Hi Jazz,
I don't find it necessary to run dhclient as a daemon. My server has two
interfaces, one wired and one wifi. In my /etc/rc.conf:
ifconfig_fxp0="DHCP"
ifconfig_ndis0="WPA DHCP"
[You might recognise ndis as the Project Evil driver for using Windows
network drivers under BSD.]
When the netstart script runs, those two lines have the effect of
starting wpa_supplicant on ndis0, and running dhclient on both interfaces.
Supposing I temporarily assign a static IP to fxp0, I can revert to DHCP
by typing:
$ sudo dhclient fxp0
which does some DHCP magic and gets a lease.
If I take ndis0 down I find I have to run /etc/netstart again to get it
back up, but you didn't want to know that.
