2.5 My NSA Screen

Use the My NSA screens to manage your shares and access the files in folders to which you have access. A share is a set of user access permissions for a specific folder on a volume (gives someone access to a folder). It is equivalent to the Windows concept of a shared folder, but the access rights are independent of the folder (you configure the share and the folder separately). You can map a share to a network drive for easy and familiar file transfer for Windows users. The main My NSA screen displays the shares to which you have access.

Figure 9 My NSA

The following table describes the labels in this screen.

Table 3 My NSA

LABEL My Own Shares DESCRIPTION These are the shares that you own (and manage). The share icons are folder shaped. Click a share icon to access the shares contents. A plain share icon displays for a share on a volume on the internal hard drives. A USB symbol displays on the icon for a share on an external (USB) device. An external shares icon turns gray if the share is not currently available (because the USB device was removed for example). The administrator owns and manages the public shares. Manage It Other Shares Click this button to see and configure the management details for a share. These are other shares on the internal hard drives or external (USB) devices that you can access (but not manage).

Available Disk(s) File System

6.8 External Disks

You may connect USB storage devices that support the following file systems to the NSA. Windows File Systems: NTFS, FAT32 and FAT16. Linux File Systems: ReiserFS, EXT2, and EXT3.

6.9 RAID

This section contains theoretical background on JBOD and the RAID levels used on the NSA. Skip to the next section if you already understand RAID and know what storage system you want to use on the NSA. Redundant Array of Independent Disks (RAID) is a method of storing data on multiple disks to provide a combination of greater capacity, reliability, and/or speed. JBOD (Just a Bunch Of Disks) is not a RAID storage method but it is included in this discussion. These are some terms that you need to know in order to understand storage systems. Mirroring In a RAID system using mirroring, all data in the system is written simultaneously to two hard disks instead of one. This provides 100% data redundancy as if one disk fails the other has the duplicated data. Mirroring setups always require an even number of drives. Duplexing Like in mirroring, all data is duplicated onto two distinct physical hard drives but in addition it also duplicates the hardware that controls the two hard drives (one of the drives would be connected to one adapter and the other to a second adapter). Striping Striping is the breaking up of data and storing different data pieces on each of the drives in an array. This allows faster reading and writing as it can be done simultaneously across disks. Striping can be done at the byte level, or in blocks. Byte-level striping means that the first byte of the file is sent to the first drive, then the second to the second drive, and so on. Block-level striping means that each file is split into blocks of a certain size and those are distributed to the various drives. The size of the blocks used is also called the stripe size (or block size). Parity In mirroring 50% of the drives in the array are reserved for duplicate data. Parity is another way to allow data recovery in the event of disk failure using calculations rather than duplicating the data. If you have n pieces of data, parity computes an extra piece of data. Then+1 pieces of data are stored on n+1drives. If you lose any one of the n+1 pieces of data, you can recreate it from the n that remain, regardless of which piece is lost. Parity protection is used with striping, and the n pieces of data are typically the blocks or bytes distributed across the drives in the array. The parity information can either be stored on a separate, dedicated drive, or be mixed with the data across all the drives in the array.
In the following figures, A1, A2, A3 and so on are blocks of data from the A file. Similarly, B1, B2, B3 and C1, C2, C3 ar blocks of data from the B and C files.

7.2 Network Config Screen
Click System Setting > Network > TCP/IP in the navigation panel to open the following screen. Use this screen to have the NSA use a dynamic or static IP address, subnet mask, default gateway and DNS servers.
If you change the NSAs IP address, you need to log in again after you apply changes.
Figure 64 System Setting > Network > TCP/IP
Table 23 System Setting > Network > TCP/IP
LABEL IP Address Dynamic Select this option to have the NSA get IP address information automatically. If no IP address information is assigned, the NSA uses Auto-IP to assign itself an IP address and subnet mask. For example, you could connect the NSA directly to your computer. If the computer is also set to get an IP address automatically, the computer and the NSA will choose addresses for themselves and be able to communicate. Select this option for the NSA to use fixed TCP/IP information. You must fill in the following fields. Type an IP address in this field. Type an IP subnet mask in this field. Type a default gateway address in this field. DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. If you have the IP address(es) of the DNS server(s), enter them. Select the option to have the NSA get a DNS server address automatically. Select this option to choose a static DNS server address. Type the DNS server IP address(es) into the fields below. Type a primary DNS server IP address. DESCRIPTION
Static IP Address IP Subnet Mask Default Gateway DNS
Dynamic Static Primary DNS Server
LABEL Secondary DNS Server Jumbo Frames DESCRIPTION Type a secondary DNS server IP address. Jumbo frames improve network performance. You must have a 1 Gbps (Gigabit Ethernet) network that supports jumbo frames. Select the largest size of frame that all of your network devices (including computer Ethernet cards and switches, hubs, or routers) support.
Note: If you enable jumbo frames on the NSA in a network that does not support them, you will lose access to the NSA. If this occurs, you will have to restore the factory default configuration. Push the RESET button on the NSAs rear panel and release it after you hear a beep.
Network Diagnostic Tool Use this section to test the network connection to a particular IP address or domain name. Select an address or type it into the field. Then click Ping to have the NSA send a packet to test the network connection. If the NSA is able to ping the host, the network connection is OK. Click Apply to save your TCP/IP configurations. After you click Apply, the NSA restarts. Wait until you see the Login screen or until the NSA fully boots and then use the NDU to rediscover it. Click Reset to begin configuring this screen afresh.
This chapter discusses the application screens.

Additionally, you can use HTML editing software (not included) to create an index.html or index.htm file to define and customize how your website works and looks.
8.9.1 Accessing Web-published Shares from the Internet
You need to use a public address to access the NSAs web-published shares from the Internet. If your NSA uses a private IP address, you may need to use the public IP address of your Internet gateway and configure NAT or port forwarding on your Internet gateway and possibly firewall rules in order to let people access the NSAs web-published shares from the Internet.
8.9.2 Web Publishing Port Number
If the web-published shares use a port number other than 80 (the normal port for web traffic), users must include it after the NSAs IP address in order to access the NSAs web-published shares. For example, say you specified port 8080, the NSAs IP address is 192.168.1.23, and the name of the web-published share is FamilyPhotos. You would have to enter http:// 192.168.1.23:8080/MyWeb/FamilyPhotos/ in your browsers address bar to access the shares web page. The NSAs web configurator uses port 80. To make the web configurator more secure, you can have the web-published shares use another port number. Then you can configure one set of firewall rules and NAT or port forwarding settings on your Internet gateway specifically for allowing access to the web-published shares and another separate set of rules for accessing the NSAs web configurator. In the following example, the Internet gateways firewall is configured to allow anyone to access the NSAs web-published screens using port 8080. Web configurator access (port 80) however, is only allowed from IP address a.b.c.d.

8.10 Web Publishing Screen
Click Applications > Web Publishing to open the following screen. Use this screen to turn web publishing on or off and select shares to publish.
Figure 75 Applications > Web Publishing
Table 29 Applications > Web Publishing
LABEL Disable / Enable Web Publishing Port Number DESCRIPTION Turn on web publishing to let people access files in the published shares using a web browser, without having to log into the My NSA screens. Specify a port number for accessing the published share websites hosted on the NSA. If you enter a number other than 80, make sure you include it when telling others how to access the web-published share. For example, say you specified port 8080, the NSAs IP address is 192.168.1.23, and the name of the web-published share is FamilyPhotos. You would have to enter http://192.168.1.23:8080/MyWeb/FamilyPhotos/ in your browsers address bar to access the shares web page. This list box displays the shares that the NSA does not publish for web browser access.

15.1 Troubleshooting Overview

Troubleshooting

This chapter offers some suggestions to solve problems you might encounter. The potential problems are divided into the following categories. Power, Hardware, Connections, and LEDs NSA Login and Access Reset the NSA I Cannot Access The NSA External USB Drives Media Server Functions Download Service and Broadcatching Functions Web Publishing
15.2 Power, Hardware, Connections, and LEDs
The NSA PWR LED does not turn on (no LEDs are on).
Make sure the NSA is turned on. Make sure you are using the power adaptor or cord included with the NSA. Make sure the power adaptor or cord is connected to the NSA and plugged in to an appropriate power source. Make sure the power source is turned on. Turn the NSA off and on. If the problem continues, contact the vendor.

