Hi,

After some assistance from the NT server support guys, it appears that the public key that I have sent them is in the wrong format (there's a KnowledgeBase article, ID 31930, posted on the ssh support website about key incompatibity) - according to one article, the following command should be run:-

Now that you have uploaded the public key to the OpenSSH server, you must convert the public key format from SecSH (the format generated by the F-Secure SSH client) to OpenSSH (the format supported by OpenSSH servers). To do this, follow these steps:

1. On the command line, change to the .ssh directory in your user account.
2. Use the following command to convert the key to OpenSSH format and append the key to the authorized_keys file. Replace publickeyname.pub with the name of your public key:
ssh-keygen -i -f publickeyname.pub >>authorized_keys

My questions on this are:-
1. On which server is this meant to be run - the Unix or Windows?
2. It mentions .ssh directory, whereas the Windows server has a .ssh2 directory.
3. Is there a utility I can run this on the Unix server before transferring it to the Windows server. The options that I have are:-

bash-3.00$ ssh-keygen -help

Usage: ssh-keygen [options] [key1 key2 ...]
Where `options' are:
-b nnn Specify key strength in bits (e.g. 1024)
-t dsa | rsa Choose the key type.
-c comment Provide the comment.
-e file Edit the comment/passphrase of the key.
-p passphrase Provide passphrase.
-P Assume empty passphrase.
-?
-h Print this help text.
-q Suppress the progress indicator.
-1 Convert a SSH 1.x key. (not implemented)
-i file Load and display information on `file'.
-D file Derive the private key given in 'file' to public key.
-B number The number base for displaying key information (default 10).
-V Print ssh-keygen version number.
-r file Stir data from file to random pool.
-F file Dump fingerprint of file.

Does anyone have any further input on this that may help me?

Thanks in advance,

Steve
