installing net-snmp with V3 support on windows to use as mgmt tool for making requests to remote systems

I am trying to make an snmpget request on a Windows 10 system to a system that only has SNMPv3 enabled.

I have installed net-snmp-5.7.0-1.x86.exe onto Windows 10. During the installation, I check the "Encryption Support" checkbox. It states "OpenSSL does not appear to be installed..." even though I have it installed. Possibly to a different path. I continue to install. An snmpget -v2c requests works ok, but V3 fails: Error in packet Reason: authorizationError (access denied to that object)

Other proprietary tools have worked, so the remote system is fine. I need to provide steps to others on how to get V3 requests to work on multiple systems and don't want to build from the source code. I would like to get it working with open source tools.

Does anyone know how to get net-snmp to work with V3 with just running installers?

The closest I could find was this older link using older versions: https://sourceforge.net/p/net-snmp/bugs/2703/

They were able to get an older net-snmp,net-snmp-5.5.0 installer x64 version. https://sourceforge.net/projects/net-snmp/files/net-snmp%20binaries/5.5-binaries/net-snmp-5.5.0-2.x64.exe/download

With an older Microsoft Visual C++ 2008 Redistributable https://www.microsoft.com/en-us/download/details.aspx?id=11895

With an older ActivePerl-5.22

With an older Win64OpenSSL-0_9_8y https://archives.darenet.org/misc/openssl-bin/Win32OpenSSL_Light-0_9_8y.exe

But when I tried to follow those steps, I just got a crash dialog when running an snmpget.

NET-SNMP stops producing its Windows builds years ago, so you shouldn't expect anything to work. The old installers depend on very old OpenSSL bits, so you shouldn't use them either. If you do want to run SNMP v3 agent on Windows, you need to support yourself by compiling/modifying NET-SNMP source code, or find free/commercial alternatives.

You should post and accept your answer. That's how this site works.

Thanks Lex, good to know it's not possible with net-snmp. I didn't see anything that stated that on the net-snmp site.

In case anyone is looking for an alternative to net-snmp I found:
SNMPSoft’s snmpget. ezfive.com/snmpsoft-tools/snmp-get
Quick to install and easy to use.

Example:
SnmpGet.exe -r:"10.24.85.113" -v:3 -sn:admin -ap:MD5 -aw:11111111 -pp:DES -pw:11111111 -o:.1.3.6.1.2.1.1.1.0

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
