How to mount your Synology NAS (or any other NAS brand) shared folder under Linux using CIFS.

CIFS stands for "Common Internet File System," also known under the older name SMB (Server Message Block),  which is a network protocol used by Windows clients for issuing file access requests to Windows servers

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

Start also Dolphin (Dolphin is the default KDE 4 file manager), or your preferred file explorer, and navigate to /mnt.

You can now drag each directory to the left bar (“Places”) for quicker access

Or you can drag them on the desktop

Choose either Folder view to view content in real time in a plasma widget, or as icon. You can see the result below:

You’re done, I did also remove Kaffeine, install VLC and I am enjoying Streaming from the Synology NAS

NOTE:

I did also add this how to to the official Synology WIKI page http://forum.synology.com/wiki/index.php/Mapping_a_Network_Drive

Citrix XenServer is a complete, managed server virtualization platform built on the powerful Xen hypervisor. Xen technology is widely acknowledged as the fastest and most secure virtualization software in the industry.

In case you don’t have any optical drive attached to the server, this small how to will help you to install Xen Server as domain 0 (dom0) using USB flash drive.

1. Download XEN server iso from http://www.citrix.com/English/ss/downloads/index.asp
2. Format your USB drive using FAT32,
3. Use an older version of UNetbootin to create a bootable disk. Download, start and follow the instruction in user interface,
4. Just plug the USB flash drive and boot on it to complete the installation of Xen Server.

UNetbootin allows you to create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions without burning a CD. It runs on Windows, Linux, and Mac OS X. You can either let UNetbootin download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list (such as Ubuntu, Fedora, openSUSE, FreeBSD, PartedMagic)

I used the version 393 and it worked, the latest version (549),  seems to have a bug and refuse to boot with an error message

mboot.c32: not a COM32R image
