can't get nk-snmp-deviceinfo to work

[itchykun]

Hi,

Thank you for writing this useful tool. However, I can't get nk-snmp-deviceinfo to work properly. I installed it without error but when I tried to use it against my SNMPv3 device (Arista, Cisco, Junos, doesn't matter), I get the same error every time.

lab$ nk-snmp-deviceinfo -H hostname -P 3 -L authPriv -a SHA -X AES -U v3PDTuser -A pass_auth -X pass_priv
