QNAP(TS-451) NAS experience equipment and basic knowledge
NAS (Network Attached Storage) Chinese is called “network storage”. It was an enterprise-level product in the early days and began to enter the home field around 08 years ago. When it comes to NAS, everyone should be familiar with: Synology, which is the constant innovation of the software (DSM system) ease of use, so that NAS really begins to be suitable for family & personal use.
The landlord has been paying attention to NAS for a long time. He always hopes that the manufacturer can launch a product that combines data storage/video playback/route switching. In the past 10 years, I purchased the flagship home router Buffalo WZR_HP_G300NH for the NAS environment. It has a Gigabit Ethernet interface. In addition to the routing function, it also provides download/cloud storage for external USB devices. But after the early adopters, this primary function is easily replaced by various online cloud services.
Time flies, the landlord’s router has reached the edge of elimination, similar products have not appeared. . . Until June of this year, the landlord saw the first 3-in-1 product Huawei glory cube, unfortunately its function is too simple, can not meet the needs of the landlord; follow-up did not see the traditional NAS manufacturers follow-up launch similar products.
A few months ago, the landlord took a scrapped notebook and tried to install Taihe Qunhui early adopters, only to really understand the meaning of the phrase “NAS manufacturers are originally software companies”, which is why NAS prices remain high. – “The genuine license price of various derivative software of NAS should be included in the price of the host”; through trial use, it also determined the determination to purchase a NAS. It coincides with the recent increase in wages, not much to say, buy and buy!
Why buy it?
As a rational consumer (si), buying thousands of digital products for me personally must have several reasons for buying:
1. Make photos and videos of your baby and family safer
The landlord and his wife do not like to take pictures, usually rely on the phone to pat. Unfortunately, the landlord’s wife lost her mobile phone when she was half-year old. She was busy with the baby and didn’t back up. She didn’t worry about the security of the public cloud and didn’t open the photo stream. This lost a lot of precious photos from birth to half-year old. .
After all, I have equipped the new computer with a storage combination of SSD+Raid1 to store family photos and videos. Unfortunately, nothing rivals laziness.
In the past one year, I have only exported photos once by hand. . . God taught me the truth again. The mobile phone bought by my wife was stolen again. Although I opened the photo stream this time, in order to capture the baby’s expression, the camera is a continuous shooting. The number of photos is thirty or fifty, and the photo stream can only store 1000 photos. (The default photo will not be uploaded by default), causing a large number of photos in the previous period to be lost again. The disaster is not alone, the memory card of my mobile phone is suddenly unrecognizable, and many parties can’t repair it, so the photos and videos of the children in my mobile phone are lost. It’s just miserable.
So much, just want to warn you about the importance of data security, the baby’s photo is lost, can make people regret for a lifetime! Regardless of whether you save your hard drive, USB flash drive, or CD-ROM, storage device damage is a matter of time. Although there are various cloud disks, I personally don’t have the habit of uploading private photos to public clouds.
Last month’s Hollywood icloud vent (zhao) door, after the US reading, the software user’s private photos leaked, can you still believe the domestic manufacturers’ exercises?
Of course, if the home computer hard drive fails and the data is lost, although it can be sent to a professional business to do data recovery, but the price is moving, it is not impossible to pay half NAS.
Besides lazy, with storage devices, but too lazy to save is also the reason for my photo loss. Therefore, I need a device that can automatically back up photos taken by the phone to a safe place, and is not easy to reveal personal privacy. I think it is only possible to solve it.
In addition, in the current era of the Internet, having a NAS and then using the mobile app provided by the manufacturer, you can watch the family photos and videos stored in it at any time, and you can easily share it with your friends. Iphone6 is not available. Need to buy a 64G version!
Applicable people: users who do not want to lose their baby’s cute photos and family image materials, work important materials; photography enthusiasts
2, Cloud service may be terminated
3, the private cloud is the peace of mind
NAS is the data center of the home. After using disk array technology, all the data will not be lost due to the failure of a certain hard disk. And through the various application software provided by various manufacturers, all the data stored in the family can be obtained everywhere, and can be shared with friends. There will be no more disappointing things like “reporting by other users.” The cloud that can control itself is the cloud I need.
With the built-in synchronization software, you can easily synchronize files on various terminals. Documents that have not been written during the day, are saved directly from work, and go home to continue working seamlessly.
