getifaddrs: Address family not supported by protocol Calling ip addr fails with the following error message: Cannot open netlink socket: Address family not supported by protocol My use case is running a docker raspberry pi arm container on Ubuntu 14.04 x64 with qemu-static. My steps to reproduce are the following: # docker pull philipz/rpi-raspbian:latest # docker run -it --rm -v /usr/bin/qemu-arm-static:/usr/bin/qemu-arm-static philipz/rpi-raspbian bash root@3b4ddc174279:/# ip addr Cannot open netlink socket: Address family not supported by protocol A fix or an workaround would be awesome. note: we are also working with a embedded arm distro which has no package manager available, would be nice if the workaround would not depend on apt-get We got netlink sockets working for linux-user over the course of 2016, and "ip addr" now works for me with a 32-bit arm chroot. This should be fixed in QEMU 2.10.
