problems when opening an ssh session

Hi All,

I have an account on a Solaris 2.6 machine in which the administrator has installed SSH 3.2.0. Then I have 2 Solaris 2.8 machines (for which I am the administrator) in
which I have installed OpenSSH versions 3.4p1 and 3.5p1 respectively.

Now if I open a connection from the SSH 3.2.0 client to the OpenSSH 3.5p1 server everything works properly, but if I open a connection from the SSH 3.2.0 client to the OpenSSH 3.4p1 server I get (from ssh -vvv):

debug: Connecting to pma.iso.vilspa.esa.es, port 22... (SOCKS not used) debug: Ssh2/ssh2.c:2297: Entering event loop.

and it doesn't proceed to the next line, which should be:

debug: Ssh2Client/sshclient.c:1421: Creating transport protocol.

So I can open an ssh session with the 3.5p1 server but not with the 3.4p1 server.
Could anybody please give me a hand with this problem ?
