DHCP Question

[ccgius]

I am a novice in Linux.  The computer running Debian connects to the router (Linksys 4 port. Model #: NR041).   [The router connects to the DSL Modem.] It connects to the Ethernet Port.  I have enabled DHCP in the Router.    How do I install DHCP Client?   What should be the content of this file?   I have 2 NIC cards in my computer iconfig -a should list the all the eth  - however it doesnt.   Is there a way I can have it to identify both the NICs?   What happens after the DHCP Client is installed?   What do I have to do for it to connect to the Internet?     Thanks & Regards,   AARON ROY Austin, TX
