ssh into raspberry without a router (lemmy.ml)

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!

This is neat solution, you'll lose the laptop WiFi internet access though.

You can set the pi to connect to the phone WiFi by editing files on the SD card (using your laptop)

No, your laptop also connects to the hotspot. If you have available wifi at your location, you can then setup the pi to use that wifi and disconnect the phone hotspot, and just use the local wifi on all devices.

Ive just found this to be the simplest setup. I briefly had serial over bluetooth set up, and it was an easier way to change the pi's wifi, but it broke pretty quickly for me not sure why.

Probably the most elegant solution is ethernet over usb, but thats a bit of a pain to set up.

For me a hotspot has been the least headache
