Connect To Another Computer

Use SSH. To do so, install openssh-server on your friends machine and connect to the machine like:

ssh user@host

Where user is your username on that machine and host is the hostname or the IP of the remote machine.

In my system i already installed openssh-client,openssh-server.In my
friend system he installs openssh-clinet
and i also tried which you said as above.
but it says like connection timed out.

To make that more clear: The server has to be installed on the system you are connecting to (aka. your friends system). Also the server has to be accessible to you, no firewall etc.

He is using Ubuntu 10.04 in that when he is try to install openssh-server
it gives error .so i installed openssh-server on my system.So according to
now he can access my system.And please tell me what you mean be "no
firewall". Because in windows there are some settings related to
firewall.But in ubuntu i don't know so please tell me what are those
settings.

Well, if he has not configured anything special that thing with the firewall is not a problem.
It would also be very helpful if you post the exact error from the installation here, so we can assist to resolve it.

successfully installed i don't how?.

ssh: connect to host 10.128.93.226 port 22: Connection timed out

The IP adress 10.128.93.226 is within the IANA-defined private address range that cannot be reached from other parts of the internet http://en.wikipedia.org/wiki/Private_network That means that there is no way to reach your friend's computer with that address from somewhere else in the internet, just from other computers inside the local area network of his computer.

Are you in the same LAN as he is, or not?

No we are not in the same LAN.He is using USB Modem so he got the ip
address from mobile operator and i got the ip from my ISP.So at last if we
can't connect using private address can you know how can we get public
address.
