Configuring Dial-In Users 7-13
Configuring Login Users
To set the login service type for a login user, use the following command:
Command> set user Username service portmaster|rlogin|telnet|netdata [Tport]
Specifying a Callback Telephone Number
You can configure the login user for callback connections to enhance network security
or to simplify telephone charges. When a user logs in, the PortMaster disconnects the
user and then dials out to the telephone number specified for that user. The user is
reconnected to the host specified in the user table, via the same port on which the user
dialed in.
To enter the callback telephone number for a login user, use the following command:
Command> set user Username dialback String|none
To disable callback connections for the user, use the none keyword.
netdata The netdata login service creates a virtual connection
between the PortMaster port and another serial port on
another PortMaster, or between the PortMaster port and a
host. This login service creates a clear-channel TCP
connection. To connect to another PortMaster port using
netdata, you must configure that port as /dev/network
with the netdata device service and the same TCP port
number.
The default netdata port is 6000; however, you can specify
any TCP port number between 1 and 65535. This range
allows TCP/IP to be used with a hardwired connection using
an RS232 cable. However, some serial communications
protocols, such as FAX, might have potential latency
problems.
