I'm trying to enter someone's pc and use his PC for educational purposes. I really hope that i get help as soon as possible. Thanks for your support.

For the good helpers to help you first give them a good background what you have done and what is the status of the two pc's. How are they connected? USB or ethernet? What OS are they running?

A good answer always comes from a good question.

Describe your situation fully and clearly. That's the first thing to do in order to obtain effective help.

I'm using latest version of ubuntu on one of them and windows 7 on the other. They are not connected to eachother at all, i was thinking more like to connect them using IP address or by an email sent to my ubuntu pc from my windows 7 pc.

Okay first you will need to connect them to a switch as neighborhood clients. Fix the IP addresses with a common netmask --they must see each other in a single network.

Which machine are you trying to connect from and to?

Are you looking for a command line login or a graphical login?

I'm sorry, not to be rude but non of this was helpful.
This was just a waste of time.

Wow, you give little or no info and expect a perfect answer? A good answer requires a good question.

A good answer requires an expert

Now matter how good the expert, they cannot answer a non-question. You were politely asked for more info. If you took time to provide it we could help

How can anybody possibly answer your question when you've provided us with no information on which system is which, no information on how the systems are connected, and no information on what you even want to DO beyond "connecting" or "entering the pc". This can mean a LOT of different things, and yet you haven't even bothered to answer our questions when asked.

It would be like going to a car forum and saying, "My car is making a noise, what's wrong and how do I fix it?", providing no additional information when asked, and then getting mad when your problem isn't correctly identified and solved in less than half a day.

I believe one must know a terminal from a console.
I believe "enter" is "login to", so one must ask

Do you have permission to do so?

lowriderzxxx, don't worry if you don't fully understand yet what is to be done: sometimes a problem comes by its face alone without us perceiving fully what its nature is. Yet at least, what our helpers wanted to know is just "a clear description of what you have, what you have done so far, and what you wanted to attain, in simple and clear english." The cooperating attitude that LQ shows to a newbie is overwhelming indeed, for this value LQ has gained a place in this world.

Don't give up. Speak to them whatever it is you are facing.

Be honest. Be clear.

Be confident. For like everyone here, you too are "no less than the trees and the stars..."

Welcome again, and enjoy your privilege to speak out and obtain help.
