SET string and integer scalars
++++++++++++++++++++++++++++++
Send SNMP SET request with the following options:
* with SNMPv1 with community name 'private'
* over IPv4/UDP
* to an Agent at 104.236.166.95:161
* for OIDs in tuple form and an integer and string-typed values
This script performs similar to the following Net-SNMP command:
| $ snmpset -v1 -c private -ObentU 104.236.166.95:161 1.3.6.1.2.1.1.9.1.3.1 s 'my value' 1.3.6.1.2.1.1.9.1.4.1 t 123
