TightVNC includes the same bug which was reported for ssvnc (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774622). As the related source code is also identical, the fix given in that bug report also applies to package tightvnc.
Thanks for the report. Inguza Technology AB Sent from a phone Den 5 jan 2015 14:51 skrev "Stefan Weil" <sw@weilnetz.de>:
Control: tags -1 = wontfix Note in bug 774622: [...] Thightvnc is old software not supporting IPv6 at all. Upstream does not maintain Thightvnc on Linux any more. Thus, do not expect IPv6 support to show up in Tightvnc. Sven
