#9 Bonding to a IPv4 address fails

[Anonymous]

It appears bonding balance to a IPv4 address fails on our Ubuntu Feisty host. Details below:-

I solved this by simply commenting out the following part in balance.h:

sockoptoff = 0;
status = setsockopt(srv_socket, IPPROTO_IPV6, IPV6_V6ONLY, (char*) &sockopt$
if(status < 0) {
perror("setsockopt(IPV6_V6ONLY=0)");
exit(EX_OSERR);
}

and then recompiling. I have not had any trouble with this until now.

This can also be solved by using 'localhost' instead of '127.0.0.1', like so:

$ balance -b localhost 9200 192.168.1.18:9200 192.168.1.22:9200