Applicable people: users who need automatic synchronization and backup of private files due to work and other reasons
4, HD movies at any time, want to see and see
With the popularity of large-screen TVs, everyone is increasingly demanding video clarity. Although the volume of high-definition video is also increasing at the same time, broadband above 20M is slowly gaining popularity. China Telecom Optical Network is currently doing activities, many cities can be upgraded to 8M free of charge by 8M, and friends who have not upgraded have seized.
Downloading movies and dramas is probably something that every family will definitely do. With NAS, whether it is PT, BT or Thunder, Baidu cloud, you can start remote download anytime, anywhere, go home, whether it is even TV, or use a tablet, mobile phone, how to see no problem. And the power consumption is only less than 35 watts, compared to the desktop, the annual electricity bill is much cheaper!
Applicable people: HD movie collection enthusiasts, PT players
5, replace the various boxes
Radio and television have been moving in succession, and various boxes have been killed. So can NAS replace the box? I will tell you later in this article.
So the question is coming, which NAS technology is strong?
In the home field, Synology has a better reputation for software quality & ease of use, and is now moving towards professionalism. In the commercial sector, QNAP is stronger in data security and professional functions, and is also making unremitting efforts to capture home users. It is very appropriate to describe the two NAS vendors with the same way.
To be honest, the functions that ordinary users will use, the current two products can be done very well. It is nothing more than a slight difference in ease of operation and UI aesthetics.
So first of all, I personally pay more attention to data security, so I initially planned to choose QNAP’s products. As for why Weilian’s NAS security performance is better? The main reason is that it has a more DOM card on the hardware than Synology’s NAS. The NAS-specific operating system is installed in the DOM card. It will not be booted due to the damage of the hard disk, and the boot status will not be frequent. Reading the hard disk is good for disk health and hibernation (personal point of view). In contrast, Synology, because there is no DOM card, its operating system is installed on the user’s hard disk, the only benefit may be to effectively reduce the cost.
Secondly, the group’s DSM system can be freely experienced because it is cracked, and the freshness is not so strong. I hope that the future version of DSM can solve this problem better.
The earliest to know this series of products stems from CHH’s evaluation of the x51 series 2-position TS-251. The wheel said that because of the black group, the home NAS market has suffered more or less impact. However, this also brings a benefit, that is, NAS vendors finally realized their own hardware shortages, began to make changes in the NAS hardware configuration, and developed new features in conjunction with new hardware.
QNAP TS-451 is one such product: it uses Intel’s latest X86 architecture Celeron J1800 2.41Ghz dual-core processor, and can be up to 2.58Ghz; the biggest feature is: it has built-in HDMI interface, And support MCE remote control, with QNAP QvPC technology, can be directly connected to the TV through the built-in XBMC open source player to play HD video stored in the NAS, and even connected to the monitor and mouse, it can be used as a PC use.
Some people may think that this feature is of no use, and it is more powerful to have a box. But the landlord doesn’t think so, not only is the TV cabinet more refreshing, but at least one remote control is also excellent. This is also the function that I have always hoped that NAS can provide. It has finally been realized. It must be it. It doesn’t matter, buy it and buy it!
In addition, the current development trend of NAS is to reduce the core of the system itself, and a large number of applications are presented in the form of APP, what functions users need, and can be downloaded by themselves. Thanks to the second development platform of QNAP, it is temporarily ahead of the group in the number of APPs. Of course, some application quality may not be as good.
The delay in the listing of the same level of product DS 415+ before the group was also one of the reasons why the landlord decided to try the China Unicom. Up to now, 415+ should already be available for purchase. The price comparison is slightly more expensive than TS-451. For consumers, it is basically a trade-off between DSM system and HDMI interface.
Let’s pay attention: x51 series positioning is only high-end for home, you can also choose enterprise-class x53 and x70 series products!
Simply show the device
The landlord has no interest in photography, and there is no good equipment. The quality of the slag is good to see, and this is definitely not the focus of this post.
It is a pity that the x51 series does not use metal material. Fortunately, there is no cheap feeling in the real machine. The host uses white/golden color matching, and the texture is good.
The landlord because this is the first time to write this post, so the current family portrait is like this. Note that the remote control is not standard, it is the landlord to spend money to buy a drop.
The remote control close-up can also be replaced by the mobile client Qremote.
The power supply is produced by Delta, and the global voltage is adapted.
The front interface, the two buttons are the power switch, one-key import, and the bottom is a USB3.0 interface.
