[DKIM Failure] Re: unknown subnet for client address

[Mehmet Ali Öksüz]

Hi Simon,

another strange thing;

Feb 17 10:26:15 aurad02 dhcpd: DHCPREQUEST for 194.27.24.18 from 
00:1b:78:ef:ae:13 via eth1
Feb 17 10:26:15 aurad02 dhcpd: DHCPACK on 194.27.24.18 to 
00:1b:78:ef:ae:13 via eth1
Feb 17 10:26:15 aurad02 dhcpd: DHCPREQUEST for 194.27.24.18 from 
00:1b:78:ef:ae:13 via eth1: unknown lease 194.27.24.18.

client wants to IP address, seems dhcp server gives an IP address, but 
it maybe doesnt write lease file.

thank you.
