Lightsquid Graph 500 Server Error Resolution

  • C

    Hi All

    I recently updated my Firewalls to the latest release of pfSense 2.0.2. Once the update was completed and the packages had been re-installed I ran into the issue where the Lightsquid graphs were no longer working and I instead was getting a "Server 500 Error". I have encountered this error before and had to do the research twice to fix it so here is a quick resolution so that I can easily find it again if I need to.

    SSH as root to the firewall and go to

    cd /usr/local/www/lightsquid

    Then run the lightsquid check which will check for all the lightsquid dependencies

    ./check-setup.pl

    If this command throws an error then you will need to install perl which can be done with the following command:

    pkg_add -rvf ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.2-release/Latest/perl.tbz

    Try running the check-setup command again. If you still encounter errors you may need to resolve the links from /usr/bin to /usr/local/bin
    Here are the commands to do so: (Note: the version numbers on your system may be different to those stated below)

    
ln -s /usr/local/bin/perl5.14.2 /usr/bin/perl
ln -s /usr/local/bin/perl5.14.2 /usr/bin/perl5

    You may also need to update the perl5 link in /usr/local/bin

    
ln -s /usr/local/bin/perl5.14.2 /usr/local/bin/perl5

    When the check-setup command is runs you will likely encounter the output error: "no: GD.PM found, please install or set $graphreport=0 to disable"
    To resolve this we will need to install the p5-GD libraries. Use the command below to do so

    pkg_add -rvf ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.2-release/Latest/p5-GD.tbz

    Run the check-setup command after the install completes and you should get an output similar to:

all check passed, now try access to cgi part in browser

    Your graphs should now work correctly.

    NOTE: On one of the firewalls I configured I had to re-run the install for perl library and dependencies again before the system picked up the missing library.

    I encounter the "no gd.pm found" error but when i run the pkg_info it states that i do have it installed.

    What should I do?

    Great tutorial btw

    It is likely that your links are not in the right place but I'd need more info to go on in order to help more. eg. pkg_info output etc.

    Your other option is to run the command

    
pkg_add -rvf ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.2-release/Latest/p5-GD.tbz

    Which will forcefully install the p5-GD package and dependencies again, hopefully repairing the links.

    I will try your suggestion to reinstall p5-GD package

    Confirmed. That first post in this thread fixed the problems. I'm latest build 2.1.
    Had to reload / refresh browser though (Ctrl+R  / F5) to get the graphs to show.

    Try to remove all that and remove lightsquid as well and reinstall.

    I changed the build options on the PBI to ensure that it includes perl and GD. If that alone isn't enough, then the install code may need to make some additional symlinks and such.

    Hi Jimp,

    When I execute per graph.cgi from the shell it come out like this:

     perl graph.cgi
Can't load '/usr/local/lib/perl5/site_perl/5.12.4/mach/auto/GD/GD.so' for module GD: /usr/local/lib/perl5/site_perl/5.12.4/mach/auto/GD/GD.so: Undefined symbol "PL_sv_undef" at /usr/local/lib/perl5/5.12.4/mach/DynaLoader.pm line 200.
 at graph.cgi line 23
Compilation failed in require at graph.cgi line 23.
BEGIN failed--compilation aborted at graph.cgi line 23.

    I even tried uninstalling all packages and try almost every install sequence but still having this error.

    For the record, the lightsquid graph is the only thing not working in my setup. Everything else is just perfect.

    Hey Jimp

    I tested your changes, by uninstalling and re-installing lightsquid the problem appears to resolve itself.

    Thanks bud  :)

    So it does… with one exception. If you install git (for gitsync) before lightsquid, git's perl install doesn't have GD so it won't find it.

    But if you uninstall git, remove/reinstall lightsquid, then it works.

    Please note that the perl package location has changed.

    Use to update link:

    
pkg_add -rvf ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8-stable/Latest/perl.tbz