The back interface is divided into HDMI, 2 precursor Ethernet interfaces, two USB2.0 interfaces, one USB3.0 interface and power interface.
The un-locked hard drive bay supports both 3.5 and 2.5-inch disks.
I almost forgot to take Seagate’s NAS dedicated disk, because the Western Digital Red Disk is really aesthetically tired, and tastes different tastes.
Looks like the firmware reasons, with the commonly used HDtune5.5 test to half of the error will be interrupted, the previous reading of the curve and seek indicators, the performance is stronger than the red disk. The noise and vibration are still running, and the red plate personally feels half a catty, but the head moves louder and louder.
As for whether it is necessary to purchase a NAS dedicated hard disk, benevolent people will see it.
The most important thing about the NAS disk is the addition of an error recovery control function. Each name is different: TLER (Western Data) / CCTL (Toshiba) / ERC (Seagate); previously there is no such thing, nothing more than an ordinary hard disk plus a dedicated Firmware thing. After the emergence of the NAS disk, the manufacturer saw the sweetness, and the other way to make the normal disk open error recovery control is gone. The magic is that the two Toshiba 2T ordinary plates that the landlord bought last year actually took it. Checked that Toshiba’s DT01ACA200/300 (only 2TB and 3TB) clearly supported these two, but this year’s new support does not support the landlord.
The landlord thinks that if the group Raid, it is necessary to buy the NAS disk. After all, I have seen many examples of the special situation because of the special situation. Then I think that the quality of the warranty is longer and the quality should be better than the ordinary one.
Connect to the TV to see the XBMC playback interface
The landlord actually has radio and television HD, telecom IPTV and Haimeidi H7. With TS-451, the Android box can be used for the main bedroom TV.
The landlord is also the first to use QNAP’s NAS. It feels that this toy is not easy for ordinary people to get started. Many functions need to take a little time to study. So with this article, one is to make a record, the second is to share with my friends who are interested in NAS, if you can get a reference in the future.
The landlord believes that the user base is the source of the product that is getting better and better. I hope this post can bring more users to QNAP.
The official Q&A is also very detailed. If you don’t understand it, you can read it first, maybe you can solve your problem.
I will introduce this product according to the installation and setting sequence of the machine, and how to do it from the perspective of how to implement a certain function. Instead of the general post, a brief introduction to several NAS built-in stations will be done; because I personally After reading those posts, I could not provide enough help for the difficulties I encountered. My personal recommendation for the product or function may not be mature or even misunderstood, but I still hope that friends from QNAP manufacturers can see and make changes.
As for product performance, you can refer to the CHH test, this level of product, running full of gigabit no problem. My house was renovated early, and the Amp is more than five types, which can achieve this speed.
The tutorial begins, and see how Weiliantong thinks
1. Initial installation process, all the following demos are based on QTS 4.1.1 version
QTS is the operating system of the QNAP NAS device. For the first time installation, please use the browser to access the [http://start.qnap.com/cn/] page. There are process installation instructions, followed by cloud installation and local installation. The way, personal recommendation chooses the local installation method, download the Qfinder software provided in the page.
Before installing the QTS system, the first is the hardware installation. You need to insert the hard disk first, connect the power cable, network cable and access the home network, and then use the computer to access the above page. After success, please choose your own NAS model.
Here we use the dedicated installation software Qfinder as an example to illustrate the installation process. After running Qfinder, the software will automatically search for the properly connected NAS within the LAN. The router will normally enable DHCP, which will automatically obtain an internal management IP. Follow-up generally select “Manual Settings”.
The landlord began to put two new 4T Seagate NAS dedicated disks into it, and successfully recognized it.
It is no problem to put the two-disc machine directly into two hard disks, but the four-slot machine landlord does not recommend this, the reason is later.
Set the management account password, remember, after a few days, I seem to have not found the place to retrieve the password, can only be initialized? Here you also need to choose how to use the disk, which is described in detail later.
Going down to the network settings, the landlord strongly recommends setting it to a fixed IP to prevent IP address changes. Remember to do MAC binding on the router.
Installation begins, first check if the firmware is the latest version, the first time the landlord updates 4.1.1 firmware takes about 40 minutes, the speed is slow, and for the China Telecom’s DNS, the scientific Internet export in Hong Kong is invalid, patiently waiting for completion Let’s go.
The Qfinder software will also automatically pop up the email settings. After the setup is successful, one can receive the alarm information. In addition, the shared file sharing link on the NAS can be automatically sent to friends by email.
