Rereading carefully :) The above suggests you know the cause of the
difference in behaviour as to whether you use rsh or ssh with rcmd(). What
is it? I can't spot the difference.

dump : uses rcmd() to run "rmt"
rdist: uses rcmd() to run "rdist -Server"

Both use rcmd() which uses RCMD_CMD to start the remote program.

You find that dump doesn't work with ssh, I find that rdist doesn't work
with ssh.

What do ssh and rsh do differently? The remote program *is* started - Why
does it matter what was used to start it?

Cheers,

PS thanks to all for suggestions for workarounds eg rdist6, sdist..
