Introduction

You will need working knowledge of Simple Network Management Protocol (SNMP).md) in order to follow through.

SNMP Enumeration using snmp-check

snmp-check is a simple utility for basic SNMP enumeration. You only need to provide it with the IP address to enumerate:

snmp-check [IP]

Furthermore, you have the following command-line options:

  • -p: Change the port to enumerate. Default is 161.
