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 SDT tunneling topics:
Using SDT Connector for out of band access (Section 6.5)
Automatic importing and exporting of 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)
Using SDT to IP connect to hosts that are serially attached to the Console Server (Section 6.10)
6.1 Configuring for SDT Tunneling to Hosts
To set up the Console Server to SDT access a network attached host, the host and the permitted services
that are to be used in accessing that host need to be configured on the gateway, and User access
privileges need to be specified:
Add the new host and the permitted services using the Serial & Network: Network Hosts menu
as detailed in Network Hosts (Chapter 4.4). Only these permitted services will be forwarded by
SDT to the host. All other services (TCP/UDP ports) will be blocked.
Note Following are some of the TCP Ports used by SDT in the Console Server:
22 SSH (All SDT Tunneled connections)
23 Telnet on local LAN (forwarded inside tunnel)
80 HTTP on local LAN (forwarded inside tunnel)
3389 RDP on local LAN (forwarded inside tunnel)
5900 VNC on local LAN (forwarded inside tunnel)
73XX RDP over serial from local LAN – where XX is the serial port number (i.e. 7301to 7348)
79XX VNC over serial from local LAN – where XX is the serial port number
Add the new Users using Serial & Network: Users & Groups menu as detailed in
Network Hosts (Chapter 4.4). Users can be authorized to access the Console Server ports
and specified network-attached hosts. To simplify configuration, the Administrator can
first set up Groups with group access permissions, then Users can be classified as
members of particular Groups.
6.2 SDT Connector Configuration
The SDT Connector client works with all Console Servers. Each of these remote Console Servers has an
embedded OpenSSH based server. This server can be configured to port forward connections from the
SDT Connector client to hosts on their local network, as detailed in the previous chapter. The SDT
Connector can also be pre-configured with the access tools and applications that will be available when
access to a particular host has been established.
