Using the MSS Interactive Connections
5 - 5
5.2.2 Outgoing Connections
The MSS can make outgoing connections to hosts on TCP/IP, IPX/SPX, and LAT networks.
NOTE: Outgoing connections can only be made from the serial port.
5.2.2.1 Telnet
To start an outgoing Telnet session to a remote host on a TCP/IP network, type Telnet at the Local
prompt, followed by either the host’s name or its numeric IP address.
Figure 5-9: Opening a Telnet Connection
NOTE: If a preferred or dedicated service has been configured, a host name is not required.
You can also make a Telnet connection to a specific port number, as described in Status Displays on
page 5-1.
Sometimes the presence of Newline characters creates a problem during a Telnet session. When
the MSS Telnet padding feature is enabled with the Change Telnetpad command (the default), the
server will automatically pad carriage returns with null characters. This behavior works for most
applications and is recommended in the Telnet RFC.
5.2.2.2 Rlogin
Rlogin allows a user to log into a remote host as if he or she were a local user. For example:
Figure 5-10: Connecting with Rlogin
A user’s MSS username (the name used for login to the MSS) becomes the login name for the
remote host. Unless the username is password protected or Rlogin is disabled on the remote host,
the user will be logged in normally. A different username can be specified for the remote login
after the MSS username.
NOTE: Because Rlogin can bypass the normal password/login sequence and is therefore a
potential security problem, it may be disabled on some hosts.
5.2.2.3 SPX
For SPX connections on IPX networks, the connecting device and the target device must advertise
themselves via SAP announcements. The MSS advertises itself at boot time as MSS_xxxxxx_S1
where xxxxxx represents the last six digits of its hardware name.
As long as the target device is advertising itself via SAP announcements, the MSS should be able
to make an SPX connection. Enter the following command including the target device’s SAP
name.
Figure 5-11: Making an SPX Connection
To view all available SPX devices (those advertising themselves via SAP announcements) enter the
Show Node LAT/SPX
command.
