Telneting from the Router
The router provides three modes of access to host services:
■
Using the CONNECT command on page 11-13 of Chapter 11, Terminal
Server to access asynchronous services. These are typically hosts connected
directly to asynchronous ports on the router and defined as services using
the SET SERVICE command on page 11-17 of Chapter 11, Terminal Server.
■
Using the CONNECT command on page 11-13 of Chapter 11, Terminal
Server to access Telnet services. These are typically Telnet hosts defined as
services using the SET SERVICE command on page 11-17 of Chapter 11,
Terminal Server.
■
Using the TELNET command on page 11-24 of Chapter 11, Terminal Server to
access Telnet hosts.
Each entry in the database has a TELNET attribute, which determines which
modes of access the user is permitted to use.
All users can use the CONNECT command on page 11-13 of Chapter 11,
Terminal Server to access asynchronous services, although users accessing the
router via Telnet or a terminal attached to an asynchronous port in SECURE
mode must login first to gain access to the command prompt.
Users logged into the router via a terminal attached to an asynchronous port
can also use the CONNECT command on page 11-13 of Chapter 11, Terminal
Server to access Telnet services. In addition, if the user is logged in to an
account with the TELNET attribute set to “ON” the user can use the TELNET
command on page 11-24 of Chapter 11, Terminal Server to Telnet to remote hosts.
Users logged into the router via Telnet can, by default, only use the CONNECT
command on page 11-13 of Chapter 11, Terminal Server to access asynchronous
services. If the user is logged in to an account with the TELNET attribute set to
“ON” the user can also use the CONNECT command on page 11-13 of Chapter
11, Terminal Server to access Telnet services and the TELNET command on
page 11-24 of Chapter 11, Terminal Server to Telnet to remote hosts.
A manager can use the TELNET attribute to allow users connected to the
router via a terminal to access a restricted set of Telnet hosts, by defining those
hosts as Telnet services (see the description of the SET SERVICE command on
page 11-17 of Chapter 11, Terminal Server and setting the TELNET attribute to
“OFF” for selected accounts. Users logged in to one of these accounts can use
the CONNECT command on page 11-13 of Chapter 11, Terminal Server to access
the Telnet services but can not use the TELNET command on page 11-24 of
Chapter 11, Terminal Server to access any other Telnet hosts.
Counters
A number of counters record activity associated with the User Authentication
Database. Counters relating to specific users in the database can be displayed

Global counters and configuration parameters can be displayed with the
