Gordon, I would turn on some debugging here. Instead of "ssh linuxb" do "ssh -v linuxb" or even "ssh -v -v linuxb" and see where things are going wrong.

I have two SLES8 Linux servers running under z/VM 4.3, LINUXA and LINUXB. I cannot do a SSH connection from LINUXA to LINUXB. linuxa:~ # ssh linuxb 1714: Connection closed by UNKNOWN 1. There is nothing in the /var/log/message file about this. 2. Both are running SLES8. 3. Both are set up to use ssh protocol 2. 4. Both servers have the other server set up correctly in /etc/hosts and /etc/hosts.allow 5. This used to work! 6. I can successfully "telnet linuxb" and "ftp linuxb", so communications are working. 7. I can successfully "ssh linuxc" where linuxc is functionally identical to linuxb. 8. All the rpc PIDs and sshd appear to be working. 9. known_hosts and authorized_keys2 appear to be set up properly. What the heck does "Connection closed by UNKNOWN" mean? Where am I going wrong? Use the Best! Linux for Servers Macintosh for Graphics Palm for Mobility Windows for Solitaire. Gordon W.
