Creating persistent netcat link

I have a remote raspberrypi that uses autossh to connect to my local machine (with reverse tunnel -R). This should feed a dump1090 instance on my local machine. I'm using
/bin/nc localhost 40005 | /bin/nc localhost 30104
and it works great until the connection is good but when the link breaks the new connection isn't established. How can I make the netcat link persistent? Thanks!

Kind of a hacky option, but you could just wrap your nc
command(s) in a while
loop:
#!/bin/bash
while true; do
# your netcat command(s) here
done;
This'll keep re-launching the netcat stuff until you kill the script.

You might want asleep 1
in the loop too, to stop the loop running away on failure.

The main problem with this is that the netcat instance isn't killed when the link breaks, it just hangs.
