PPP DHCP client

[Gonzalez, Pedro - ACD]

Hi,
I need to run DHCP over a PPP interface.
The PPP interface between my 2 devices is up and running, and my
application calls for the client (Linux) to be assigned an IP address
via DHCP.

I tried to evoke the dhcp client over the ppp interface as shown below,
I see that the system is sending DHCP discover messages, however they
are not making to the wire since I don't see them on the Sniffer.

The following is the output of launching the "dhclient" command in
Linux...

[root at icb ppp]# dhclient ppp0

DHCPDISCOVER on ppp0 to 255.255.255.255 port 67 interval 4
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

As per output above, it looks like PPP0 is not being recognized, and the
program "dhclient" is listening and sending the messages on /LPF/ppp0
instead of PPP0.  Can I fix this problem by modifying any of
configuration files on my system, and if yes, which files do I need to
modify?


The following is my system's software build...

[root at icb ppp]# uname -a
Linux icb 2.6.11-1.1369_FC4 #1 Thu Jun 2 22:55:56 EDT 2005 i686 i686
i386 GNU/Linux


Thanks,
