Ok I looked into this some more, and found the cause. The fix is here : https://github.com/webmin/webmin/commit/f27277c4eb7bdb1ba0d4a91890858951601b3faaThis will also be included in the next Webmin release.

Just for additional information, I have 2 other DHCP servers serving other specific parts of our network running the same Oracle 8.8, Webmin 2.021, ISC DHCP 4.3.6 which work fine. Granted they have far fewer devices to support. On Wed, Jun 14, 2023 at 1:15 AM Jamie Cameron <jca...@we...> wrote: Thanks for those! Does the 159.218.43.117 lease appear when you click on List Active Leases on the main page of the DHCP server module? There's also a button on that page to show expired leases as well.. On 13/Jun/2023 04:59 Buchanan, Ted <tbu...@vi...> wrote .. Hi Jamie, thank you for responding. I have copied from the terminal 4 leases from the /var/lib/dhcp/dhcpd.leases file -- the first 2 leases (159.218.146.157 and 159.218.147.8) were taken from non-contiguous sections of the lease file and are visible when in Webmin I click on the 159.218.144.0 network and then click the List leases button. The next 2 leases (159.218.43.117 and 159.218.42.219) were copied from the same dhcpd.leases file and are not visible in the Webmin lease listing. Below that I have copied the appropriate sections from the /etc/dhcp/dhcpd.conf file. I can not say exactly when this problem made itself known or what change may have triggered it.

The issue may be that Webmin isn't parsing the file properly.. On 12/Jun/2023 11:05 Buchanan, Ted <tbu...@vi...> wrote .. I'm running Oracle Enterprise Linux 8.8 as a DHCP server with ISC DHCP version 4.2.6-46 (from the Oracle distribution). I'm running webmin-2.021 to help with the administration of this server. Everything used to work/display just fine but suddenly, when trying to list the dynamic leases within a subnet, I get the message, "The DHCPd lease file /var/lib/dhcpd/dhcpd.leases does not contain any leases that are active at the current time." If I click on the List all active and expired leases button, I get the message "The DHCPd lease file /var/lib/dhcpd/dhcpd.leases does not contain any leases." Clearly, when I use a text editor on the /var/lib/dhcpd/dhcpd.leases file, all the leases exist, new clients receive new IP addresses and existing ones are able to renew successfully. The leases that _DO_ show up are from wireless subnets or subnets not directly connected to our campus. I'm not the only one who admin isters this server/service so the Webmin module is really helpful and currently missed. Any suggestions for troubleshooting and correcting this issue. Everything in the /etc/dhcp/dhcpd.conf file agrees with the current operation.
