vino-preferences does not report public IPv6 addresses

[Sander Jonkers]

Binary package hint: vino

Bug: vino-preferences does not report public IPv6 addresses, only IPv4 addresses.

On: Ubuntu 9.04 Jaunty Alpha 6

vino-preferences is now reporting: "Your desktop is only reachable over the local network. Others can access your computer using the address 192.168.2.150."

As vinage / vnc does now, as of Jaunty Alpha 6, correctly handle connections over Ipv6 (see https://bugs.launchpad.net/ubuntu/+source/vinagre/+bug/290394), vino-preferences should now also report (public) IPv6 addresses. Example of correct and expected behaviour:

"Your desktop is only reachable over the local network. Others can access your computer using the address 192.168.2.150.
Your desktop is reachable from Internet using Ipv6. Others can access your computer using the address 2001:838:1111::2222"

I think in vino-preferences.c the call dbus_g_proxy_call is taking care of finding out the IP addresses. I couldn't find out how to make that call dbus_g_proxy_call report back IPv6 addresses.

This bug is a serious security hole. Seeing the message "Your desktop is only reachable over the local network", people may think it is safe to allow access without a password or confirmation, but if their machine has global IPv6 connectivity, anyone on the Internet can take over their desktop. This is Not Good.

Still no mention of IPv6 by vino-preferences in 11.04 Alpha 2 daily updated. The text is still IPv4 only:

"Your desktop is only reachable over the local network. Others can access your computer using the address 192.168.178.24 or ubuntu.local."

... my public (and private) IPv6 address is still ignored by vino-preferences, while I can connect to the IPv6 address using vinagre.

So bug is still there.
