I'm writing a cut-down DHCP server implementation for a specific use-case. Rather than split off onto a private network for the development I'm running the server on a custom port (11167) and sending to a custom port (11168).
In order to test the system without needing access to the embedded client I'm using Ubuntu 11.04 running in Virtual Box.
I'm wondering how I can get
dhclient on the Ubuntu box to talk to port 11167 and receive on port 11168.
