Telnet & SSH Functions
10.3. The Direct Connect Feature
The Direct Connect feature allows you to initiate a Telnet, SSH or Raw Socket session
with the TSM/RSM and make an immediate connection to a specific serial port of your
choice, without first being presented with the command interface. This allows you to
connect to a TCP port that is mapped directly to one of the TSM/RSM's serial ports.
Direct Connect employs unique, pre-assigned TCP port numbers for each serial port.
The user connects to the port of choice by including the associated TCP port number
in the Telnet or SSH connect command line. The Direct Connect feature can be
individually configured at each serial port and can be used to connect to Any-to-Any,
Passive, Buffer, or Modem Mode ports.
10.3.1. Standard Telnet Protocol, SSH and Raw Socket
The Direct Connect feature allows you to establish port connections using either
Standard Telnet Protocol, SSH encryption or Raw Socket. When Standard Telnet
Protocol is used, the TSM/RSM will respond to all IACs.
When configuring a serial port to allow Direct Connections using SSH protocol, note
that the Direct Connect option (Port Configuration Menu, Item 31), must be set to
"On - Password" as described in Section 10.3.2.
When configuring a serial port to allow Direct Connections using either Standard Telnet
or Raw Socket Mode, note that the Direct Connect option (Port Configuration Menu,
Item 31) may be set to either "On - Password" or "On - No Password".
10.3.2. Configuration
The Direct Connect Function is configured on a per port basis using the Port
Configuration Menus (/P nn), item 31, "Direct Connect". The following options are
available:
1. OFF: Direct Connect disabled at this port. (Default)
2. ON-NOPASSWORD: The Direct Connect feature is enabled at this port, but no
password is required in order to connect to the port.
a) When the Telnet connection is established, the user is immediately connected
directly to the specified port, and the client is notified at the TCP level.
b) This option is intended for situations where security is provided by the attached
device.

3. ON-PASSWORD: The Direct Connect feature is enabled at this port, but a
password must be entered before a Direct Connection is established.
a) Upon login, the TSM/RSM will prompt for a username and password. If a valid
username/password is entered, the TSM/RSM will return a message which
confirms the connection and lists the name and number of the port (providing
the user account allows access to the target port.)
b) If a valid username / password is not entered in 30 seconds or three attempts,
the port will timeout and disconnect.
