[Babel-users] Error when running babeld

[Callahan, David (US)]

Thanks for the info Antonin,

I don't want IPV6 on the system.

Looks like it is enabled with disabled set to 0.

How do I disable it?

Thanks
Dave.

Hi!

As the error reports, there are no link-local IPv6 address on the interface eth0.
ifconfig should report something like this:

    net0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
            inet 192.168.1.15  netmask 255.255.240.0  broadcast 172.23.47.255
            inet6 fe80::xxxx:xxxx:xxxx:xxxx  prefixlen 64  scopeid 0x20<link>

You can check that IPv6 is enabled on your system with

    sysctl -a | grep disable_ipv6

or check your network configuration.
