Note: If you change your BuffaloNAS.com name after WebAccess has been configured, WebAccess may no longer work properly. If this happens, disable and then re-enable WebAccess.

Read Only

FTP

By default, the LinkStation’s shares are only accessible by users connected to the same network or routers as the LinkStation. The optional FTP server allows users outside the local network to access the LinkStation.

Note: FTP is intended for users who already have FTP client software and have experience with it.

1 In Advanced Settings, navigate to File Sharing - Folder Setup. Move the FTP switch to the position to

enable FTP.

2 Click to the right of “Folder Setup”.

3 Choose a folder to enable remote FTP access on.

4 Select read-only or read & write for the shared folder’s attribute, check “FTP” under “LAN Protocol Support”, then

click OK.

Accessing the LinkStation with an FTP client

• To access the LinkStation via FTP, configure your FTP client software with the following settings: Hostname: IP address of the LinkStation Username: The LinkStation’s username Password: The LinkStation’s password Port: 21

• Shared folders connected by FTP are available from the “/mnt” directory. The default locations are: For RAID 0 or RAID 1: /mnt/array1/share /mnt/usbdisk1 /mnt/usbdisk2 For JBOD: /mnt/disk1/share /mnt/disk2/share2 /mnt/disk3/share3 /mnt/disk4/share4 /mnt/usbdisk1 /mnt/usbdisk2

Accessing the LinkStation with Anonymous User:

• To allow anonymous access to your FTP share, disable access restrictions.

• To access the LinkStation via anonymous FTP, configure your FTP client software with the following settings: Hostname: IP address of the LinkStation Username: Anonymous Password: Any character string

Port: 21

Notes:

• Keep your LinkStation’s firmware up-to-date.

• Don’t use FTP to share files and folders with multi-byte characters in their names with a Mac. Use an AFP or SMB connection instead.

• If a file was created or copied by AFP, you may not be able to delete it using an FTP connection. If this occurs, use an SMB or AFP connection instead to delete the file.

• For FTP connections, make sure that the total filename including directory path is 250 single-byte characters or less.

Chapter 4 Access Restrictions

You may restrict access to specific shared folders.

Notes:

• Access restrictions can be set separately for each shared folder, but not for folders within the shared folders.

• Configure access restrictions through Settings. Configuring access restrictions through Windows is not supported and may cause unexpected behavior.

• Depending on your settings, access restrictions may not affect users who are accessing via WebAccess, Backup, or DLNA.

Configuring Access Restrictions on Users and Groups

Adding a Shared Folder

1 In Advanced Settings, navigate to File Sharing - Folder Setup and click the icon.

2 Click Create Folder.

3 Configure the settings, then click OK.

Notes:

• Names may contain up to 27 alphanumeric characters, hyphens (-), and underscores (_). Do not use a symbol as the first character in a name.

• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do not use a symbol or space as the first character.

• You may create up to 400 shared folders.

• The names of shared folders should not use characters from more than one language. For example, mixing Japanese and Korean characters in names is not supported.

• If multi-byte characters are used in shared folder names, configure the client language to match the characters in Management - Name/Time/Language.

Recycle Bin

To protect your data from accidental deletion, you can enable a recycle bin instead of deleting files immediately. The recycle bin will only work with SMB connections.

Accounts

Your LinkStation’s username and password should be the same as your Windows username and password. If they are different, you may not be able to access folders on the LinkStation with access restrictions configured.

Read-only Shares

By default, new shares are set with read & write access, but you may change the attribute to “Read-only” in “Shared Folder Attributes”. Read-only shares and HFS+ formatted USB hard drives will have “Read-only” added to the shared folder description.

Hidden Shares

To hide a shared SMB folder, select “Hidden Share (SMB Only)” and click OK. Folders with AFP or FTP support enabled can’t be hidden. To open a hidden folder, click Start - Search programs and files and enter “\\LinkStation’s name\Shared folder names$\” for the name. Example: If the LinkStation’s name and shared folder name is “LSXXX001” and “share”, you should enter “\\LSXXX001\share$\” in the search box.

