Re: [B.A.T.M.A.N.] Alfred 2016.1 bind errors

alfred explicitly binds to the link-local IPv6 address of the interface since version 2016.0. I suspect one of the following caveats might be your problem:

• The link-local IPv6 address must match the MAC address of the interface

(here bat0) (derived by flipping the 2 bit of the first byte, and adding fe80 and fffe); this ususally breaks when the MAC address is changed after the interface is up

• The link-local address must not be tentative when alfred is started

(duplicate address detection must have finished; this usually means that the interface must be up for 3 seconds before alfred is started)

This took care of it. I had IPv6 disabled via sysctl and once enabled it started working. Here is the list of commands I entered to get a graph:

modprobe batman-adv batctl if add eth0 ip link set up bat0

alfred -i bat0 -m & batadv-vis > mesh.dot

Thanks for the help!
