This article describes a procedure for investigating a technical issue with network connectivity for Pomfort support.
To investigate issues with the connection to your LUT box, you can record the network traffic between your LUT box and Livegrade
On the command line, you will have to use the following command:
sudo tcpdump $FILTER -B 524288 -w ~/Desktop/network.pcap
Replace $FILTER with the appropriate filter for your LUT box:
- BoxIO:
port 18181(e.g.sudo tcpdump port 18181 -B 524288 -w ~/Desktop/network.pcap) - Teradek Color:
port 54440 - AJA FS-HDR:
port 8 and host $IPADDRESS– replace$IPADDRESSwith the IP address of the AJA FS-HDR, - (e.g.
sudo tcpdump port 8 and host 192.168.10.15 -B 524288 -w ~/Desktop/network.pcap) - Cobalt:
port 9002 - ARRI cameras:
port 5055 - Canon monitor:
port 5000 - RED cameras:
port 1111 - Sony F65:
port 8888 - Varicam:
port 49152
Please make sure that only the affect device is connected while capturing the network traffic.
You can stop the network Capture by pressing Ctrl+C. After the network capture has stopped you can send the file network.pcap on your desktop to support.
