how to you access a computer remotely using its IP adress over the internet? how about the security issues?

Question

inquiry to facilitate file sharing with a friend, so not a hacking apprentice.

Answer 1

You need to run a Remote Administration Server or Remote Desktop on the computer, and then connect to it with a client application. The point of firewalls is it prevent this type of unwanted network communication, but ofcourse there are legitimate situations when somebody would want another person to remotely do something on their computer. Now, to get by firewalls and routers, Remate Admin Trojans act as the client themselves a connect back to the controlling computer in various tricky ways.

I'll refer you to a popular R.A.T. from back in the day. It is nolonger maintained, and it's startup methods are well known by all antivirus and antispyware programs, so it is really nolonger a threat. It's a useful education tool though, as it allows you to run a safe local server.

Edit - For simple file sharing, one of you can run a FTP Server. Or simply use IRC, if you don't want to setup a server.

Answer 2

Wow, the answer to that one is complex. I'm guessing your the "average" computer user, so setting up a VPN (virtual private network) would be a little daunting. Without some type of communication software, i.e. PcAnywhere (firewalls and routers kill you) on the computers on both ends it's tough. If your running Windows XP you could use Windows "Remote Desktop Connection" It's easy to establish a connection with. The easiest way is web based software like LogMein or GoToMyPc.

Answer 3

Telnet was the original way to access other pc's. In a terminal/command prompt type

[code]
telnet
[/code]

You'll then need an account on that pc that you can use to login with. Additionally, the firewall on the remote pc must allow the type of connection you are using through it. If you have administrator privileges on it, no problem. If you don't, you will have to bypass any security, e.g. crack/hack.

Modern secure systems might use SSH to access remote pc's, but the same rules apply as above.

Answer 4

Absolutely. I have a LAN in my home, 2 pc's and and X box 360 sharing a 3 MBPS connection via wireless/wired router. Sometimes if someone is downloading something, everyone else's connection speeds lag really bad though, so I'm considering a dedicated connection for my p.c.

Answer 5

If you are trying for malicious purpose, it si illegal. For your academic interest, you can use Remote Desktop to access a remote PC or server. But the corresponding party has to allow you by installing and you need to know the username and password for the same. Beware of consequences, if you are doing it illegaly.

Answer 6

What you are asking about is called hacking, and I will not help you or anyone else learn to be evil!

Answer 7

there is an option called remote login or remote desktop you can use them for remote login.
