Who or what decides the length of a dhcp lease?
I notice that the computers accessing my desktop dhcpd server
have widely different lease times.
The laptop I'm currently using, for example,
has a lease time of about half-an-hour
according to /var/lib/dhclient/dhclient-eth1.leases:
-----------------------------
renew 2 2008/1/29 13:08:12;
rebind 2 2008/1/29 13:34:10;
expire 2 2008/1/29 13:41:40;
-----------------------------
But the server sets the time much longer,
according to /etc/dhcpd.conf on my desktop:
-----------------------------
default-lease-time 21600;
max-lease-time 43200;
-----------------------------
Can the client change the lease times?
Or is it entirely up to the server?
[My grand-daughter's Wii seems to have an even shorter lease time,
at least it exchanges DHCPREQUEST/DHCPACK with the server every 2 minutes.]
Is there an online document that will instruct me on this?
