Setting Up a Modem Service

Security Server Configuration 4.6.5 Setting Up a Modem Service The example displayed in Figure 4-18 is rather detailed, but once you have created a service or two, the process should become largely intuitive. Remember that the Show/Monitor/List Services commands are available to show you exactly what has been set up so far. If you are unsure or think you may have made a mistake, delete the service (using Clear/Purge Service) and start from scratch. Refer to the upcoming section for modem-specific configuration issues.

XON/XOFF flow control has been enabled for the modem. Access to the port is now dynamic so that both remote and local users can access the modem to dial in or out. Modem control and password protection are both enabled. Users who dial into the modem and connect to the Server's serial port will have to enter the login password due to the Define Port Password Enabled entry. This option can be omitted if not desired. The service is set up as with the previous example, but a password has been enabled for both the service and the port. Users who connect to the service locally or from another host on the network will have to enter the service password (loco) to use the service to connect to the modem and dial out. This option can be omitted if not desired. Note: For more information on port settings, see Chapter 5. Since modems do not log the user out when a connection is finished, you will probably want to have the Break or Local key available so you can return to the ETS command line; see Set/Define Port Local for more information. If you wish to disconnect from the modem session, use the Disconnect or Logout command. If a port and modem are to be used to allow dial in connections, you may wish to make the port Secure. Secure status prevents dial-in users from changing the port characteristics and preventing other users from being able to dial in properly. 4.7 Security Security measures are available to monitor users and to restrict users from unwanted activity. Security can be implemented server-wide, or it can be configured for individual ports as desired. The following section discusses server-wide security measures; for port security measures, see Chapter 5, Ports. 4-10

Setting Up a Modem Service
The example displayed in Figure 4-18 is rather detailed, but once you have created a service or two, the
process should become largely intuitive. Remember that the
Show/Monitor/List Services
commands are
available to show you exactly what has been set up so far. If you are unsure or think you may have made a
mistake, delete the service (using
Clear/Purge Service
) and start from scratch. Refer to the upcoming
section for modem-specific configuration issues.
Figure 4-18:
Modem Service Setup
Because many of the commands shown are similar to the ones in the previous example, only those that differ
will be explained:
The port is configured in much the same way as in the simple service example. XON/XOFF flow control
has been enabled for the modem. Access to the port is now dynamic so that both remote and local users can
access the modem to dial in or out. Modem control and password protection are both enabled.
Users who dial into the modem and connect to the Server’s serial port will have to enter the login password
due to the Define Port Password Enabled entry. This option can be omitted if not desired.
The service is set up as with the previous example, but a password has been enabled for both the service and
the port. Users who connect to the service locally or from another host on the network will have to enter the
service password (loco) to use the service to connect to the modem and dial out. This option can be omitted
if not desired.
Note:
For more information on port settings, see Chapter 5.
Since modems do not log the user out when a connection is finished, you will probably want to have the
Break or Local key available so you can return to the ETS command line; see
Set/Define Port Local
for
more information. If you wish to disconnect from the modem session, use the
Disconnect
or
Logout
command.
If a port and modem are to be used to allow dial in connections, you may wish to make the port Secure.
Secure status prevents dial-in users from changing the port characteristics and preventing other users from
being able to dial in properly.

Security
Security measures are available to monitor users and to restrict users from unwanted activity. Security can
be implemented server-wide, or it can be configured for individual ports as desired. The following section
discusses server-wide security measures; for port security measures, see Chapter 5,
