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

[Buchanan, T. <tbu...@vi...>]

No, 159.218.43.117 does not appear on the main page List active leases
button, nor does it appear in the subnet List leases.  When I click on the
List all active and expired leases button, I get "*The DHCPd lease file
/var/lib/dhcpd/dhcpd.leases does not contain any leases."*
