Hello Rolf,

Have you tried running bandwidth measurements from the CLI?

When I try running a throughput test to your host it runs fine, however the 
same test from your host to mine fails. Can you try running some `pscheduler 
task throughput —dest some.server` and also have a look at some log files 
like:

/var/log/pscheduler/pscheduler.log
/var/log/httpd/error_log

You should also check the pscheduler services are running, you can find the 
needed information at http://docs.perfsonar.net/pscheduler_server_running.html

Checking the pscheduler schedule might also help: 
http://docs.perfsonar.net/pscheduler_client_schedule.html

Let us know what you find.

Antoine.
