Users Connecting to the LAN
For a user to connect to the LAN through the Terminal Server from a serial device, the Line
Service
can be set to any
Direct
or
Silent
setting, plus
Bidir
or
DSLogin
.
User accounts should be created when:
z
authentication is being done locally by the Terminal Server.
z you want to create predefined sessions for a user to limit that user’s access to the network.
Connecting To the Terminal Server
When a user connects to the Terminal Server, that user is authenticated and is usually set up
with predefined sessions or given the opportunity to configure a
Free Session to access any host
using any protocol (must have a
Level
of at least
Normal
to configure a
Free Session
). In this
example, the user must have a
Line
and
User Service
of
DSLogin
and
DSPrompt
, respectively.
So, user Dennis is authenticated by the Terminal Server and then chooses to configure a
Free
Session to the HR_Server using the Telnet protocol (Dennis could have attempted to access any
host on the network).
Connecting Through the Terminal Server
When a user connects through the Terminal Server, that user is authenticated and is usually set
up with a
User Service
that, once authentication is completed successfully, passes the user onto
the specified host. Therefore, the
Line Service
is set to
DSLogin
and the
User Service
is set to
whatever protocol the user will use to access the host; in this example, the User Service is set to
Dir Telnet . When User Service Dir Telnet is selected, the IP address of the HR_Server is
specified as the target Host IP. User Dennis will always have to log into the same server with this
configuration.
