The ReadyNAS systems support both RAID levels. RAID 5 is an industry-standard RAID level whereas X-RAID is an Infrant patented RAID technology that simplifies and automates the RAID management process. X-RAID utilizes a one-volume technology with built-in volume expansion support, either by adding more disks or by replacing existing disk with larger capacity disks. For instance, you can start out with one disk, and add up to 3 more disks when you need more capacity or when you can afford them. Volume management is automatic. Add a 2nd disk, it becomes a mirror to the first, providing protection from a disk failure; add a 3rd, the capacity doubles; add a 4th, and your capacity triples – the expansion occurring while maintaining redundancy.
X-RAID also provides further expansion capability. At a future point in time, each disk can be replaced one by one, have it finish rebuilding, and after the last disk is replaced, your volume automatically expands utilizing the new capacity. This future-proof technology allows you to continuously expand as higher-capacity disks become available. Performance-wise, X-RAID is optimized for larger sequential access request pattern, such as video streaming and editing. Performance over RAID 5 in large data transfer can be as much as 15-20% better. |
 |
|
Where X-RAID excels at large sequential transfers, RAID 5 performs better in smaller random access request pattern, fitting better in most office environments. Full volume management is available when you select RAID 5 (or Flex-RAID) mode. You can delete the existing volume and recreate one or more volumes, with each volume with different snapshot space and quota specification. You also have the flexibility of assigning an unused disk as a hot spare, allowing for the standby drive to kick in to replace a failed disk, minimizing the time where you may be vulnerable to a second disk failure.
In the future when you need more capacity, you can replace each disk one by one, and when the last disk is replaced, you can create another volume utilizing the new available space. This is in contrast to X-RAID where the single volume expands over the new space. |
|
|
Volume capacity will be limited by the smallest disk. For example, if you are installing one 250GB drive and three 750GB drives, your data volume capacity will be limited to 250GB on each of the four disks. In Flex-RAID mode, you can utilize the leftover space on the 3 750GB disks by creating another data volume (3 x 500GB). With X-RAID, if you replace the single 250GB disk with a 750GB disk, your capacity will automatically expand, utilizing all 750 GB from each of the 4 disks.
|
|
|
NETGEAR will provide data recovery analysis and service for a fee. Each case will be vary in price based on time spent. NETGEAR Support can provide an estimate after doing an analysis.
|
|
|
ReadyNAS does not support JBOD, however, you can create a RAID 0 striped volume across all four disks or create a separate RAID 0 volume on each disk.
|
|
|
The ReadyNAS supports the optional disk sleep mode. In this mode, disks will go on standby after a specified time of inactivity.
|
|
|
ReadyNAS NV+, 1100, Rev. B NV and Rev. B X6/600 support scheduled power on and off. Rev. A NV needs add-on to turn on this feature, see add-on notes for details.
|
|
|
There is a limit of 32,000 users and 32,000 groups, however, depending on application, the ReadyNAS will support from 1 to 20 concurrent users. For large video files, the ReadyNAS can stream 4 HD-quality video without frame drops. For Microsoft Office-type applications, the ReadyNAS will handle many more concurrent users.
|
|
|
Filename length is limited to 255 bytes. If filename contains only alphabet and numbers, this limitation is the same as most of client. However if filename contains Germanic umlaut, Chinese character, Kanji, etc., filename will be limited to less charactors. The maximum filename length will be 85 characters if filename cosists of only Chinese charactors.
|
|
|
The ReadyNAS will support up to 1TB (terabyte) file size. Some protocols, such as HTTP will have a limitation where maximum file transfer size can be much less.
|
|
|
The ReadyNAS uses Linux Ext2/Ext3 file system. A typical Linux distro can mount and access the data from the disks.
|
|
|
0-40C. ReadyNAS will gracefully shut down if hard disk temperature exceeds safe level.
|
|
|
No, however you can attach a tape drive to a PC and backup files from the ReadyNAS.
|
|
|
You can use the built-in FrontView Backup Manager to backup shares to a USB disk, another PC, or another ReadyNAS. Alternatively, you can use a PC, Mac, or Linux backup software to backup shares from the ReadyNAS.
