Network hack

[silenthunder]

The school has put a military-grade security system on our network, and the only way I can see to get an outside machine inside it is by plugging into a school's machine and checking "allow other computers to gain internet access through this computer".
 
Would doing so give me inside access to the network and the possibility of breaking into the main server and crippling the network security software?
 
I want to do this for me, and I have no intentions of doing anything after getting wi-fi access on my laptop.

I believe that sharing a connection won't put you in the same network, but instead will put you inside a different network shared with the host machine, which will forward your packets to the actual network (I'm not sure it works like this, but from my last tests it seems so).

A better way to put your computer in the same network would be to (in windows) select both network adapters (the one connected to the network and the one connected to your computer), right clicking them and selecting "Bridge Connections". This will put you inside the same network as the computer you're connected to, and allow you to request an IP address through DHCP.

Right, I meant to say bridge the connections. On windows 8 it doesn't exactly work like that, but the option is still there. However, if I were to bridge the connections, wouldn't that put me directly in the network? The security system on this network is set up to block anything that tries to connect to the network at all. My laptop will say connected, but there's no internet access, no network access or options, I can't even view what else is on the network. So I figured that I could give myself internet connection through a computer and then backtrack back into the network or some theory like that..

Yes, bridging the connections will put you directly in the network. They could be using MAC address based DHCP rules or a RADIUS server. First one is easy to bypass, just change your MAC address to one that is accepted. As for the second one, I can't see a way to bypass that.

Great idea, I'll spoof my mac address. That makes so much sense that I'm almost 100% sure that's what the security software is doing.

Happend to me dat i was connected but had no network and internet access. So manually changed the settings, since i knew the DNS server, i manually put in another ip, changed mac adress and i was in.

Well seeing as this is a tested theory >.> now only to secure the necessary time..
