possible to set nolisten on dhclient

[Andrew Nelson <freeandy@gmail.com>]

Hello,

I'm running a workstation that uses dhcp to gets it's ip address.  Everything
works fine but I'm hate open ports.  Is it possible to tell dhclient to not
listen on udp 68?

I have a firewall blocking the port already but like a say I hate open ports and
I don't think this one need to be open.

Thanks much
