Ok Thank you.

All problems about firewall and ports are solved I can run my job now.

One problem was that BioLinux containing UFW system (Uncomplicated FireWall) 
and it has rather complicated things because there's a default rules that is 
not good that block communicaion of HTCondor. 

So now I'm going to find a solution to limit the memory use of desktop 
machines to avoid their crashes.

Goodbye. Have a nice day.
