< 5.Configure installation networking
< <The new -r11+ boot CDs allow you to configure a working network, allowing you to use ssh, scp or wget < as needed before even beginning the installation process. Even if you don't need to do these things now, < you should go ahead and set up networking now. Once set up, Portage will be able to use your configured network < once you are inside the chroot environment (required for installing Gentoo Linux).
< << Network configuration is simple with DHCP; If your ISP is not using < DHCP, skip down to the static configuration section below. <
<< Code listing 4: Network configuration with DHCP |
< # dhcpcd eth0 < |
< Note: < Some ISPs require you to provide a hostname. To do that, < add a -h myhostname flag to the dhcpcd command line above. < |
If you receive dhcpConfig warnings, don't panic; the errors < are most likely cosmetic. Skip down to Network testing below.
< << We need to setup just enough networking so that we can download < sources for the system build, as well as the required localhost interface. Type in the following commands, replacing < $IFACE with your network interface (typically eth0), $IPNUM < with your IP address, $BCAST with your broadcast address, and $NMASK < with your network mask. For the route command, replace < $GTWAY with your default gateway. <
<< Code listing 5 |
< # /sbin/ifconfig $IFACE $IPNUM broadcast $BCAST netmask $NMASK < # /sbin/route add -net default gw $GTWAY netmask 0.0.0.0 metric 1 < |
Now, it's time to create the /etc/resolv.conf < file so that name resolution (finding Web/FTP sites by name, rather than just by IP address) will work.
< << Note: At the moment the only editor installed by default is nano, a < small and very easy-to-use visual editor. Use nano with the -w < option to turn off automatic line-wrapping. < |

<< Code listing 6: /etc/resolv.conf template |
< domain mydomain.com < nameserver 10.0.0.1 < nameserver 10.0.0.2 < |
Replace 10.0.0.1 and 10.0.0.2 with the IP addresses of your < primary and secondary DNS servers respectively.
< <Now that your network has been configured, the /sbin/ifconfig -a command should show (hopefully!) < that your network card is working < (look for UP and RUNNING in the output). <