Fill in your usual email account password, the initial installation ends here.
If you use the factory reset function later, you can directly access the management IP to access and install it. The interface is slightly different. The front part that can directly be used in the next step is not on the map. The network part has more DNS settings. In addition to the commonly used 8.xx 114.xx, the standby DNS can also try to see Taiwan Chunghwa Telecom’s DNS 188.8.131.52.
There is one more page here, which can directly set up related network services that can be opened, and the landlord decisively opens all.
The way the hard disk is used is more intuitive.
After the installation is complete, you can access the QTS management page by directly accessing [http://xxxx:8080] in the browser. xxxx is the IP address of your NAS in the LAN.
2, Raid brief introduction and use selection
The Raid function is the basis for NAS to implement secure storage. Another method is to use backup software to make multiple disks or even remote backups.
The former is worry-free and convenient, but it has a huge waste of disk space; the latter has higher technical requirements for users, but it saves disk space.
For the lazy guy of the landlord, it is natural to use the Raid method to achieve it.
Note: It is still necessary to emphasize data security. With NAS, it is not foolproof. Quote from PCEVA a big word: “The disk is RP, the data is lost by yourself.” Data security is a matter of habit, and RAID doesn’t make your data more reliable. RAID is passive and it can’t change your storage habits. Even the most reliable RAID 1, if it is neglected, will still cause data loss. When the hand owes it to delete the file, and then overwrites the file storage location, no one can save it.
Supplement: The landlord looked at it. The above problem seems to be solved by the network resource recycling bin that comes with the QNAP NAS. By default, all deleted files are stored within 180 days.
Raid, the disk array, you don’t need to study so much, you remember that the home NAS within 4 bays, you only use three Raid methods: Raid1, Raid5, Raid6.
Note: Currently, “soft Raid” is used on the home NAS.
The mirror structure requires at least two hard disks to allow data to be recovered when one of the hard disks fails.
Advantages: The highest security, your data will be stored on two hard disks at the same time, so after hanging one piece, the data of another hard disk can usually be retained (the two hard disks together are seriously faulty, go buy lottery tickets).
Disadvantages: Disk utilization is only 50%, and two hard disks are limited, otherwise it will cause great waste (actual use space 1/n); disk performance is low.
The landlord strongly recommends the 2-bay NAS device for storing family photo videos and the 4-bay NAS to use this Raid method. Don’t forget the original intention of purchasing NAS.
At least three hard drives are required to allow data to be recovered if one disk is damaged.
Advantage: High disk utilization, the actual available space is (n-1/n), that is, 3 3T hard disk groups Raid5, and the available space is 6T.
Disadvantages: Less secure. Under the premise of current disk quality and large capacity, once the disk enters the degraded mode, please back up the data immediately. Don’t try to add new hard drives to rebuild data online. The time is not touching, the success rate is extremely low, and once it fails, it will cause data loss.
Strongly not recommended for home users! (In fact, some small servers in some enterprises have also banned the use of Raid5 in recent years)
At least four hard disks are required. It is an extension of Raid5, which allows two disks to fail. The actual disk utilization is (n-2/n), that is, four 3T hard disk groups Raid6, and the available space is also 6T.
Raid6 and Raid10, which are not introduced, are all related to the multi-bay NAS. The friends of the 4th position are just fine. Although they are available, they are not recommended.
Raid data reconstruction
With the Raid disk array, once a disk fails, Raid enters the degraded mode.
In theory, you can replace the failed hard drive with a new hard drive, and the NAS will automatically start Raid data reconstruction.
Note that this time is based on the amount of data, it will be very long, and the disk can be read and written continuously for several days. So in this process, the possibility of other disks failing again is there.
For data security, it is recommended to back up the most important data before attempting to rebuild Raid.
The two 4T Seagate NAS disks bought by the landlord are bad. After entering the QTS system for the first time, there are warnings in the resource monitoring and disk information in the lower right corner.
This is how the resource monitoring area looks good, usually green.
After hanging up
Disk information also has an alarm
Fortunately, Jingdong’s after-sales invincible, has passed 15 days (in fact, the landlord saw the first special offer of the Seagate NAS disk first smashed two hard drives, only to think of having to buy a NAS, NAS has exceeded the return period after the arrival of the goods… ), or give a new one. The landlord is out of stock, and the truth can only be refunded. After I explained to the senior customer service that the NAS hard disk needs to be used in pairs, the special agent helped me to transfer a piece from Guangdong. I must give a compliment.
