netopeer could not creat socket

[Alex-Wong]

when I start netopeer-server, some error occurs as shown belown:
netopeer-server[25485]: sock_listen: could not create socket (Address family not supported by protocol)
netopeer-server[25485]: Server is not listening on any address!

It seems "::0" is not a correct ipv4 address(my system does not support ipv6):

Hi,
this should be easy to fix. If you look at the ietf-netconf-server model included in netopeer, you can see that there are two ways of specifying the address the server listens on. Either with a single port node, whose value determines only the port to listen on (all interfaces, "::0" are all IPv4 and IPv6 interfaces) or by a list of pairs of address and port. So if you (manually) edit netopeer startup configuration and set address to "0.0.0.0" and port to "830", netopeer should listen on all IPv4 interfaces.

Regards,
Michal
