Disable probe CRC Magic Key Check

    Hello, I am setting up some custom robot monitoring for a Citrix xenapp environment and the last thing that is not working is the probes CRC magic key check. Is there a way to disable this? When the xenapp boxes start up, all their probes are in the red ERROR state and I have to r-click, Security - Validate.

    How do we disable this crc check?

    It's not possible to disable - this is an important security feature which prevents a malicious virus or entity from modifying or replacing the executable file.

     

    However you can probably work around this by editing the controller.cfg file

     

    look for the probe(s) in question and you will see a line like:

     

    magic_key = ABXCWJH2390239D2093DJASLKDJALKSDJ232

     

    Delete this entire line from the section for the probe(s) in question and they should automatically re-validate on startup.

    Hi Jason, I tried that and that didn't work.

    I have a support case and am working on this but wondering if anyone has done this before.

    So far stopped the UIM Robot service.

    Removed all magic key line entries in the controller.cfg

    Copied the cfg to the changes directory.

    Deleted the controller.cfg, expire.* files from the robot directory.

    cleared out the niscache directory

    Started the UIM Robot and probes till come up as Invalidated.

    I recall there being something about moving the cfg file into the directory robot\changes or something like that.

    I tried this the other day and yes, move the controller.cfg file to the changes directory. Then delete the magic key tag for hte probes you are having issues with. Then restart the service. The controller.cfg file will be moved back to the proper location and update with the new keys.

    Hi there!

     

    What is the "changes" directory?

    Is the directory located here:

    C:\Program Files (x86)\Nimsoft\robot\changes

    It I think is a directory that the robot will use upon startup to validate the the changes made. Not 100% but to get things running if you made changes to a robot or probe outside the normal GUI's the changes have to be put in this dir if they started up and went RED. 

     

    If you have Auditing enabled there's a:

    C:\Program Files (x86)\Nimsoft\robot\cfgs  

    which tracks all changes made to probes and keeps a history of all the probe cfg changes.
