What is this?

This is a simple bash script that queries QNAP web address in order to:

• Determine the current status of the SNMP Service (0=disable/stopped, 1=enabled/started)
• Enable/Start SNMP Service
• Disable/Stop SNMP Service

I needed to create this due to what appears to be a bug with QNAP's snmp service where each time a SNMP query is sent, the query time takes long and longer and longer. Eventually the SNMP service will take so long it times out before returning any results. Restarting the SNMP service addresses this.
