MG-SOFT SNMP Master Agent
(simultaneously supporting SNMPv1, SNMPv2c and SNMPv3 protocols)

Monet Logo MG-SOFT SNMP Agent is a transparent replacement for the SNMP service running on Windows 95, Windows 98, Windows ME, Windows NT, Windows 2000 or Windows XP operating systems. Transparent means that no changes whatsoever are required in the existing subagents and in the master agent configuration. To deploy the MG-SOFT SNMP Master Agent, you only need to shutdown Microsoft's SNMP Master Agent (service) and start MG-SOFT's SNMP Master Agent. While starting, MG-SOFT SNMP Master Agent reads Microsoft agent's configuration parameters from the system registry and loads the listed subagent DLLs.

When running, MG-SOFT's SNMP Master Agent will properly respond also to received SNMPv2c and SNMPv3 requests. By default, the SNMPv3 protocol is configured to run in the noAuth/noPriv mode. However, by adding a few additional registry keys, you can configure it to run in any other SNMPv3 security mode.

Secure replacement for the SNMP service on Windows
If you configure MG-SOFT's SNMP Master Agent to respond only to SNMPv3 protocol queries, you significantly improve the overall security of the computer running MG-SOFT's SNMP agent. The SNMPv3 protocol implements strong authentication and network packet encryption, so that malicious visitors cannot actively reconfigure the computer running the SNMP agent, nor can they view the contents of SNMP network packets (if they somehow manage to sniff them from the network).

Subagents are completely un-related to the SNMP version spoken by the master agent and they don't require any modifications when the SNMP protocol version in the master agent is changed. There is no need for any modification in the existing extension DLLs, i.e., the same binaries that are used with Microsoft's agent will run also with MG-SOFT's agent.

For example, MG-SOFT's agent provided on the Internet for the SNMPv3 interoperability testing is running on an NT 4.0 machine and is using the standard Microsoft's inetmib1.dll extension dll, binary file distributed with various versions of 32-bit windows OSes (i.e., MG-SOFT doesn't have source code for the extension dll to change or re-compile it. It runs with MG-SOFT's SNMP Master Agent just as Microsoft provided it).

The advantage of Microsoft's SNMP Master Agent (vs. plain WinSNMP SNMP Master Agent solution) is that Microsoft supports the RFC1213 MIB and some other subagents (if you go with plain WinSNMP solution, you need to implement them by yourself). The advantage of MG-SOFT's SNMP Master Agent (vs. Microsoft's SNMP Master Agent) is that MG-SOFT's supports SNMPv1, SNMPv2c and SNMPv3, while Microsoft's SNMP Master Agent supports only SNMPv1.