|

First of all, the NV+ is an evolutionary running production change over the original NV. In retrospect, the NV itself was already improving through running production changes, and a lot of features we are introducing formally in the NV+ hardware had already started appearing in the latest batches of the NV, starting in August/September timeframe. So pretty much other than the LCD panel, the hardware on the NV+ is very much the same as the "rev B" NVs that we have been shipping. That said, I will post the improvement in the NV+ since the original NV which was introduced back in February this year. Keep in mind that the RAIDiator firmware runs across commonly across the ReadyNAS family, so the software features remain the same.
|
|
|
Yes in almost all cases; however, it does degrade performance. The only case which does not support SMB signing at all is using the ReadyNAS built-in backup manager, with the Windows (Timestamp) protocol.
|
|
|
A simulator (emulator) of the ReadyNAS Duo FrontView web interface can be found here: ReadyNAS FrontView Simulator.

Please visit our Definitive Guide to the ReadyNAS Duo.
|
|
|
|
Yes you can! Take a look at our streaming media to the EVA8000 how-to.
|
|
Boot, Installation, and Upgrade |
|
You can depress the power button on the front of the ReadyNAS for about 5 secs until the disk LEDs start blinking, and then release. The shutdown process will take about 10 secs or so. Alternatively, you can shutdown from FrontView from the System→Shutdown page.
|
|
|
No, you need to have at least one disk installed before you can update to the new firmware. You can do a factory default with all your disks after the firmware has been loaded.
|
|
|
Yes you can, however, please note that the smallest capacity disk will be used to determine the overall size of your data volume. Also, your performance may be limited by the slowest of the disks.
|
|
|
Yes, however, the ReadyNAS will utilize the disks in SATA I (150MB/sec) mode.
|
|
|
Yes you can. But old data will not be able to be preserved, because of this, it is always better to start from factory reset when old disks are used. This will ensure that you have a clean installation on used disk(s).
|
|
|
After installation, delete the existing RAID volume and recreate it with one disk configured as a hot spare. Please be aware that X-RAID does not support hot spare.
|
|
|
Download the ReadyNAS firmware to your PC and perform a local update from FrontView.
|
|
|
You can force a re-installation of the firmware from flash to the disk. This is helpful if you have lost your admin password and want to set it back to default, if errors in your network settings has made it impossible to connect to the ReadyNAS, or if you suspect that the operating system on your disk may somehow be corrupt. The firmware re-installation process will not touch your data volume.
Here are the steps:
The firmware installation will begin from that point. You can monitor the progress with RAIDar. You admin password will reset to 'infrant1' (v3.01) or 'netgear1' (v4.0+). |
|
|
Simply download the add-on and upload it from FrontView System→Update→Local tab. You will need to reboot before the add-on is installed.
Some of the Add-on packages will not be removable after they are installed. Add-on packages that install a service can be removed from the Services tab. |
|
|
|
|
You can reset your ReadyNAS Admin password by accessing http://ip_address_of_readynas/password_recovery . If you have forgotten the password recovery answer, you will need to perform a firmware re-installation to reset the admin password.
|
|
Note: If the ReadyNAS is set for DHCP (default mode), it will appear as IP 192.168.168.168. |
|
|
The ReadyNAS supports up to 4 data volumes, but each disk is limited to 2 data partitions.
|
|
|
X-RAID mode is designed as a single-volume system, so only one.
|
|
|
There are several things that factor into the usable capacity of your ReadyNAS volume.
Raw capacity (GB = 1000^3) = 2000 Conversion to (GB = 1024^3) = 1862 Minus one disk for redundancy (-465) = 1397 Minus OS (10) = 1387 Minus RAID/Filesystem overhead (2%) = 1359 Minus snapshot reserved space (5GB) = 1354 Based on our calculation, the approximate usable capacity for a 4 x 500GB system is 1354GB. |
|
|
On ReadyNAS systems supporting disk hot-swap (i.e. NV, 1000S), you can take out the failed disk and replace it with a new disk while the ReadyNAS is online (there's no need to shutdown the ReadyNAS). Make sure after taking out the failed disk, you wait about 10 secs before inserting the replacement. On other ReadyNAS systems, you'll need to shutdown the ReadyNAS and replace the failed disk while powered off, and then power-on the ReadyNAS. Once the replacement disk is in-place, the disk will be initialized and sync'd into the RAID volume.
