[systemd-devel] systemd-resolved fails without IPv6

[Michael Olbrich]

Hi,

Without IPv6 systemd-resolved fails to start with:

Failed to start manager: Address family not supported by protocol

strace tells me this is the errno from socket():
[...]
socket(PF_INET6, SOCK_DGRAM|SOCK_CLOEXEC|SOCK_NONBLOCK, IPPROTO_IP) = -1 EAFNOSUPPORT (Address family not supported by protocol)
[...]

I think this is from manager_llmnr_ipv6_udp_fd().

Is IPv6 now mandatory, or should this be fixed?

Regards,
Michael