Notes

• The following characters are handled differently by Mac OS and Windows. Avoid using these characters when sharing data between Mac OS and Windows:

• Windows does not support some characters that Mac OS and the LinkStation allow. If you create a filename on a Mac with any of the following characters, it will not display correctly on a Windows computer and you may have to connect to the LinkStation via AFP in order to display or copy any of the following characters on a Mac computer.

? [ ] / \ = + < > ; : “ , | *

• Do not use any of the following words as a username or group name: root, bin, daemon, sys, adm, tty, disk, lp, sync, shutdown, halt, operator, nobody, mail, news, uucp, ftp, kmem, utmp, shadow, users, nogroup, all, none, hdusers, admin, guest, man, www, sshd, administrator, ftpuser, apache, mysql

• Do not use any of the following words as the name of a shared folder. These words are reserved for internal use by the LinkStation: info, spool, lost+found, global, printers, homes, lp, authtest, ram, msdfs_root, mt-daapd, usbdisk# (where # is a number, for example: usbdisk1)

• Don’t use the following unsupported characters in shared folder names, workgroup names, or filenames:

• File and folder names may contain up to 255 single-byte characters.

• Configure hidden and read-only file attributes in Settings. Configuring them from within Windows is not supported and may cause unexpected behavior.

• Folder and workgroup names whose names contain non-Roman characters may not be displayed correctly.

• If shared folders are accessed from a Macintosh, information files for the Macintosh may be generated automatically. Do not delete these files. If they are deleted using Windows, this may prevent further access from a Macintosh.

• If an SMB connection is used with OS X 10.3.9, the names of mounted volumes may appear as unreadable characters

in Finder and other applications. This is not a problem with the filename or data.

• The LinkStation belongs to the default zone in AppleShareServer; the zone cannot be specified.

• When files are copied to the LinkStation or to a USB drive connected to the LinkStation, file information such as date created, date modified, and other date information may be updated or changed.

• Hard drive capacity is shown in Settings in actual gigabytes. The Properties window of Windows may show GiB instead, which will be a smaller number.

• During a file transfer, if settings are changed, the file transfer operation may be aborted.

• File copying to the LinkStation is protected by a journaling file system.

- The preset data (LinkStation name, user, and group) may be erased.

- An incomplete file may be copied and the file can no longer be deleted. If this happens, restart the LinkStation, delete the file, and perform the copy operation again.

• After a drive is formatted, the “% Used” and “Amount Used” in Settings will not be 0. This is because some drive space is used for the system area.

Adding Users

1 In “File Sharing”, click the icon to the right of “Users”.

2 Click Create User.

3 Enter the desired settings, then click OK.

Notes:

• Username may contain up to 20 characters, including hyphens (-), underscores (_), periods (.), !, #, &, @, $, *, ^, and %. Do not use a symbol as the first character.

• For Windows 8, use a local username instead of your Windows Live ID.

• The user ID should be a number from 1000 to 1999. Each user ID should be unique. If this field is left blank, a user ID is assigned automatically.

• When you log in to Settings as a registered user, you can see the LinkStation’s name, IP address, workgroup, and disk status, and modify the password.

• Do not duplicate user IDs, group IDs, usernames, or group names. Each should be distinct and unique.

• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do not use a symbol or space as the first character.

• When setting users with access privileges, a maximum of 300 users, including “admin” and “guest”, can be registered in the LinkStation.

• The password may contain up to 20 alphanumeric characters and the following characters: - _ @ ! # $ % & ‘ ( ) * + , . / ; < > = ? “ [ ] ^ { } | ~. Do not use a symbol other than an underscore (_) as the first character.

• Use the same username and password for both Windows and the LinkStation or you may not be able to access shared folders.

• If a user belongs to multiple groups, the most strict access restrictions will apply. For example, if a user is added to a group with read and write access, and also to a read-only group, the user will effectively have read-only access.

Shared Folder Owners

To confirm the owner of a shared folder from Windows XP, from the Properties screen of the file or folder, open a new windows from the Security tab. Click Advanced, then click the Owner tab.

Adding Groups

1 In “File Sharing”, click the icon to the right of “Groups”.

2 Click Add Group.

3 Enter settings, then click OK.

Notes:

• Group names may contain up to 20 alphanumeric characters, hyphens (-), underscores (_), and periods (.). Do not use a symbol other than an under score (_) as the first character.

