SSH for Windows

SSH for Windows

Download and install SSH for Windows

TSSH has been upgraded to 1.5.4

There is no SSH version 2 client freely available for Windows.

The two public domain clients I could locate are SSH version 1, so a compatibility with SSH version 1 is needed on the server.

Robert O'Callahan's version of SSH client

The goods and the bads

TTSSH is based on an existing Telnet client: Teraterm Pro
Tera Term supports Japanese language
Automatically updates the database of public keys for known hosts
Source is available
No RSA key generator
Needs to modify C:\autoexec.bat to disable rhost autentification (see below)

Download TTSSH

It comes in 2 files:

Tera Term Pro
TTSSH New version 1.5.4

Install and configure TTSSH

Uncompress ttermp23.zip in a temporary directory
Run setup.exe from the temporary directory.
It will install Tera Term Pro in C:\Program Files\Ttermpro
In C:\Program Files\Ttermpro uncompress the file ttssh13.zip
Use the Secured client that is located in C:\Program Files\Ttermpro\ttssh.exe

Note: You should not use the default icon created on the Windows desktop, this icon is a shortcut to the NON-secured version of Tera Term Pro. Make sure to use the secured version as mentionned in point 4. above.

Note: TTSSH is written to use a privileged port (under 1024).

If the local network filters out privileged ports (in order to disallow rcommands for example) TTSSH has to be setup to use non-porivileged port (above 1024). This is done adding the following line to C:\autoexec.bat:

SET TTSSH_DISABLE_RHOSTS=1

Authentification with rhosts will not be enabled anymore.

Cedomir Igaly's version of SSH client

The goods and the bads

RSA key generator is available
Does not automatically update the database of public keys for known hosts (see below)
Source is not available
Strange behaviour setting the DISPLAY environment variable (see below)
No installation procedure
Strange defaulting of user name (see below)

Download SSH client

Get the file ci98274.zip

Install and configure SSH client

Create a directory to install SSH client
Uncompress ci98274.zip in that directory

Note: you have to edit manually the file known.hosts in the installation directory:

From the server you want to connect to, get the file /etc/ssh_host_key.pub
It will look like:
```
1024 37 14523456789[...]093357 root@ai3gate.cs.ait.ac.th
```
On the PC, add the followin line to the file known.hosts:
```
ai3gate.cs.ait.ac.th 1024 37 14523456789[...]093357
```
Note that the syntax of the file has slightly changed. Here ai3gate.cs.ait.ac.th is the host you plan to connect to. If you define a fully qualified name in the file known.hosts, you then have to use a fully qualified name to make the connection.

Note: when the option X11 format is selected, the environment variable DISPLAY will be automatically set on the sheel on the remote machine.

As a result, when you are trying to use some programs that check the variable DISPLAY to modify their behaviour (for example emacs) they will hang.

Note: (this may be linked to our local configuration) we are linked to a Novell server where my user name is ON (upper case), so SSH was offering me to connect to the remote machine using that as user name, while the account on Unix machine is on (lower case), I did lost quite some time on this stupid mistake, searching for some tricky protocol error.
