Adding a Remote User to the User Table

Users for terminal server applications are configured as login users.

Step 1 - Add the user to the User Table

Type the following command:

add user <name> password <password>

Step 2 - Configure the user

You must specify a login service for each user. Specifying a host for each user is optional if you have either a port default or a global default host defined.

Host

This tells the NETServer which host the user will be logging in to. Use the following command:

set user <name> host <host type>

<host type> is default, prompt or a specific IP address

Default	(Default) The user is passed on to the default host
	for the port he or she is connected to.
	set user <name> host default
Prompt	The user is given a Host: prompt. Users type the
	name or IP address of the host they want.
	Note that if the port default host type is also
	prompt, the host prompt appears before login.
	Otherwise, the host prompt appears after login.
	set user <name> host prompt
IP Address	The user is connected to a specific host other than
	the default host. Type in the IP address of the
	specific host.
	set user <name> host <IP address>