• Group descriptions may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do not use a symbol or space as the first character.

• If the group ID field is left blank, a group ID is automatically assigned. Use numbers between 1000 and 1999 to set a group ID manually. Don’t use duplicate group IDs.

• You may register up to 300 groups with the LinkStation.

• If you are logged in as a member of the “General Users” group, you can only change your own password. If you’re logged in as an “Administrator”, you can change any settings, including other user’s passwords. If you are logged in as a member of the power users group, you can create and edit shared folders, users, and groups.

Access Restrictions

1 In “File Sharing”, click the icon to the right of “Folder Setup”.

2 Click the shared folder that you want to set access restrictions for.

3 Click Edit.

4 Enable “Access Restrictions”.

5 Select the level of access for the user or group you added.

: Read and write access allowed : Read access allowed : Access prohibited

Note: An example of access restrictions by local users is shown in the screen. To apply access restrictions by group, click the Local Groups tab and select group permissions.

6 Click OK.

Notes:

• If you log in from a Microsoft network domain, you can set access restrictions with users and groups from the domain.

• If both “Read only” and “Read & Write” permissions are given to a user, the user will have read-only access. The

most restrictive access restrictions always apply.

Active Directory

The LinkStation can join an Active Directory domain. Up to 1000 domain users and 1000 groups may be downloaded from Active Directory.

Note: If usernames or group names from Active Directory include multi-byte characters, you will not be able to configure access restrictions for them.

1 In Settings, select Network.

2 Click to the right of “Workgroup/Domain”.

3 Click Edit.

4 Select “Active Directory”, then click Next.

5 Click Yes.

6 Enter the desired settings, then click OK.

7 Choose Folder Setup.

8 Click a shared folder that you want to set access restrictions for.

9 Click Edit.

10 Enable “Access Restrictions”.

11 Select the level of access for the user or group:

: Read and write access allowed : Read access allowed : Access prohibited

12 Click OK.

Notes:

• If both read-only and read & write permissions are given to a user, the user will have read-only access. The most restrictive attribute will apply.

• To have the LinkStation join an Active Directory domain, configure it to use a DNS server that can resolve names for the Active Directory domain.

• After building an Active Directory domain, the administrator password for joining the domain must be changed at least once, or joining the Active Directory domain will fail.

• The DNS name and NetBIOS name of Active Directory domain should be identical.

• If there are more than 5 minutes difference between the LinkStation’s clock and the domain controller’s clock, joining the domain or authenticating domain users and groups may fail. For best results, use an NTP server to set the time for all network devices.

NT Domains

In an NT domain environment, the LinkStation uses account information from the NT domain server to set access restrictions for files and folders on the LinkStation. There’s no need to perform individual account management for the LinkStation. If multiple LinkStations are installed on the network, the account information is centrally managed in the NT domain, greatly reducing the operations required for installation and management.

Note: A maximum of 1000 domain users and 1000 groups can be downloaded from an NT domain server.

1 Create an account on the domain controller for the LinkStation.

2 In Settings, click Network.

3 Select Workgroup/Domain.

4 Click Edit.

5 Select “NT Domain”, then click Next.

Note: To use Active Directory from Windows 2000 or Windows Server 2003, select Active Directory instead of NT Domain.

6 Click Yes.

7 Enter settings and click OK.

Notes:

• If you change the LinkStation’s name, you will no longer be able to use domain users and groups or access restrictions. To repair this, rejoin the domain.

• If the LinkStation has joined a domain network, you cannot connect to the LinkStation via FTP.

8 Click to the right of “Folder Setup”.

9 Click a shared folder for which you want to set access restrictions.

10 Click Edit.

11 Enable “Access Restrictions”.

12 Select the level of access for “Domain Users” or “Domain Groups” you added.

: Read and write access allowed : Read access allowed : Access prohibited

13 Click OK.

Notes:

• If both read-only and read & write permissions are given to a user, the user will have read-only access. The most restrictive attribute will apply.

• If domain username is more than 20 bytes long, the LinkStation truncates it to 20 bytes.

• The LinkStation supports a domain environment with a maximum of 1000 users and 1000 groups. 10,000 users and 10,000 groups can be downloaded from the domain controller but are not supported.

