 +==== Download files ====
 +
 +Telnet into your DNS-323, and download ARMedslack packages from the slackware.pl mirror:
 +
 +  # mkdir -p /mnt/HD_a2/home/armedslack
 +  # cd /mnt/HD_a2/home/armedslack
 +  # rsync -avP inreto.de::dns323/armedslack/get-armedslack.sh .
 +  # ./get-armedslack.sh
 +
 +Get kernel and ramdisks:
 +
 +  # cd /ffp/boot
 +  # rsync -avP inreto.de::dns323/armedslack/ramdisks .
 +
 +
 +==== Installer ====
 +
 +Boot the installer ramdisk:
 +
 +  # cd /ffp/boot/ramdisks
 +  # ./installer.sh
 +
 +As usual, wait a few seconds, open a new telnet session and login as
 +root (no password required). If you cannot establish a new connection
 +within a minute or two, the loader might have failed due to memory
 +fragmentation. Reboot your box and retry.
 +
 +We install to a 'linux' directory on /dev/sda2, and set the ROOT
 +environment variable for installpkg:
 +
 +  # mount /dev/sda2 /mnt
 +  # mkdir -p /mnt/linux
 +  # export ROOT=/mnt/linux
 +
 +We're going to chroot to /mnt/linux later for the main package
 +installation. Make sure we can access the packages, then:
 +
 +  # mkdir -p /mnt/linux/old
 +  # mount /dev/sda2 /mnt/linux/old
 +
 +Some packages (e.g. sysvinit) need to know that we're installing
 +Slackware:
 +
 +  # touch /etc/slack-installer
 +
 +
 +==== Package tools ====
 +
 +We first unpack the package tools to get the installpkg utility:
 +
 +  # cd /mnt/linux
 +  # tar xzf /mnt/linux/old/home/armedslack/armedslack-current/slackware/a/pkgtools*.tgz
 +  # rm -rf install
 +
 +Next, we prepare the chroot by installing a few essential packages:
 +
 +  # cd /mnt/linux/old/home/armedslack/armedslack-current/slackware
 +  # /mnt/linux/sbin/installpkg a/*.tgz
 +
 +Ignore the warnings.
 +
 +
 +==== Chroot ====
 +
 +We can now mount the usual virtual filesystems and enter the chroot.
 +
 +  # cd /mnt/linux
 +  # mount -t proc proc proc
 +  # mount -t sysfs sysfs sys
 +  # chroot . /bin/bash -ls
 +
 +Ignore the 'cat' error.
 +
 +
 +==== ARMedslack packages ====
 +
 +Unset $ROOT now:
 +
 +  # unset ROOT
 +
 +Ready to install ARMedslack packages. First, properly reinstall
 +the a series:
 +
 +  # cd /old/home/armedslack/armedslack-current/slackware
 +  # upgradepkg --reinstall a/*.tgz
 +
 +Continue with:
 +
 +  # installpkg ap/*.tgz d/*.tgz l/*.tgz n/*.tgz tcl/*.tgz
 +
 +This takes a while and installs about 2GB.
 +
 +Finally, remove the following packages which are specific to a different
 +hardware platform:
 +
 +  # removepkg kernel-modules kernel_versatile
 +
 +
 +==== Network Configuration ====
 +
 +We start with the network config:
 +
 +  # cd
 +  # netconfig
 +
 +Next, activate the telnet or ssh server:
 +
 +For telnet, enable telnet via inetd:
 +
 +  # sed -i '/^#telnet/ s@^#@@' /etc/inetd.conf
 +  # chmod a+x /etc/rc.d/rc.inetd
 +
 +Double check with:
 +
 +  # grep telnet /etc/inetd.conf
 +  telnet  stream  tcp    nowait  root    /usr/sbin/tcpd  in.telnetd
 +
 +To activate the ssh server:
 +
 +  # chmod a+x /etc/rc.d/rc.sshd
 +
 +
 +==== root password ====
 +
 +Now, set a root password:
 +
 +  # passwd
 +
 +To allow root login over telnet/serial, change /etc/securetty:
 +
 +  # sed -i '/^#[pt]/ s/#//' /etc/securetty
 +
 +
 +
 +==== Time zone ====
 +
 +To select your timezone, run
 +
 +  # timeconfig
 +
 +
 +==== System initialization ====
 +
 +Next, we adjust the boot files. Since the DNS-323 is headless, we
 +don't need the standard virtual consoles:
 +
 +  # sed -i 's@^c@#&@' /etc/inittab
 +
 +But we want the serial console. The following sed command removes
 +the comment character from the 's1' entry:
 +
 +  # sed -i '/^#s1:/ s@#@@' /etc/inittab
 +
 +We also need to disable automatic filesystem checks at boot. We do
 +this by simply replacing /sbin/fsck with /bin/true in rc.S:
 +
 +  # sed -i 's@/sbin/fsck@/bin/true@' /etc/rc.d/rc.S
 +
 +Also, rc.S will complain if the root filesystem is mounted read-write.
 +Make it continue with:
 +
 +  # sed -i '/read junk/d' /etc/rc.d/rc.S
 +
 +
 +==== Disable unneeded services ====
 +
 +By default, ARMedslack starts a number of services that we don't
 +need on the DNS-323. To disable them, do:
 +
 +  # cd /etc/rc.d
 +  # chmod a-x rc.acpid rc.alsa rc.pcmcia rc.wireless rc.yp.new
 +  # rm rc.modules-* rc.font.new
 +
 +
 +
 +==== fstab ====
 +
 +Get the inital /etc/fstab:
 +
 +  # cd /etc
 +  # rsync -avP inreto.de::dns323/armedslack/etc/fstab .
 +
 +It looks like this:
 +
 +  # cat fstab
 +  /dev/sda1      swap            swap    defaults        0      0
 + 
 +  sysfs          /sys            sysfs  defaults        0      0
 +  proc            /proc          proc    defaults        0      0
 +  devpts          /dev/pts        devpts  mode=0620      0      0
 +  tmpfs          /dev/shm        tmpfs  defaults        0      0
 +
 +
 +
 +==== fan controller ====
 +
 +Get and unpack the fanctl source code:
 +
 +  # cd
 +  # wget http://www.inreto.de/dns323/utils/fanctl-2.tar.gz
 +  # tar xzvf fanctl-2.tar.gz
 +
 +Compile and install:
 +
 +  # cd fanctl-2
 +  # make
 +  # cp fanctl /usr/sbin
 +  # cp fan.conf /etc
 +
 +Add fanctl to /etc/rc.d/rc.local, so it's started automatically on
 +boot:
 +
 +  # echo 'fanctl /etc/fan.conf >/dev/null 2>&1 </dev/null &' >>/etc/rc.d/rc.local
 +
 +
 +
 +==== Done ====
 +
 +Finally, exit the chroot, and reboot into the firmware:
 +
 +  # exit
 +  # reboot
 +
 +Start ARMedslack with:
 +
 +  # cd /ffp/boot/ramdisks
 +  # ./linux.sh
 +
 +Because SSH keys are generated during the initial boot, it takes a few
 +minutes.
 +
 +The linux initramfs will search partitions for linux/sbin/init, and if found,
 +chroot and exec sbin/init.
