Code42 apps on Linux typically require that you install the configuration package libgconf-2-4. If that package is missing, Code42's initial install alerts you, but an upgrade fails silently. To install the package, type the following in the terminal:sudo apt-get install libgconf-2-4
After you install libgconf-2-4, your Code42 app should work normally.
Dependency on libXScrnSaver
On Red Hat Enterprise Linux 7, the Code42 app requires the package libXScrnSaver. If that package is not present, the Code42 app installer prompts you twice for permission to install the package. We recommend you reply Yes to both prompts:
Without libXScrnSaver, the Code42 app service runs, but the app cannot open on desktops.

Crashplan App Download
To configure the CrashPlan engine you have to install the software on your machine, and redirect the GUI to connect with the Drobo. To do this, you need to establish a port forward from your desktop to the Drobo. Something like this should do the trick:
ssh -L 4200:localhost:4243 root@drobo-5n
Short explanation: this forwards any connection attempts to port 4201 on your machine to port 4243 on the Drobo. Once this is done, you have to tell the CrashPlan client to connect to port 4201 instead of the default (4243). To do this on a Mac, edit the file ~/Library/Application Support/CrashPlan/ui.properties and add this line:
servicePort=4200
Save the file, and start the app. It will ask for the credentials to be used on the Drobo. Once logged in, if the folder selection screen shows the path /mnt/DroboFS/Shares, then congratulations, you have CrashPlan on your Drobo.
