perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

Does the message about /etc/hosts persist or is it now just the "Problem 
reading testing configuration: Problem reading perfSONAR-BUOY Configuration" 
message? Could you send me the contents of /etc/hosts and 
/opt/perfsonar_ps/perfsonarbuoy_ma/etc/owmesh.conf?

Thanks,
Andy
