果想要给威联通安装一个 qpkg 的安装包时，最直观界面方式就是在 App Center 中，右上角，将本地的 .qpkg 文件上传到 NAS 并安装。
但是这种方式在外网图形界面加载很慢的情况下是非常难用的，那么这个时候如果能使用命令行安装就非常方便。需要在系统中预先开启 SSH 连接，当然这一步早就做好了。然后使用 ssh 连接登录上。比如下面以安装 Entware 为例：
wget http://bin.entware.net/other/Entware_1.00std.qpkg
sh Entware_1.00std.qpkg
经过这两个步骤就 OK 了。使用 opkg 命令可能需要重新登录 NAS SSH。
其他版本的 Entware 可以从这里 获取。
关于什么是 Entware ，可以查看该 wiki，一句话概括 Entware 是一个适用于嵌入式系统的软件包库，使用 opkg 包管理系统进行管理。
软件包列表：
armv5: http://pkg.entware.net/binaries/armv5/Packages.html
armv7: http://pkg.entware.net/binaries/armv7/Packages.html
mipsel: http://pkg.entware.net/binaries/mipsel/Packages.html
x86-32: http://pkg.entware.net/binaries/x86-32/Packages.html
x86-64: http://pkg.entware.net/binaries/x86-64/Packages.html
需要注意的是安装 Entware 之后很多命令都存放在 /opt/bin 目录下，需要修改 /root 目录下的 .bashrc 文件中的 PATH 来使这些命令被命令行所见。
export PATH=/opt/bin:$PATH
