Kportscan 30 Full

Regulatory frameworks often require that you prove no unnecessary ports are open. You cannot prove a negative with a top-1000 scan. A full port scan (1-65535) with a generous timeout (30 seconds) ensures that no high-numbered, hidden backdoor port remains undetected.

If you need the depth of a full scan but are worried about time, combine the 30 timeout with the --rate parameter:

sudo kportscan 30 full --rate 10000 192.168.1.1

This sends 10,000 packets per second while still waiting 30 seconds for each distinct retransmission. This can reduce a full scan from 18 minutes to under 2 minutes on a gigabit network. kportscan 30 full

Based on the full scan output and service mapping:

Before running complex tools like Nessus or OpenVAS, security teams use kportscan 30 full to perform a "quick win" scan. Identifying open SMB ports (445) or RDP (3389) immediately highlights high-risk targets. Regulatory frameworks often require that you prove no

A successful run will produce output similar to this:

[+] Starting kportscan v2.3 (timeout: 30s, mode: full)
[+] Target: 203.0.113.55
[+] Scanning 65535 ports...
[+] Port 22/tcp open (SSH - 30.2ms response)
[+] Port 80/tcp open (HTTP - 12.1ms)
[+] Port 443/tcp open (HTTPS - 15.7ms)
[+] Port 3389/tcp open (RDP - 1400.3ms response - SLOW)
[+] Port 49152/tcp open (Windows RPC - 28.1ms)
[+] Scan complete. 5 open ports found. Time elapsed: 18 minutes 43 seconds.

Key insights from this output:

Solution: A local firewall (Windows Defender Firewall) may be dropping ICMP packets. Disable "Block ICMP" temporarily, or change the scan method to "TCP Connect" with a longer timeout (2000ms).
