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.

Function

The remote login service rlogin uses the rlogin protocol to

establish a login session to the specified host. Generally, rlogin is

used on mixed UNIX networks where the PortMaster login

service is impractical to use.

Telnet is supported on most TCP/IP hosts. This login service

should be selected when the PortMaster and rlogin protocols are

not available.

The default port number is 23, but you can enter another

number.

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

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.
