Hi,
I am a newbie to the world of DHCP. I am not sure if I can
specify my problems appropriately. Here's a try:
I have copied "dhcpcd" to my root floppy of the Linux machine.
I have also made "/etc/dhcp" directory. I have edited the
/etc/rc.d/rc.inet1 and put "/sbin/dhcpcd" there.
When I boot the machine using boot/root floppy, this line
doesn't give any error but it doesn't recognize the ethernet
interface either. It seems it is not able to connect DHCP server.
On the contrary, a windows machine on the same network when booted
can get IP address from the DHCP server (meaning that server is working
fine). I have configured server to give IP addresses based on hardware
addresses of the clients.
Could anyone please let me know if "dhcpcd" needs any other files,
or any configurations to be able to run. Please explain from the
point of view of a boot/root floppy system. I want my clients to
be able to get IP addresses from the DHCP server based on their
hardware addresses, whenever they are booted using boot/root
floppy.
----
I also compiled DHCP client on a linux machine by using "make"
and "make install". This linux machine already has an I.P.
address. If i run "dhcpcd" here, it also exits ( i think it
is supposed to stay as a daemon). I did an strace on it and
the results are :

Can anybody kindly let me know why it exits.
I will be highly thankful for any help.