|
|
|
This depends on the size of the disk. Typically it'll take anywhere from an hour to several hours. You can monitor the progress in RAIDar or FrontView RAID Settings tab.
|
|
|
RAID 0, 1, and 5 are part of the Flex-RAID RAID levels. If you want to switch from this mode to X-RAID (expandable RAID), you will need to backup your data first, and then perform a factory default. During the factory default process, there will be a 10-minute window during the boot where you can use RAIDar to click the Setup and set the box to the desired RAID mode (Flex-RAID or X-RAID). RAIDar will prompt with "Click Setup" during this 10-minute period.
|
|
|
Never migrate disks if your volume is in degraded mode. Make sure the volume is redundant first. Then follow the steps below:
|
|
|
First, make sure the disk is at least as large as the smallest disk in the existing X-RAID volume. Then simply add the disk into the ReadyNAS. If the ReadyNAS supports drive hot-swapping (NV, 1000S), you can hot-add it while the ReadyNAS is online. Otherwise, you will need to shutdown, add the disk, and reboot.
The newly added disk will go through an initialization and sync phase. This can take several hours (e.g. 750GB disk can take about 7 hours). You will be notified by email after this is done, and you will need to reboot the ReadyNAS. Upon boot, your existing volume will either be made redundant if this is the 2nd disk, or your volume capacity will expand if this is your 3rd disk or higher. This is an offline process that can take several hours. You can monitor this with RAIDar, and you will receive an email when the process is complete. |
|
|
Replace one disk at a time with a larger disk, letting it finish initializing and syncing after each replacement (this process can take several hours depending on disk capacity, but you can continue access to the ReadyNAS), and after the last disk has been replaced, reboot the ReadyNAS. The expansion will occur at boot time. The expansion time will depend on your existing volume size, the ending volume size, and the number of files in your volume. Typically, it'll take anywhere from an hour to several hours. You will be notified by email at each step of the process.
Keep in mind that when your replace your disks, with ReadyNAS that supports drive hot-swapping (NV, 1000S), you do not need to shutdown the box before replacing the disks. Simply pull out the disk, wait at least 10 secs, and then add the replacement disk. |
|
|
ReadyNAS 600/X6/1000S (Rev A and Rev B) will restart automatically, however, ReadyNAS NV/NV+ will not. ReadyNAS 1100 is configurable by on board jumper (J6, Default is on).
|
|
|
First, make sure your memory DIMM is seated securely. It may have come loose during shipment. Otherwise, the flash image may be corrupted and will need to be restored. For NAND Flash based systems, please use TFTP Boot Recovery, for USB Flash or Compact Flash based systems, please use Raw-writer.
|
|
|
TFTP Boot Recovery is useful in cases where the ReadyNAS fails to boot, and you suspect the flash may be corrupted. Download the TFTP Boot Recovery package from here and follow the instructions in Readme.txt
|
|
|
Yes. You can download the TFTPServer for Mac here and use it instead of the Windows-based tftpd32.exe included in the TFTP Boot Recovery package.
|
|
|
If you are experiencing boot problems and TFTP Boot Recovery process cannot be performed, you can use the USB Boot Recovery instead. You'll need to download the latest USB boot recovery image for RAIDiator-3.01c1-p6 or for RAIDiator-4.01c1-p2 and write that image to the USB flash device. To write the image on a Windows PC, you'll need to use Rawrite32.zip. Make sure to click the Eject button after the write is complete. On Macs and Linux systems, you'll need to use the 'dd' command in the shell to write the image to the flash device(dd the image to the first partition of the USB drive).
