Can you extract Fax from Packets?
Post Views: 92 This is a frequently asked question, especially from folks who troubleshoot fax in VoIP networks. Until today, I would have said “I have never seen it. That does not mean it can’t be done.” I also would have admitted that it is above my pay grade. But that all changed today. I
Extracting VoIP Packets from Multiple Captures
Post Views: 113 Let’s say you are a CO Tech/Engineer or an enterprise network engineer that works with Voice over IP (VoIP). Let’s further say that there are issues with one or more users so you have done a bunch of packet captures, perhaps even used Wireshark’s Ring Buffer capability, and now you want to
How to Set a WLAN Frequency or Channel in Linux for Wireshark Packet Capture
Post Views: 241 Learning how to manually control Wi-Fi channels in Linux is a foundational skill for wireless troubleshooting and packet analysis. Proper channel selection is critical because Wi-Fi troubleshooting is highly dependent on capturing the correct RF environment at the correct moment in time. When combined with Wireshark, Linux monitor mode provides one of
Apply Master to ALL Notes Pages in MS PowerPoint
Post Views: 4,382 Epiphany number 3,812!! After years and years of wondering what on earth is going on at Microsoft that they have done no feature changes of significance to PowerPoint, and frustration whenever I change the Notes Master, that I must go to every slide, one by one, and right click on the notes
A New Wireshark Welcome Screen
Post Views: 328 If you have upgraded Wireshark to the latest version 4.6.5 and later, you will note a big change to the “welcome” screen, or home screen of Wireshark. It now looks like this: The two “boxes” on the right are new and bold. The tips and tricks is great for new Wireshark users,
Humorous and April Fools Day RFC’s
Post Views: 3,266 OK – so this article is for entertainment of all us network nerds. Updated in 2026 As many already know, pretty much every year, the Internet Engineering Task Force (IETF) releases humorous RFC’s – jokes. Usually these happen on or about April 1st to commemorate April Fools Day. Without doubt, some of
IP Version Clarification and IPv8
Post Views: 596 I have seen a bunch of posts about IP version 8 supplanting IPv6. Let’s sort this out a bit. I think a full listing of the IP version numbers is needed as a backdrop. The Internet Protocol (IP) has evolved through a sequence of versions during its research, testing, and operational deployment
Net Neutrality at the Packet Level
Post Views: 307 Net neutrality is typically framed as a policy debate (see my background Net Neutrality post here), but its real implications are observable in packet-level behavior. For network engineers and broadband technicians, the question is not abstract: can you see evidence of blocking, throttling, or prioritization in a packet capture? Using Wireshark, it
Brief Evolution of Net Neutrality in the US
Post Views: 629 Net neutrality in the United States has evolved through a cycle of regulatory assertion, legal limitation, reclassification, repeal, and attempted reinstatement. It is not a fixed policy but a dynamic framework shaped by the intersection of law, politics, and network engineering realities. At its core, the debate reflects a fundamental tension. On
Does Windows support TCP CUBIC?
Post Views: 537 This question was sent to me in an email following my posts on regarding TCP CUBIC. The answer is Yes—Microsoft Windows does support TCP CUBIC, but the nuance is in how and when it’s used. For many years, Windows defaulted to Compound TCP (CTCP) rather than CUBIC. Meanwhile, Linux distributions standardized on
