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! 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
Network interfaces can be assigned multiple IP addresses. You should be able to use DHCP and a link local address at the same time.
That said I think this is easier to do with network manager. I’m not sure how it works with the rpi. But “link local address rpi” is a good search term to start with.
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 ::).

Configure ethernet with fixed IPs, and configure wifi to use your phone hotspot.
Then you can use one to troubleshoot the other as needed.
Then your normal setup would be wired between the pi+laptop, with the laptop connected to local wifi for internet.
