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!

Does the raspberry pi have a wifi adapter, and is it unused for your project?

If so, you can use your pi as an access point

no need for cables, you just connect your laptop to the pi's SSID.

Downside is that now your laptop doesn't have Internet access, which may be a deal breaker (unless you can plug your pi into a router and get access through it). You could just get a cheap USB wifi dongle for your laptop and use one interface for Internet, one for pi.

Hostapd is probably how you would go about this of you're interested ( https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point/install-software )

Or they could connect their pi as well as their laptop to a hotspot created on their pocket computer masquerading as a phone. They won't lose their internet on the laptop or pi that way.