• To use the LinkStation as a member server in an NT or Active Directory domain, the LinkStation should be logged in to the domain and accessed from a computer that is not a member of the domain with a valid domain account.

• If the LinkStation is a member server of an NT or Active Directory domain, you cannot connect as a guest user via AFP.

• When you change the user or group settings on the domain controller, these changes may not take effect immediately on the LinkStation until it is rebooted.

• If your LinkStation is a member server in an NT or Active Directory domain and you change the authentication method to “Workgroup”, the account on the domain controller will not be deleted automatically.

• If the LinkStation has joined a domain network, you cannot connect to it via FTP.

Delegating Authority to an External SMB Server

LinkStation on your network can be linked to an authentication server for centralized management of user accounts and passwords. The authentication server should be a TeraStation or another LinkStation.

Notes:

• Other external SMB authentication servers are not supported. Use a TeraStation or a LinkStation for the authentication server.

• For Windows 8, access by users and groups linked from the external authentication server will not be restricted.

• When saving changes to the external authentication server settings, clicking “Yes” will convert all local users to external authentication users. If external authentication is disabled, local user passwords will need to be reconfigured.

1 In Advanced Settings, navigate to File Sharing - SMB and click the icon.

2 Click Edit.

3 Enable “SMB2 Protocol”, then click OK twice.

4 In Settings, click Network.

5 Choose Workgroup/Domain.

6 Click Edit.

7 Select “Workgroup”.

8 Click Next.

9 Enter a workgroup name. Select “Assign authorization to external SMB server” and enter the authentication server’s

IP address (recommended) or name. Check “Automatic user registration” and “Use shared folder for authorization testing”. Enter the name for authorization testing and click OK.

10 A shared folder for authentication has been created on the LinkStation. Users registered to the specified

authentication server are automatically registered as users on the LinkStation when they open the shared folder for authentication. You can also register users directly.

Note: Using external authentication may require the default security settings in Windows to be changed. An easy way to do this is to run the File Sharing Security Level Change Tool, available from www.buffalotech.com. This simple tool will let you change or restore your Windows security settings to work with external authentication.

11 Choose Folder Setup.

12 Choose a shared folder to set access restrictions on.

13 Click Edit.

14 Enable “Access Restrictions”.

15 Select the level of access:

: Read and write access allowed : Read access allowed : Access prohibited

16 Click OK.

Notes:

• If both read-only and read & write permissions are given to a user, the user will have read-only access. The most restrictive attribute will apply.

• If access restrictions are set for users and groups registered in the authentication server, guest or anonymous connection is not possible with AFP or FTP connections.

• Users who are automatically registered belong to the “power users” group. They can be added to other groups from within group settings.

• Access can be restricted to specific shared folders based on username.

• The names of registered users are listed in “Users” - “External Users”. Deleting a server name may cause problems with authentication.

• When connecting through AFP or FTP, always use an IP address. Using a server name may cause problems with authentication.

• To specify a server from another subnet, enter its IP address.

• AFP and FTP connections do not support delegating authority to an external SMB server.

• Use AFP to access access-limited shared folders from OS X 10.7 instead of SMB. Enable “AFP” under “LAN Protocol Support” for the destination folders to use AFP.

Chapter 5 Managing Storage

RAID Arrays

The default RAID mode is RAID 0.

Notes:

• If you change the RAID mode, all data on the array is deleted. This is true for every procedure in this chapter. Always back up any important data before performing actions that affect your RAID.

• After the RAID mode is changed (except when creating a RAID 0 array or JBOD), the LinkStation performs a RAID check that will take about 10 hours per TB. File transfers are slower during this period. While the message “RAID I17 ARRAYx Resyncing” is displayed on NAS Navigator2, do not turn off the LinkStation. If you do, the RAID check starts over.

RAID 1

Combines 2 drives into a mirrored array. The available space in the array is the capacity of a single drive. Identical data is written to each drive. If a drive is damaged, data can be recovered by replacing the damaged drive. As long as one drive in the array remains undamaged, all data in the array can be recovered.

RAID 0

Combines 2 or more hard drives into a single array. The usable disk space is the total space of all drives used. This simple RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all data in the array is lost.

