今天为将CentOS 下mysql数据库备份至windows共享目录，挂载windows共享目录的时候总是报错，经过一翻百度之后，终于解决。
[root@www ~]# mount -t cifs -o username=domain\administrator,password=Test123 //192.168.1.10/share /databackup
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
原因：命令中关于域的格式不对，正确的是:
mount -t cifs -o domain=test.com,username=administrator,password=test123 //192.168.1.10/share /databackup
或
mount -t cifs -o username=domain/administrator,password=test123 //192.168.1.10/share /databackup
/var/log/messages内容：

原因：帐号的密码过期，将windows帐号的密码改为永不过期。
[root@www /]# mount -t cifs -o username=testuser,password=123 //192.168.214.128/npwpw /databackup
mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
Sep 26 11:04:18 www kernel: CIFS VFS: cifs_mount failed w/return code = -5
原因：/databackup已经挂载了，需要先umonut，再mount
让linux 启动自动挂载在/etc/fstab中增加
//192.168.1.100/test /media cifs defaults,username=manifold,password=manifolden 0 2
Linux下mount Window的共享文件夹
mount: unknown filesystem type "smbfs’
今天在使用FC6时，发现mount不了windows的共享盘
mount -t smbfs -o username=xxx,password=xxx //hostname/dir /mnt/tmp
mount: unknown filesystem type ’smbfs’
系统已经不能识别smbfs文件系统了
查资料说RHE5的kernel已经不再支持smbfs，而改用Common Internet File Systemcifs(cifs)取代了原有的smbfs，猜想fc6也做了这个改动，所以命令就改为:
# mount -t cifs -o username=xxx,password=xxx //hostname/dir /mnt/tmp
很顺利地mount上了
