You can upgrade an existing ClearOS 6 system to 6.4.0 Beta 2 using the following command:

yum --enablerepo=clearos-updates-testing upgrade

Beta Testing Details

Storage Manager

The new Storage Manager app provides a clean way to separate app data from the underlying operating system. Flexshares, web proxy cache, mail stores and other data intensive apps are mapped to /store on the file system. This /store could be a separate RAID partition, an external store, or an Amazon S3 store.

By default, the /store directory is used by the Storage Manager. If you are in a VM environment, you can attach another disk to your virtual machine and then mount it to /store. In future test versions, you will be able to do this via the ClearOS web-based administration tool. For now, we're the storage manager is only available with Amazon EC2 images.

Upstream Proxy

One of the features added to ClearOS 6.4.0 is support for upstream proxies. The initial testing for this feature requires some command line knowledge as well as direct access to the Internet (e.g. no proxy!). Once we are comfortable with the stability of the new feature, we will roll it into the release. In the ClearOS 6.4.0 Beta 2 release, you can see an Upstream Proxy step in the first boot wizard by running the following command before starting the wizard:

yum --enablerepo=clearos-updates-testing install app-upstream-proxy

Antimalware File Scan

To install the Antimalware File Scan run:

yum --enablerepo=clearos-updates-testing install app-file-scan


To install the RADIUS Server run:
