	# The /etc/motd file is displayed whenever someone connects. 
sudo nano /etc/motd
	- Remove contents (Erase the entire document)

	# This file erases any temporary motd messages upon reboot and sets it back to default. We want to disable this feature.
sudo nano /etc/init.d/motd
	- Comment out: uname -snrvm > /var/run/motd.dynamic (Meaning, place a # in front of uname -s....)

sudo nano /etc/ssh/sshd_config
	- Change from "PrintLastLog yes" to "PrintLastLog no" (toward the end of the file)

	# Next, we will create a new script that will display whenever someone logs in.
	# After typing the following command, the screen will be blank. Copy-and-paste all the content between the long lines of dashes.
	# The following example is for my EchoLink / VPN Multi-Server systems
sudo nano /etc/motd.tcl
