I installed the pre-req for Net::SNMP, but when running "./check_ifstatus -h
" command, show me :
****************************************************************************
**********************************************
[root at monitor libexec]# ./check_ifstatus -h

status of each network interface (except PPP interfaces) on the target host

Why seem the message "Use of uninitialized value in concatenation (.) or

?

Thank you.
