Wireshark (previously called Ethereal) is an open source and cross-platform packet capture and network analysis application. It is probably the most popular tool of its kind and has many uses. You can install Wireshark without needing to restart or log out, which makes it great to debug a live problem that's hard to recreate. You can download Wireshark from https://www.wireshark.org/, and it runs on Windows, Mac, and Linux.
