The other day I just wanted to capture some basic Linux traceroutes but ended up troubleshooting different traceroute commands and Wireshark display anomalies. Sigh. Anyway, I just added a few Linux traceroute captures – legacy and IPv6 – to the Ultimate PCAP. Here are some details:
The other day, I was searching for a trace file with a decent protocol mix that could be used to introduce a few colleagues to Wireshark. This brought me to Johannes Weber and his Ultimate PCAP.
To get a first impression of a trace file, I used Wireshark’s protocol hierarchy – and boy, that’s a lot of protocols. This was not exactly what I was looking for: This single trace file holds snippets from 2014 to 2020 with a myriad of protocols and IP networks. Unfortunately, it’s nothing like the protocol mix found in a network analysis project.
Nevertheless, the trace file caught my interest as a long-time Wireshark user. After nearly 20 years of network analysis, I had my own collection of traces with a few odd frames. To my big surprise, I had recorded a few protocols that are not yet part of the Ultimate PCAP.
So here is my small contribution to this collection:

An updated version of the Ultimate PCAP is available. It features some more network protocols that I will depict in this blog post. It’s getting more special since the most common protocols were already in there. ;)
In the previous post, I released my Ultimate PCAP which includes every single pcap I had so far on my blog. But that’s not all: I have some packets in there that were not yet published up to now. That is, here are some more details about those (probably well-known) protocols. These are:
For the last couple of years, I captured many different network and upper-layer protocols and published the pcaps along with some information and Wireshark screenshots on this blog. However, it always takes me some time to find the correct pcap when I am searching for a concrete protocol example. There are way too many pcaps out there.
This is supposed to change now:
