Is it possible to block ip addresses?

[yoda]

I was wondering if anyone knew if you could block ip addresses because at my school people hack beyond belief while i try to do work, and the windows firewall is off by default and we can't change any of that. So i was wondering if any knew of freeware software or anything really that help me block ip addresses?

Thanks for your time Yoda :)

Hey, Yoda,
I hope i'm understanding your question correctly and might I suggest using an anonymous proxy. Some are free on the net and should be ok for temporary use. It really depends on what type of intrusion your experiencing.

HTH,

well i want to block local IP addresses so with in the LAN at my school. Just so they can't run programs namely hacking programs like psexec and so forth, so if that program connects to my computer from another computer that it will block that program from accessing my computer, and not complete the connection between my computer and theirs.

[MindBender77]

I see. Then you might want to try ZoneAlarm Firewall.

Hope this Helps,
Bender

If you don't actually require network access yourself you could always just unplug the network cable.

[yoda]

True, but i do have to access are network cause logins are on a server and so are are files, so not really an option lol but thanks anyways :)

another option is netcat you might be able to redirect connections to your computer elsewhere.

[yoda]

please explain netcat :) if you have the time thank you :)

Nvm i looked up Netcat and by the looks of it it seems like its only for linux am i wrong??

Yoda :)

[Banfa]

yes google "netcat for windows"

[yoda]

You could always just stick a router between your computer and the local network.

[yoda]

true but i can't because if i do that the teacher will question me why i carry a router around school :P and it probly requires you set it up everytime which i don't have, but good suggetion :)

Yoda

Ah, then it's not your own computer that you are using, but one that belongs to the school. If they are not enabling the windows firewall then they probally won't allow you to install your own firewall on the computers. You might want to google to see if there are any USB / U3 based personal firewalls available.

[yoda]

yea it belongs to the school, and yes the firewall can't be enabled, and we can install software but the school has deepfreeze which cleans all unwanted software you installed on the computer, okay thanks for the suggestion :) i'll take a look later today thanks :)

If your at a school and you are positive people are hacking the network talk to the school. If you want to help the school fish around for traffic and save the ip/mac addresses for the computers that are sending out the unwanted data and turn that into the school. The school who administers the network could also configure their routers to not pass data off of certain ports. I'm not familiar with computer laws in Canada, but any sort of hacking in an education institution is a very serious offense in the US.

[yoda]

Thats one thing i want to do to, but i want to be able to make sure they can't hack me before i monitor the connections between my computer. The schools admins aren't really up to stuff if you ask me theres always away by getting around what they have set up. And as a matter of fact i'm not familiar with the laws either, but we have a school policy which states no hacking of any sort and so on and so forth, and hackings not really a big deal to our school because usually its for a good reason, like even i hack to make sure some students do there work and not play games.
