6. Secure SSH Tunneling and SDT Connector
Each Black Box console server has an embedded SSH server and uses SSH tunneling so remote users can securely connect through the console
server to Managed Devices—using text-based console tools (such as SSH, telnet, SoL) or graphical tools (such VNC, RDP, HTTPS, HTTP, X11,
VMware, DRAC, iLO).
The Managed Devices you access can be located on the same local network as the console server or they can be attached to the console server via a
serial port. The remote User/Administrator connects to the console server thru an SSH tunnel via dial-up, wireless or ISDN modem; a broadband
Internet connection; the enterprise VPN network; or the local network.

To set up the secure SSH tunnel from the client PC to the console server, install and launch SSH client software on the User/Administrator’s PC,
Black Box recommends that you use the SDT Connector client software supplied with the console server. SDT Connector is simple to install and
auto-configure and it provides all your users with point-and-click access to all the systems and devices in the secure network. With one click, SDT
Connector sets up a secure SSH tunnel from the client to the selected console server, then establishes a port forward connection to the target
network connected host or serial connected device. Next, it executes the client application that it uses in communicating with the host.
This chapter details the basic SDT Connector operations:
• Configuring the console server for SSH tunneled access to network attached hosts and setting up permitted Services and user access
(Section 6.1).
• Setting up the SDT Connector client with gateway, host, service, and client application details, and making connections between the
Client PC and hosts connected to the console server (Section 6.2).
• Using SDT Connector to access the Management Console via a browser (Section 6.3).
• Using SDT Connector to Telnet or SSH connect to devices that are serially attached to the console server (Section 6.4).
The chapter then covers more advanced SDT Connector and SSH tunneling topics:
• Using SDT Connector for out-of-band access (Section 6.5).
• Automatic importing and exporting configurations (Section 6.6).
• Configuring Public Key Authentication (Section 6.7).
• Setting up a SDT Secure Tunnel for Remote Desktop (Section 6.8).
• Setting up a SDT Secure Tunnel for VNC (Section 6.9).