After reinstalling, the automatic reconstruction began. The landlord was basically empty, and it took about 8 hours to rebuild and synchronize. If it is full or Raid5, it will be loose for a few days.
If you don’t have an intuitive understanding of the disk Raid space, you can visit the website of Synology. There is a very easy to understand Raid space calculator: https://www.synology.com/en-us/support/RAID_calculator
By the way, QNAP has a gap with the group in the details of the website. I hope that QNAP can refuel and can do the same Raid calculator page. Of course, it may be the reason why my eyes are not well found.
In addition, you can compare the contents of the compatibility list page of both parties, and you will find that Synology keeps up with the trend of the times. Other accessories supported, such as routers and UPSs, are very complete. For QNAP, the compatibility list is not perfect, of course not. Said that the things on the list are not supported by the Unicom NAS. For example, each flagship router is not in the compatibility list, but obviously you can definitely use it when you buy it back.
3, the establishment of the disk area, shared folder and permission settings
NAS’s operating system is based on Linux, so its basic concept of disk usage is very different from that of Windows.
For the QTS system use of the QNAP NAS only, in addition to the initial disk area setup when installing the system, additional operations require its built-in “storage space manager”.
The disk area here is similar to the Windows partition. The difference is that Windows partitions can be divided into N zones on a hard disk. The disk partition here is built on a separate disk, or on a Raid.
For example, TS-451 is a 4-bay NAS. I temporarily use 3 hard disks and divide two disk areas.
Among them, the Qnap disk area is based on my Toshiba 2T single hard disk; the MyData disk area is based on the Raid1 I built with two Seagate 4T disks.
If you use a 2-bay product, such as TS-251, you don’t need to worry about it, or you can use two single disks to create two volumes; or you can create a Raid1 directly and use it as a single disk.
But if it is a 4-bay product, my personal suggestion is this (not necessarily a misunderstanding):
First insert a single hard drive, not bad money to buy a NAS disk directly, like the landlord is relatively poor, buy Toshiba 2T or 3T ordinary disk, after the installation began to install QTS system.
What is the purpose of doing this? Although the system core of QNAP is on the DOM card, after you install the QTS system, it will automatically generate several system directories in the disk area that was first established, and the various APPs that you install separately, the content and configuration seem to be stored in the initial Under the disk area. Especially for friends who have download requirements, download and upload will continue to use the disk. If you install two disks as Raid1 as soon as you come up, it means that these two disks can hardly enter sleep mode and reduce disk life. Some people may say that the cache directory can be changed, but some applications such as remote Thunder, the download directory landlord will not modify.
Therefore, I recommend that the Qantas NAS of the 4-bay first use a single hard disk to install the QTS system, set it as a separate disk area, and then install various APPs, so that the shared directory and the APP cache directory will be installed. Built on top of this.
At this time, you can shut down, insert the two disks you want to do Raid1, reboot, set up Raid1, and set it as a disk area separately. In this way, you can only store important data in this disk area. When not in use, these two disks can basically be in sleep mode. I think there should be some benefits to disk life and data security.
Now let’s take a look at the “Storage Space Explorer”, first of all the “Overview” page, where you can see the basic information of the disk on the NAS, and you can create a new disk area here.
Click on “New Disk Area”, the “Disk Area Creation Wizard” will pop up. Here you can choose which new disk to use, use it alone, or use various Raid modes, and then you can see the estimated actual space available.
A spare hard disk is a blank disk. If you use the single disk + dual disk Raid1+ spare disk, the backup disk will start to take effect immediately after one of the disk failures of the Raid1. Disk, start data reconstruction. This feature is not necessary for personal use.
Click on “Hard Disk” on the left to see the details and health of each hard drive in use.
This Toshiba 2T, the landlord, can see the technology that supports error recovery control. (Seagate translation is recovery, here is the reply)
Here you can also do a disk health test, the landlord’s suggestion is not to idle to test this thing, this is the same as buying a desktop hard drive with MHDD first, in addition to let the hard drive hang faster, no meaning.
Click on “Disk Area” on the left to go to the page that operates on the volume. Here, you can perform operations such as “rename formatting to remove expansion” on the volume.
The landlord suggested that if you need to expand, please ask the official customer service before you get the relevant advice.
