Hello,
in our lease file I found consecutive lease entries for the same MAC
address with two different IP adresses. The first one has no
instructions for the dns registration and one vendor-string. The
second has the dns information and a completely different vendor-string.
The machines are thin clients ( old PCs ) that start from a intel
bootable bios and then load thinstation.
Can anyone please tell me why dhcpd ( ancient V3.0rc4 ) give two
different IP addresses even if the MAC is the same ?
I know that we should migrate, but found no documentation on how to
migrate the lease file ( AFAIK the format changed )
Thanks
Andreas
