Thanks for your answer - what IP addresses do I require in /etc/hosts ? My file only contains localhost

comment Unable to get embedded device to ping anything on the network
@goldilocks Im a developer, but the desktop variety so debugging embedded stuff is pretty new. I am not getting a core dump as I built everything without debug info for compactness of the system. I think as a first resort I will roll back to an earlier busybox version and if that doesn't work go at it the hard way. I will upload the full segfault message when I return to work

It is not really a distribution as such, it is buildroot. It creates kernel, cross compilers and rootfs for an embedded device. All the ip , ippaddr etc is done via busybox which is also built with buildroot.

@vonbrand So basically its an incorrectly configured network?

I have not built strace as part of the embedded setup - I will do so ASAP. ip addr show also crashes, but ip link list displays output without crashing. I will update the question with the output as its too large to write here.

Thanks for your answer. Is there an easy way for me to find out if /etc/fstab is being used by my setup? I am not an expert in linux unfortunately.
