Hi,

As far as I know, you can't. You can however add a 'magic' to your login.defs file. In this way, you can start your own script after mgetty detects this 'special' loginname. It won't ask for a password, mgetty never does. It usually starts 'login' to get the password.

I dont think this will be the solution for you, because it's more or less the same as adding a user without a password and giving this user your script as shell..

alexbik is right. I don't know your needs, but I can imagine you will ask the user some kind of authentication. Change your script to receive the first token of the chat as the first parameter. Then change /bin/login for your script in the /etc/mgetty+sendfax/login.config:
* - - /bin/login @
(the @ means whatever parameter your login: prompt reveives...) Then invoque mgetty in your /etc/inittab as:
/sbin/mgetty -i /dev/null ttySx
adding -p "some_prompt_opcionally".
Of course there's allways the hackers way (if you can read C code, you can get whatever you want: mgetty sources are very clear.)

Good luck
