Hi, 
 
I'm agree with you, but I can connect from that HP-UX server from the
root account or from other user account. Also, I can connect as user
"Administrator" from my own PC with another OpenSSH client (using
Cygwin). So, the Riverstone 15K is configured to ignore the user. 
 
Regards. 
Carlos.

 <pre wrap="">Hi Carlos,

When you start the ssh client of OpenSSH without an explicit user. 
OpenSSH assumes that you have the same username on the connected server.

What you do in this case is connecting as "root". 

To verify this you can try to connect the "Riverstone 15K" when logged
in as a normal user instead of root. This should fail. If it doesn't
then maybe the Riverstone doesn't have any user management built in and 
simply maps all usernames to root.

Cheers

we use OpenSSH. Here you have what usage from an HP-UX server reports:

-----------------------------------------------------------------------------
root@server1[/]#ssh
Usage: ssh [options] host [command]

root@server1[/]#ssh -V
OpenSSH_4.2p1-hpn, OpenSSL 0.9.7i 14 Oct 2005
HP-UX Secure Shell-A.04.20.004, HP-UX Secure Shell version
-----------------------------------------------------------------------------

And we can connect to the Riverstone 15K without passing the username.

Kind regards.

   |Can you include in the library this case in which username is not needed?

According to the RFC[1] for SSH2 protocol, username must be sent.
Can you get accesses to that equiments by other SSH2 client, for example,
OpenSSH?  If you can, what kind of configuration are you setting?
