The problem I see with real IPv6 support is that the current code doesn't=
really configure what address it listens on. As you can see in=20
iscsi_sock_bind(), it binds to INADDR_ANY.

So to get address families right, you probably need to explicitly=20
configure the portals with either numeric IPs or DNS entries. Then=20
getnameinfo() will set you up. You'd also need explicit support in the=20
SendTargets response code to answer back the right stuff. And don't forget=
that numeric IPv6 addresses need the [] syntax.

This is probably something someone else could help with. At this level,=20
it's just a standard network server/daemom implementation issue (like=20
getting named or ntpd to listen on specific ports, etc.).

Take care,
