Question
How can I use a Linux computer as a Package Server without installing the Package Server Agent?

Answer

There is an alternative that may be implemented instead of using the Linux/Unix computer as a Package Server. You may want to keep this in mind. It is a workaround that has been implemented by several customers already.

The scenario is that the Unix/Linux computer is not actually a Package Server and the PS agent is not installed on it. The Unix/Linux computer is instead used as a "file store and access point," so to speak. This computer must be running web server services, such as Apache since unix/linux clients can only download packages via http from a valid URL.

To implement this:

  1. The Unix/Linux packages are configured as follows:
    1. The "Package Location" contains a URL to the package on the Unix/Linux computer from which the clients will download the package. This must be a URL.
    2. The "Package Directory" is how the Notification Server will access the package and update the package hash code. This can be a UNC or a URL.
  2. Copy the package files to the Unix/Linux computer in the specified HTTP accessible directory.
  3. Copy the package files to the specified NS server package directory.

Basically, we are telling the clients to get the package from a URL somewhere other than the NS server or a PS server. This can be any valid URL. Clients do not know the difference. They are simply being told to download the package from some URL. They will download both the snapshot and the codebase files from the NS server.

Since there is not a PS agent, the Unix/Linux box cannot automatically update the packages as they change on the NS server. There are a couple of options that can be implemented regarding package updating:

  1. Manually update both the NS server package and the Unix/Linux package files and set the package delete option to anything other than immediately. This allows the NS server to update the package hash and provides updated files for the clients to access from the Unix/Linux computer.
  2. Alternatively, you can disregard the package on the NS server (other than for initial creation) and only update the package on the Unix/Linux computer. In order to ensure that the clients always get an updated package, you can set the package delete option to "0 days - delete immediately". This will cause the clients to download the package every time the client runs the task. Obviously, there is increased network traffic and processing on both the client and the Unix/Linux computer.

Note that the Unix/Linux computer, whether a PS or a simple file store, must be resolvable by hostname—either via DNS or by adding the Unix/Linux computer's IP address and hostname to the client's /etc/hosts file.