Power down the ReadyNAS, insert the USB flash device, and depress the power button on the front for approximately 20 secs -- you'll see all the disk LEDs blink once at 5 secs, 10 secs, 15 secs, and 20 secs. Release the button right after the 4th blink. This will start the USB boot recovery process. Once the fan and the lights shut off and the lcd screen displays "Attemp", press the power button and the unit will boot up normally. Note: ReadyNAS boot loader does not support USB flash drives with USB hub built-in, if RAIDar does not detect NAS after 5 minutes, please try other brand/model USB flash drives or you can check if the flash drive has built-in hub using Windows device manager. |
|
|
You'll need to allow the ReadyNAS to automatically power-down for the auto power-on to work. Manually powering off the ReadyNAS overrides the automatic Power-On feature.
|
|
|
» I've enabled the schedule Power-Off/Power-On option on my NV, but now I cannot power-on my ReadyNAS. What should I do?
Note 1: This trick does not apply to NV+. NV+ will not run into this problem.
Note 2: If power is on momentary when press power button, the trick does not apply. (PSU is bad or there is circuit shortage somewhere) Older revision of the NV main board will get into this state if the Power-On event comes on while the NV has no AC, or if there was a power-outage during this time. To recover from this, you will need to reset the timer following the instructions here. When lift battery clamp in Step 3), please do it gently. |
|
|
|
|
Resetting the ReadyNAS back to factory default will wipe out all configuration and data. Please understand this before continuing. If you choose to continue, here are the steps:
There will be a 10-minute window where you can use RAIDar to change the RAID mode and/or select the snapshot reserved space. RAIDar will prompt with "Click Setup". If you do not click Setup, the installation will begin with the default settings. Otherwise, it will begin when you've confirmed your option selection in RAIDar. You can monitor the installation progress with RAIDar. |
|
|
Prior to RAIDiator 4.0, the default login and password is 'admin' and 'infrant1'. Starting with RAIDiator 4.0, login and password is 'admin' and 'netgear1'. Please make sure you change the admin password after doing a factory default.
|
|
|
» Will clients with non-jumbo frame network interfaces be able to access the ReadyNAS if jumbo frames is enabled?
Yes, the frame size will be negotiated down to the non-jumbo size with clients not supporting jumbo frames.
|
|
|
This may happen when ReadyNAS is configured to obtain IP address from DHCP server, but DHCP server does not provide IP when ReadyNAS request for IP address. When this happen, correct DHCP server problem, etc. And wait for a while or until ReadyNAS obtain correct IP address from Server. You can also unplug and then plug ethernet cable to force re-initialize network.
This may happen in below situations for examples.
|
|
|
ReadyNAS uses self-signed certificate. IE7 or Windows Vista will not trust this certificate unless you explicitly import this certificate by yourself. Below is brief procedure to import certificate.
Note for Vista Users: Please note that Windows Vista works different than XP. When you are using Vista, you need to specify ReadyNAS as "Trusted Zone", otherwise you don't see "Install Certificate.." button when viewing certificate. And while walking through "Certificate Import Wizard", you need to click "Place all certificates in the following store" radio button, and specify "Trusted Root Certification Authorities". (If you place a certificate in your personal store, IE will not trust it.) |
|
|
If you suspect that one of disks is bad and hanging system boot, please follow these steps to quick locate which one may be bad:
High ATA error count usually means that disk is failing. The best thing to do is to non-destructive test it on PC using vendor's tools, UBCD is one of the best disk utilities compilation, or simply replace the bad disk. The signs of bad disks: Clicking noise from disk, ACT LED flash only once or twice in half minute repeatly, No ACT blinking while power LED is not solid. General advises on bad disk handling: Backup data first, keep disks in original order, replace bad disk as soon as possible, never take more than 1 disk out of RAID. |
|
|
If your system has RAIDiator 4.0+ on it, and you are having issues with the Volume Check on boot up, it is possible to skip the volume check.
