# cd /etc/init
# vi control-alt-delete.conf
# control-alt-delete - emergency keypress handling
#
# This task is run whenever the Control-Alt-Delete key combination is
# pressed. Usually used to shut down the machine.
start on control-alt-delete
exec /sbin/shutdown -h now "Control-Alt-Delete pressed"
This change will be picked up when the system is rebooted.
8.2.6 Setting the system to logoff when Linux is shut down
When Linux is shut down, the default is for the virtual machine to remain logged on even
though it is not running an operating system. It is more convenient for the user ID to be
logged off, both at z/VM SHUTDOWN time and for getting a refreshed 3270 emulator session. To
do this, perform the following steps:
► Edit the file /etc/rc.d/rc.local and add two lines at the end as follows:
# cd /etc/rc.d
# vi rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
chshut halt vmcmd logoff
chshut poff vmcmd logoff
The z/VM user ID should now be logged off when you halt or power off Linux.
8.2.7 Configuring SSH keys
Recall that you generated SSH keys on the cloner in 7.2.8, “Configuring SSH keys” on
page 125. Now it is time to copy these keys from the cloner to the golden image.
► Create a new directory (if one doesn’t already exist) on the golden image where the public
key will be copied:
# cd /root
# mkdir .ssh
► Set the permissions to 700 so that it can only be accessed by root:
# chmod 700 .ssh
► Copy the public key to the name authorized_keys using the secure copy command scp:
# scp 9.60.18.223:/etc/ssh/ssh_host_dsa_key.pub /root/.ssh/authorized_keys
The authenticity of host '9.60.18.223 (9.60.18.223)' can't be established.
RSA key fingerprint is c7:d6:3b:8c:20:57:06:fc:8c:71:80:a5:4f:72:47:38.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '9.60.18.223' (RSA) to the list of known hosts.
