Hello Dear Sven and Linus:
You are right , and When icheck /sys/class/net/bat0/mesh/* and i found archlinux lost network-coding .
No, they/you just haven't compiled network coding for batman-adv. And you don't need it.
They were connected via a single cable as you .What about the rest mentioned in my other mails?
Whether i need use older batman version (batman-adv and batctl 2015.2 ) ?No. Use a recent version (unless you know that this is a regression).
and our version is newest version ( Linux alarmpi 4.4.26-1-ARCH ) and hardware platform is raspberry pi B , but i search wiki , i found kernel 4.4 will usebatman 2015.2It just means that kernel 4.4 includes (more or less) batman-adv 2015.2. You can still use batman-adv 2016.2 as external module for this kernel version.
[...]
if batman-adv don't support archlinux really , whether ubuntu will support batman-adv .Hm? This doesn't make a lot of sense. batman-adv doesn't require special distribution support. It is just a Linux kernel module. You have to find out what other things (hw/drivers/tc/iptables/...) are causing the problems on your system.
And I even know of people that use Arch Linux on their Freifunk supernodes together with batman-adv.
Kind regards, Sven
