Chapter 6: Secure SSH Tunneling & SDT Connector
6.10 SDT IP Connection to Hosts
Network (IP) protocols like RDP, VNC and HTTP can also be used to connect to host devices that are serially connected through
their COM port to the Console Server. To do this you must:
• establish a PPP connection (Section 6.7.1) between the host and the gateway, then
• set up Secure Tunneling - Ports on the Console Server (Section 6.7.2), then
• configure
SDT Connector
to use the appropriate network protocol to access IP consoles on the host devices that are
attached to the Console Server serial ports (Section 6.7.3)
6.10.1 Establish a PPP connection between the host COM port and Console Server
(This step is only necessary for serially connected computers)
Firstly, physically connect the COM port on the host computer that is to be accessed to the serial port on the Console Server.
Then:
A. For non-Windows computers (Linux, UNIX, Solaris etc), establish a PPP connection over the serial port. The online
tutorial http://www.yolinux.com/TUTORIALS/LinuxTutorialPPP.html presents a selection of methods for establishing a PPP
connection for Linux
B. For Windows XP and 2003 computers, follow the steps below to set up an advanced network connection between the
Windows computer, through its COM port, to the Console Server. Both Windows 2003 and Windows XP Professional allow
you to create a simple dial-in service which can be used for the Remote Desktop/VNC/HTTP/X connection to the Console
Server:
• Open
Network Connections
in Control Panel and click the
New Connection Wizard
• Select
Set up an advanced connection
and click
Next
• On the
Advanced Connection Options
screen, select
Accept Incoming Connections
and click
Next
• Select the
Connection Device
(i.e. the serial COM port on the Windows computer that you cabled through to the Console
Server). By default, select
COM1
. The COM port on the Windows computer should be configured to its maximum baud
rate. Click
Next
• On the
Incoming VPN Connection Options
screen, select
Do not allow virtual private connections
and click
