perfSONAR User Q&A and Other Discussion

[Jochen Reinwand <>]

Hi Christian,

Looks like our CPAN modules have no dependencies for the required modules. Or 
have you seen any warnings about missing prerequisites during installation?

The missing module is Log::Dispatch. There should be an openSUSE package 
available called perl-Log-Dispatch.

The WebAdmin is also on the wiki page, but it is an Apache web page, not a 
CPAN style module. You have to copy it to the correct places of a running 
Apache web server. Most likely you don't want to do this. It is better to 
edit the configuration file by hand. It is a very easy to read and edit 
Apache style configuration file.

regards,
Jochen
