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?

pwconv(1M) System Administration Commands pwconv(1M)
NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd
SYNOPSIS
pwconv
DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd.
pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is
already in /etc/shadow and should not be modified.
If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates
/etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in
/etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated.
If the /etc/shadow file does exist, the following tasks will be performed:
Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file.
Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow.
Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the corre-
sponding entry in /etc/shadow.
The pwconv command can only be used by the super-user.
FILES
/etc/opasswd
/etc/oshadow
/etc/passwd
