Hi
Did you use YaST Firewall to allow the Secure Shell Server to open the
ports? What SLE version?

Hi
So are you using the command line of a GUI eg nautilus?

So if you connect vi command line with some debug, can you post the
output;

sftp -vv username@host

Please put the output around cod tags or on pastebin and post back the
URL (You might want to edit any security related items, ip address
etc).

Hi
Is there an existing .ssh directory in /root?

I see in (SLES 11 SP1);

# sftp -vv root@127.0.0.1

Your OpenSSL is at version a, SLE11 SP1 is at h, not sure if this may
be causing an issue or the RSA keys.
