No I was not aware of that. But security is not a major factor here, is it?

Also as for that example you just gave, no fucking idea what it is. I am a newcomer to networking, still studying it.

But do you not agree using a VPN would be "easier"?

Yeah proxx said prett much everything, do you even obtain a local IP from the DHCP server? If not try to assign a static one... Worked for me once!  I'll check back here when there is something more to go on

Pretty much what DarkVision said... What Kernel are you using? I know for a fact that that plays a very big part in root exploits.

I am not sure I understand what you're asking. A MAC address is a unique address or "identifier" assigned to your network device when it is in production.

But when you're on a network, such as your home network or school network, for packets etc to travel to their destination they need to know where to go, so they find their destination essentially through IP address.

The way it works is:

You, the client connect to the network.
You request an IP address from the router
Router gives you an IP address and stores what MAC address is assigned to that IP address
When data comes through that is destined to you, it checks it up with the router and sees what MAC address is asgined to your IP. Data delivered!

There are many ways to essentially "change" or "spoof" your MAC address. As always Google is your friend for such tools, I use "mac changer".
