How to use gnome-terminal -e login

[tpang]

I am pretty new to linux (RedHat 8.0), really need some help here.

We are porting a HP-UX system on to RedHat.

The system is an automated system.
When PC boot,
we use the autologin feature, login as USERA,
the system will starts automatically,
user interact with the system through menu and buttons.

In the old system, the operator can start a terminal sessin
by clicking on a menu item.
We used to run 'hpterm -e login&'

The RedHat system, i thought i use 'gnome-terminal -e login'

i notice the 3 different login behavior,
notice we already autologin as USERA

1. gnome-terminal -e login
login: USERB
Password: XXXXX

Login Incorrect

2. gnome-terminal -e login
login: USERA (login as myself)
Password: XXXXX

Login CRASH

3. gnome-terminal -e login
login: root
Password: XXXXX

Login CRASH

Please Help,

I'm guessing that HP-UX /bin/login is SUID root, right? On Linux systems it normally isn't, and thus you can't make a program that USERA starts to either call setuid() or read the shadow file.

Instead, try using su instead. Try making the terminal call a shell script that looks something like this:

#!/bin/sh

echo -n 'User name: '
read username
exec su - "$username"
