I have searched for answers to my problem , but come up empty handed.
The problem is that when using scp into a certain machine (Solaris 2.7
running openssh_3.6.1)scp fails. It appears to work, i.e. fills the
line with #'s (not the status line) and the file is never at the
destination machine. Some background info, the machine was running an
older version of ssh/ssl. I have just upgraded these two packages, but
still have the same problem. I also have tcpd running, however I can
ssh in from the same machines without a problem. The problem is only
when trying to scp to that machine. When scp'ing from this machine to
other machines it is OK. I have also upgraded another machine solaris
machine with the same version open ssl/ssh, but get the same problem,
thus I dont think it is related to a particular version mismatch of ssh.
I have captured some debug in the hope that someone can help. machine1
is the problem, fails with incoming scp from another machine
