Hi,

I am a newbie with ssh, but I tried to do exactly what is explained in
installation files or support files and I'm still stuck.

I've got 2 Win2k boxes.

192.168.0.6 is a ssh server and 192.168.1.124 is a ssh client.

Every times I'm trying to connect the server, I've got this message :

"C:\>ssh grdep@192.168.0.6

The authenticity of host 'intranet (192.168.0.6)' can't be established."

Private/Publis Keys are manually made for user "grdep" and 192.168.0.6 and
192.168.1.124.

In the homedir of user "grdep" are the files "authorized_keys2" with
information about 192.168.0.6 and 192.168.1.124, and "known_hosts" with the
same information + host nemes and IP addresses separated by a comma.

I think this is correct, but it still doesn't work.

I don't know what to do else,

So, if you can help me, i will really apreciate.