JBOD

This mode uses the hard drives inside the LinkStation as individual drives. The disk space you can use is the total capacity of all drives in the LinkStation. If any drive is damaged, then the data on that drive is lost.

Using JBOD

With JBOD, each hard drive in the LinkStation is addressed separately. To put drives from an array into JBOD mode, follow the steps below.

1 Click Drives in Advanced Settings.

2 Select RAID.

3 Select the array to delete.

4 Click Delete RAID Array.

5 Step through the wizard to delete the array.

Once JBOD mode is configured, create shared folders on each drive to use them.

Changing RAID Mode

To change the RAID mode, first put the drives in JBOD mode.

1 Click Drives in Advanced Settings.

2 Select RAID.

3 Click the array to delete.

Note: If the “RAID Mode” is blank, the array is already in JBOD mode. Proceed to step 7.

4 Click Delete RAID Array.

5 The “Confirm Operation” screen will open. Enter the displayed number, then click OK.

6 Click OK.

7 Choose the array to configure.

8 Select a RAID mode and the drives to be used, then click Create RAID Array.

9 Step through the wizard to create the array.

Note: After changing the RAID mode, create a shared folder.

RMM (RAID Mode Manager)

With RMM, you can create or expand a RAID array without erasing the data on the drives.

1 Click Drives in Advanced Settings.

2 Select RAID.

3 Choose a RAID array.

4 Check “Add a disk to RAID array with RMM. Your data will be preserved.”.

5 Select the drive whose data will be saved from the drop-down menu.

6 Check the drive to add to the RAID array.

7 Click Create RAID Array. The “Confirm Operation” screen will open.

8 Enter the confirmation number, then click OK.

RAID Scanning

RAID maintenance scans your RAID array for bad sectors and if it finds any it automatically repairs them. For best results, run RAID maintenance regularly.

1 In Advanced Settings, click Drives.

2 Move the RAID Scanning switch to the position to enable RAID Scanning.

3 Click the icon to the right of “RAID Scanning”.

4 Click Edit.

5 Select the schedule for running RAID maintenance, then click OK.

Notes:

• Check “Immediately” to run RAID maintenance immediately.

• To stop a RAID scan, click Abort RAID Scan.

Adding an External Hard Drive

Connect an External Drive

Your LinkStation includes a USB port. You can connect an external drive to this port. It will appear as a shared folder on the LinkStation. Formatted drives are detected automatically. Unformatted drives should be formatted in Settings.

After a USB drive is recognized, Windows adds “usbdisk X” under the LinkStation in “Network”, where “X” is the USB port where the hard drive is connected.

Notes:

• Hubs are not supported. Connect a single USB drive to the USB port.

• Backup data from Mac OS may include characters that cannot be written to FAT16 or FAT32 drives such as “.DS_ Store”. For best results, reformat the drive before using it as a backup target.

• You can use the USB Device Server to connect a USB hub and up to 15 USB devices. However, with USB Device Server, the USB devices cannot be used for creating shared folders or act as LinkStation backup destinations.

Formatting External Drives

Formatted drives are detected automatically. If a drive is not formatted, format it from Settings. Refer to “Formatting Drives” for the procedure.

Notes:

• Do not turn off or disconnect power to the LinkStation while formatting a hard drive.

• A format may take anywhere from a few minutes to several hours depending on the size of your drives.

• The following format types are supported: FAT32 (recommended for connecting to computers), EXT3 (recommended for sharing with other LinkStations), XFS (recommended for adding additional external storage to a LinkStation), NTFS, and HFS+ (read-only, cannot format from Settings).

Access Restrictions on External Drives

You can set access restrictions on new drives. Refer to “Configuring Access Restrictions” for details.

Note: Even if a shared folder is not visible, you can still format the drive, run a disk check, and back up the new drive.

Compatible Information

The following devices are supported by the LinkStation

• USB storage devices

• Card readers (except for card readers that can recognize two or more memory cards)

• Digital cameras

• USB-connected UPSs

• USB printers

Buffalo external USB drives are recommended.

These devices are not supported.

