What causes Org-protocol capture HTML to fail?
If a page lacks an HTML title, the string passed to org-protocol would have nothing where the title should go, and this would cause the capture to fail. Now the bookmarklets will use [untitled page] instead of an empty string. (No Elisp code changed, only the examples in the readme.)
How does a packet capture library work on a computer?
The packet capture library receives a copy of every link-layer frame that is sent from or received by your computer. Messages exchanged by higher layer protocols such as HTTP, FTP, TCP, UDP, DNS, or IP all are eventually encapsulated in link-layer frames that are transmitted over physical media such as an Ethernet cable.
How are Zettels digitalized in org roam?
At the corner of each note, Luhmann ascribed each note with an ordered ID, allowing him to link and jump between notes. In Org-roam, we simply use hyperlinks. Org-roam is the slip-box, digitalized in Org-mode. Every zettel (card) is a plain-text, Org-mode file.
Why do you need a protocol hierarchy in packet analysis?
Generating a protocol hierarchy provides useful information about the contents of a packet capture based on the protocols in use. If you have adequate protocol knowledge this should naturally lead to questions that help you zero in on the answer you seek, or at a minimum, filter out things you don’t need.
How to capture a link to a web page?
After installing the bookmarklets, you can select some text on a web page with your mouse, open the bookmarklet with the browser, and Emacs should pop up an Org capture buffer. You can also do it without selecting text first, if you just want to capture a link to the page.
How to create a protocol hierarchy in Wireshark?
My favorite method for understanding what protocols may be present in a capture is to generate a protocol hierarchy chart. You can generate a protocol hierarchy chart in Wireshark by selecting the Protocol Hierarchy option from the Statistics drop-down menu. This chart provides a list of protocols observed in the capture.
