Hello Ronen,
I currently have a working set consist of PI and MMDVM software connected to the arduino running on the AMPRNET but the Pi dont support IPIP
I don't understand why you say this when I have a standard Raspbian image running on AMPR w/o any special kernels, etc. I can share with you a simple script I put together that enables the AMPR, ampr-ripd, and then pings a few known hosts that I know work for me.
Is it more easy just to add the IPIP support for my Image ? (please dont tel me "get this and this and compile" as I dont know to compile But if it is only to install something with simple command i can do it )
I would argue that adding IPIP won't be difficult though I do it within the Linux OS side of things. If you want to terminate the tunnels into JNOS, that will take someone else's help. Btw, If you can follow instructions on how to configure MMDVM and JNOS, I'm quite confident you can follow instructions to compile things. :-) It's not hard but it takes more time to install some of the tool chains, etc.
