To access a Microsoft Windows share from a CentOS Linux server there are a few commands that worked for this configuration: Microsoft Windows Server 2003 and CentOS 5.8. This is a quick and dirty guide assumes that a Windows share already exists and uses root. In a production environment, an alternate user would be more appropriate.

From the Linux server.

Create an empty folder.

mkdir /mnt/share

Mount the Windows share.

mount -t cifs //IP.AD.DR.ESS/share -o username=username,password=password /mnt/share

According to the comment below, UTF8 is needed in cases. I have added it here, however, haven’t personally tested – yet.

mount -t cifs //IP.AD.DR.ESS/share -o username=username,password=password,iocharset=utf8 /mnt/share

To make this a perminent mount, edit the /etc/fstab and append the following line to the end of the file.

//IP.AD.DR.ESS/share /mnt/share cifs root,uid=0,ro,suid,username=username,password=password 0 0

Re-mount the /etc/fstab without restarting the computer.

mount -a

Of course, there are many variables that can be changed. like the filesystem, user, uid, whether or not the mount will be read-only “ro” or read-write “rw”.
