DHCP uses FFFFFFFF16 to represent an infinite lease. Try if it's

supported.

Anyway, it's insane value as year lease time :)

Hi,

I m looking for the max value for max-lease-time. would 512640 seconds (1 year) work?

Thanks . Götz

why not configure reservations for those access points?

the downside of a really long lease time is if you have to change something like DNS, gateway, whatever, the clients with a really long lease will not 'see' the change until 50% of hte lease time expires as thats the default refresh.

Hi, what do you mean with "reservations"? the APs in question just need an IP for connecting to the managemnt server which is in the same subnet.

a DHCP reservation is when you convert a lease to a static reservation, so each time that MAC/identifier asks for an IP, you give it one thats preconfigured. typically you can just cut/paste an entry form /var/state/dhcpd.leases into /etc/dhcpd.conf and tweak it to something like...

host myhost { hardware ethernet 00:01:08:00:ad:33; fixed-address 192.168.0.249; option host-name "myhost"; }

or if you're clever write a bit of perl to do that automatically,
