So long story short, starting with Xenial you have the possibility to install "isc-dhcp-client" which doesn't include the 2 extra port bindings, but if you need it for Dynamic DNS (DDNS) you can optionally install "isc-dhcp-client-ddns".
On Trusty, "isc-dhcp-client" combine both, and AFAIK, I don't think the SRU process will allow the source package to be re-designed just like Xenial to add this new binary package "isc-dhcp-client-ddns" in Trusty archive, since this according to me falls under a feature request more than fixing a bug. -- 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
