Re: [webmin-l] [EXTERNAL] Re: Webmin DHCP module does not show all leases in dhcpd.leases file

[Jamie C. <jca...@we...>]

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..

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.  Thank you for any direction you can give.  lease 159.218.146.157 {  starts 2 2023/06/13 10:56:13;  ends 2 2023/06/13 11:56:13;  cltt 2 2023/06/13 10:56:13;  binding state active;  next binding state free;  rewind binding state free;  hardware ethe

Can you send a sample of the dhcpd.leases file that contains the leases that aren't showing up? The issue may be that Webmin isn't parsing the file properly..

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.
