TCP vs UDP
TCP:
- Connection-oriented
- Suited for applications that require high reliablity[HTTP, FTP,Telnet]
- Three-way handshake
UDP:
- Connectionless
- Suited for applications that need fast connection[DNS, DHCP, SNMP]
- No handshake
Scanning with Nmap
Example:
- nmap -sn -oN /root/sweep.txt 10.0.0.0/24
- nmap -vv -Pn -A -sS -T4 -p- -oN /root/scan1.txt 10.0.0.15
- namp -vv -Pn -A -sU -T4 --top-ports 200 -oN /root/udpscan.txt 10.0.0.15
- namp -Pn --top-ports 1000 -sU --stats-every 3m --max-retries 1 -T3 -oN /root/udpscan2.txt 10.0.0.15
- nmap -vv -p 137 --script=all 10.0.0.15
