Mount remote windows shares under Linux

Source
All files accessible in a Linux (and UNIX) system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree.
Use the mount command to mount remote windows partition or windows share under Linux as follows:
Procedure to mount remote windows partition (NAS share)
1) Make sure you have following information:
== Windows username and password to access share name
== Sharename (such as //server/share) or IP address
== root level access on Linux
2) Login to Linux as a root user (or use su command)
3) Create the required mount point:
# mkdir -p /mnt/ntserver
4) Use the mount command as follows:
# mount -t cifs //ntserver/download -o username=vivek,password=myPassword /mnt/ntserver
Use following command if you are using Old version such as RHEL <=4 or Debian <= 3:
# mount -t smbfs -o username=vivek,password=D1W4x9sw //ntserver/download /mnt/ntserver
5) Access Windows 2003/2000/NT share using cd and ls command:
# cd /mnt/ntserver; ls -l
Where,
  • -t smbfs : File system type to be mount (outdated, use cifs)
  • -t cifs : File system type to be mount
  • -o : are options passed to mount command, in this example I had passed two options. First argument is password (vivek) and second argument is password to connect remote windows box
  • //ntserver/download : Windows 2000/NT share name
  • /mnt/ntserver Linux mount point (to access share after mounting)

man mount.cifs - mount using the Common Internet File System
mount.cifs — mount using the Common Internet File System (CIFS)
Synopsis

mount.cifs {service} {mount-point} [-o options]
DESCRIPTION
This tool is part of the samba(7) suite.
mount.cifs mounts a Linux CIFS filesystem. It is usually invoked indirectly by the mount(8) command when using the "-t cifs" option. This command only works in Linux, and the kernel must support the cifs filesystem. The CIFS protocol is the successor to the SMB protocol and is supported by most Windows servers and many other commercial servers and Network Attached Storage appliances as well as by the popular Open Source server Samba.
The mount.cifs utility attaches the UNC name (exported network resource) specified as service (using //server/share syntax, where "server" is the server name or IP address and "share" is the name of the share) to the local directory mount-point.
Options to mount.cifs are specified as a comma-separated list of key=value pairs. It is possible to send options other than those listed here, assuming that the cifs filesystem kernel module (cifs.ko) supports them. Unrecognized cifs mount options passed to the cifs vfs kernel code will be logged to the kernel log.
mount.cifs causes the cifs vfs to launch a thread named cifsd. After mounting it keeps running until the mounted resource is unmounted (usually via the umount utility).
mount.cifs -V command displays the version of cifs mount helper.
modinfo cifs command displays the version of cifs module.
