How can I find out what variables and their values were provided by a dhcpd server to my client?
I thought perhaps /etc/dhclient-eth1.conf, but that is not the place...

Try /var/lib/dhclient/*.leases.

Check the lease file in /var/lib/dhclient

what values? You can see most parts of the negotiation on the server in real time. dhcpd logs by default all requests and the answers to messages.

I have a proprietary firewall that provides dhcpd services and includes fields for entering the WINS server address and the WINS mode. I wanted to see what these variables show up as as well as their values...
I do not see them in cat /var/lib/dhclient/dhclient-eth1.leases on this system.

How is dhclient being invoked?
ps afxww | grep dhclient

On this system it is run from a script in a terminal window where I also run wpa_supplicant (NetworkManager does not work well enough on this system). On a FC10 system, I use NetworkManager and it invokes dhclient.
Neither show the address of the WINS server, nor the WINS mode (H-mode).

Ah, I ask because the -lf argument to dhclient should point to where the lease file is generated. For example, on one of my systems:

I don't think any dhcp client will cache any values that it won't use, and a linux server doesn't usually need a wins server or the wins mode. Use a Microsoft client and look at the values there.
