SNMP Enumeration (Simple Network Management Protocol)

Fix SNMP output values so they are human readable

apt-get install snmp-mibs-downloader download-mibs
echo "" > /etc/snmp/snmp.conf

Scanning for SNMP

Using nmap

root@kali:~# nmap -sU -v --open -p 161 192.168.1.12
   Note: SNMP is using UDP not TCP

Using onesixtyone

root@kali:~# echo public > /tmp/community.txt
root@kali:~# echo private >> /tmp/community.txt
root@kali:~# echo manager >> /tmp/community.txt
root@kali:~# echo 192.168.1.12 > /tmp/ip.txt
root@kali:~# onesixtyone -c /tmp/community.txt -i /tmp/ip.txt

Windows SNMP Enumeration Example

root@kali:~# snmpwalk -c puplic -v1 192.168.1.12
