perfSONAR User Q&A and Other Discussion

[Maciej Glowiak <>]

Hi Vlada,

I tested it mostly as root user, that's right. I made some small fixes 
and now it should work fine. I didn't encounter your second problem 
("Use a fileset"); maybe it's because of ant version? I suppose you have 
the newest one. I used ant 1.6.5.

It is called "release candidate" because it's still in testing. If 
everything were ok, it would be called just a "release". Thanks for your 
comments.

Please download RC2:

http://wiki.perfsonar.net/images/files/perfSONAR-XML-LS-1.1-RC1.tar.gz

I fixed some more problems, so it should be ok now.

Best regards
and thanks for you input,

Maciej Glowiak
