Hello everyone,
I'm trying to do a basic setup for GridFTP/Gram with Globus Toolkit
5.2.0. I have two Debian wheezy machines machines, alpha and bravo, that
communicate over a WAN.
I've setup SimpleCa and a myproxy server on alpha, and have distributed
certificates for users to bravo. I can login and retrieve credentials on
both machines without issue.
Gram works okay when going from bravo to alpha...
jon@bravo$ globus-job-run -a -r alpha
GRAM Authentication test successful
jon@bravo$ globus-job-run -verify alpha/jobmanager-fork /bin/hostname
Dryrun successful
alpha
jon@alpha$ globus -a -r bravo
GRAM Authentication test successful
jon@alpha$ globus-job-run -verify bravo/jobmanager-fork /bin/hostname =>
Dryrun successful
... but hangs indefinitely when submitting jobs from alpha to bravo.
GridFTP hangs for both machines.
Running the globus-url-copy command on bravo produces the following output:
$ globus-url-copy -vb -dbg gsiftp://alpha/etc/group file:///tmp/test-copy

And then the copy just hangs indefinitely. Same thing happens when I'm
on alpha and trying to copy from bravo.
The ephemeral ports are open for both alpha and bravo, so I know that
isn't it.
Any ideas as to what could be causing GridFTP/Gram to hang? Setting the
debug level to ALL on the grid ftp servers isn't producing anything helpful.
Thanks,
Jon
