getty without Login

[Luis Lino_1]

Dear friends,
Can I disabled login and password when I try to connect by tty2aX?.

Could you help me, please?

Thanks

Shalom,

I'm sure you can by blanking out the password in /etc/passwd

This would have a few effects:
1) It would enable the user without a password from any type of login.
2) It would cause you to FAIL you rnext security audit.

There are means of getting access to a system that won't cause the above effects.

What is it your trying to do on that tty?

Perhaps there is another command that you can use to do what you would like to do.

It's not clear what you want to accomplish. If you do not want any logins from tty2aX then remove the getty line in inittab or change :respawn: to :off: and then kill that specific getty. On the other hand, if you want getty to set a permanent baud rate, parity and other settings, then you can add an entry similar to the systty entry in inittab:

tt2x::sysinit:/sbin/stty 9600 clocal icanon echo opost onlcr ixon ixoff icrnl ignpar
Now at the startup of the system, the port will be set to those stty settings. The default for an unset port is 300 baud.

Are you looking for a way to have someone connect via a particular tty and get logged in without being asked for a login name or password? If so you should seriously consider the security implications. You could have a user without a password, but they would then be able to login from anywhere without a password.

What is your specific need for this functionality?

regards,

Darren.

Yes, this would be the case if your inittab file has getty's posted for each port. Edit the /etc/inittab file, then for each of the tty ports, replace the word respawn with the word off, or simply remove the tty entries 1 through 8 then save the file and update the init program with:

init q