• DUB and DIU series drives

• Hubs, mice, and keyboards

Connect only one device to the LinkStation’s USB port. Some external drives with automatic power-on don’t turn on automatically when connected to the LinkStation. Use their manual switch to turn them on. Be sure to connect only one bus-powered drive at a time. If there is insufficient bus power for your USB drive, connect its AC adapter. Note that only the first partition of a connected USB hard drive is mounted. Additional partitions are not recognized.

Dismounting Hard Drives

If the LinkStation is powered on, dismount external drives before unplugging them. You may dismount external drives with the function button, or any drives from Settings. If the LinkStation is off, then all drives are already dismounted and may be unplugged safely.

Notes:

• Do not dismount or disconnect an external drive while any drive is being formatted, accessed, or checked for errors, or while a RAID array is being created or deleted.

• If you unplug your external drives without dismounting them, Settings may still show “usbdisk” in File Sharing - Folder Setup. Reboot your LinkStation to clear it.

Dismounting with the Function Button

If the LinkStation is on, hold down the function button for 3 seconds. The white LED will go out as all attached USB drives are dismounted. You may now unplug them safely.

Note: Dismounting drives will also restart the services for FTP, AFP, SMB, the print server, BitTorrent, WebAccess, DLNA, and the iTunes server. Don’t do this while files are being copied for accessed.

Dismounting from Settings

1 In Advanced Settings, click Drives.

2 Click the icon to the right of “USB Drives”.

3 Select the drive to dismount and click Dismount Disk. The “Confirm Operation” screen will open. Enter the displayed

number, then click OK.

4 Unplug the USB device, then click OK when the following message is displayed.

Checking Drives

A disk check tests the data on a drive in the LinkStation or connected via USB for integrity. Errors are fixed automatically. With large drives, a disk check may run for many hours. Shared folders cannot be accessed during a disk check. Do not turn off the LinkStation until the disk check is finished. Use the procedure below to run a disk check.

1 In Advanced Settings, click Drives.

2 Select Drives to check an internal drive or USB Drives to check an external drive.

3 Select the drives to test, then click Check Disk.

4 Click Check. You have the option of deleting information files from Mac OS during the check if desired.

Formatting Drives

Note: Under some circumstances, data deleted when a drive is formatted can be recovered. To ensure that data is “gone forever”, a format might not be sufficient. See “Erase Data on the LinkStation Completely”.

1 In Advanced Settings, click Drives.

2 Select Drives to format an internal drive or USB Drives to format an external drives.

3 Select the drive to format, then click Format Disk.

4 Select a format type, then click Format.

5 The “Confirm Operation” screen will open. Enter the displayed number, then click OK.

6 Depending on the size of your drive, the format may take several minutes to several hours to complete. The

power LED will flash during the format. Shared folders cannot be accessed during a format. Do not turn off the LinkStation until the disk format is finished.

Erase Data on the LinkStation Completely

Under some circumstances, data from formatted drives can be recovered. The disk erasure process in this section does a much more thorough job of erasing data. This procedure is recommended for removing all data from a drive in a way that makes it nearly impossible to recover with current tools. All data on the drives is completely erased. The LinkStation will then be in the following state:

• All drives in JBOD mode

• An empty shared folder on each erased drive

• All settings returned to their default values

• All logs deleted

Hard Drive Replacement

If a drive fails, NAS Navigator2 and Settings will show a error message.

Notes:

• Do not unplug a drive if NAS Navigator2 or Settings doesn’t show an error message. Dismount it first or shut down the LinkStation before swapping a working drive. If you remove the drive without properly dismounting it, data may be lost or the LinkStation may malfunction.

• The replacement drive should be a OP-HD/LS series drive, available from Buffalo. Using a different drive might cause your LinkStation to malfunction.

• Use a Buffalo OP-HD/LS series drive of the same size or larger for the replacement drive. If a larger drive is used, the extra space will not be usable in a mirrored RAID array.

• To avoid damaging the LinkStation with static electricity, ground yourself by touching something made of metal before handling any sensitive electronic parts.

• After a drive is replaced, it takes about 30 minutes before normal file reading and writing are restored. Settings may not be accessible during this period.

• Do not change the order of the hard drives in the LinkStation. For example, pulling out drive 1 and replacing it with drive 2 may cause data to be corrupted or lost.

• If a new drive is not recognized after installing it, click Rediscover Disk in Settings.

Hard Drive Replacement Examples
