Learn how to download and use Port Tester for a quick check of port access.
- [Instructor] Port Tester, written by Matteo Marquez Conway…is a simple but useful tool…for checking whether specific ports are open…for accessing a target URL.…This checks the pathway to the URL,…including any proxy or firewall…that might be positioned in front of it.…This tool can be downloaded from the site shown,…as a zip file containing a java JAR executable.…I have the Port Tester loaded on my Windows 7 system…so let's use it to look a the Meta Sploit server.…
The tool displays a window…in which we can enter URL and port numbers.…And it will run a very quick check to see if these are open.…Let's try port 53 on our Meta Sploit system.…I'll enter the IP and port number and press Test.…Okay.…We have a DNS service operating.…Let's put in a few more ports and test them.…And we quickly see which of these ports are open.…While we can do a full scan of a system,…this tool is useful when we have a very specific port…or set of ports to check on a firewall.…
