Telnet Server - User Authentication

[tejeshwer]

Hi,

We are implementing a telnet server , using the example provided , we did
not develop anything specific around telnet , we are just using the standard
text protocol provided in the examples, 

We are not stuck with one problem , when ever the user - tries to login into
the system the password should be masked or discarded either way - but
unfortunately - I'm unable to implement that . 

I have tried following ways :

1 : Implement a AuthenticationHandler (FrameDecoder,Sting
Encoder,SimpleUpStreamHandler) - which would accept the username and remove
these decoders and add a passwordHandler - which would just discard the
message ( replica of discard handler) - ( but this did not work) . 

2 : Tried to mask the string with \010* character - but i'm unable to
control the user input.

Require assistance - can any one please help or redirect me to post if this
has already been answered ?

Thanks
