| Post subject: | chroot path issues |
I just attempted to install routers2.cgi on an OpenBSD 4.0 box, but whenever I try to execute it I get an error in my apache logs saying: [Tue Jan 9 11:54:59 2007] [error] (2)No such file or directory: exec of /cgi-bin/routers2.cgi failed [Tue Jan 9 11:54:59 2007] [error] [client x.x.x.x] Premature end of script headers: /cgi-bin/routers2.cgi Looking at the routers2.cgi, I see that the first line is /usr/bin/perl. With Apache being chrooted to /var/www on OpenBSD, obviously it wouldn't be able to find this directory, thus explaining the error. How can I fix this? Thanks. |

Since the script is a Perl script, it will need access to both the Perl executable plus the Perl libraries. Also, it will need to be able to see the MRTG .cfg files and RRDTool .rrd files (if you have these under your www directory then this can be a security problem - you don't want people to be able to see the contents of the .cfg files over the web as they contain your SNMP community strings!) I think you will need to make a special copy of Perl and the libraries under the chroot path. |

hmmm- scratch that plan then. Is there any way to get it to run using Apache's mod_perl rather than calling perl directly? That would eliminate the issue, i would think... |

Yes, routers2 will run with mod_perl (and also with speedycgi as well) and will run much better as it will implement config caching for a big speed boost. Enable mod_perl as you would normally, and in the routers2.conf enable the 'cache=yes' line. This enables the extra caching. |

Ok, that sounds good, but then what would I need to change the first line to? As I understand things, running under mod_perl it shouldn't need to call the perl interpreter directly-apache should recognize it as a perl script and run it. Is this correct? Perhaps I just need to remove that first line? Or am I missing something? Thanks for the quick replies and assistance. |

I've never used mod_perl, but as I understand it, you dont need to change it although you may need to change the extension to .pl or something, or put it into a special directory with the mod_perl handler defined for it.... Probably your best path is to read the documentation for mod_perl...? |

Ok, after much head pounding and things tried, I have it working- at least initially. The frames load, but the main page gives an error. Since I believe this to be an unrelated issue, see my other post at http://www.steveshipway.org/forum/viewt ... =6881#6881 Thanks for the assistance. Israel |
