Secure Connection to your enterprise network


Secure Shell (SSH) is a security mechanism provided on Unix and Linux servers which, amongst other features, enables remote users to use the internet to connect securely into their company's network.

Psion have tested the use of MindTerm's java-based SSH client on the netBook product range and this document provides some notes on how to install and use the client.


SSH works by connecting through a secure tunnel to the SSH server running within the private network on a Linux or Unix machine. You will need to be able to install and start this service before the SSH client can connect.


The MT.SIS file provided should be run. This can be done on a PC if the netBook is connected via PsiWin 2.3, or you can copy the MT.SIS file to the netBook and run it from there.

Configuration of SSH

As this is a java application that takes its commands from the supplied text file (MT.TXT), it is necessary to alter this. This is best done on a PC using an text editor program, such as Notepad. The example below sets up tunnels for Email and intranet browsing.

The format of this file is :
java mindbright.application.MindTerm [options]

Where [options] should include all of the following:

-server [Public IP address of SSH server (ie. Linux machine)]
eg. -server

-usrname [your username on the SSH server]
eg. -usrname johnsmith

-password [your password on the SSH server]
eg. -password opensesame

Depending on which services are required, one or more of the following options should also be included. These will set up a secure tunnel for POP3 mail (port 110), SMTP mail (port 25) and general web browsing (port 80). Any other ports can be set up in the same manner.

-local0 [unused local port:name of POP3 server:110]
eg. -local0

-local1 [unused local port:name of SMTP server:25]
eg. -local1

-local2 [unused local port:name of web server:80]
eg. -local2

The following text file is built from the previous examples

mindbright.application.MindTerm -server -usrname johnsmith -password opensesame -local0 -local1 -local2

Save the completed MT.TXT file into the folder \system\apps\MT\

There is a full description on how to use the command line options in the README.TXT file that is installed in the folder \system\apps\MT\

For a full description of SSH go to the many web sites on the subject.

EMAIL Configuration

  1. Within the netBook EMail program, create a new account using Tools\Add new account
  2. Under "Account", set up your name and company EMail address
  3. Under "Outgoing", set the SMTP server to localhost
  4. Under "Incoming", set the POP3 server to localhost, and mailbox login and password to your normal company EMail login and password
  5. Select the "Advanced" button <Ctrl-A> and set the SMTP port to 9001 and the POP3 port to 9000 (as set above in the MT.TXT file).
  6. Press "OK" to save these account details. 


Web Browser Usage

Once the necessary tunnel (probably Port 80) has been created then all browsing to the secure site needs to be prefaced as "localhost". So, in the above example, call up as localhost/index.html

Linux Setup

Assuming that SSH has been installed, type sshd to start the service.

If SSH has not been installed, see your Network Administrator.
