Last post by deanwebb - June 29, 2025, 12:56:32 PMEnd to end means being able to track things in a system. In the case of TCP communications, it's confirmation messages. For UDP, as it does not have confirmation messages, then being able to detect breaks in the communication path will enable an administrator to determine if messages are being delivered or not.

Homework Help / Re: IP Address Exhaustion solv...
Last post by deanwebb - June 03, 2025, 07:52:07 AMNAT is a tricky thing, though. Used one time with the Internet connection, it is manageable. If it is used a second time for masking internal traffic, then problems develop. Problems multiply if address spaces are re-used in different areas and NAT is employed to mask the IP address re-use. This last scenario is common in industrial environments.
In the K3S cluster, how many nodes are being used? If the number is over 64K, then we may want to instead go with IPv6 instead of IPv4 with NAT.

Something like this could prove beneficial. I prefer academically written textbooks.

Last post by deanwebb - May 20, 2025, 03:42:01 PMThat's a subject list that reads more like a history of the topic. For example, PGP was popular some time ago, but has since waned as major email providers have implemented encryption.
The biggest area to know is how public-key infrastructure (PKI) cryptography works, and how it is different from symmetric cryptography.

This is the part of 20 subject syllabus for exam. It's subjective exam meaning answers are written instead of tick marks.
I am starting to learn this. What should I be learning in digital signatures? That benefit me in the long run as well as help me in exam? What about PGP? What practical scenarios can I implement on my own? Or is it left untouched because there're APIs that handle it for me these days? I'd love your insights on any of the topics.

Please do, my hacker friends are much interested in your network design and details.
