Konrad,

This is because the F-Secure client uses 3 protocols within the main
SSH protocol.

1. Connection Protocol
2. Authentication Protocol 
3. Transport Protocol

The connection protocol handles the multiplexing of sessions and
forwarding through the transport protocol. This can also be seen when
creating new port forwards after already being connected, you don't
need to restart your session for the port forwards to be established.

I'm not sure if the other clients have this ability.

As a workaround you might want to look into using the ssh-agent and
keypairs within OpenSSH client to get a transparent login and second
session to your server.

HTH,

Nathan Jackson

I use PuTTY all the time, in Windows and to get a duplicate session,
you click the top-left icon in the window (I forget what this is
actually called) and select 'duplicate session'.



Yes, that is true - but in PUTTY you have to input credentials 
(username/password)
and on the server new sshd will be forked for you - but in F-Secure ypu simply
get independend shell without need to log in.
