Hijacking programs' using socket(s) / a proxy in python



Currently I'm attempting to read/send UDP(/TCP) packets a running process is receiving and sending. So far I figured out several methods:


Normal:
Program <-> socket <-> Destination

Proxy:
Program <-> socket <-> proxy <-> Destination

Socket hijack:
Program <-> socket <-> Destination
^ | ^
| v |
+---"Shared" Socket ---+
Python



A Proxy would be possible but the ports change on startup and detecting that would be a pain.



So I reasoned that it would be possible to get some kind of copy/reference of the socket of the running process so that I could use that socket to read/send packets in python.



Edit: To clarify my question:
How would you get a python socket that is a "copy" of a process' socket.





And the question is...?

Hystrix command on request collapser fallback

Image
Clash Royale CLAN TAG #URR8PPP Hystrix command on request collapser fallback I have a scenario where I want to apply hystrix on the fallback (and process one-by-one) of a hystrix request collapser's batch method. The fallback method ( processEntryBatch_fallback ) is invoked. But the hystrix command ( processEntryBackup ) in turn the fallback invokes is not reported (doesn't even appear on dashboard). And the fallback method ( finalFallback ) is not invoked either. I would like to know what am I missing here ? I referred javanica documentation processEntryBatch_fallback processEntryBackup finalFallback @Service public class DummyService private static final Logger log = LoggerFactory.getLogger(DummyService.class); //batch processing method public void processEntry(List<String> msg) //batch processing throw new RuntimeException("Exception while batch processing"); //processing one-by-one @HystrixCommand(fallbackMethod="finalFallback") public ...
