After getting carried away coding at the SDN workshop this week I've gone and flashed an RB750 with the latest openwrt (chaos calmer), and discovered that the package/dependency management lacks the finesse of something like debian/ubuntu: root(a)OpenWrt:~# opkg install openvswitch Installing openvswitch (2.3.1-0dfed4ba9c8a16a1f316d709b7831a4e139472d4) to root... Downloading http://downloads.openwrt.org/snapshots/trunk/ar71xx/mikrotik/packages/packag.... Collected errors: * satisfy_dependencies_for: Cannot satisfy the following dependencies for openvswitch: * kmod-udptunnel4 * kmod-udptunnel6 * * opkg_install_cmd: Cannot install package openvswitch. digging deeper, it appears that kmod-udptunnel is built for ar71xx/nand (https://downloads.openwrt.org/snapshots/trunk/ar71xx/nand/packages/base/) but not for the mikrotik fork (https://downloads.openwrt.org/snapshots/trunk/ar71xx/mikrotik/packages/base/) questions: - has anyone got this running? im going to build kmod-udptunnel from source and then opkg install openvswitch, but was hoping i wouldn't have to - does anyone have a preference for ar71xx-mikrotik over ar71xx-nand? i know Dean has deployed ovs from source on older mikrotiks running attitude adjustment, who else is playing in this space? cheers sam
