SNMP

161/UDP

In SNMP versions 1 and 2c, access is controlled using a plaintext community string, and if we know the name, we can gain access to it. Encryption and authentication were only added in SNMP version 3.

[!NOTE] Community（不是密码）似乎是相当于域的东西，在这个域范围内共享信息 默认值： - public：read用 - private：读写用

工具

snmpwalk

snmpwalk -v 2c -c public 10.129.42.253 1.3.6.1.2.1.1.5.0

- 这里的public即Community
