What gives: grep -R IFLA_INET6_ADDR_GEN_MODE /usr/include/ Without this, the IPv6 handling is a bit limited, but should still mostly work. > NetworkManager[2751]: <info> (can0): new Generic device > (/org/freedesktop/NetworkManager/Devices/0) > NetworkManager[2751]: <info> (can1): new Generic device > (/org/freedesktop/NetworkManager/Devices/1) > NetworkManager[2751]: <info> (eth0): link connected > NetworkManager[2751]: <info> (eth0): new Ethernet device > (/org/freedesktop/NetworkManager/Devices/2) > NetworkManager[2751]: <info> (lo): link connected > NetworkManager[2751]: <info> (lo): new Generic device > (/org/freedesktop/NetworkManager/Devices/3) > NetworkManager[2751]: <info> startup complete > NetworkManager[2751]: <info> ModemManager available in the bus > NetworkManager[2751]: <info> (ttyUSB2): new Broadband device > (/org/freedesktop/NetworkManager/Devices/4) > NetworkManager[2751]: <info> (ttyUSB2): device state change: > unmanaged -> unavailable (reason 'managed') [10 20 2] > NetworkManager[2751]: <info> (ttyUSB2): modem state 'connected' > NetworkManager[2751]: <info> (ttyUSB2): device state change: > unavailable -> disconnected (reason 'none') [20 30 0] > > root@beaglebone:/etc/NetworkManager/system-connections# > root@beaglebone:/etc/NetworkManager/system-connections# > root@beaglebone:/etc/NetworkManager/system-connections# > root@beaglebone:/etc/NetworkManager/system-connections# nmcli con add > type gsm con-name ali ifname ttyUSB2 apn m2minternet.apn > > root@beaglebone:/etc/NetworkManager/system-connections# > NetworkManager[2751]: <info> keyfile: add connection > /etc/NetworkManager/system-connections/ali (d14ba871-2179-4e8e-82bc- > bb053c9c6ee9,"ali") > NetworkManager[2751]: <info> op="connection-add" uuid="d14ba871- > 2179-4e8e-82bc-bb053c9c6ee9" name="ali" pid=2760 uid=0 > result="success" > NetworkManager[2751]: <info> Auto-activating connection 'ali'. > ** > NetworkManager:ERROR:nm-exported- > object.c:293:nm_exported_object_class_add_interface: assertion > failed: (object_property != NULL) That is strange. Can run NM in a debugger, like # gdb /usr/sbin/NetworkManager > run --debug --g-fatal-warnings and show the backtrace. Btw, if you happen to recompile NM, please favor 1.2-beta2 (1.1.91). Thomas
