Gentoo Install

From CafeWiki

This Gentoo installation article is specified based on Sean's experience with the Kurobox. For sentimental reasons you may want to follow the instructions below, or if you want to save time, try the following howto - http://buffalo.nas-central.org/wiki/Install_The_2007_PPC_Gentoo

Telnet into the Kuro Box:

   KURO-BOX-EM login:    root
   Password:             kuroadmin

From expert mode set up the partitions:

   mfdisk –c /dev/hda

create 3 partitions such as the following hda1 20GB ext3 hda2 512MB swap hda3 remainder ext3

• Important note - set hda1 as bootable and write the output

format the partitions if necessary:

   mkfs –j /dev/hda1
   mkfs –j /dev/hda3
   mkswap /dev/hda2

mount the boot partition

   mount /dev/hda1 /mnt

Load up the expert binaries: ftp in using root, send the file EM_mode_binaries.tar.gz which came with the Kurobox from the console type:

   cd /
   tar –xvzf /root/EM_mode_binaries.tar.gz

Change directories to the mounted folder

   cd /mnt

Load the system: from the ftp session send in the system portage and snapshot bz files to the /mnt folder, you will need to download this from the Gentoo site. from the console type

   tar xvjf system-[version].tar.bz

Now you are ready to chroot into your system! From the console:

   mount –t proc none /mnt/proc

get the resolv.conf file

   cp –L /etc/resolv.conf /mnt/etc

now chroot!

   chroot /mnt /bin/bash
   source /etc/profile

set your terminal

   export TERM=vt100

Configure Portage:

   cd /usr
   tar xvjf /portage-[version].tar.bz2

get the overlay

   cd /usr/local/portage
   tar xvjf /overlay-[version].tar.bz2

Ensure that emerge works

   emerge metadata

This will take a while, so go have a coffee or telnet in for another session to continue on!

Setup user accounts:

   passwd [set the root password]
   adduser –md /home/<username> <username>
   passwd <username>  [set password]

Configure fstab:

In the etc directory ensure that the correct version of fstab is loaded, if not create one that looks like:

   # /etc/fstab: static file system information.
   #
   # <file system>     <mount point>     <type>     <options>                           <dump>	<pass>
   /dev/hda1           /                 ext3       defaults,noatime,errors=remount-ro         0 0
   Proc                /proc             proc       defaults                                   0 0
   None                /dev/pts          devpts     gid=5,mode=20                              0 0
   /dev/hda2           swap              swap       defaults                                   0 0
   /dev/hda3           /share            ext3       defaults,noatime                           0 0

Configure network:

   cd /etc/conf.d
   nano net

Using nano, create the following lines in the new net file using the ip address you choose

   iface_eth0=”192.168.100.29”
   gateway=”eth0/192.168.100.1”

now set your network config for startup

   rc-update add net.eth0 default

Set the hostname of the Kurobox, the example I use is mykuronas:

   echo mykuronas > /etc/hostname

From the /etc folder use nano to edit the hosts file so the localhost line looks like this:

   127.0.0.1     localhost     mykuronas

Set up sshd:

   /etc/init.d/sshd start

This will take a while as sshd generates its keyfiles, once it is done try out ssh then stop the service

   /etc/init.d/sshd stop

Now add ssh to the startups script

   rc-update add sshd default

Check that starup scripts are set:

   ls runlevels/default/

should return:

   local     net.eth0     netmount     sshd

Ready to reboot: Close all ftp connections and from the command prompt type:

   exit
   write_ok
   reboot

Now pray that it works!

If it comes up, this might be a good time to get emerge updates, first see what’s out there:

   emerge –puD system

To actually do the update:

   emerge –uD system

Then go away for many hours, if you leave it overnight you should be ok!

At some point you might want to set the correct timezone! Create a link to the timezone file in the system that matches your location.

   ln -sf ../usr/share/zoneinfo/Canada/Mountain /etc/localtime

*Optional Steps* Compiling a new kernel (example I use is for kernel 2.6.15 and I assume you have a working loader.o which I know is a big assumption): Untar into the /usr/src/ directory and apply the kernel patch

   tar –xvjf /[source-path]/linux-2.6.15.tar.bz2
   cd linux-2.6.15
   wget http://webpages.charter.net/trevorpowdrell/kurobox-sources-2.6.15.patch.bz2
   bunzip2 kurobox-sources-2.6.15.patch.bz2
   patch -p1 < kurobox-sources-2.6.15.patch
   cp ./config_kuroboxhg ./.config
   make menuconfig

In the menu, set bridge (networking -> networking options -> 802.11d Ethernet Bridging) and tap/tun (Device Drivers -> Network Device Support -> Universal TUN/TAP Device Driver Support) to modules, and save configuration Ensure that you have set the network device to the Realtek 81xx driver.

   make vmlinux modules modules_install
   objcopy -O binary vmlinux /boot/vmlinux-2.6.15-kurobox 
   cd /boot

Loading a new kernel

   sync
   insmod loader.o kernel=vmlinux-2.6.15-kurobox

Use insmod –f to force the loader for versions of the loader that were not compiled for the current kernel. This will produce warnings but should* load.
