But for iwpan, it seems that there is no such option. I need to run some experiments with fakelb driver and hope that I can move wpan devices to different network namespaces. > > Would you please let me know whether there is a workaround or I miss anything? > Netns support doesn't exist mainline now, but I have patches. I created them where bluetooth-next was behind net-next for netlink u64 pad patches. I need to clean them up and send them mainline. kernel: https://github.com/linux-wpan/linux-wpan-next/commits/netns wpan-tools: https://github.com/linux-wpan/wpan-tools/commits/netns the hwsim starting script from website (updated): --- #!/bin/sh # we need some Private Area Network ID panid="0xbeef" # number of nodes numnodes=6 # include the kernel module for a fake node, tell it to create six # nodes modprobe fakelb numlbs=$numnodes # initialize all the nodes for i in $(seq 0 `expr $numnodes - 1`); do ip netns delete wpan${i} ip netns add wpan${i} PHYNUM=`iwpan dev | grep -B 1 wpan${i} | sed -ne '1 s/phy#\([0-9]\)/\1/p'` iwpan phy${PHYNUM} set netns name wpan${i} ip netns exec wpan${i} iwpan dev wpan${i} set pan_id 0xbeef ip netns exec wpan${i} ip link add link wpan${i} name lowpan${i} type lowpan ip netns exec wpan${i} ip link set wpan${i} up ip netns exec wpan${i} ip link set lowpan${i} up done --- creates 6 phys and 6 wpan interfaces with a lowpan interface, each of them in his own net namespace. btw: I want to mark fakelb deprecated and add a new implementation of fakelb with the name "mac802154_hwsim", I hate it when I told about the "fakelb" driver and wireless people told me "do you know hwsim...". It's simple the same stuff but somebody named the stuff completely different which makes no sense. I also don't know if we really should add the netns support flag for wpan-phy's. This is for HardMAC transceivers only, there exists one outside but we currently support SoftMAC transceivers currently only. :-) I hope I could help you and now I try to bring these patches mainline since already people want to do experiment like me which is great! - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
