Is it possible to assign DHCP IP for client for 5 interfaces at one shot?


I have a RHEL Machine. All I have is 5 Ethernet cards.
I want all of them to be assigned IP through DHCP while I boot my system.
Is it possible?

Sure its possible if you have a DHCP enabled Gateway and Dhcpd clients configured. Are you using an ISP's Gateway/Router/Modem are you wanting to configure one of your computers as to provides these services? Do you have a static or dynamic public address?
Given the information provided: You want to setup a home or LAN
network and share your internet connection. Not a problem. You can use DHCP or Masquerade with static Private Network IPs and just configure the pc1 as dhcp client.

Here is link for masquerade: http://tldp.org/HOWTO/IP-Masquerade-HOWTO/

Look at the link. It obviously has an extra http:// at the beginning. Remove it, and the link works fine.

How can you setup WHAT? The 'office desktop', or a DHCP server?

If you want the NIC's to get a DHCP address, configure the NIC to get one when you're building the system. Since you're using RHEL, you've got access to the RedHat knowledebase, since you're paying for it. Google also has many articles on how to set up NIC's in RHEL. RedHat has "system-config-network", so if you run that, you can set up your NIC's to use DHCP, instead of static addresses.

If you need to build a DHCP server, again, there are many how-tos on it.

Actually,the RHKB is still open to the public.
@OP; here's a typical cfg file for DHCP ethernet card eg /etc/sysconfig/network-scripts/ifcfg-eth0
Code:
DEVICE=eth0
HWADDR=<put MAC address here in hex format>
BOOTPROTO=dhcp
ONBOOT=yes
Type=Ethernet
repeat for another 4 files ie eth1-4
