Lisa Bock reviews coloring rules and shows you how you can create a new color filter rule in Wireshark to customize your view to highlight specific field values, or protocol use when capturing traffic.
- When working with Wireshark,…you may notice that the traffic is colorized.…This has been done for quite sometime,…but if it bothers you, you can take it off…or modify the look and feel of Wireshark.…Up here under telephony,…you can take this and deselect the coloring rules…so that you have no color.…But a lot of us like the color…because it helps to identify potential problems.…We'll bring that back.…
As you can see here, some of these are black…and that might indicate a problem with latency.…In the lower right hand corner,…let's select the Wireshark expert information.…Here it's showing a lot of problems…with a potential bad check sum.…Well, that might not be a problem.…Let's take a look.…If I go up to this frame,…and I right-click,…and I take a look at protocol preferences,…and here it says, "validate the check sum, if possible."…I generally suggest you deselect this,…and that is because a lot of times…if the check sum is offloaded,…it's incorrectly calculated…and it appears to be an error.…
So that problem is fixed.…
