Hi,
* new spice-server feature: add option to bind to a selected interface regardless of its addresses
How does that work?
I presume the client app would request listen=eth0, and the QEMU would have to call getifaddrs() to determine what IP addresses currently correspond to eth0.
Ah, so there isn't a direct way I'm not aware of, you still bind to a specific ip address (or multiple), just specified in a different way ;)
Note that supporting this isn't going to work with a single listening socket. Having ipv6 sockets accept ipv4 connects too works for wildcard sockets only. If you want listening on all ip{v4,v6} addresses of an interface you'll need a listening socket for each.
Yeah, I'm almost certain you'll need to have multiple listening sockets for this to work

Well, I've checked what my local dnsmasq does and it's doing precisely what you say: tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 29426/dnsmasq tcp 0 0 192.168.122.1:53 0.0.0.0:* LISTEN 29426/dnsmasq tcp 0 0 ::1:53 :::* LISTEN 29426/dnsmasq tcp 0 0 fe80::4c03:d0ff:fec2:aa7:53 :::* LISTEN 29426/dnsmasq In other words, dual-socket won't make dual-stack for selected interface possible without implementing https://bugzilla.redhat.com/show_bug.cgi?id=787256 anyway. :( David -- David Jaša, RHCE SPICE QE based in Brno GPG Key: 22C33E24 Fingerprint: 513A 060B D1B4 2A72 7F0D 0278 B125 CD00 22C3 3E24
