When a video is playing, run <b>tcpdump</b> or <b>wireshark</b> to verify it is playing locally.<br />
In either case, the above will show you what is the critical network traffic that you interrupt by unplugging the connection.

Yes, either of them. I prefer tcpdump, wireshark gives more detail than I usually want. You run run tcpdump in a command-line window.

Hi guys, <br />
<br />
We have a video music playout system, that essentially plays videos through firefox, it uses socket.io <br />
<br />
so basically nginx is setup on each machine and videos are played from client.domainname.net:9000<wbr /> and hosts files point client.domainname.net to 127.0.0.1<br />
<br />
so if we plug out ethernet out on most networks the videos will continue to play offline, however on certain networks if we plug &nbsp;out ethernet the videos will stop and it will be an issue with socket.io and as soon as we plug the ethernet back in, everything will resume playing again, even though its playing them locally

Socket IO disconnects hangs on certain networks
