Hi chennaiite.
If you want answers here, perhaps it's an idea to show some effort on what you've tried so far.

Next try the Super Search to see if this question might be answered before.
Next read how (not) to ask a question, and give as much as possible information we can use to help
e.g. i'd like to know how you want to connect to the machine, is there a telnet server istalled, an ftp server, a self-written server listening on port xxx etc.etc.
