Port Scanner / Sniffer

Every computer protocol, such as HTTP, FTP, or SMTP, that utilizes an internet connection communicates using a unique port number. This port must be open in both the sending and receiving machine for the connection to work. This tool scans either your own network / computer / server or an external hostname that you specify. The results will help you troubleshoot your networks and configure your computers accordingly.

Running any of the port scanners may take up to 60 seconds, be patient.

Basic Test / Server Ports Checks many popular server ports	Common Applications Checks ports used by many popular internet applications
P2P File Sharing Checks ports for many popular P2P protocols	PC Games Check many common pc game ports

Custom Port Test

Scan External Domain	Scan Yourself
: Enter a valid port #	38.107.179.240: Enter a valid port #

The Internet Assigned Numbers Authority (IANA) compiles a list of all internet protocols and the ports that they use. This can be helpful when trying to identify an unknown port or protocol.

Download & View Source Code

UberPC.org fully supports open source software. The source code for the Port Scanner Tools can be download here along with their joomla components. All code is written in PHP version 5. Click "View Source" to see how it works.

Due to the complexity of the port scanner code, downloading all the files is required for it to function properly.
