SNMP Enumeration

Simple Network Management Protocol (SNMP) is used for remote monitoring and managing of hosts, routers, switches or any device connected to network. SNMP works on 161/UDP, SNMP Trap on 162/UDP. By default SNMP comes with two community (username) strings
            public (read only access)
            private (read write access)

We will discuss about SNScan from foundstone.com to Scan for Devices which are running SNMP service. You can mention a particular IP Address or range of IP Addresses to scan.




Management Information Base (MIB) describes all network objects that can be monitored and managed using SNMP. MIB’s are accessed using Object Identifiers (OID’s)

net-snmp utilities on Linux distributions already have few snmp commands.

We need to provide password list file which contains  expected passwords. SNScan tried thos passwords against public and private community strings, successful hit will give the community string-password for a particular host.
