a valid however sometimes hindering policy at work is that remote server ports are not available in user space.
I only found the following solutions which (probably, as I didn’t try them all) won’t work.
e.g. when using rsync with -e and ssh -J it results in
channel 0: open failed: administratively prohibited: open failed
stdio forwarding failed
ssh_exchange_identification: Connection closed by remote host
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: unexplained error (code 255) at io.c(235) [Receiver=3.1.2]
so i need a way that will not require a port but only use stdin
