- Conduct a full UDP port scan (may be all `open|filtered`) because open ports rarely respond to empty probes. No response --> open port or dropped by firewall.
```
nmap -A -sV -sC -sU 10.11.1.111 --script=*enum --top-ports 20
```
- When version scanning is enabled with -sV (or -A), it will send UDP probes to every `open|filtered` port. If any of the probes elicit a response from an `open|filtered`port, the state is changed to open.

- Nmap scripts location `/usr/share/nmap/scripts/`
```
proxychains nmap --top-ports=20 -sT -Pn 10.5.5.20
```
- SOCKS proxies require a TCP connection to be made and thus a half-open or SYN scan cannot be used with ProxyChains
Scans thru Socks proxy
```
nmap --proxies socks4://proxy-ip:8080 target-ip
