问题：
[/]# mount_smbfs //user@192.168.0.2/snapshot /mnt/
mount_smbfs: can't get server address: syserr = Host is down
[/]# mount_smbfs -I 192.168.0.2 //user@192.168.0.2/snapshot /mnt/
Password:
mount_smbfs: unable to open connection: syserr = Connection reset by peer
解决：加 -I 参数，并且使用NetBIOS名称
[/]# mount_smbfs -I 192.168.0.2 //user@NetBIOSName/snapshot /mnt/
Password:
[/]# ls /mnt/
