The RJ45 connector has components inside the shell that must be present. You cannot direct wire the Ethernet from board to board. A proper CAT5/6 cable must be used.
I planned on using CAT5/6, but no RJ45 port.
I also was talking on ##networking from @freenode.net and they are saying that I should use pins 8 and 10 (https://pinout.xyz/pinout/serial_pi_plus
# ) which are serial pins. On top of that, there was somthing about PPP, RS232, and Ethernet standards I could use. From my understanding, there are electrical protocols that I would use, and the internet protocol would sit on top of the electrical protocol that I choose. Not finished talking to these people, so I'm still gathering more info.
PPP is a software protocol, Point to Point Protocol, most often used as PPPoE, Point to Point Protocol Over Ethernet. RS-232 is a serial communication signalling standard. Ethernet comes in a variety of forms. The original form used a network backbone of 1" coaxial "cable". (I put the scare quotes on cable because the outer conductor of that is a solid Aluminum tube.) What you now think of Ethernet cabling is a point to point cabling system using unshielded twisted pair (UTP) with various "category" standards. Most common current ones in use are Cat-5, Cat-5e, and Cat-6. RJ-45 is the standard connector. (And for those not fully conversant with this stuff, the RJ-45 is an 8-pin connector that looks like the "big brother" of a 4-pin RJ-11 connector used for modular telephone cabling.) As already noted, the terminating connection for Ethernet over UTP is *not* just a simple. soldered connection.
So...what you have to decide is: What sort of physical connection do you want, and what sort of software stack do you want to run over it? As already mentioned, one of the simpler ones to set up is using TCP/IP over USB.
Probably the least expensive would be to use Pi0W boards instead of Pi0 and use the built-in wireless capability. That requires no extra hardware, and would be a cheaper solution than anything other than USB....and without the 5m cable limit.
