默认Raspberry不自带samb，需要手动安装。
如果默认的rasp源不好用的话，可以使用下面从网上找的：
deb http://mirrors.cqu.edu.cn/Raspbian/raspbian wheezy main contrib non-free rpi deb-src http://mirrors.cqu.edu.cn/Raspbian/raspbian/ wheezy main contrib non-free rpi deb http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ wheezy main contrib non-free rpi deb-src http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ wheezy main contrib non-free rpi deb http://mirrors.neusoft.edu.cn/raspbian/raspbian/ wheezy main contrib non-free rpi deb-src http://mirrors.neusoft.edu.cn/raspbian/raspbian/ wheezy main contrib non-free rpi deb http://mirrors.ustc.edu.cn/raspbian/raspbian/ wheezy main contrib non-free rpi deb-src http://mirrors.ustc.edu.cn/raspbian/raspbian/ wheezy main contrib non-free rpi
直接install samba可能会报错，先把错误提示中版本不对的依赖项卸载掉，比如我的树莓派需要重新安装这几个：
apt-get remove samba-common apt-get remove libwbclient0
然后正常安装samba，记得不光samba服务，还有管理工具：
apt-get install samba apt-get install samba-client apt-get install samba-common apt-get install samba-common-bin
装完这些基本够用了。
修改samba配置：在/etc/samba/smb.conf中，修改以下两个键值：
browseable = yes
read only = no
