## hping

Purpose: Packet generator capable of doing quite a lot. In terms of troubleshooting, very useful to test
network latency where ICMP does not work.

Example : Test network latency from the container to a remote host on a specific port
```
🐳 → docker run -it --net container:perf-test-a.1.bil2mo8inj3r9nyrss1g15qav nicolaka/netshoot hping -S -c 5 google.com -p 80
