Hi,
there is a bug in libnss-myhostname that prevents "ping6 $(hostname)" on
machines with ipv6 enabled, but only link-local addresses configured:
http://bugs.debian.org/705900
This is biting the debian-edu default installation, and the debian-edu
team has asked me to propose the fix for wheezy.
The real cause for the issue seems to be in glibc (although there is
disagreement between libnss-myhostname’s upstream and other people), but
a simple work-around can be employed in libnss-myhostname, by letting it
ignore link-local addresses. The fix is uploaded to unstable, and the
debdiff attached.
Is this ok for wheezy? If so, how should I proceed -- wait for it to
enter jessie and then upload a package, built in a stable chroot, to
s-p-u?
Greetings,
Joachim
