  This probably has nothing at all to do with net-snmp, but has
everything to do with the socket library in the system you're trying to
use to broadcast UDP packets.  It is fairly common to deny access to the
universal broadcast address, even when running as root.

  An alternative you might try is to derive your individual IP network
broadcast address and see if that works.  This can be determined
programmatically if need be, if you're running a Linux system try the
"ifconfig" command.

  Given your working example of 10.0.0.5, if using a subnet mask of
255.255.255.0, try the snmpget command to 10.0.0.255.
