On my second re-read of this thread I made my spot check and noticed " The proper fix is to have dhcpd open the leases file as user dhcpd during start and not root and having /var/lib/dhcp/ and the leases file belong to dhcpd:dhcpd. "
which implies (correctly) that dhcpd opens dhcpd.leases before dropping privileges, and also implies that maybe the ownership shennanigans are due to dhcpd's failure to open the leases file as the non-privileged user. This is done because, as things are currently structured, dhcpd initiates the failover relationships (which requires data from the dhcpd.leases file) at the same time as it opens the listening sockets (which requires privileges in the default configuration). There may also be other information dependencies that I haven't noticed yet. We're evaluating our options at this point. It will be helpful to know if the forcing of ownership to root:root of the files and directory are being done as an attempt to cope with dhcpd's behavior or if that is construed as a feature and the desired state. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1186662 Title: isc-dhcp-server fails to renew lease file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1186662/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
