路由器 访问windows共享文件，读取相关的文件，判断文件的大小
一. ubuntu 1604测试如下
直接使用命令安装samba和smbclinet，同时安装cifs文件系统格式，即mount.cifs命令。
1. 关于Ubuntu16.04连接Windows10共享失败的问题解决
一开始以为是Windows防火墙的问题，但是关闭后故障依旧，把samba等一系列服务全部重装，问题依旧，尝试使用smbclient命令行工具连接共享，
smbclient -L 192.168.1.198 -U username%password
WARNING: The "syslog" option is deprecated
protocol negotiation failed: NT_STATUS_CONNECTION_RESET
2. 解决办法：
得到如下错误信息，后来在samba的一个国外wiki上找到了解决办法：
Protocol negotiation failed: NT_STATUS_CONNECTION_RESET
Probably the server is configured not to accept protocol SMB1. Add option client max protocol = SMB2 in /etc/samba/smb.conf. Or just pass argument -m SMB2 to smbclient.
意思是我们目前的samba客户端使用的协议是SMB1，但是Windows10已经使用SMB2这个协议了，所以我们可以使用-m SMB2这个命令行参数来强制sambaclient使用SMB2协议，但是每次都使用命令行显然不方便，那么我们可以修改配置文件，在/etc/samba/smb.conf文件中添加client max protocol = SMB2 ，重启samba服务，正常访问Windows。
注：在Windows10中最好在网络和共享中心——>高级共享设置中关闭密码保护共享，这样可以无密码的访问Windows共享，缺点是安全性下降。
3. 修改后，可以成功使用命令
- 查看远程主机的共享有那些？
[email protected]:~/work/p53/build$ smbclient -L 192.168.66.159 -U sean

3). 连接到共享后，使用的命令如下：
smb: \> ?
? allinfo altname archive backup
blocksize cancel case_sensitive cd chmod
chown close del dir du
echo exit get getfacl geteas
hardlink help history iosize lcd
link lock lowercase ls l
mask md mget mkdir more

如果想判断共享目录中某个文件的大小或者其他属性，或者读取某个文件的内容，只能下载到本地（路由器），进行访问。此方法初步判断比较笨拙。
4. 方案二
采用另外一种挂载分区的方法，要简单的多。只是需要支持cifs文件系统格式即可。
[email protected]:~/work/p53/build$ sudo mount -t cifs -o username=sean,password=sean //192.168.66.159/xsmk /mnt/winshare/
[email protected]:~/work/p53/build$
[email protected]:~/work/p53/build$
[email protected]:~/work/p53/build$ ls -l /mnt/winshare/
total 36735
-rwxr-xr-x 1 root root 11876640 Jun 27 2017 1
-rwxr-xr-x 1 root root 2586 Nov 16 13:01 10005.log

-rwxr-xr-x 1 root root 352 Jan 1 1970 test.sh
[email protected]:~/work/p53/build$
评述：此方法，简单易懂，方便操作。
二. 路由器调试
1. 内核支持 cifs 文件系统格式
进入linux目录，使用make menuconfig，进入config配置界面，打开如下功能：
File systems --->
[*] Network File Systems --->
<M> CIFS support (advanced network filesystem, SMBFS successor)
2. 编译完成，进入系统，挂载目录
~ # mount -t cifs -o username=sean,password=sean //192.168.0.157/xsmk /mnt/winss
hare/
~ # ls /mnt/winsshare/

使用以上命令挂载时，共享目录下文件太多，有可能出现以下提示信息：
~ # mount -t cifs -o username=sean,password=sean //192.168.0.157/xsmk /mnt/winss
hare/
[ 4799.310000] CIFS VFS: default security mechanism requested. The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel release 3.3
本人测试时，共享文件3376个，就会出现以上的问题。删除一些后（600个文件），可以正常挂载，没有报错。也可以正常访问。
3. 测试其稳定性
使用如下测试脚本，进行长时间测试。
~ # cat /mnt/winsshare/test.sh
#!/bin/sh
while [ 1 ]
do
filename=$(date +%s)
echo "$(date)" > $filename.log
echo "------------------------------------------------------------" >> $filename.log
echo "$(cat /proc/meminfo)" >> $filename.log
echo "------------------------------------------------------------" >> $filename.log
echo "$(top -n 1)" >> $filename.log
sleep 10
done
~ #
测试24h，系统运行正常。不过查看可用内存，会一直减小到10M左右（开始测试前为28M左右）。此问题应该是cached的问题。
三. 路由器使用smbclient的方式
首先需要移植samba到路由器源码中，进行编译。
官网地址：https://www.samba.org/samba/download/
下载： git clone https://github.com/samba-team/samba.git
1. 使用smbclient命令，查看共享
~ #
~ # smbclient -L 192.168.0.157/xsmk -U sean
params.c:OpenConfFile() - Unable to open configuration file "/lib/smb.conf":
No such file or directory
smbclient: Can't load /lib/smb.conf - run testparm to debug it
Enter sean's password:

基于以上的报错信息，可能是我们编译时，配置文件和data文件加载的目录指定问题。
2. 连接共享目录