To do this, start with the system off, then turn it on, while depressing the power button for 5 seconds (1 long flash). Users with an LCD on their ReadyNAS will see '5: Skip Vol Check'. Skipping the volume check is not wise unless you are experiencing problems. It is wise to send your system logs to support for investigation to see why your volume check was having issues. |
|
|
You may be in a position where you need to deploy a custom configuration (plus data) on the ReadyNAS to a bunch of units fast. If that’s giving you nightmares, have no fear — there’s an undocumented but simple way you can do this, even if you have a thousand ReadyNAS boxes you need to replicate.
|
|
Expansion (X-RAID) |
|
If you have less than 4 disks, simply add your disk(s) to the box. You can hot-add it if your ReadyNAS supports drive hot-swapping (i.e. NV, 1000S). If your ReadyNAS does not support hot-swap, simply power off the ReadyNAS, add the disks and power on. The newly added disk(s) must be at least the same size as the smallest existing disk. Note that you can add one or more disks at a time. You will be notified by email and through FrontView that the disks will be initialized (this can take several hours depending on the disk capacity). During the initialization phase, you can use the ReadyNAS normally. Once the initialization is done, you will be notified to reboot the ReadyNAS. Upon reboot, the expansion process will occur (this can take several hours or much longer depending on your drive capacity and the number of files in your data volume). You can monitor the status via RAIDar. Upon completion, you will be notified that the volume has been expanded.
|
|
|
You will need to replace each of your disks, one at a time, with a larger one. Each time the disk is replaced, you will need to allow the disk to initialize and sync before continuing with the next disk. The initialization and sync process will take several hours or longer to complete depending on the capacity of your disk. With the ReadyNAS that supports drive hot-swapping (i.e. NV, 1000S), you can replace the disk online; otherwise, you will need to shutdown the ReadyNAS and replace the disk while powered off. Once all the disks have been replaced, reboot the ReadyNAS to start the expansion process. This will take several hours or longer to complete depending on the volume capacity and the number of files in your volume. Do not interrupt the process during this time. Once completed, you will be notified of the new volume size.
|
|
|
The expansion will still occur, but the expansion size will be limited by the smallest disk in the system. When you replace each of the smaller disks to the larger disk capacity, X-RAID will expand itself to utilizing all the space from this larger disk.
|
|
|
On a failure condition, we advise you to contact NETGEAR Support immediately and provide them with system logs and step you took to expand your X-RAID volume. Do not try to fix the problem yourself at this point as you may create a 2-disk failure condition that might make data recovery hard or impossible.
|
|
Performance |
|
In our performance lab, using IOMeter in sequential read/write test with the ReadyNAS NV, we can achieve 30 MB/sec on reads and 24 MB/sec on writes. This is using a Dell 2.8GHz PC running Windows XP Pro.
|
|
|
» What transfer speed can I expect when reading and writing large files like CD or DVD images to/from the ReadyNAS?
The transfer speed should be similar to what you would get with the above IOMeter test, except that you would have to take into account the read speed from your PC hard disk as well.
|
|
|
We've seen an increase of 12% on both reads and writes with IOMeter when going from the default 256MB memory to 1GB. Depending on the application you may or may not see any improvements. Typically if you will be indexing a large number of media files, running rsync backups, or accessing large folders, you will see improvements.
|
|
|
The ReadyNAS supports SATA II disks in SATA I compatibility mode. There should be little if any difference if the disk speed is the same. That said, performance will be limited by the slowest disk.
|
|
|
You can enable the Fast USB Write option in the Performance tab. You will need to properly unmount the USB disk if you select this option; otherwise, you should run a file system check on the disk before accessing it next time. With RAIDiator 3.00+, you can use the front Backup button to unmount and mount a USB disk. Depressing the Backup button for 5 seconds until the disk LEDs blink will unmount a mounted disk or mount an unmounted disk.
|
|
|
Performance can be a hard thing to measure with the ReadyNAS because of so many different user environments. Folks have different switches, hard disks, PCs, operating systems, and different OS settings. If you feel you have a performance issue, please run IOMeter following the instructions at /forum/viewtopic.php?t=265 so that we can ascertain where the performance bottleneck might be. Update to the latest RAIDiator release before doing so.
