Crashplan scripting question

[AlistairCarr]

Hi all,

Hoping someone can help me here. We're going to be deploying crashplan ProE out to our org soon.

In the installer script on the local machine there is a variable for %CP_USERNAME% (or similar) which needs to be the individuals email address.

Is there anyway to pipe the casper $EMAIL variable into the Crashplan username variable?

We do not have AD/LDAP to perform this function unfortunately.

Once again, thank you all in advance.

Yes, this could be done using one of the following methods:

You sir are a star, BUT how do i then get that information into the installer script that lives in the crashplan DMG on the local machine ?

The following white paper might help: Administering CrashPlan PROe with the Casper Suite

Basically, just use the code in the user info script (/Library/Application Support/CrashPlan/.custom/userInfo.sh) and set the "CP_USER_NAME" variable to the result of the command.

I created my installation package manually using Composer, and just put my custom.properties, userInfo.sh, and CrashPlan installer in /Library/Application Support/CrashPlan/.custom. In addition, I have a post-install script that runs the actual installer and removes the .custom directory once complete. The final piece of the puzzle is a custom script that is used in my deployment policies, which checks to ensure that requirements are met (i.e. the logged in user is the person that the machine is assigned to). If all of the requirements are met, it triggers the policy which actually installs the custom package.