Let’s talk about the Bitmap function. If you use the Raid function, it is recommended to turn it on, which can reduce the time required for data reconstruction.
Finally, you can also see a list of shared folders created on each volume. You can see the initial disk partitions. There are a bunch of folders created automatically by the system. I don’t know because I didn’t see the official instructions. What are the uses of these folders, can you delete them?
After the disk area is built, the next step is to establish some other users. Click “Permission Settings – User” to enter the settings interface, take a look at the picture, not much to say here, very understandable. Emphasize that you should never use a simple password, and it is best not to give other users admin privileges.
Let’s talk about the establishment of shared folders and the settings of their access rights.
QTS shared folder creation, please click “Permission Settings – Shared Folder” to enter the settings interface.
First create a new folder to see, click “Create – shared folder”, the name is the name of the folder, indicating that you fill it casually, the key is to choose a disk location, the single disk area can be ignored.
Here I choose to be in my Raid1 volume MyData, then you can set the access rights of each user, there are only three kinds of permissions:
RW: Read & Write, means full access, delete, create data
RO: Read Only, read-only, cannot delete and create data
Deny: Denied access, no access
The following is the advanced settings, the more useful here is the “media folder”. After this selection, if you put video photo music into this folder, NAS will automatically scan it and add it to your media library. If you don’t choose it, it won’t be, so don’t open your personal privacy folder.
Whether it is hidden or hidden should not be seen under Windows, but you can access it by directly entering the correct path.
Also emphasize that the NFS permissions are set here.
NFS is a network file access protocol. You need to open this function by accessing the movies stored on the NAS using various Android boxes.
For example, your movie is placed in the Download directory, and the permissions are changed at the access level:
The default is to deny access, so you can only read it. If you use a box, or some player that supports NFS, you can see the contents of these directories.
For a more detailed explanation, check out the official documentation [http://files.qnap.com/news/pressresource/datasheet/TS-269H_CN.pdf]
4, the use of UPS uninterruptible power supply
Buying NAS is for data security. There are countless examples of disk damage caused by sudden power outages, power surges, and the like. The average computer of the landlord is estimated to be five or six hundred. Each time the power is cut off, at least two or three colleagues’ hard drives will be sacrificed. One does not do two, in order to secure the data on the NAS, the landlord decided to buy another UPS.
Domestic purchase is still recommended APC products, I bought APC BK650. This machine is not very good to buy, the common e-commerce variety is out of stock, and finally Amazon third party to start.
This UPS has a data communication line. After the USB interface is connected to the NAS, if there is a power outage, the UPS will notify the NAS that the power is off, and the NAS can automatically shut down within the set time. Avoid the UPS power exhaustion, equivalent to the power outage effect, resulting in hard drive damage.
Note that similar models of the BK500 do not seem to have this feature.
UPS looks like this, because the built-in battery, it is really a heavy, business is not 包邮, shipping costs are dozens. The landlord suggested that there is still no goods in the local computer city.
Before looking at the picture, I thought it was a big point socket, the result. . . I knew that I bought the more expensive BX650 and I can stand it up.
This is the data communication line
You can see the prompt message after entering the QTS system.
In the “System Settings – External Devices – Uninterruptible Power System”, you can automatically shut down after setting a few minutes. The default is 5 minutes. I changed it to 1 minute for insurance.
Needless to know, it was discovered that it was 3-5 points in the night, and our garbage community often flashed for dozens of seconds.
5, myQNAPcloud cloud service and router port mapping function introduction
The port mapping on the router has an important role for the use of the NAS, and must be taken out separately.
First of all, what is port mapping? The basic understanding of the landlord is as follows:
If you want to visit one of the families in a courtyard, you must first find out the specific address of the courtyard.
After getting the address, you went to the door of the courtyard, but found that you do not know the specific location of the family you want to visit.
To solve this problem, there may be two situations:
One is to make and place a sign at the entrance of the courtyard, telling the visitor that the A household lives in the north and the B household lives in the east. . .
The second is that you arrived at the door, do not know how to go, found that there is a speaker at the entrance of the hospital, in the repeated cycle brainwashing, A household in the north, B household in the east. . .
In this analogy, the process of visiting your guests is the process of trying to access your home NAS through a web page or mobile app in an external network environment.
To get the specific address of the courtyard, you need to rely on the Unicom’s myQNAPcloud service (or third-party DDNS service).
