I have tried to use the TProcess example on Lazarus web site and it is
not working with some type of executable files. For example it is
working with 'ping' but not with 'ls' or 'dir'.
I have tried also with 'ssh' but I didn't had a passwordless setting
back then. Now I have a passwordless ssh. I will try again. Maybe it
works.

You run a program via SSH and then exit?
In my case I need to constantly read the output produced by TProcess
because my SSH session is not just running once and then finishes. It
continuosly produces output as I start new programs in it.

The example for TProcess shows ho to read the output directly from
memory via streams, but as I told you it doesn't work with 'static'
programs - programs that are genereting output just once and then exit
(like ls).
