Did you know, when you want to look up the owner of a web site, you don’t need to head right to the web to do it! There is a tool included in your Linux Mint and most other distributions that gives you several useful tools in a single place.
Head to your Menu, and in System Tools, you will find the program called Network Tools
I use it a lot, to see who owns a web site. It’s simple to use, just enter the web site name, and push enter!
You can of course, also get information about your own connections, be they wired or wireless:
Routing tables, trace routes, and the ability to finger another site are also possible.
My favorite tool though, is the port scanner. Port scanning, allows you to see what ports are open on any machine on your network, or on the Internet.
Where I really use it though, is when I find a hacker scanning incoming ports on my incoming firewall, trying to find open computers to hack. By port scanning them back, they usually stop their attack pretty fast when they realize I can play that game too!
