Just got a free Dell Inspiron530, with nice specification. I plan to use it us my working desktop. So, start to install xubuntu on it. As I have already have a live-usb, the usb will be used as the installation source. But I get a problem. We the system try to boot from my USB drive, it complain "boot error". This is really strange as I use to use my USB driver to install another two computer. After googling on the internet, I figure out the problem is from Dell's awful BIOS. The BIOS require USB drive to be exactly formated as it wanted, otherwise it will treat the USB drive as USB-zip0. The only software that I find be able to formate my USB drive to follow Dell's requirement is HP USB storage format tool.
After format my USB drive by using HP USB tool, this computer successfully recognized USB drive as USB-HDD and it did but into xubuntu installation interface. But I got another problem. The installation program cannot read the partition. The reason is, this old computer's hard disk used to be used to build a raid. So, there is old raid information on it. After remove the raid information by using
"dmraid -E -r /dev/sda".
xubuntu installation program successfully recognized all my existed partition.

中午在酒庄就餐
在吃喝一顿之后，我们前往第二个酒庄：lindemans
傍晚返回悉尼，路过有名的The Star （都城）
在悉尼的第三天，也是本次悉尼游的最后一天，晚餐就在市中心的回转寿司店。在这里吃到了我目前为止品尝过的最美味的寿司。还有本吃货的最爱，鳗鱼寿司。回转寿司店根据盘子的颜色不同，有不同的价钱。基本上是从2澳元到6澳元不等。吃完之后，自己的面前会有厚厚的一叠盘子。

WR1043ND to OpenWRT
Complie personal build
First, I downloaded OpenWRT from official website and flushed it, it works pretty good. But there is a very important problem. OpenWRT does not support channel 12 and 13. These two channels are not allowed to be used in US. But, I am living in EU, it is no sense to waste two channels if there are more then 10 neighbors' wireless networks around you. As OpenWRT has an agreement with Atheros, they cannot provide pre-build bin file which support channel 12 and 13. So, I have to build my own one to let OpenWRT respect user's setting. On ubuntu/debian system install:bash$ sudo apt-get install subversion build-essential libncurses5-dev zlib1g-dev gawk flex quilt git-coreCreate a folder to hold source files for compile:
bash$ mkdir ~/OpenWRT bash$ cd OpenWRT bash$ svn co svn://svn.openwrt.org/openwrt/trunk/ bash$ cd trunkThe respository can be found at https://dev.openwrt.org/wiki/GetSource. Option packages can be enabled in feeds.conf.default file which located at the root folder of the repository. Next, in order to update feeds after changing the sources, we need to run:
bash$ scripts/feeds update -a bash$ scripts/feeds install -a
Then "scrips/feeds search xxx" can be used to search package and "scripts/feeds install xxx" can be used to install packages. The dependency will automatically be resolved by feed script.
To build rom for my router. I need to specify the setting:
bash$ menuconfig
Target System: Atheros AR71xx/AR7240/AR913X
Target Profile: TP-LINK TL-WR1043ND v1
Check the setting in Kernel modules-->Wireless Drivers-->kmod-ath-->configuration
$make -j 3
First Login
After compile, file with name "openwrt-ar71xx-tl-wr1043nd-v1-squashfs-factory.bin" can be found in output folder. This is the file that need to flash on a factory router. Another one with name "openwrt-ar71xx-tl-wr1043nd-v1-squashfs-sysupgrade.bin" can be used to update router which already installed OpenWRT. The default status of a freshly instelled router is:- The internal interface lan and the wireless interface/interfaces wlan0 / wlan1 are bridged together to br-lan
- wifi is disabled
- the IP address of the internal interface/bridge of the OpenWrt-device is 192.168.1.1/24
- dnsmasq is running; it allocates IP addresses in the range of 192.168.1.100 to .250 on the internal interface to connected hosts
- dropbear does not accept connections
- telnet daemon is running on standard port (23)
telnet 192.168.1.1to connect to the router and:
root@openwrt:~$ passwd Changing password for root New password: Retype password: Password for root changed by root root@openwrt:~$after you set a password the telnet daemon will be disabled, type exit into the prompt.
without reboot, SSH is now available; so is HTTPS if the WebUI (LuCI) is installed with it's TLS-modules.
login again with ssh root@192.168.1.1
Install luci
Luci is a very easy to use GUI for OpenWRT. It can be installed from repository (other method). OpenWRT repository management system is similar to debian's dpkg, instead, it named opkg. As apt-get, the first thing to do is to retrieve the current list of available packages in the repository:opkg updateFor a full LuCi installation without HTTPS suport:
opkg install luci
Start LuCi(uHTTPd) server
Enable automatic start at boot and manually start the LuCi server with commands:/etc/init.d/uhttpd enable /etc/init.d/uhttpd startAfter this, it is able to connect the router with web browser at http://192.168.1.1
uHTTPd can be configured, but it is not required.
Install required modules for WiFi
opkg update
opkg install kmod-ath9k wpad-mini
Wifi will be ready after reboot.
Install USB/HDD
To enable mass storage capability:
root@OpenWrt:~# opkg install kmod-usb-storageAfter that we can enable file system that we want to use. For example, we want to enable ext4 support:
root@OpenWrt:~# opkg install kmod-fs-ext4Now we can use blkid to list all avaiable disk. In my case, I got:
root@OpenWrt:~# blkid /dev/sda1: UUID="0737-3F5F"Ref:

Setup DNS and DHCP
ref: http://wiki.openwrt.org/doc/uci/dhcpSetup DDNS with ddns-scripts
Web interface can be used. But, in order to save more space, I decide to go to scripts. Check: http://wiki.openwrt.org/doc/howto/ddns.clientInstall ddns-scripts package
root@OpenWrt:~# opkg install ddns-scriptsThe configuration is stored in /etc/config/ddns. At least one section has to be enabled to active ddns Enable the setting:
root@OpenWrt:~# ACTION=ifup INTERFACE=wan /sbin/hotplug-call iface
WOL
I use my android phone to send wol message to my nas server. The name of the application is "Wol Wake On Lan Wan". I have already set up WOL function on my NAS. Here, we going to focus on Wol configuration on openwrt. 1. Add forwarding setting in firewall (/etc/config/firewall):
config 'redirect'
option '_name' 'wol' #name of this redirect
option 'src' 'wan' # message from internet
option 'proto' 'udp' # wol package is udp
option 'src_dport' '9' # wol port is set to 9
option 'dest_ip' '192.168.0.2' # IP of NAS server
option 'dest_port' '9'
option 'target' 'DNAT' # I am using dynamic NAT
option 'dest' 'lan' # of cause, my NAS is in my LAN
2. The next step is to add a binding between IP address and MAC address. Following ip command should be used to ask OpenWRT to remember ARP setting unless manual change or reboot. In order to keep this setting after rebooting. We need to add it to /etc/rc.local. So it will be invoked each time the router rebooted.
ip neigh add 192.168.0.2 lladdr 1c:6f:65:b7:fe:b1 nud permanent dev br-lanThis command bind ip address 192.168.0.2 to MAC address 1c:6f:65:b7:fe:b1 and this is a permanent mapping to interface br-lan. If ip command is not installed yet. Run:
opkg update opkg install ipThis command should be run manually, if we don't want to reboot the router. After this, command arp -a can be used to verify the mapping. Now the WOW should be ready.
