No, socat works fine.  Otherwise I wouldn't be able to establish a
ssh connection at all.

Of course there is netstat, but my question was aiming for the
command on AIX that can be used in place of Linux' strace.

By the way, you seem to be misinterpreting the intention of my
mail.  I am *not* trying to solve the problem in our environment.
It is much too grave and too difficult to reproduce - we can not
rely on rsync at all in our system.  Instead, I am trying to help
the rsync developers to get this bug eventually fixed by providing
the requested information.
