check_snmp and timeout]

[Fredrik Wänglund]

OK, 10.20.30.40 is a non-existing host just to show how it looks when 
check_snmp times out.
What I wanted to show was that regardless of whether i have '-t 30' or 
not the plugin exits
after 6 seconds with the message;

SNMP problem - No data recieved from host
CMD: /usr/bin/snmpget -m NONE -v 1 -c abc 10.20.30.40:161  1.2

If the CMD:... is the complete commandline the plugin calls, then it 
look like
the timeoutvalue is simply ignored by the plugin.
