**Lists all SNMP-related nmap scripts:**

```
ls -l /usr/share/nmap/script | grep -i snmp
```

**Obtains SNMP info at specified OID:**

```
snmpwalk -c <c_string> -v <version> <target> <OID>
```

**Changes the SNMP information at specified OID:**

```
snmpset -c <c_string> -v <version> <target> <OID> <value_type> <value>
```

**Onesixtyone brute force:**

```
echo public > community
echo private >> community
echo manager >> community
onesixtyone -c community <target>
```

**Enumerate system processes:**

```
snmpwalk -c <community string> -<version> <target> 1.3.6.1.2.1.25.1.6.0

snmpwalk -c <community string> -<version> <target> 1.3.6.1.2.1.6.13.1.3
```

### SNMP and Metaespoit

```
msf > use auxiliary/scanner/snmp/snmp_login
msf > set PASSWORD public
msf > set RHOSTS file:snmp.txt
msf > set THREADS 25
msf > set VERBOSE false
msf > set VERSION 2c
msf > run
```

### NFS Enumeration

Discover rpcbind:

```
$ sudo nmap -sV --script rpcinfo 10.10.13.37 -p111
```

Run Nmap scripts:

```
$ sudo nmap -sV --script 'nfs*' 10.10.13.37 -p2049
```

## Mount

```
$ showmount -e 10.10.13.37
