hi all i ran a few times in troubles with iproute an rtnetlink or netlink_dev with newer kernels. i.e. i can compile and recompile the kernel and iproute (all from sources)... and as soon as i like to add a route to a tunnel: ip route add 192.168.0.0/24 dev gre_tun i get: rtnetlink no such device. ip link / ip addr is showing the tunnel (also ifconfig). i assume, that the kernel doesn''t support this feature or that iproute is not ready for this kernel. i also experienced troubles with other newer kernel. last known working kernel is 2.6.13. i didn''t find any infos about which kernel is working (iproute tested against it) or any explanation about this. before i try something impossible and wasting more time, i ask you for some hints. regards, moritz