An HDD LED is off.

The HDD LED is off when the NSA cannot detect a hard drive in the drive bay. Replace or install a hard drive. See Installing or replacing a hard drive
Chapter 15 Troubleshooting

An HDD LED is orange.

Orange means that the NSA detected an error on the hard drive (like a bad sector for example). The NSA automatically tries to recover a bad sector, but the LED stays orange until the NSA restarts. Even if the hard drive still functions, it is recommended that you replace it since errors are a sign that the hard drive may fail soon. See Installing or replacing a hard drive

An HDD LED is red.

Red means the hard drive has failed and the NSA can no longer detect it. Replace the hard drive. See Installing or replacing a hard drive If you are using a RAID I volume, you may still be able to use the volume but you should replace the faulty drive as soon as possible.
Installing or replacing a hard drive
Do not remove or install hard drives while the NSA is turned on. The NSA must be turned off before you remove or install hard drive(s).
1 Turn the NSA off, remove the rear panel and the drive tray and make sure: there is a SATA I or SATA 3.0 Gbit/s compatible hard drive installed. the hard drive is installed correctly in the drive tray. Push the tray back into NSA drive bay until the screw hole at the top of the drive tray is flush with the drive bay (see the NSA Quick Start Guide and Section 6.6 on page 78). the hard drive could be faulty. Try a different hard drive or test the original hard drive in a different NSA or computer. 2 If you had to replace the drive, turn on the NSA and go to the Storage Setting screen. If you have a RAID I volume click the Repair icon next to the new drive. If you are using RAID 0 you will need to recreate the whole volume. All of your data is lost. If you are using a single-disk JBOD volume, you need to create a new volume on the new drive. If you are using a two-disk JBOD volume, you need to create a whole new volume on both drives.

15.3.1 Reset the NSA

If you forget your password or cannot access the web configurator, use the RESET button at the rear of the NSA. When you use the following reset procedure, the system name and admin password are returned to the factory defaults. You may need to close and re-open the NDU to discover the NSA. This is because the NSA automatically re-acquires IP address information, so its IP address may change since. If no IP address information is assigned, the NSA uses Auto-IP to assign itself an IP address and subnet mask. For example, you could connect the NSA directly to your computer. If the computer is also set to get an IP address automatically, the computer and the NSA will choose addresses for themselves and be able to communicate. 1 Press and hold the RESET button (for about two seconds) until you hear a beep, and then release it. 2 The NSA automatically restarts to complete the reset.

I forgot the password.

The default password is 1234. If you have changed the password and forgotten it, you will have to reset the NSA - see Section 15.3.1 on page 146.
The NDU cannot discover my NSA.
Confirm that the computer running the NDU has a network connection. See the section on the NSAs LAN connection for related information. The computer running the NDU can only discover NSAs in the same subnet. NSAs connected to the same switch or router as your NDU computer are usually in the same subnet unless the router is doing subnetting or the switch is implementing VLAN. The Memeo Autobackup program uses the same network port as the NDU to discover the NSA. To avoid a port conflict, do not run the Memeo Autobackup program at the same time as the NDU. Close the NDU and reopen it.
15.3.2 Enabling Scripting of Safe ActiveX Controls
If pages of the web configurator do not display properly in Internet Explorer, check that scripting of safe ActiveX controls is enabled. 1 In Internet Explorer, click Tools, Internet Options and then the Security tab.
Figure 96 Internet Options: Security

