I just noticed that I got
option dhcp-lease-time 60;
in dhclient-wlan0.leases when booting an FC3 box from my wireless router. This very short lease time may have caused various problems I've had with the network lately.
Now, I thought at first this was a router issue, possibly related to a firmware upgrade I did a few days ago, but now I'm not so sure as:
1. It turns out that if I put
send dhcp-lease-time <value> ;
in /etc/dhclient.conf, I will actually get the lease time
specified in <value>, i.e. the DHCP server seems to be prepared to
give me whatever lease time I ask for (at least as long as the
request isn't entirely outrageous.)
2. It turns out that my latest "yum upgrade" installed a new dhclient
version...So, what lease time will dhclient request by default? Or won't it request anything at all? (Maybe it has to request *something*?) Has the behaviour changed lately?
