[SOLVED]Cacti 1.2.18 vs. cacti 1.2.16 and ping for availability

[eholz1]

Hello Members,
I know there is a much older thread that "almost" addresses this issue - Yes spine is setuid, etc\

I have this issue with cacti-1.2.18 - if snmp is not used, and ping used for device availability
the device shows as down, but the ICMP ping is good and received. If I can enable snmp on the device - then it will show as UP if I use "Ping or SNMP"

In cacti 1.2.16 if snmp is not used - set to "none" and ping is used - the device shows as UP.

What is the difference between these two versions of cacti?

Or -- what am I missing?

Thanks,
