Is the passtest script being run? Can you verify this by modifying it
to write to a log file somewhere?

1. If it is not being run, check the permissions in snmpd.conf. You'll
need some combination of com2sec/group/view that allows access to the
OID subtree.

2. If it is being run, what is it printing on stdout? Please run it
manually and paste the output in a reply.
e.g.
./passtest -g .1.3.6.1.4.1.8072.2.255.1.0

According to the snmpd.conf man-page, it should print just three lines
and then exit:
oid
type
value

The oid should be that passed in. The type should be one of: integer,
gauge, counter, timeticks, ipaddress, objectid, string.

What snmp command are you using to test snmpd? Please show command line.
