But if you are going to "forward only;" you can use TSIG
with 9.4.2 and secure your communication paths. You will
stop being a open recursive server by default. When BIND
9.4.3 is finalised you can upgrade to it or to BIND 9.5.2.
The -P1s (and the upcoming -P2s) are stopgap measures until
the betas stabilise. They work for most sites most of the
time however for large sites there will be more hand tuning
involved potentially retuning the kernel to return more
Named has gone from using a small number of descriptors to
using potentially very large numbers which will exceed the
system's ability to supply them. The problem is to work
out good strategies to deal with the problem. We are working
on how to deal with the issue without making the security
picture worse or degrading performance though it may come
down to making a choice.
