[mrtg-developers] FW: Problem executing external script

[Jaco Muller - MWeb]

Hi all,
 
I hope someone can help me with this. I have written a perl script that
does a snmp query, does some calculations and produces the values. When
I execute the script from the command line, it produces the output in
this format:
 
 
[root at netflow scripts]# perl
/home/networks/mrtg/scripts/vpdn_windhoek.pl
0
0
nodate
Windhoek VPDNs
 
However, when mrtg calls the exact same cript, it produces this error:
 
2003-11-28 13:58:00 -- Started mrtg
2003-11-28 13:58:02 -- WARNING: Could not get any data from external
command 'perl /home/networks/mrtg/scripts/vpdn_windhoek.pl'
Maybe the external command did not even start. (Illegal seek)
 
Mrtg is running as root on the machine and is executing a number of
other scripts with the same rights in the same directory, so it cannot
be a rights issue. Is it related to the way that mrtg interprets the
values being passed back from the scipt? Does anyone have any ideas what
else I can try?
 
Regards,
 
Jaco Muller
