perfSONAR User Q&A and Other Discussion

[Fausto Vetter <>]

Hi,

More information on this issue you can observe in: 
http://kb.pert.geant2.net/PERTKB/BwctlToolInfo

If the problem is firewall, try to define which port will be used by 
bwctl (iperf ports can be defined on bwctld.conf file / command line)

Any way, please let us know if you solve this issue.
