You might be able to do something with a 3270 console, but that's
probably unlikely to be useful in a VM environment (spare us VINPUT,
please!).
It would be a lot easier to configure (and probably more useful to have)
a root shell to always be running on the console without a Unix login
required. Since you already have a authorization method in place (the VM
userid login) that does password suppression correctly, that would be
the "right" thing to do -- after all, if you have the VM userid
password, you can already do all the harm that a root user can do, and
you have secure logging of the fact that the login occurred.
You know, linux can use serial ports as a console device... So why
hasn't IBM come up with a virtual serial port type of console system to
use instead? Something like having the console on /dev/ttyS0, and that
via some z/VM magic, is available on an IP as a port number. Telnet to
the port, and Linux's getty takes it from there. Or better yet, through
some z/VM magic, the serial ports could be mapped to another Linux
host's serial ports, say one set up as a console appliance... Then that
appliance could be configured to allow access to them in a variety of
ways, whether it be by port numbers, account names, ssh key, whatever.
I've been imagining this for a long time now, and just wondered why IBM
never did it.
A 2741 attached view a 270{1,2,3{ (I'd need to drag out tbe books to
rememebr which one) would probably do it.
