use telnet or ssh in a web application

I am new to web application development and now want to implement an function. Let me describe it:
There is a remote machine or server, I can telnet or ssh to it and run some commands on the server using tools such as Putty or terminal. Now, I want to build a dialog box or input box in my web application, and users can use this box to ssh or telnet to the machine and run commands.
Any comments about this idea? Thanks so much.
