I am setting up a long-range wireless serial terminal (with a pair of XBees, if anyone is wondering) connected to my Linux box. It's going great, but sometimes a keystroke doesn't go through. This is usually manageable, I'll see the lack of it and hit it again. However, it's bad when I have to try a few times to type my password because Linux doesn't show anything. I've already added the
pwfeedback line to my sudoers file, but I'd like the login prompt to show some feedback as well. The Linux machine is running Debian (it's actually a raspberry pi that manages most of my home network).
Is it possible to change the tty login prompt to give feedback as I type my password?
Instead of this:
Raspbian GNU/Linux 7 linuxbox ttyAMA0 linuxbox login: skylarmt Password:
I would like this:
Raspbian GNU/Linux 7 linuxbox ttyAMA0 linuxbox login: skylarmt Password: **********