As a reference, our performance lab uses the following:
ReadyNAS NV
256 MB memory
X-RAID (X-RAID performance will show approximately 20% better than RAID 5)
4 x Seagate ST3500630NS 500GB drives
Jumbo frames enabled (MTU 7936)
Journaling disabled
Fast CIFS writes enabled
Dell 2.8GHz P4 PC
Windows XP Pro
1GB memory
Intel Pro1000 PCI gigE NIC
Jumbo frames enabled (MTU 9K)
Flow control and TCP offload options enabled
SMC 8505T
8-port Jumbo Frames gigE switch
Cat 5e cabling
Note that the PC is not highest performing system we can possibly use -- in fact, the PC was a $399 special including the LCD monitor. We utilize the iometer.icf file posted in the link above, creating a 1GB file on the ReadyNAS. The ReadyNAS is setup for Share security mode, and we run the same test in Domain security mode. We reboot the Windows PC before starting the test and do several runs. With the above setup, we can obtain: Read: 30 MB/sec Write: 24 MB/sec Troubleshooting Steps Your results can vary depending on several factors. The most common problems we see are the following:
|
|
|
Try setting TCP delay_ack to 0. Default is 3, which causes handshake problems with the ReadyNAS, causing severe performance penalty. You can set the delay_ack with the following command from the OS X terminal:
sudo sysctl -w net.inet.tcp.delayed_ack=0 If you want the setting to stick when you reboot, add the line to /etc/sysctl.conf. For reference, see: http://julipedia.blogspot.com/2006/02/samba-performance-under-mac-os-x.html http://mail-index.netbsd.org/tech-net/2003/01/28/0004.html |
|
|
The optimization performed on the ReadyNAS may adversely affect compatibility with some routers. To turn off this optimization, and thus providing better compatibility, change the MTU setting on the ReadyNAS FrontView Network tab to 1492 (from default 1500).
|
|
|
Here are some things you can try to improve Vista performance:
|
|
Services |
|
If you need to restart a service such as NFS, simple go to the Services tab, unselect the checkbox next the service, Apply, select the checkbox, and Apply. Disabling and re-enabling the service has the same effect as restarting a service, and no share access restrictions are affected during the process.
|
|
Share Access and Permission |
|
The private user home shares are available over CIFS or AFP.
|
|
|
» In User security mode, can ReadyNAS User A be able to access the content of ReadyNAS User B home share?
Users are restricted from accessing each other's home share. Only the Admin has access to other user home shares. If you want users to have mutual access privilege, create a public share, and put access restrictions so only these users have access to the share.
|
|
|
The home shares are created the first time users access the ReadyNAS. If a user has not logged in yet, then his home share will not have been created yet.
|
|
|
The option is available in the Accounts → Preferences tab.
|
|
|
Access the ReadyNAS over Explorer as admin user and the home share containing all user private shares is available.
|
|
|
In order to delete files under the current share in User mode, the following conditions must be met:
|
|
|
In Windows, right click on the file. Then select Properties, and Security. Verify that the user has the proper permissions to delete the file. If not, connect to the share as user admin and delete the files and folders using the admin privilege.
Sweeping changes to the ownership and permissions of the contents of a share can be made with the Advanced Options tab. |
|
|
Try appending the pound (#) sign to the end of the URL like this: http://$mynas/$myshare/#
Also take a look at our accessing ReadyNAS remotely with WebDAV how-to. |
|
|
You can setup a backup job between two shares.
|
|
|
» My share's default access is set to read/write but why am I still unable to read or write to a file?
In Windows, right click on the file, then select Properties, and Security. Verify that the user has the proper permissions to read from or write to the file.
|
|
|
You can create a batch file with the following contents:
net use e: \$hostname\$sharename $password /u:$sharename /persistent:no and place it in your Startup menu. Alternatively, you can use "Map Network drive" under "Tools" menu in File Explorer , and check "Reconnect at login" option. When you are using Windows Vista, "Map Network drive" GUI menu is at right-click on Computer in Start menu. You can also map sub-folder to drive. If you want to mount entire share to drive, you just need to right click on the sahre and select "Map Network Drive...". |
|
|
The Advanced Options tab can be used to change the ownership and permissions of the contents of the share. Keep in mind that these options are meant for advanced users and can cause access problems if used improperly.
|
|
|
Since NTFS support is Read-only (Note: RAIDiator v4 firmware allows write access to NTFS file systems), you can use either Ext3 or FAT32. Ext3 allows for better retention of file ownership and permission and may be more appropriate in a mult-user backup environment.
|
|
|
You can download an Ext3 driver for Windows at: http://www.fs-driver.org/.
