Currently (without this SRU), existing Trusty users will have DDNS-by-default dropped on a release upgrade to Xenial. Users who still need it would need to install isc-dhcp-client-ddns manually, which is acceptable in a release upgrade. This is a good thing for security, and so should continue to happen, right? If you get all users automatically receiving isc-dhcp-client-ddns in this SRU, then subsequently the users' behaviour after upgrade to Xenial will change. They will continue to have isc-dhcp-client-ddns installed, and so won't get the benefit of this improvement. > And for users bother by the extra random port they will simply have to > apt-get purge isc-dhcp-client-ddns. This part sounds like it'll work well then, but I'm not sure about the change in release upgrade behaviour above. In comment #20, you said that there doesn't seem to be a way to disable DDNS at runtime in Trusty. But this is presumably based on the upstream-shipped build configuration. How difficult would it be to do by patching the code? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1176046 Title: isc-dhcp dhclient listens on extra random ports To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1176046/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
