I don't know specifically what skills you're interested in, but this is all pretty much networking fundamentals.

I think I learned most of what I'd need to do this in 'TCP/IP Illustrated: Volume 1'.

There's plenty of "network penetration testing" type books which might also be of interest, though I don't have a specific recommendation here.

There's a wider set of books at https://github.com/jacobian/infosec-engineering that's pretty good too, though it's a wider set of things than this.

Excellent, thanks! Just took a look at "TCP/IP Illustrated: Volume 1" and was exactly what I was looking for. Any book along those lines that is compressed/water down (just to get started over a weekend)?
