[This is the first of several messages that have been in my backlog.
With changing jobs and trying to get net feeds established, I haven't
had time to do mod.os.unix (soon to be renamed something like comp.unix).
My apologies for the long delay. I will include a "Posted:" header line
to indicate the date the posting originated for the backlog messages.

I am attempting to write a new getty to run on an IBM RT running
AIX ( SYSV ). The client for our package wants a friendlier logon
screen based upon curses. They want two methods of logging on.
If they give a userid/passwd combo then they will enter into our
package. If they enter UNIX for the userid they want to get a
regular unix login.
My problem is that when I exec '/bin/login', login only prompts
for the userid, and always lets the user in without asking for
a passwd. The best I can tell is that '/dev/tty' is not being
associated with the control group. The reason that the user is
not prompted for a passwd is that 'getpass' tries to open '/dev/tty'
and when it can't it return's NULL which login is not expecting.
Can any body validate my observations, and hopely tell me how
to attach '/dev/tty' to the control group.

If so, I'm surprised that something like this snuck through or is considered acceptable. If this behavior is allowed in P1003, might I request that it be entered in the "Weirdnix" contest, or is it too late? -- ...!decvax!decuac - Phil Kos \ The Johns Hopkins Hospital ...!seismo!mimsy - -> !aplcen!osiris!phil Baltimore, MD / ...!allegra!mimsy -
