Run a snmpwalk against your system's full tree and count the lines
just to verify that it's wide open

snmpwalk -v1 -c public localhost .1 | wc -l

One of my systems returns over 4500 lines, if yours is returning
a small amount(few dozen) then security is too tight for the
community string your using and you need to adjust snmpd.conf

See this as an example:
