âšī¸ About TCP Port Checker
The TCP Port Checker is a diagnostic tool that tests if a remote server is accepting connections on a specific port. This is essential for verifying firewall rules, port-forwarding, and service availability.
đ How to use TCP Port Checker
- 1. Enter the domain or IP address of the server.
- 2. Enter the port number (e.g., 22 for SSH, 443 for HTTPS).
- 3. Click 'Run Tool' to attempt a TCP handshake.
- 4. A result of 'OPEN' means the service is reachable.
â Frequently Asked Questions
What does 'Filtered' mean?
It means the connection attempt timed out, usually because a firewall is silently dropping the packets.
Can I check multiple ports?
This tool checks one port at a time. For multiple ports, use our 'Port Scanner' tool.
