Tools: Network Tools

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!

 

Tools: Color Bandwidth Monitor

We’ve mentioned a few networking tools in the past, and today we’ll look at really handy one.

The tool is called The Color Bandwidth Monitor and it is a very small, Terminal program that will give you a quick graphical output of your network throughput.

Head over to your Package Manager, and search for CBM:

Of course, if you wish, you can also install it from a Terminal window by simply typing:

sudo apt-get install cbm

Once installed, simply open a new Terminal window, and type: cbm

which will then fire up a terminal based GUI, showing what’s going on with your network adapters.

The real power of this utility for me, is that because it runs inside the terminal window; you can use it on a remote machine, by logging in with ssh.

Once logged in, you can first install it if you need to, and then see what’s happening with that machines network adapters.
