Hi Ged,

Sorry about that.  I didn't realize I was just replying to you only. :)

I was referring to the ./etc/config file in the Smokeping package.  This is what I have setup for it.  [Just a note, but I have tried changing the cgiurl = htpp://hppav.proxima.local/cgi-bin/smokeping.cgi with no improvement if at all any].

The NTP clock is setup for the one we use here at work.

[root at hppav etc]# cat ntp.conf | grep -i server

At 14:00, with Mozilla, I tried accessing http://hppav.proxima.local/cgi-bin/smokeping.cgi and I received the Error 500 Internal Server Error (all in text not HTML).  When I tried to access http://hppav.proxima.local/cgi-bin/smokeping.cgi at 14:02 (with IE) at 14:02, I get page cannot be displayed.

Here are my access/error logs:

I don't understand this step (from http://oss.oetiker.ch/smokeping/doc/smokeping_install.en.html):

To make the interactive graph-zoomer work, you have to place the content of the cropper directory somewhere on your webserver and adapt the links in basepage.html (see below)."

It says "see below" but nothing is listed.


If you are using a version of Perl older than 5.8.1, you should consider installing a newer version of CGI::Carp (must be at least 1.24, included in CGI.pm-2.82). Otherwise any error messages generated by the CGI script will not show up quite as clean as they could in the web server error log. If you can't or don't want to upgrade CGI::Carp, you can also set the changecgiprogramname variable in the General section to the value no."

The link is broken, and I don't know if I need this based upon what I've been corresponding with.


Well I wont get much into this. The important thing is, to have a webserver which allows you to run CGI scripts. If you are using Apache I strongly recommend using the suexec system for running CGI scripts. Often it is sufficient to change the suexec binary to setuid root and restart Apache. Using suexec allow to run cgi scripts under proper user accounts."

I added a Virtual Host to the httpd.conf, the user/group that it uses is "apache."  All the defaults were listed.  Do you want to see that file?  I'm not sure how to use suexec.  Maybe that's what I need to do to make this work.

Thank you again for your enduring patience with me....:)
