There are many linux boxes in DMZ. They cannot submit their output back to the OA server. Is there any way to submit the script output back via existing ssh connection? (Port forwarding, tunneling...)
For environments like this we suggest upgrading to an Enterprise license and then placing a collector server inside the DMZ. We just recently had a webinar on this topic that should help clear up any of your questions.
