hey Paul i need to install ne thing in ubuntu machine? like telnet or ne thing else if i need to install then please tell me how would i go for this?
For using Putty you mean? Maybe, you'll need an ssh-server (as Putty uses SSH). So, in Ubuntu start your favorite Package Manager and search for openssh-server (or of course use apt-get or aptitude to install it).
If you want to use Linux and
can't connect to that Ubuntu for some reason (e.g. the SSH Port is being blocked - rare but it happens), you could try using a Live Distribution, e.g. "Damn Small Linux", which you can even run from within Windows! If you want more functionallity and can boot the PC from CD, try Knoppix!
Then there's the possibility of using Cygwin, which offeres a Unix like console under Windows... there are thousands of possibilities.
Of course, more information on any of these solutions can be found either with Google (or your favorite search engine) or, if more complex, in this Forum.
