# SNMP SNMP runs on UDP 161. You can get information about a system from it. But you need to know the **community string** for it to give you a response. Brute forcing the community string: ``` onesixtyone -c /usr/share/metasploit-framework/data/wordlists/snmp-default-pass.txt ``` *Note: You will likely want to find a better wordlist.* Getting the data dump: ``` snmpwalk -Os -v1 -c > snmpout.txt ``` Flags: * `-v1` specifies SNMP version 1 This also gives some (but less) info: ``` Metasploit -> auxiliary/scanner/snmp/snmp_enum ``` Things to grep from the datadump: * `System uname` * `.1.3.6.1.2.1.1.1.0` - [System's hardware type, software operating-system, and networking software.](https://oidref.com/1.3.6.1.2.1.1.1) * `trap` - To find other community strings (under "traphost") * `fail` - Finding failed login attempts from logs (telnet or ssh for example, not all devices log these login attempts but some do). Getting ipv6 addresses (if any) from the data dump: ``` python enyx.py version communitystring IP ``` {% embed url="" %} Unique local (Link Local/Local Unicast) is probably the output you’re looking for. It will return loopback as well afaik. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
