Hi Alan, I tried doing an "dhclient -s <ip addr of the dhcp server> <interface name>" from a RHEL physical linux box [that exists in the same VLAN as my cobbler server with dhcp enabled on it], and I could see the /var/log/messages being updated for DHCP discover, DHCP OFFER, DHCP Request, DHCP ACK etc. This eliminates any possibility of network issues [as far as I can see].
However, when I boot up this same physical box [pxe already enabled in BIOS], I do not see any requests reaching out to cobbler server. Please advise, if anything amiss is here and how it can be resolved.
The physical box has only one network interface? If there are multiple nw interfaces, make sure you are testing netboot with the same one you tested with dhclient.
If you execute dhclient without specifying -s parameter (server IP address), it also works? Doing that will broadcast the DHCP request and that is what will be done during netboot.

Thanks Alan.
The physical box has multiple interfaces however the pxe boot is enabled only for that interface that is in the same Vlan as cobbler server. The Mac displayed in the bare metal console is the same being used for "dhclient" interface.

I see. What about my other previous question? If you execute dhclient without specifying -s parameter (server IP address), it also works?
