check_iftraffic.pl plugin

[Alex Dehaini]

Thanks Marc,

I got the plug in from www.nagiosexchange.org, sorry I didn't specify that
earlier

I gave the traffic files in /tmp nagios group and user ownership and after
that, I ran the following command as the nagios user and this is the result
I got

nagios at snmp:/usr/local/nagios/libexec$ ./check_iftraffic.pl -H
41.211.0.42-C britania -i eth0 -b 100 -u m

I reckon this means that the plug in is working when ran from the nagios
plugin directory via the command line. However, the UNKNOWN error still
remains as reported from the the web cgi.

Am I missing something?
