Today I updated on Ubuntu, got isc-dhcp-server V4.4.1-2.2ubuntu6.1 and now isc-dhcp-server complains about "Can't clone pool group". > > I found that I can put the pool declaration outside of the subnet declaration on Ubuntu, and it works correctly. Unfortunately, doing this on RasPiOS fails! Having a pool outside of a subnet isn't a valid config. It may appear to work, as do some other config errors, but may cause some really "interesting" issues. > Am I totally using subnet and pool incorrectly, or is this an incompatible change in isc-dhcp-server? And, is it an intended change coming to mainline isc-dhcp-server or did Ubuntu bork it? I'd be thinking that there's something changed in the Ubuntu version. Can you roll-back to the earlier version and try it again ? Simon _______________________________________________ ISC funds the development of this software with paid support subscriptions.
