#38 libvncserver not accepting link local addresses
Hello,
I'm just adding IPv6 support to VirtualBox and when trying to bind to a link local IPv6 address (the fe80:: ones), I can see this error:
[X] orgasmatron: today root$ VBoxHeadless -s vmvboxdevel --vrde config

^C

When changing the address to a global one:

It's working. Bug or Feature?

Feature. For IPv6 link-local addresses, you have to specify a scope id as well - like fe80::5604:a6ff:fef1:73c6%eth0. See http://stackoverflow.com/questions/5746082/ipv6-link-local-address-format.
