About this tool
Check which common TCP ports on a public host accept connections, with a full exposure report.
XGM opens a TCP connection to each port you list from its server (1.5 s timeout, up to 200 ports). On open ports it reads the greeting that SSH, SMTP, FTP, POP3, IMAP and MySQL servers send on their own, and sends a single HEAD / request to HTTP and HTTPS ports to read the status line and Server header. It does not log in, send other data or probe for vulnerabilities. The service name comes from that banner, otherwise it is a guess from the port number.
How to use it
- Open the Port Scanner tool.
- Enter the public domain, hostname or IP address you want to check.
- Run the check; XGM queries it from its server and lists the findings.
- Copy the output only after checking it looks correct.
- Use related XGM tools if you need a broader diagnostic view.
