Yes sir..
Dynamic update value is set to true on both test.local and the reverse
zone.
Form what Robert mentioned I am looking at the install logs now.
So this is where DNS update is bombing:
2016-04-26T16:31:08Z DEBUG args=/usr/bin/nsupdate -g
/etc/ipa/.dns_update.txt
2016-04-26T16:31:08Z DEBUG stdout=
2016-04-26T16:31:08Z DEBUG stderr=; Communication with "Correct DNS
server IP"#53 failed:
operation canceled
could not talk to any default name server
That is weird, maybe do you have allowed TCP/53? It may try to use TCP
instead of UDP
And please check on "Correct DNS server" if there is any logged entry
about dynamic update from client (journalctl -u named[-pkcs11])

And this is where SSHFP updates are bombing:
2016-04-26T16:31:09Z DEBUG args=/usr/bin/nsupdate -g

2016-04-26T16:31:09Z DEBUG stdout=

So it looks like it can not talk to port 53 but nslookup is working
fine from the box and outputting the server response as the correct
dns ip which is in the logs
Server: correct IP of DNS server
Address: correct IP of DNS server#53
Name: dingle.test.local
Address: correct ip of dingle
reoslv.conf has 1st listing as the same ip as in the logs and nslookup
result.

Hi All,
Wondering if someone knows how the SSHFPs of a box are getting
uploaded to IPA during ipa-client-install
--enable-dns-updates? Is it going over port 389,636,22?
Have an issue that on one network my enrolls work fine and
everything gets updated. A new network was put in place but
still part of the same domain and I get SSHFP failed to
upload. I was assuming this has something to do with DNS but
Network team says bi directional port 53 is good and I can
nslookup. Both new and old networks point to the same IPA DNS
server for enrolling. The IPs of the new network still fall in
my reverse zone.
So My DNS is setup with:
test.local
10.in-addr.arpa
and the IP scheme for new net is 10.5.x.x, old net is 10.35.x.x
