Cheshire Cat Computing

Hi,

My box run's mrtg-2.16.2, rrdtool-1.2.27 and perl-5.10.0. with Apache/2.0.52 (Red Hat) Server on kernel 2.6.9-42.ELsmp of RHEL 4 for routers2.cgi.

Kindly, can you guide me to get rid of the error as follows:

" Can't locate strict.pm in @INC (@INC contains: /home/lenin/localperl/lib/5.10.0/i686-linux /home/lenin/localperl/lib/5.10.0 /home/lenin/localperl/lib/site_perl/5.10.0/i686-linux /home/lenin/localperl/lib/site_perl/5.10.0 .) at /var/www/cgi-bin/routers2.cgi line 11.
[Sat Jun 21 17:12:21 2008] [error] [client 10.200.28.51] BEGIN failed--compilation aborted at /var/www/cgi-bin/routers2.cgi line 11 "
[Sat Jun 21 17:12:21 2008] [error] [client 10.200.28.51] Premature end of script headers: routers2.cgi
Note:But when i search for strict.pm it's availabe at '/home/lenin/localperl/lib/5.10.0 '

Also when i run routers2.cgi in shell i get the following error
"Global symbol "$APPMAIL" requires explicit package name at routers2.cgi line 1174.
Global symbol "$APPMAIL" requires explicit package name at routers2.cgi line 1224.
Execution of routers2.cgi aborted due to compilation errors"

Thanks in advance
Lenin

Perl 5.10 eh? I've never tested with this and it is possible that there is a syntax change.

Can you tell me which version of routers2 you are using? Check the comments at the beginning of this file to find this out if you don't already know.

The APMAIL definition comes right at the beginning of the script and is pretty clear. Its possible you have a corrupted script somehow.

I'd suggest that you check your routers2 script is the latest version and installed correctly, since the 'use strict;' is the first line and should work.

You might also like to check that you have SELinux disabled; this has been reported to cause problems with RRD-related CGI scripts (not just routers2) and might be at fault.

If I can get hold of a perl10 installation I'll see if there are any differences that would break things. I think it unlikely, though, as Perl has historically (since v5) been pretty good about maintaining backward compatibility.

Hi Steve,

Thank you for your reply and i appreciate of your support.

My routers2.cgi version is routers2-v2.18 and now i'm running on perl 5.8.8.
The mrtg *.cfg.ok has been creating succesfully (pls find logs) and .RRD database(pls find the logs) also been generating and my web browser is able to load '/cgi-bin/routers2.cgi' pge with twin menu view except 'graph in the center of the page'.

When i check the 'graphs path' nothing generated.

when i look in the '/var/lolg/httpd/error_log' the following's are displaying.

When search for the 'last.al' in my box it's not all there thouh i'm having perl 5.10.0 , rrdtool-1.2.27 ,mrtg-2.16.2 & mrtg-2.15.2 and routers2-v2.17a & routers2-v2.18.

Myself could not get any useful info over the google search fo r'last.al' and almost everybod's looking for the same.

Once again my thanking to you.

Regards,
LENIN

Looks like your RRDTool perl library is not installed correctly.

The Routers2 cannot generate the graph because it cannot access the RRDTool library, and the error message tells us that it has problems loading. The best solution to this is:

1) remove completely all the RRDs and RRDp directories under your perl path - ie, uninstall the RRDTool perl libraries.
find /usr/local/lib/perl5 -name 'RRD*' -exec rm {} \;
2) either
a) reinstall the RRDs perl libraries to your site_perl path, or
b) add the 'libadd' directive to your routers2.conf and MRTG .cfg files to point at the location of the RRDs.pm installation.

It looks like, during your switch between perls, something has beome confused.

Hi Steve,

Well, I Thank & welcome of your reply and it's appriciated.
myself worked in High-Performance Computing using IBM p595's & p690's in CMSD of 'University of Hyderabad' in India. http://cmsd.uohyd.ernet.in/

As you suggested removed and reinstall the RRD tool and recreated MRTG '.cfg' files and been creating RRD's database files.

Now in my browser other than 'graph' everthing's are seems OK.

please look in the following error.

"""""""""""""""""""""""""""""""""""""
No valid target is selected

You have no valid MRTG configuration files. You should check your configuration in /usr/local/etc/routers2.conf.
[/home/mrtg/cfg/*.cfg]

confpath = /home/mrtg/cfg

cfgfiles = *.cfg
"""""""""""""""""""""""""""""""""""""

Note: my mrtg .cfg file locatioon is " /home/mrtg/cfg/ " only.
I tried for almost everything.

Why it's says that ' no valid MRTG configuration files ' ?

Kindly can you post one working 'routers2.conf' file and the files acess pernission at " /var/www/"?

Once again thanking you
regards,
LENIN

The "No valid .cfg files" message means that Routers2 cannot find any MRTG configuration files matching the given pattern which contain valid Target definitions.

In your case, the pattern is /home/mrtg/cfg/*.cfg

Make sure you have files existing which match that pattern, and that they are readable by the web server user. If the filename is wrong, change the cfgfiles or confpath directives in the routers2.conf.

The routers2.conf file as shipped is a valid file. Really, only the cfgfiles, confpath, graphurl, graphpath and iconurl settings are required - everything else can default if necessary.

If you do have cfg files matching the pattern, and the files and the path to them are accessible by the web server user, then check the file has a valid Target[] line in in that is not commented out.

Your web server directory ( /var/www ) will probably have subdirectories cgi-bin (containing routers2.cgi) and htdocs (containing the graphs and rrdicons directories). The graphs directory must be writeable by the web server.

Since you can access the routers.cgi script, go to the configuration verification page by appending ?page=verify to the URL -- eg, http://yourserver/cgi-bin/routers2.cgi?page=verify -- and this will help to diagnose some common problems.

Hi Steve,

As you had instructed, checked/reinstall all and the following erron on my webserver error log.

Can't locate auto/RRDs/last.al in @INC (@INC contains: /usr/local/lib/perl5/5.8.8/i686-linux /usr/local/lib/perl5/5.8.8 /usr/local/lib/perl5/site_perl/5.8.8/i686-linux /usr/local/lib/perl5/site_perl/5.8.8 /usr/local/lib/perl5/site_perl .) at /var/www/cgi-bin/routers2.cgi line 7029

i searched for the 'last.sl' file and not all there in my unix box.

when browse with ' .routers2.cgi?page=verify the following error are there.

Script name : routers2.cgi (Version v2.18)

MRTG files
Path: /home/mrtg/cfg
Files: *.cfg : Directory does not exist or is not readable!

Perl libraries
RRDs, GD RRDs library NOT FOUND. This may however not be a problem if the library path is amended by the LibAdd birective in the MRTG files.
Can't load '/usr/local/lib/perl5/5.8.8/i686-linux/RRDs.so' for module RRDs: librrd.so.2: failed to map segment from shared object: Permission denied at /usr/local/lib/perl5/5.8.8/i686-linux/DynaLoader.pm line 230. at /var/www/cgi-bin/routers2.cgi line 8086 Compilation failed in require at /var/www/cgi-bin/routers2.cgi line 8086.
GD library not required as compact is disabled in routers.conf

Note: but mrtg cfg files are in /home/mrtg/cfg/ and it's globally readable.

please guige me to sort out this issue.

Thanks in advance.

regards,
LENIN
