Want to inspect network activity or endpoints of a closed source binary or script that you don't understand? Try following on Linux: ``` strace -f -e trace=network -o /tmp/network_trace.txt /opt/foo.bin strace -f -e trace=network -o /tmp/network_trace.txt python3 /path/to/bar.py ``` Then you can view all network it made: ``` less /tmp/network_trace.txt ``` strace is nifty diagnostic, debugging, and instructional userspace utility for IT, cybersecurity or dev folks. See: ``` man strace ```
