Motivated to watch data exchange on Bitcoin Newtwork, especially on regtest, and with hints from David Harding I decided to analyse traffic on regtest with Wireshark.
I've installed and setup (I've got a list of interfaces) Wireshark and start capturing from all interfaces available and immediately run one regtest node with following connection specification:
... Bound to [::]:11111 Bound to 0.0.0.0:11111 ...
I put a
tcp.port==18444 filter (in the style of this description) and apply.
Problem: There's no traffic shown!
Question: What am I doing wrong and what interface should I capture from?
