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!

    Thanks! That seems rather easy. Only thing I’m not sure about, I have basically only access to the pi over SSH. I could use a screen and keyboard but would prefer not to. What would happen if I configure the network wrong on the pi and can not connect anymore, even over my home network? Could I change the config by putting the SD card into my laptop and changing a file? Or is it possible to make it redundant, so if it can’t find a DHCP server, it automatically switches to the preconfigured settings you described? :) Thanks a lot

      I’ve never used a pi, but it should be possible to mount the root partition and edit the /etc/network/interfaces or /etc/dhcpcd.conf file, or /etc/NetworkManager/conf.d/* if you have NetworkManager (systemctl status NetworkManager to check).

      You should also make sure that sshd is listening for connections from any address (0.0.0.0 and ::).
