This is a follow on from the NetCat basic
I am trying to do some Spark development I wrote my Server to generate data - but wrote it using UDP Broardcast Which at the time seemed a clever thing to do.
However when asking Spark Stream to connect to the UDP stream I have found that by default it only connects to a TCP Sock stream.
The program broardcast.py sends text terminated with \r\n the format is UDP - port 50000 ip 192.168.1.255 (broadcast)
This data is collected via a UDP netcat command
The Output now piped through lv so I can check the data rates
The Output now passed into NetCat TCP Server - port 50001 TCP mode
Checked in a seperate process by reading port 50001 TCP from 192.168.1.215
And this looks like
python broardcast.py& nc -l -s 192.168.1.255 -p 50000 -u | \ pv | \ nc -l -p 50001& #check process #This should see TCP data on port 50001 nc -l -s 192.168.1.215 -p 50001
Very impressed with Netcat
