Greetings.

I'm trying to install routers2.cgi script and getting an Internal Server Error with 'Premature end of script headers' in apache logs, while trying to start http://bla.local/cgi-bin/mrtg/routers2.cgi?page=verify
What could it be?
Path to perl is ok.

Some configuration info:
mrtg-2.10.13p0
rrdtool-1.0.49
Apache/1.3.29 (running in chroot /var/www)
routers2-v2.16

Thanks in advance.

This error usually indicates a script failure.

I notice you have your script under /cgi-bin/mrtg/routers.cgi rather than the traditional /cgi-bin/routers.cgi, I trust you have added all the extra stuff to your apache config for this to work?

Also, look in your error log. This 'premature end' message will usually coincide with some more helpful error messages.

Try running it from the command line, and see what it says.

Check permissions. If you're chrooted, this may break such things as the perl path, or even library paths and other things. All paths specified in the config and so on will need to be relative to the chroot.
