Challenges completed
Complete TryHackMe basic port scan room
What I learned
- TCP Flags
- TCP Connect Scans
- TCP SYN Scan
- UDP Scan
Commands, tools, and techniques
- TCP Connect Scan - nmap -sT 10.146.169.240
- TCP SYN Scan - sudo nmap -sS 10.146.169.240
- UDP Scan - sudo nmap -sU 10.146.169.240
- -p- : all ports
- -p1-1023 : scan ports 1 to 1023
- -F : 100 most common ports
- -r : scan ports in consecutive order
- -T<0-5> : T0 being the slowest and T5 the fastest
- —max-rate 50 : rate <= 50 packets/sec
- —min-rate 15 : rate >= 15 packets/sec
- —min-parallelism 100 : at least 100 probes in parallel
Problems and dead ends
Explain what did not work and why.
What I will revisit
List anything that needs more practice or a second attempt.
