5 years ago That error, though woefully generic, is appropriate when the user is usr-md5-des and the privacy protocol is :aes. Changing the protocol to :des should work as expected.
However, you should know that there is no happy ending for AES. See the comments in #6 for the patch to fix the AES decoder bug in Erlang.

I run 'snmpget' command. It works well. But I run 'SNMP.get [1, 3, 6, 1, 2, 1, 1, 5, 0],"104.236.166.95",v3_cred', it return timeout. By Fix #6 ,I think 'snmp-elixir' had solved 'snmp get without engine-id' problem, isn't it?
