It turned out that this was because my hop limit was set to zero: # sysctl -a | fgrep eth0.hop_limit net.ipv6.conf.eth0.hop_limit = 0 which in turn seems to have been cause by a known problem in the network manager: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756534 https://bugzilla.gnome.org/show_bug.cgi?id=737252 Since this has already been fixed in the GNOME project, can Ubuntu 15.04 please take the upstream fix?
