Delete leases from dhcpd.leases when remove a subnet from dhcpd.conf

Hi all!

I'm configuring DHCP server using dhcpd. When I remove a subnet from dhcpd.conf file, the leases of that subnet still in the dhcpd.leases file.

Is there any parameter in the dhcpd.conf file tell the dhcpd delete leases from dhcpd.leases file when their subnet is removed from dhcpd.conf.

Thanks!

I am not aware of and didn't see a command in the documentation to flush the leases file. The file is typically appended and the old, inactive leases typically remain with it being normal to see multiple entries for a particular host. The entries don't hurt anything. though if it really bothers you, you should be able to go in and manually delete them. You may want to stop the DHCP server before editing the file and then restart it afterwards.
