| 1) I think you did try "dhcpcd eth0" as a root..
2) If your router gets the IP from your ISP does it then provide some sort of NAT or NAPT? In otherwords all computers behind it have a ip address of range 192.168.* or other NAT variations.. It is possible that your router provides a dhcp service to the computers behind it. I might even say most likely so.. depends of course on your router config.
3) If you want to use a static ip, then add something like this to your /etc/conf.d/net:
iface_eth0="192.168.1.100 broadcast 192.168.1.255 netmask 255.255.255.0"
gateway="eth0/192.168.1.1"
Of course change the IP addresses to match your network. Then just add the eth0 to your bootup sequence. In otherwords type "rc-update add eth0 default" as root. |
