Open a terminal and as root, create as many directory as needed in /mnt/
# sudo mkdir /mnt/video
# sudo mkdir /mnt/music
Unfortunately there is no frontend or editor user interface for maintaining the entries of /etc/fstab, you’ll have to use your favorite text editor to add the following entries (one shared folder = one line)
# vi /etc/fstab
//ipadress/shareName /mnt/directory cifs iocharset=utf8,user=synologyUser,password=synologyUserPassword,rw,
uid=linuxLogonUser,gid=linuxLogonUserGroup 0 0
For example, in OpenSuSE 11.3
//nas/video /mnt/video cifs iocharset=utf8,
user=admin,password=admin,rw,uid=cedric,gid=users 0 0
