- USB disk
格式化成ext2/3格式, with gparted in linux. 根据官方wiki, 最新的v24已经
不用jffs了, 目前的dd-wrt目录结构是这样的:
```
/tmp ## mounted on the RAM drive of dd-wrt
/jffs ## builti-in flash, 已经disable
/mnt ## used for rw drive
```
因此根据需要格式化, 如果你的硬盘一直要与路由连, 或者需要在硬盘上装软件
, 就格成ext3,如果只是存储数据, 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建议连路由专用的硬盘可用格式成这样
```
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
你需要用ssh或者telnet连接router来安装软件

# 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`
我的usb读卡器mount到了`/mnt/sda_part1`上, 需要再手动mount到mnt目录下
- mount some directions
```sh
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
```sh
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:
```sh
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
```sh
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, 而默认transmission会到`/tmp/`下
找, 因此需要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`
编辑确保跟如下几行一样
```json
{
"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
```sh
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`
这样就可以远程访问transmission了