Because the current domestic network environment, home broadband is not a fixed IP address (equivalent to the random location of the courtyard), when you register myQNAPcloud service, your NAS will visit the QNAP server, telling the Union’s current public The IP address of the network (every time you restart the route, or re-connect the network, the IP address will change), which is equivalent to doing GPS satellite positioning for the quadrangle, so that you can know the latest address after changing the position every once in a while.
Therefore, myQNAPcloud is also its own DDNS service. Of course, this service is free. This is one of the reasons why NAS devices are more expensive. The free NNDS service on the market is not so stable and convenient. If you charge, the commonly used 3322 public. The cloud dynamic domain name is also 168/year.
Supplement: After this post is written, QNAP and Peanut Shell become partners, and the Peanut Shell App is available in the App Center. It is recommended to use it. It is always good to have one more road.
First of all, you must first go to the official website of the peanut shell ([http://www.oray.com/]), and receive the free domain name, then fill in the relevant information in the app:
You finally found this quadrangle, the equivalent of your access request to the router at home. The NAS is connected to the router. Its neighbors also have computers, tablets and mobile phones. How can we further access the home NAS through the correct path?
Here I want to talk about the concept of a port. Simply put, the port is the path and channel in the metaphor. The software in all the devices connected to the router, if it wants to communicate with the external network, has separate access channels. Generally speaking, there are a total of 65,535 channels. Some channels here are fixed lines. For example, if you use a browser to access a web page, you can access it from port 80 (channel). However, most of the channels are idle. Various software can be used randomly, or you can set a fixed port. For example, the default web access port of QNAP is 8080.
Now, when you arrive at the entrance of the courtyard, you will find a road map, telling you that you can reach the A (NAS) by going to the 8080 (north) and not going to the B (iPad).
The process of making this path map by hand is called port mapping.
If you arrive at the door, you will find that the speaker of the courtyard is playing the A household in the north. This shows that the hardware condition of the courtyard is better and will inform the visitors of their own internal access channels. This process, similar to the uPnP function of a router, is equivalent to a fully automated port mapping.
The default web access port of QNAP is 8080. On the external network, you should be able to access your own NAS by entering XXXXX.myqnapcloud.com:8080.
Among them, XXXXX comes from the information you registered myQNAPcloud. In an external network environment, XXXXX.myqnapcloud.com is equivalent to 192.168.XX on the internal network when you are at home. If you still use the peanut shell free domain name, then enter XXXXX.ovip.net:8080 should also be accessible. Note: This port of 8080 is customizable and variable!
Let’s take a look at the specific registration process. Click on the “myQNAPcloud” icon on the QTS desktop:
Start registration, myQNAPcloud’s service account is the mailbox, the password is also independent, and has no relationship with the NAS management password:
Will automatically detect whether your router supports UPnP port mapping, the landlord’s route can not support:
Here to register a myQNAPcloud host name, note that this domain name prefix is not permanent, once you quit the service, it is considered to automatically give up:
Note that there is another application in the Unicom cloud service called “CloudLink”, which should be used in conjunction with myQNAPcloud.
Almost all routers now support uPnP, but NAS may not be able to support all routers to achieve this. So try to buy the routing model in the compatibility list.
For example, the Buffalo WZR_HP_G300NH of the landlord has opened the uPnP function and is still not supported. It can only do port mapping by itself. Fortunately, this router supports third-party firmware, and DD-Wrt is used to solve this problem.
In general, it is recommended that you use the uPnP function to implement automatic mapping of common ports on the NAS.
However, some APPs of NAS do not support uPnP functions. For example, the commonly used download client transmission, the port number used is 51413. For this port, you must do manual port mapping. Otherwise, there will be no upload. No uploads, no need to play PT.
Suggestion: Modify the 8080 port used by default. This port is often blocked by some ISPs. Click “System Settings—General Settings” to modify this port. Take 8888 as an example.
Open the myQNAPcloud application interface, in the remote access service – automatically set the router, you can see whether the router is supported, and the list of commonly used port numbers for the automatically mapped system, you can enable or disable each active port as needed.
Let’s take the common third-party firmware DD-Wrt as an example to talk about how to manually add port mapping.
Find port forwarding (translation problem)
Fill in a name in the application to distinguish each mapping entry;
Protocol, optionally TCP/UDP or both;
DD-Wrt’s Source Net is special. Generally, the firmware does not have this option. DD-Wrt must fill in 0.0.0.0/0, which means that all external access requests are mapped. As for why you fill it, you don’t understand. Don’t get entangled;
The source port and the destination port are usually the same. Fill in the port that an application needs to use, such as the transmission of 51413.
