In secure I see a unsuccessful sshd pam unix for user root as it then says session closed for user root.
But I just ssh in from my iPhone as root, but it says for pam unix session opened for user root by uid=0
I am sure a package update did it, but as to what I don't know. It does not appear a protocol issue as to why mostly I get a chance to enter root and password before the connection drops.
It's not password / auth issue and only from Windows. Next I try on my wireless as I am atleast on the LAN side, but then again ssh from my iPhone is over WAN.
I also checked ws_FTP and putty it's not dropping off due to changed or corrupted server ssh key either
