Issue
I'm running foo.py
on Ubuntu box A, and I want to feed its stdout
as stdin
to bar.py
running on Ubuntu box B.
I think python foo.py | /dev/udp/12.34.56.78:1234
will send out of box A to box B, but how can I pick up the packets and feed them into bar.py
?
I need something like udp_listener localhost:1234 | bar.py
but (if that's correct) what's the actual syntax?
Solution
On your Ubuntu box B, run
nc -klu -p 1234 | cat
On your Ubuntu box A, run
echo "Hello world" > /dev/udp/12.34.56.78/1234
If this works, replace cat
with bar.py
and replace echo "Hello world"
with python foo.py
You may need to open firewall for boxB:1234/udp