IP address, which device you need to forward this network access request to under the router, such as my network, NAS is fixed IP 192.168.7.2, computer IP is 192.168.7.5, then Transmission is NAS, So here I have to fill in the IP address of the NAS: 192.168.7.2;
Note: After you add DD-Wrt, you can save the settings at the bottom of the point. If you add a point, you will generate one more to let you fill it out.
Finally, after doing any of the above, remember to save and restart the router for it to take effect.
Domain name / IP can enter your domain name registered by myQNAPcloud
The landlord explained that this has done its best. If you still can’t access the NAS from the external network, please contact the official customer service to help.
6, QTS console common options
The console is the place to modify the settings of the NAS. The landlord is also used in a shallow way. I will recall some of the places that may need to be modified.
The system sets a large item :
System communication port : It is recommended to modify, do not conflict with the port used by other software, do not understand the change 8888
Language code: change to Simplified Chinese
Login screen: modify it according to your own habits
Protection settings – start network security protection, generally changed to 1 minute failure 5 times permanent blocking. If you change your password, mobile client access errors may be killed by mistake. At this time, first turn off this function, and then go to the previous security level to empty all blocked IP addresses.
Power recovery: The default is the state before the recovery, I suggest that if you go home normally every day, it will be more insurance to keep the shutdown.
Power scheduling: I personally set up an automatic restart every Tuesday night in the morning. Don’t know if this habit is right?
SMTP server: set a mailbox, can accept notification of abnormal status
SMSC server: This is more troublesome. You should be able to receive SMS notification after setting. The landlord does not use this function.
Alert notice: Modify it according to your own habits
Here you can restore the factory settings, there is nothing to do with Raid1, the landlord restored 1 time, Raid1 empty disk synchronization will take 8 hours.
If you use an external disk, you can control it here, I have not used it, only explain the UPS uninterruptible system.
If you use the UPS and the landlord is similar, use the USB cable to communicate with the NAS, such as the UPS section of the map settings, the default is 5 minutes, I changed to 1 minute.
System online record: If you turn on security protection, you will be notified of the blocked IP record. There is nothing on the network to scan too many broilers, and the notification is too much trouble. You can turn off SSH notifications within your preferences.
Network service items :
Win/Mac/NFS: Corresponding to Microsoft, Apple and Linux operating systems, forget which ones have been opened by default, anyway, the landlord is all open
Service exploration: UPnP service, be sure to open
Application service items :
HybridDesk Station Hybrid Desktop: This is the exclusive feature of the x51 and other higher end series of new machines, which are described separately below. Note that if you want to enable the hardware acceleration of the NAS, you must open and install the CodexPack component. For the first time, this component goes into the installation from the QTS desktop shortcut.
DLNA Multimedia Server: Friends who use DLNA can open, I personally don’t need this
Multimedia management: You can set your own created folders as media folders. Photos, videos, and music placed in these media folders will be automatically scanned by NAS’s media cabinet function, and then automatically in Photo, Video, See these resources in Music Station.
Transfer management: If you need to transfer the video, the relevant process can see the details here. You can also open the auto-transfer folder here, which is generally not necessary.
Other projects will not be elaborated, either there is no need to modify, or the landlord does not understand, has not used, interested friends to slowly study.
7, APP installation
As mentioned earlier, the current development trend of NAS is to reduce the core of the system itself, and to present a large number of applications in the form of APP, and the mobile phone is a concept. Everyone uses it every day, I will not say more.
Enter APP Center, which one you like, install it. Do not like it or remove it if you don’t need it. When the software has a new version, there will be a prompt, you can upgrade directly.
Note: You can manually install the app yourself, in this position in this picture.
For example, when the landlord starts, the official Thunder Remote APP 0.9.29c has a bug, and each time the installation can be normally connected except for the first time, the connection fails again.
Later, I found the old version of 0.9.27c on the Internet to solve the problem.
This is what I said. The larger the user base, the better the product will be. Such an obvious bug, I don’t know how long it has existed, and few people have to give feedback. The official does not pay attention, and naturally it is not revised.
I feedback about 1 week, the official upgraded Thunder to the 0.9.31c version, and solved the previous bug. But I hope to fix it too. The default application opening is not maximized. Thunder can’t see the open wool. It must be maximized.
