perfSONAR User Q&A and Other Discussion

["Uhl, George D. (GSFC-423.0)[SGT INC]" <>]

On the centralized MA I installed the esmond-support branch of the
psTracerouteViewer code in the
/opt/perfsonar_ps/toolkit/web/root/gui/psTracerouteViewer/ directory.  I
modified the apache-maddash.conf file in /etc/httpd/conf.d and added the
following directive:

Alias /toolkit /opt/perfsonar_ps/toolkit/web/root
<Directory "/opt/perfsonar_ps/toolkit/web/root">
    Options FollowSymLinks -MultiViews +ExecCGI
    DirectoryIndex index.cgi index.php index.html
    AddHandler cgi-script .cgi .pl
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

I restarted the httpd and maddash-server daemons and when I try to view
the traceroute data I get a "500 Internal Service Error".  I checked
/var/log/httpd/error_log and it's telling me that I'm missing the MA.pm
script.

I installed a copy of MA.pm in
/opt/perfsonar_ps/toolkit/lib/perfSONAR_PS/Client/MA.pm but I'm still
getting a "500 Internal Service Error" with /var/log/httpd/error_log