Ext3 driver for OS X can be downloaded at: http://sourceforge.net/projects/ext2fsx/. |
|
|
From the command line, run
net use /delete \nas_name\share_name Also you can use "Disconnect Network Drive..." GUI. Use "Start" menu, and right click on "My Network Place" (WinXP) or "Network" (WinVista), and select "Disconnect Network Drive...". |
|
|
There are occasions where Windows' behavior of trying to connect using WebDAV first before SMB/CIFS causes a long delay. The easiest way to fix this is to just disable the WebClient service in Windows. You can do this from Windows by going to Control Panel -> Administrative Tools -> Services. From there, open the WebClient service, stop it, and also select the option to disable it at startup.
|

When accessing a file share on a remote computer or device, Windows Vista will refuse to send your password using older encryption methods.
Unfortunately, many NAS devices as well as older versions of linux do not understand the newer encryption methods. This keeps you from being able to access these devices. The solution is to force Windows Vista to use the older encryption methods. To do that, follow these steps: Users of Windows Vista Home Basic and Home Premium Click start Type: regedit Press enter In the left, expand these folders: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ In the left, click on the folder named: Lsa In the right, double-click "LmCompatibilityLevel" Type the number 1 and press enter Restart your computer. Users of Windows Vista Business, Enterprise, and Ultimate Click Start Click Control Panel Click System and Maintenance Click Administrative Tools Double-Click Local Security Policy In the left pane, click the triangle next to Local Policy In the left pane, click Security Options In the right pane near the bottom, double-click "Network security: LAN manager authentication level" Click the drop-down box, and click "Send LM & NTLM - use NTLMv2 session security if negotiated" Click OK. |
|
|
To maintain access compatibility with other protocols, rsyncd will transfer files as the share user in Share security mode. This means that files transferred to the NAS over rsync will be owned by the share user. To maintain UIDs/GIDs, use User security mode, or NFS mount the share with root-enabled hosts properly set in the NFS configuration tab in Frontview and do a pseudo-local rsync.

Remote Access over WAN |

Port-forwarding is a way of selectively allowing access from a WAN (Internet) to your LAN through your existing router firewall. Only the network protocol "ports" that you forward will be allowed access to a particular box on your LAN. For instance, if you want to enable only FTP access to your ReadyNAS, simply forward ports 20 and 21 on your router to the ReadyNAS IP. You can do the same for HTTP or HTTPS by forwarding ports 80 and 443.
Each router will have a slightly different method to allow this option. Here's a link that explains how you would do this with a lot of the routers on the market. This link courtesy of MrCyberdude. http://www.portforward.com/english/routers/port_forwarding/routerindex.htm |

Yes, you'll first need to configure your router for port forwarding. Ports 21 and the passive port range, which can be configured in the Services tab, must be forwarded to the ReadyNAS IP address. Also set the "Masquerade as" setting to your external IP address or domain name.

In the Services page, select Anonymous for FTP mode. Note that Anonymous FTP is the only mode available in Share mode.

» I can log into the ReadyNAS, but when I try to transfer files, the transfer rate almost immediately goes to 0 and eventually times out. What's wrong?
Try changing the MTU on your router to 1492. This is often needed when the ReadyNAS is connected to the Internet through a Cable-based broadband service.

» How can I access my ReadyNAS through FTP when my ReadyNAS is behind my home firewall and my client is behind my school/work/etc. firewall?
You will need to setup the ReadyNAS for passive (PASV) FTP. To do this, go to the Services page and setup the options under FTP. In this case, you will need to select a passive port range (in most cases, a small range of 10 to 20 ports will do) and forward it from your router to the NAS. You will also need to enter your public domain name or IP address in the Masquerade field.

Try forcing your FTP client to use active (PORT) or standard passive (PASV) mode. Extended passive (EPSV) is only needed to IPv6 networks, and is not supported by the ReadyNAS.

Depending on the security mode and FTP mode, you may need to adjust the permissions on these files and folders to permit access through FTP. In Share mode or Anonymous FTP mode, the NAS will see an FTP user as a user named "ftp". Ther |
