Asher, It doesn't sound to me as though you have any trouble understanding the concepts at all.
Check your firewall settings, though: http://dev.globus.org/wiki/FirewallHowTo It could be that the call-backs are not getting through. Also make sure you have the port ranges set up on each end properly. Alan (just another user!)

I have two different machines: a server machine and a client machine. I have installed: - Host certificate and user certificate in server machine - User certificate in client machine - Mapped the user certificate of the client machine in the gridmap of the server machine to the user of the server machine - Installed gridFTP server in the server machine and gridFTP client in the client machine (tested it works correctly with GSI) - Installed GRAM server/client and Jobmanager (fork) in the server machine and GRAM client in the client machine. In the client machine (10.211.55.9) if I try to connect to the server machine (20.211.55.5) the GRAM authentication test is successful: user1@grid:~$ globusrun -a -r 10.211.55.5:2119/jobmanager-fork GRAM Authentication test successful However, if I try to send a job it keeps waiting without any error and gives no output: user1@grid:~$ globus-job-run 10.211.55.5 /bin/echo Hello World If I use same command directly in the server machine it works fine and gives me the correct output: server@grid:~$ globus-job-run 10.211.55.5 /bin/echo Hello World Hello World What I'm doing wrong? I have searched everywhere but found no answer to this and I'm getting really desperate with it. Hope you can help me. Thank you very much.
