Example: Enabling a Preferred LAT Service on a Specific Node and Port
The following example shows how to specify that port 5 connects to port JAMES on
node MARKETING for service FILES:
Local> CHANGE PORT 5 PREFERRED FILES NODE MARKETING DESTINATION
JAMES
For the Telnet Protocol
To set an Internet host as a preferred service, the port’s default protocol must be set to
TELNET. You can use the host’s Internet address, domain name, or relative domain
name if the host is defined in a name server; however, you cannot use the entire domain
name if the name is more than 16 characters, including the dots.
Example: Enabling a Preferred Telnet Service
The following example shows how to enable a resource on the TCP/IP network,
SALE.MKT.DEC.COM, as a preferred service on port 5:
Local> CHANGE PORT 5 PREFERRED SALE.MKT.DEC.COM
Specifying the Port USERNAME
By factory-set default, the Enter username> prompt appears when a user logs in to the
access server port. The access server uses the user name as the string the user enters in
response to the Enter username> prompt. However, the access server uses the port’s
name as the user name when the user enters Ctrl/Z instead of a user name.
You can use the USERNAME characteristic to establish a permanent user name (1 to
16 ASCII characters) for a port. In this case, the Enter username> prompt is not
displayed when a user logs in to the access server. Always make an effort to specify a
unique user name, since the access server does not prevent duplicate user names.
Examples: Configuring Port USERNAME
The following example sets the port 5 user name to “Barney”:
Local> CHANGE PORT 5 USERNAME "Barney"
If you do not use the quotation marks in the command, the user name will appear in
uppercase (for example, BARNEY instead of Barney).
To clear USERNAME, enter empty quotation marks as follows:
Local> CHANGE PORT 5 USERNAME ""
USERNAME is designed to accommodate interactive terminals that have one
permanent user. Terminals that are usually shared should not have a permanent user
name assigned, and the Enter Username> prompt should be entered upon login.
If AUTHENTICATION is enabled on the port, the port user name may be set to the
Kerberos principal name of the port’s permanent user.
