You need to make sure of what your drivers are first. Once you've determined the correct driver you'll need for your NIC (ethernet card) you need to make sure it's installed:
If it's not, run
This should install the module/driver for you. Once that's done, make sure you've got all your ISP information handy (primary and secondary DNS IP addresses, domain server name, DHCP server name if needed, DHCP server IP address if needed). You won't need any DHCP info if you have a static IP. Then run:
Answer the questions with the correct ISP information and you should be good to go. After you run your netconfig, I recommend a reboot (ifconfig eth0 up
should work, but it didn't for me--neither did dhcpd
). A reboot should set your dhcp daemon into action and have it request an IP from the DHCP server (assuming you have a dynamic IP and not a static). You should be online at this point. Hope this helps.
