The Port Scanner checks a host for open common ports, revealing which services such as HTTP, HTTPS, SSH, FTP and mail are exposed and reachable from the internet. Every open port is a potential door into a server, so knowing which are open helps you confirm that intended services are running and, just as importantly, that unnecessary ones are closed. It is a quick way to audit a server's external footprint without installing anything.
Aimed at developers, administrators, and security-conscious owners in Cambodia and beyond, this free tool by Hosting Cambodia scans a target and reports each common port's status in plain terms. Use it to verify a newly configured web or mail server is listening correctly, to spot risky services left exposed, or to double-check a firewall change did what you expected.
Frequently asked questions
Which ports does the scanner check?
It scans common well-known ports for services like HTTP (80), HTTPS (443), SSH (22), FTP (21), and mail ports, so you can quickly see which standard services are exposed.
What does an open port mean?
An open port means a service is listening and reachable at that address. That is expected for services you run publicly, but unexpected open ports can indicate a misconfiguration or security risk.
Is it legal to scan a server's ports?
Scanning servers you own or have permission to test is fine. Scanning systems you do not control may violate acceptable-use policies, so only scan hosts you are authorised to assess.
