Rlogin — Although Rlogin was originally a UNIX protocol, it is now
supported by some non-UNIX machines as well. Unlike Telnet, Rlogin
allows a user logged into a host to access their accounts on other
(trusted) hosts without re-entering a password.
■
ClearTCP — Unlike Telnet and Rlogin, ClearTCP is not actually a login
service, it is a direct connection to a given TCP port number. Eight-bit
data is exchanged without interpretation.
The host type setting may override this setting. See step 2 for more
information.
Type
The following are valid types for a login user:
■
login
■
login, callback
If you include callback in the user type, you need to specify a phone
number at which the user is called back using the following command:
set user <name> phone_number <number>
At this point, it may be helpful to use the show user command to display
the user's default values. This lets you decide which parameters you need
to set and which parameters you can leave as defaults.
2 Configure login user parameters with the following command:
set login user <name>
host_type [prompt | select | specified]
login_host_ip_address <ip_address>
login_service [rlogin | telnet | cleartcp | ping]
tcp_port <port_number>
terminal_type <string>
Host Type
Determines how the user is connected to a login host. The default is
select
.
■
prompt — If the user is prompted, this setting overrides login service
setting. At the prompt, the user can enter the login service (for
example,
Telnet
) and the host name or address, or type
connect
and enter host name or address to use the default login service.
