dhcpd - keep lease even if device sends expiration packet
 

I have a dhcpd server running CentOS and Webmin. I noticed in my lists of expired leases some of the lease times are only a few hours even thought I have lease length set to 1 week. I want to keep a lease for a week even if the device requests that it be expired. Is there some way I can do this in dhcpd?
I am attaching a screenshot of some of my lease times listed in Webmin.
Thanks,
Mike

How about just giving it a perm entry in DHCP ?

Static reservation
 

That won't work. I am not concerned with a particular client. Clients come and go. I want to be able to say for certain that a certain client had a certain address three days ago. If a client is able to expire his lease then I can't say whether or not someone else picked up that lease shortly there after and expired it as well.

In that case, it looks like you should be able to get syslog to log the lease changes http://linux.die.net/man/8/dhcpd and/or use the -d flag for dhcpd

Thanks.
 

Hmm... Yes, that makes a lot of sense. I will look in to that.
