Does anybody know a good book, online course, tutorial etc. about the internet protocols (HTTP, SSH, E-Mail). Or generally about the underlying network technologies?
I have access to the ex-safaribooksonline (now learning.oreilly.com).
There’s a course called TCP/IP by Ric Messier.
and this book which teaches network programming ( you need to know some C): https://www.amazon.com/Effective-TCP-IP-Programming-Programs-ebook/dp/B001V7U69Q/ref=sr_1_1?ie=UTF8&qid=1541431737&sr=8-1
Can not vouch for it but its on my list to consume…
