Endlich war es soweit: Das eigene Haus stand vor der Tür und Johannes hat sich um die Netzwerkverkabelung und das Netzwerkdesign gekümmert. Hier eine Zusammenfassung meiner Gedanken und deren Umsetzung – offen für kritische Rückfragen, Verbesserungsvorschläge und Bewunderungsbekundungen. :)

Capturing – because I can: IS-IS, GLBP, VRRP
I am constantly trying to add more protocols to the Ultimate PCAP. Hence I used some time in my (old) Cisco lab to configure and capture the following protocols: IS-IS, GLBP, and VRRP. And since Alexis La Goutte sent me some CAPWAP traffic, this protocol is also added. All packets are now found in another update of the Ultimate PCAP. Here are some details:

Adding some packets: RARP, SNAP, MPLS & More
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:

My Network Gadgets
This post is not about software but hardware tools for network admins. Which network gadgets am I using during my daily business? At least three, namely the Airconsole, the Pockethernet and the ProfiShark, which help me in connecting to serial ports, testing basic network connectivity, and capturing packets in a high professional way. Come in and have a look at how I’m working.
