ASCII character to accept logon password

Hey all,

Just found your forum...Looks super rich with info! Can't wait to get through it all.

I am currently writing a web app in .net that telnets into a unix server (require uid + passwd), runs a command, and returns that output to be displayed on the web page.

I have gotten through the initial TelNet option negotiation and have hit the log on screen. Of course, I'm transferring bytes in my network stream so all my i/o is ascii.

I've been able to enter my username and am prompted for a password. I send an array of bytes, which is my passwd, but the unix box sits there. Finally, half a minute later, I receive the text:

/dev/pts/96: 3004-031 Password read timed out -- possible noise on port

I've tried using ascii 13, and 10 to attempt a carriage return, and I've even sent negotiation 'Go Ahead' command even though they're suppressed.

Does anyone know what my UNIX box is waiting for?

Name
       yppasswd - change password in yellow pages (YP) service.

Syntax
       yppasswd [ name ]

Description
       The  command lets you change your password in the yellow pages (YP) map, a network data base service.  Only you or the superuser can change
       your YP password.

       When you enter the command, the program prompts you for the old password and then for the new password. Note that  the  passwords  are  not
       displayed on the screen.

       Next,  the  program asks you for the new password again, to verify that you have typed it correctly.  If you do not type the passwords cor-
       rectly, you will receive an error message after you enter the new password.

       Your new YP password must meet one of the following requirements:

	  o It must be a combination of at least six alphanumeric characters, or

	  o It must be a minimum of four characters, with at least one being non-alphanumeric, such as a control sequence.
       The command does not change the YP password.  This command only changes the local password file and not the YP master password  file.   See
       Chapter 3 of the Guide to the Yellow Pages Service for further information.

Diagnostics
       Please use a longer password
       Your new password does not meet the minimum length requirement.

       Mismatch- password unchanged
       You misspelled your new password or its verification.

       couldn't change passwd
       Your new password can not be activated. It must be different from your old password and your login name.

Files
       Password file

       Yellow Pages directory
