From: newt@eng.umd.edu (Daniel S. Ridge) Subject: ANS: ser. hang under X and QUES: login over serial Date: 17 Apr 1993 07:01:12 GMT
I posted yesterday asking for help on my linux communications
problems, and I had not realized that X didn't support IRQ sharing,
and the mouse on com1 conflicted with the 2400 baud modem on com3
I have neither the time nor the patience to hack IRQ sharing,
so I moved the mouse and lost half my modem functionality. Ah well,
it is well worth it to run xdaliclock remotely(If slowly! Hint: dont ever do
this) Thank you to all who helped me on this, especially Gebran Krikor.
I have one more question for the gurus, or even enlightened neophytes.
I try to spawn a getty to a serial line to support a terminal, and
I encounter difficulties. the getty accepts the login properly, and the
login process is spawned on the linux box(as revealed by ps), and
the password checking is not handled. Either the password
echos on the terminal and does not process, or it never prompts for
a password in the first place.
This is what I have done so far. I set it(BTW *never* *ever* do this)
so that root can login from the serial port, and then root
or any other id without passwd authentication works properly.
It logs in fine if I dont need to use a password.
I have redirected the input , output, and error for a shell over the serial
line and that works okay,
I have tried the same thing with login, and it exhibits the characteristics
of the spawned getty detailed above. This leads me to believe
that the problem is in login.
Sound good?
Have a fix?
Thanks in advance for all your help.
