Hi everybody,
Issue 1:
Thanks Ruben about your link.
I downloaded and re-used rpm from powerdns repo for el7. It is the same
with rpm that I yum from my centOS.
After I installed new dnsdist-1.0.0-1pdns.el7.x86_64.rpm again. I tried to
test encrypt:
> testCrypto()
Crypto not available.
All rpms suggested from Oli:
dnsdist-1.0.0-1pdns.el7.x86_64.rpm
dnscrypt-proxy-1.6.1-3.el7.x86_64.rpm
libedit-3.0-12.20121213cvs.el7.x86_64
libsodium-1.0.5-1.el7.x86_64.rpm
luajit-2.0.4-3.el7.x86_64.rpm
protobuf-2.5.0-7.el7.x86_64.rpm
re2-20160401-2.el7.x86_64.rpm
systemd-219-19.el7_2.13.x86_64
systemd-libs-219-19.el7_2.13.x86_64
I tried to read code from powerdns github, I guess "ifdef HAVE_LIBSODIUM"
returned "false".
I uninstalled dnsdist-1.0 rpm then I installed
"dnsdist-1.1.0-0.1.beta1.1pdns.el7.x86_64.rpm". It returned result:
> testCrypto()
Everything is ok!
Is it a bug of DNSDist with Redhat 7.2? I hope new dnsdist-1.1 will be
release soon.
Issue 2:
Thanks Winfried and Theodore !!
After I applied your suggestion, It works properly (as my expectation).
I'm still not clearly. If my DNS server manage multi zone such as: zone1.com,
zone2.com, zone3.com, Will I add as below ?
newServer{address="192.168.88.27:5353", qps=10, order=1, checkName="
zone1.com"}
newServer{address="192.168.88.27:5353", qps=10, order=1, checkName="
zone2.com"}
newServer{address="192.168.88.27:5353", qps=10, order=1, checkName="
zone3.com"}
newServer{address="192.168.88.33", qps=10, order=2, checkName="zone1.com"}
newServer{address="192.168.88.33", qps=10, order=2, checkName="zone2.com"}
newServer{address="192.168.88.33", qps=10, order=2, checkName="zone2.com"}
Some example from dnsdist README, newServer are always "up" without
checkName. I tried to install DNSDist in a system no DNS and one newserver,
downstream still "down". Can you help me clarify about it?
Kind regards,
Thao Nguyen
