Hi,

I've recently updated to Fedora 10, and found out that ssh doesn't work with a Ubuntu server. When I tried to ssh the server, the connection is closed. Is there anyone who can help me on this? Thanks.

I'm sure that server is all right. I can ssh to other machines, and then ssh to that server. I even could ssh from that server to my local machine. However, once I tried to ssh that server, the connection could not be setup.

I've already tried install openssh to the latest version manually, and closed the SElinux. Nothing works.

Here is the log:

~]$ ssh 128.138.*.* -v
