I have two RPis that I'd eventually like to use for different things. I want to be able to use them both headlessly but I don't ever plan on having them plugged into my laptop at the same time when I do this.
I've only ever worked with them headlessly so far and they're connected to my laptop running OS X via an Ethernet cord. When setting up my RPis initially I messed up with the the static IP setting for the Ethernet and could not figure out the IP address of the RPi to login. I ended up editing the
cmdline.txt file to include
ip=x.x.x.x which finally allowed me to login to my first RPi.
My question: Could I do the same thing with the second Pi - assign it the exact same IP - so I don't have to keep changing the IP address for that connection on my Mac since I'm configuring my DHCP with a manual address?
Again, I'm not planning having them plugged into the laptop at the same time (cannot even if I wanted because of only one Ethernet slot) which I thought might make it okay. But if there are hidden problems I - as a total amateur here - am missing I'd appreciate being told so I don't mess up anything else.
