Do you need a real Telnet client? The Telent protocol is kind of ...
wacky ... to work with.

You are only needed to open a server socket and read command (through characters
is inputed to InputStream).

It is very simple. You dont need source  code, you need to think & explore!
We r doing a project  on network  monitoring using java.
i request  all java  programmer to help  out from the
problem we r facing.

we r trying to deveelop a java telnet  application.

pls help us to either
1)find how to proceed to do this application
or
2)give us the java source code...

What school / course are you doing this for, curious.

Open socket, get input and output stream.
wrap streams into reader and writer.

write command to writer. read response from reader.

That's essentially it.

They hairy wacky mess comes into play when you want to interpret
screen controls. vt100 vt202 xterm, whatever, etc.

There are a few libraries ported from available C code.

MindTerm a bunch of VT terminal interpreters built in, but you can
find many other ones through freshmeat.net
