[gist]flash dd-wrt and install transmission in WNR2200 router

from http://oyanglul.us

Prepaire

• USB disk 格式化成ext2/3格式, with gparted in linux. 根據官方wiki, 最新的v24已經 不用jffs了, 目前的dd-wrt目錄結構是這樣的:

/tmp ## mounted on the RAM drive of dd-wrt
/jffs  ## builti-in flash, 已經disable
/mnt ## used for rw drive

所以根據須要格式化, 若是你的硬盤一直要與路由連, 或者須要在硬盤上裝軟件 , 就格成ext3,若是隻是存儲數據, whatever, fat也可用

Use ONLY ext2/3 for partition/drives that you plan for permanent connection to your DD-WRT box, or for drives where you plan to install additional software packages onto (like optware, Samba, Torrent etc.). You can use any of the three mount points: /opt, /mnt, /jffs

Use FAT32 on data partitions if you intend to connect this drive to other systems (MAC, Windows) to copy files from/to directly. You should use the mount point: /mnt

wiki建議連路由專用的硬盤可用格式成這樣

one: for optware packages - make it 32MB - 2GB - use ext2/3 as the format
    two: for swap file - make it 16-256 MB - format it as linux swap file
    three: for data space - make it fit the rest of the disk - use ext2/3 or FAT32 as the format
    four: for jffs space - make it 32MB - 2GB - use ext2/3 as the format

• Connection 你須要用ssh或者telnet鏈接router來安裝軟件 <!-- more --> # Installation #

• mount your usb Under Services->USB: * Enable Core USB Support * Disable USB Printer Support (enable it if you need printing support) * Enable USB Storage Support * Enable Automatic Drive Mount * Set Disk Mount Point to /mnt * Click Apply Settings

• make sure mount it to /mnt 個人usb讀卡器mount到了/mnt/sda_part1上, 須要再手動mount到mnt目錄下

• mount some directions

cd /mnt
mkdir etc opt root
touch optware.enable
chmod 755 etc opt root
mkdir opt/lib
chmod 755 opt/lib
cp -a /etc/* /mnt/etc/
mount -o bind /mnt/etc /etc
mount -o bind /mnt/opt /jffs 

• install opkg and libc

wget http://downloads.openwrt.org/backfire/10.03.1/ar71xx/packages/opkg_576-2_ar71xx.ipk
ipkg install libc_0.9.30.1-43.32_ar71xx.ipk 
wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/libc_0.9.33.2-1_ar71xx.ipk
opkg install libc_0.9.33.2-1_ar71xx.ipk

• Type the following lines to create the configuration file for opkg:

cat > /etc/opkg.conf << EOF
src/gz snapshots http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages
dest root /opt
dest ram /opt/tmp
lists_dir ext /opt/tmp/var/opkg-lists
EOF 

• Make sure opkg is ok

umount /jffs
mount -o bind /mnt/root /tmp/root
mount -o bind /mnt/opt /opt
export LD_LIBRARY_PATH='/opt/lib:/opt/usr/lib:/lib:/usr/lib'
opkg update 

• now you can install transmission

opkg install transmission-daemon transmission-web

• Finally change the transmission-web PATH transmission-web 的index.html文件都在 /opt/usr/share/transmission/web/下, 而默認transmission會到/tmp/下 找, 所以須要link下 ln -s /opt/usr/share/transmission/web/ /tmp/root/.local/share/transmission/web

Configure

• start daemon first transmission-daemon -g /mnt/data/torrents/.config/transmission-daemon killall transmission-daemon

• edit setting.json vi /mnt/data/torrents/.config/transmission-daemon/settings.js 編輯確保跟以下幾行同樣

  {
     "blocklist-enabled": 1,
     "download-dir": "\/mnt\/data\/torrents",
     "download-limit": 100,
     "download-limit-enabled": 1,
     "encryption": 2,
     "max-peers-global": 35,
     "peer-port": 25000,
     "pex-enabled": 1,
     "port-forwarding-enabled": 1,
     "rpc-authentication-required": 0,
     "rpc-password": "",
     "rpc-port": 9091,
     "rpc-username": "",
     "rpc-whitelist": "192.168.1.*",
     "upload-limit": 200,
     "upload-limit-enabled": 1
     }

• Restart and rock

killall transmission-daemon
transmission-daemon -g /mnt/data/torrents/.config/transmission-daemon

and also, you can enable WAN access

iptables -I INPUT 1 -p tcp --dport 25000 -j logaccept

這樣就能夠遠程訪問transmission了
