+Configuration of Automatic.
+\\
+I just recently decided to test out Automatic again, i had issues the last time but it seems everything works perfectly now so i'm including this here.
+\\
+SSH into your NAS via PuTTY and make sure you're in /mnt/HD/HD_a2
+<code>
+wget http://kylek.is-a-geek.org:31337/files/Automatic-0.7.1-1.tgz

+funpkg -i pcre-7.7-1.tgz
+funpkg -i Automatic-0.7.1-1.tgz
+</code>
+\\
+You then need to edit the automatic.sh located in /ffp/start.
+<code>
+cd /ffp/start/
+nano automatic.sh
+</code>
+Edit the line from
+<code>
+automatic_flags="-c /ffp/etc/automatic.conf -l /mnt/HD_a2/.transmission-daemon/automatic.log"
+</code>
+to
+<code>
+automatic_flags="-c /ffp/etc/automatic.conf -l /mnt/HD/HD_a2/.transmission-daemon/automatic.log -v 2"
+</code>
+Press Ctrl + O and Ctrl + X
+\\
+\\
+Now you need to create a automatic configuration file. We'll use the sample file.
+<code>
+cd /ffp/etc/
+nano automatic.conf-sample
+</code>
+Remove the # from rpc-host and rpc-port.
+\\
+If you need #rpc-auth means you've configured a username and password for Transmission.
+\\
+Change the line from
+<code>
+torrent-folder = "/tmp"
+</code>
+to
+<code>
+torrent-folder = "/mnt/HD/HD_a2/.transmission-daemon/autotorrents"
+</code>
+and the line from
+<code>
+statefile = "~/.config/automatic.state"
+</code>
+to
+<code>
+statefile = "/mnt/HD/HD_a2/.transmission-daemon/automatic.state"
+</code>
+Edit in your RSS Feeds and filters
+\\
+Press Ctrl + O when you're done and save it as automatic.conf
+then Press Ctrl + X
+\\
+Now we need to go create the folders and state file for automatic. Fire up PuTTY again and do these commands:
+<code>
+cd /mnt/HD/HD_a2/.transmission-daemon
+mkdir autotorrents
+touch automatic.state
+chmod 777 automatic.state
+</code>
+\\
+Now you can start automatic.sh by typing
+<code>
+/ffp/start/automatic.sh start
+</code>
+If you want to stop automatic
+<code>
+/ffp/start/automatic.sh stop
+</code>
+\\
+Just some tips for the Filters. My RSS Feeds are basically sorted out so I used this section for filters
+<code>
+filter = {  pattern => "(?!.*.)"
+         }
+</code>
+It basically means that it applies to all RSS Feeds.
+\\
+All my commands should be correct, someone edit em if they're wrong. Have fun!

+===== Building a Custom Firmware ("ROM") =====
 D-Link provides a complete build environment on its [[ftp://ftp.dlink.de/dns/dns-320/driver_software/DNS-320_GPL_code_revA.tgz|ftp server]] that lets you create your own firmware images easily. Untar it and run
 <code> source build_fw </code>
 this will result in a file "DNS320-firmware" in the merge folder, which can be flashed to the unit via the webinterface (firmware update).
-Right now the build_fw script does not do a full rebuild of the complete firmware, it rather puts together precompiled binaries that come with the built environment. [[http://forum.dsmg600.info/viewtopic.php?pid=41860#p41860|Here]] is an attempt at rebuilding the build script. [[http://curvedbrain.org/2008/06/09/building-firmware-binary-image-d-link-dns-323/|This]] blog post describes how to assemble a firmware image for the [[http://wiki.dns323.info/start|DNS-323]] and will probably helpful for the DNS-320 as well.

+This is just a quick n' dirty way to get root access to the device. This configuration is __not__ recommended as permanent.

+===== Detect USB button pressure =====
+I wanted to replace the 8 seconds pressure on the power button by a simple pressure on the usb button.
+So, i've analysed the chk_io program while it seemed to be the one which does the job for the usb copy.
+The chk_io is not gpl, so only the binary is available. I used strace and LD_PRELOAD on ioctl to analyse it,
+and finally found a similar program for the dns-323.
+I'm not sure it's required to open /dev/REG each time, but it's what the official program does.
+Idem for the open attributes.
+I've created :
+* ffp/extra/shutdown/chkbutton (gcc -static -s chkbutton.c -o chkbutton)
+* /ffp/extra/shutdown/shutdown_ffp.sh
+* /ffp/extra/shutdown/usbOff.sh
+* /ffp/etc/fun_plug.local
+Just copy these files or feel free to modify them.
+Files are available here : http://nadenislamarre.free.fr/dns320
+<code>
+# chkbutton.c
+#define _GNU_SOURCE 1
+#include <stdio.h>
+#include <stdlib.h>
+#include <fcntl.h>
+#define DEVICE "/dev/REG"
+#define REQUEST 0x65
+#define REGISTER 0x10110
+#define BTN_NOTUSB 0x08000000
+int main (int argc, char *argv[]) {
+  int fd;
+  unsigned long data[2];
+  while(1) {
+    if ((fd = open (DEVICE, O_RDWR|O_LARGEFILE)) == -1) {
+      exit(1);
+    }
+    data[0] = REGISTER;
+    data[1] = 0;
+    if(ioctl(fd, REQUEST, &data) == 0) {
+      if(! ((data[1] & BTN_NOTUSB) == BTN_NOTUSB)) {
+        printf("USB\n");
+        fflush(stdout);
+        usleep(1000 * 1000 * 3);
+      }
+    }
+    close(fd);
+    usleep(1000*30);
+  }
+  return 0;
+}

+The following script called in the /ffp/etc/fun_plug.local make the dns-320 reboot just by pressing on the usb button.
+The redirection to /dev/null is required because the shutdown.sh script kill processes on some conditions.
+<code>
+#!/bin/sh
+# /ffp/extra/shutdown/usbOff.sh
+export PATH=$PATH:/bin:/sbin
+chkbutton |
+while read BTN
+do
+  if test "$BTN" = "USB"
+  then
+    led usb blue blinking
+    shutdown_ffp.sh >/dev/null 2>/dev/null
+    exit 0
+  fi
+done
+</code>
+<code>
+#!/bin/sh
+# /ffp/etc/fun_plug.local
+# replacement for shutdown ; must not be on a mounted device
+cp /ffp/extra/shutdown/* /sbin
+usbOff.sh&
+</code>
+The shutdown script is the same as the official one except that i've added a proper shutdown for ffp : /ffp/etc/rc stop
+<code>
+#!/bin/sh
+# /ffp/extra/shutdown/shutdown_ffp.sh
+source /usr/local/modules/files/project_features
+/ffp/etc/rc stop
+kill_running_process
+#kill -9 -1
+# remove link file
+rm /usr/local/upload
+sync
+umount_dev.sh all
+umount /usr/local/config
+sleep 1
+# shutdown device
+MODEL=$(cat "/usr/local/modules/files/model")
+echo "MODEL:$MODEL"
+if [ "$PROJECT_FEATURE_MCU_CHIP_WT693P" = "1" ]; then
+	echo "device shutdown"
+	up_send_ctl DeviceShutdown 0
+elif [ "$PROJECT_FEATURE_MCU_CHIP_69P803" = "1" ]; then
+	echo "send cmd to micro-p to shutdown"
+	up_send_ctl DeviceShutdown 1
+else
+	poweroff
+fi
