[RFE] Backport RFC standard DDNS updates support from 4.3.5 ESV version
Last modified: 2018-04-10 04:01:58 EDT
Only "ad-hoc" and "interim" DDNS updates are available in the RHEL 7 dhcp-4.2.X. 4.3.5 ESV offer RFC standard DDNS updates (ddns-update-style standard; ) RedHat should rebase DHCP 4.2.X to 4.3.X ESV or give both legacy releases and the standard 4.3.X ESV one.
Hi Rupesh, can you please retest it with RHEL-7Beta compose? The patch is present there.
Hi, I have checked with customer. Unfortunately customer has stopped using DDNS. However they mentioned that they have read RHEL7.5 release note. They are closing service request.
