[Swift-devel] OSG hang

[Michael Wilde]

Jack tells me you cant ping EC2 VMs form outside because they block ICMP.

Check with Jack on what you need to do (if anything) to make sure ports 50000 through 51000 are open, and then make sure GLOBUS_TCP_PORT_RANGE and GLOBUS_TCP_SOURCE_RANGE are set to 50000,51000

Then make sure (via say the nc or netcat commands) that you can connect to those ports from the OSG site.

If all that works, then work with Mihael to test a simple Karajan script that submits a job.  There are examples of these from Allan in /home/wilde/swift/lab/osg/allantools (or nearby there)
