Re: Technical Documentation - CARP
Hi Jannick the man pages are also a good up to date source of information... sometimes a paper from a few years ago states something like X/Y is not supported... but as an OpenBSD developer once quiped "yes we do add features from time to time" :) so the papers can give really good context and insights... but refer to the manuals also to validate any improved syntax and or features Hope this helps Tom Smyth On Tue, 13 Apr 2021 at 09:34, jannick Weiss wrote: > > Hello,my name is Jannick Weiss and i am currently in the process of taking > my education as a datatechnician.

It's a bit wrong though, I noticed it says "encrypted" - it's authenticated but not encrypted. Doesn't go much into the protocol details either.

Googling "openbsd carp design" turned this PDF up, https://core.ac.uk/download/pdf/17210042.pdf from 2006 which perhaps dives a bit deeper. -- May the most significant bit of your life be positive.
Technical Documentation - CARP
Hello,my name is Jannick Weiss and i am currently in the process of taking my education as a datatechnician. As part of my education i have to do a presentation on a self-elected subject and i have chosen to talk about CARP. It is my understanding that it is you (OpenBSD) that have developed CARP. I am having trouble finding information about CARP, such as the different states the protocol goes through or how the election of the master node works specifically. If you can provide any documentation on CARP it would be greatly appreciated. In advance, thank you for any help you may provide. Best regards Jannick Weiss
