Hi! I hope this is the right community to ask.
Next week I will be on the road for 5 Days for work. I have quite some spare time, so I thought I would dig up my raspberry project again and hopefully finish it.
I need it with me, because it controls some hardware, so a VPN to home does not work. So only option I could think of, is to connect the pi directly to my laptop via an ethernet cable. As far as I understood from some research is that I would need to install and run an DHCP server on my laptop, which they did not recommend. Alternatively they suggested to just take a router and plug both devices in there. I don’t really have a spare router, so that’s not an option either.
To be hones it confuses me a little, that there does not seem to be a standard for connecting to a device directly over a single cable and login with a user account.
Any recommendations how I can work on the pi like with ssh?
Thanks a lot!

Most modern NICs can auto-negotiate the Rx/Tx circuits on either kind of cable, but I’m not sure about RPi.
Only one device needs to be able to negotiate it.
Just about everything made in the last 20 years is capable of doing this.
If I remember correctly, 1000Base-T standard has a requirement that device has to negotiate pinout on the fly. No matter which pin is connected to which. Obvioiusly just randomly wiring a cable up has other problems, like signal-to-noise, but in theory it should work even if you make a cable that’s as unstandard as you can make it.
That’s amazing. I would love to see the algorithm for that. Hopefully I’ll find a nice explainer if I search around.