7 After the network card restart process is complete, make sure the Status is Active in the Network Configuration screen.
Using Configuration Files
Follow the steps below to edit the network configuration files and set your computer IP address. 1 Assuming that you have only one network card on the computer, locate the ifconfigeth0 configuration file (where eth0 is the name of the Ethernet card). Open the configuration file with any plain text editor. If you have a dynamic IP address, enter dhcp in the BOOTPROTO= field. The following figure shows an example.
Figure 116 Red Hat 9.0: Dynamic IP Address Setting in ifconfig-eth0
DEVICE=eth0 ONBOOT=yes BOOTPROTO=dhcp USERCTL=no PEERDNS=yes TYPE=Ethernet
If you have a static IP address, enter static in the BOOTPROTO= field. Type IPADDR= followed by the IP address (in dotted decimal notation) and type NETMASK= followed by the subnet mask. The following example shows an example where the static IP address is 192.168.1.10 and the subnet mask is 255.255.255.0.
Figure 117 Red Hat 9.0: Static IP Address Setting in ifconfig-eth0
DEVICE=eth0 ONBOOT=yes BOOTPROTO=static IPADDR=192.168.1.10 NETMASK=255.255.255.0 USERCTL=no PEERDNS=yes TYPE=Ethernet
2 If you know your DNS server IP address(es), enter the DNS server information in the resolv.conf file in the /etc directory. The following figure shows an example where two DNS server IP addresses are specified.
Figure 118 Red Hat 9.0: DNS Settings in resolv.conf
nameserver 172.23.5.1 nameserver 172.23.5.2
3 After you edit and save the configuration files, you must restart the network card. Enter./network restart in the /etc/rc.d/init.d directory. The following figure shows an example.
Figure 119 Red Hat 9.0: Restart Ethernet Card
[root@localhost init.d]# network restart Shutting down interface eth0: Shutting down loopback interface: Setting network parameters: Bringing up loopback interface: Bringing up interface eth0: [OK] [OK] [OK] [OK] [OK]
Enter ifconfig in a terminal screen to check your TCP/IP properties.

required form of the work that uses the Library must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to

0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The Program, below, refers to any such program or work, and a work based on the Program means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term modification.) Each licensee is addressed as you. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

Any Modification which You create or to which You contribute must be made available in Source Code form under the terms of this License either on the same media as an Executable version or via an accepted Electronic Distribution Mechanism to anyone to whom you made an Executable version available; and if made available via Electronic Distribution Mechanism, must remain available for at least twelve (12) months after the date it initially became available, or at least six (6) months after a subsequent version of that particular Modification has been made available to such recipients. You are responsible for ensuring that the Source Code version remains available even if the Electronic Distribution Mechanism is maintained by a third party. 3.3. Description of Modifications. You must cause all Covered Code to which You contribute to contain a file documenting the changes You made to create that Covered Code and the date of any change. You must include a prominent statement that the Modification is derived, directly or indirectly, from Original Code provided by the Initial Developer and including the name of the Initial Developer in (a) the Source Code, and (b) in any notice in an Executable version or related documentation in which You describe the origin or ownership of the Covered Code. 3.4. Intellectual Property Matters (a) Third Party Claims If Contributor has knowledge that a license under a third party's intellectual property rights is required to exercise the rights granted by such Contributor under Sections 2.1 or 2.2, Contributor must include a text file with the Source Code distribution titled LEGAL which describes the claim and the party making the claim in sufficient detail that a recipient will know whom to contact. If Contributor obtains such knowledge after the Modification is made available as described in Section 3.2, Contributor shall promptly modify the LEGAL file in all copies Contributor makes available thereafter and shall take other steps (such as notifying appropriate mailing lists or unscrupulous) reasonably calculated to inform those who received the Covered Code that new knowledge has been obtained. (b) Contributor Apes If Contributor's Modifications include an application programming interface and Contributor has knowledge of patent licenses which are reasonably necessary to implement that API, Contributor must also include this information in the legal file. (c) Representations. Contributor represents that, except as disclosed pursuant to Section 3.4 (a) above, Contributor believes that Contributor's Modifications are Contributor's original creation(s) and/or Contributor has sufficient rights to grant the rights conveyed by this License. 3.5. Required Notices. You must duplicate the notice in Exhibit A in each file of the Source Code. If it is not possible to put such notice in a particular Source Code file due to its structure, then You must include such notice in a location (such as a relevant directory) where a user would be likely to look for such a notice. If You created one or more Modification(s) You may add your name as a Contributor to the notice described in Exhibit A. You must also duplicate this License in any documentation for the Source Code where You describe recipients' rights or ownership rights relating to Covered Code. You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Code. However, You may do so only on Your own behalf, and not on behalf of the Initial Developer or any
