temperature.sh reports Unknown OS

Hello all

I've been trying for a while to find a solution in the archives but i wasn't able, so here's the problem:

I have 2 Dell PE 1850 servers running CentOS with hobbit client installed. I want to monitor the clients using omreport sending the results to Hobbit server. I am trying as a start to check the temperature using the temperature.sh script from deadcat. When i try to run it, it returns Unknown OS. Then i tried to run openmanage.sh and it reports omreport command not found. I am using Administrators Version 6.4

Any ideas?

Thanks!
