installing new packages on
all the managed servers. You can select to install from a file on this
server, from an uploaded file or from a file downloaded via HTTP or FTP
from some other site. When installing from a downloaded file, you can
choose whether each managed server should re-download the package from
the original site, or receive a copy from this server. The former option
will be faster if the site the package is on is within your local network. <p>
