A. Space-type
1. How to view the size of space
After you log in to FTP, you will see in the Information box
Maximum disk Quota limited to 300000 Kbytes (your space is 300M)
Used Disk quota 10000 Kbytes (you've used 10M space)
Available 290000 Kbytes (you still have 290M left space)
2. Why rent space can not do local online and download
Before we say this, we have written a quote from a domestic server custodian:
Download, music, movies can use the following broadband services:
Maximum use of 10M broadband fee: 10000 yuan/year 7000 yuan/six months
Maximum use of 20M broadband fee: 18000 yuan/year 11000 yuan/six months
Maximum use of 30M broadband fee: 26000 yuan/year 15000 yuan/six months
And that's what they mean to you in shared bandwidth. And is not really let you use these and whether they really rented so much bandwidth, the ghost ancestors know. Real exclusive Broadband 10M Beijing market average price of 10M million a year, 100M exclusive broadband minimum price in general around 700,000 yuan.
Finally said we, the server put in the engine room, do the virtual host and do download have separate price, see the above introduction, if you in hundreds of yuan rent space in the local online and download, this very definitely huge loss of things you said we will do to make you do? Some users also said: I only have more than 300 m of things! We were dizzy.
So now all of China's virtual host in the site is written on the world, online, download the class does not make statements. Many users in the heart we also understand that is to become famous after advertising to make money, not no, the Chinese webmaster station is a good example, spent a year, now monthly tens of thousands of of advertising revenue, a lifetime do not have to look for work. But they started out as a server, a little bit to do, light tens of thousands of software to collect the body will spend nearly 1 years of work, many people want to rent a hundreds of-dollar space with the way to add hotlinking (or put in rented space) want to be famous, is not a bit possible. If you want to be famous, you must pay!
Of course, we also see some 1G space hundreds of yuan advertising, they are bound to spend thousands of yuan rental 100M share, if they are spent hundreds of thousands of rent exclusive, kill us 100 times up will say: we do not believe. This lets you do it, its download speed is conceivable. You will also have to spend hundreds of yuan rent 1G space to achieve their desired results and shout everywhere: I also injustice than Dou! Although spend hundreds of yuan to rent a space to do local download in the minds of the sensible is how ignorant is not feasible. The true and false and how long they can not disappear, it depends on your own cheap heart can endure how long.
3.1G space Friends don't know what you're thinking
We found some friends to 1G space, we do not have to ask, 99% is to do online and download classes. Is it possible to use rented space? We have answered the question "Why rent space cannot be done locally online and downloaded" above.
Finally, we have to make a statement, don't ask us, we do not do.
4. Are our enhancements really unlimited online?
Enhanced IIS connections The number we set is 9999, some friends ask: Thousands of people online really can? This is of course impossible, we have a server generally at the same time IIS connections between 500-1000, if you are a user to occupy half of the resources, even if practical, but this huge loss of business we do not need to do a little.
However, many users say that their site will be able to thousands of people online, but actually we do now, more than dozens of people at the same time online did not see a few. Because most of them are personal behavior, just have time to come up to maintain, so want to do thousands of people online, not too realistic ah. Now, such as moving nets, k666 and other large sites of the forum also hundreds of people online, that is generally or 5 minutes to the total number of people, some set to 8 minutes, actually really at the same time online is not so much.
So, if your visit is really large, use our enhanced type of space must be enough. Because we are a dual CPU SCSI hard drive server, handling speed and stability, is not a bit to worry about. Of course, if your site is really up to thousands of people at the same time online, first, we do not believe that this is not possible ah. Because we have not found in the country at the same time there are thousands of people online forum. Speaking of these many people must defy, the mouth is useless, the fact does only represent everything. Second, if it is really achieved, you do not need to ask any space business, your own server bar. Because the space provider will not spend tens of thousands of of servers so that you spend hundreds of of dollars on a server to occupy all the resources. If you encounter, please tell us, we will regularly go to the mental hospital to visit this ancient and modern first person's space business. Because at the outset, this space business is in the bed of a mental hospital with a laptop on the Internet and chat with you for a few hours, and finally was touched by the truth, agreed to this matter.
5. Hundreds of-dollar space and the difference between your own rack server
Too many users think that spending hundreds of yuan to rent space and their own server or similar, in fact, this is not possible, we need to carefully explain.
All young people, we will come to truth. We have a server for what. Very simple, these days to work is not easy, is to make some money to eat. We spend tens of thousands of to buy the dual Xeon server (there are maps on the site), one to put more than 100 users, each user hundreds of yuan. For each user must be strictly restricted in all aspects, rent space you only FTP upload and Web Access rights. The content of the space in order not to affect other users will also be limited by space operators.
Therefore, for many reasons, rent space can only be said to be a personal hobby, not anything can be done. Your own server is really no one to limit you ah.
6. Recently on the Internet unexpectedly see useful four to strong CPU server, too fake, have to say
Recently on the Internet to see that there are four to strong CPU server to do the space, too fake, please if you see immediately turn off, 100% is a bit of technology does not understand the personal website, said no time to run, do not only look at the low price.
Four to strong CPU servers are generally very strict requirements of the banking industry to use the professional server, the price of more than a hundred thousand of, only four to strong CPU now the price must be 8000 yuan. And the size of the server is very large, generally are below with four wheels for the push. I dare say this man has never seen a server like this.
Such high-end server if used to make a space only hundreds of yuan virtual host, everyone calculate is possible? Unless he puts 10,000 users on a single server, do you dare to use it?
Some personal space business to see others with a double to strong server, learn others themselves disorderly write, write also line, first find a understand person ah. I actually see a server that writes P4 four to strong CPUs. Hey, P4 four to strong CPU, the first time heard, P4 is P4, Xeon is the Xeon. Some of the personal space is ignorant to this, it is really let people serve death. I think it is better to write Celeron P4 eight to strong, this is more vicious ah!
Please, if you see any space trader to write something like this four to strong, spit a few off to go elsewhere on the line!
In fact, exposing is also very easy, upload a arjunolic asp probes, easy to see through: Because now the motherboard support Hyper-Threading technology, a CPU can be virtual out of two, that is, if it is like our server with a dual to strong CPU, in the Arjunolic ASP probe will show 4 CPU, if really four to strong CPU, will display eight. I uploaded arjunolic ASP probe to try the server of this brother, but only show a cpu,i took you, the original is a big rotten home machine!
7. Where are our servers?
We have placed the server in the computer room of Netcom and telecom. Because China is not doing well in the interconnection. Generally reflected in you if you use telecommunications broadband Internet upload site to our network on the server, the speed may be slower, but the speed of access generally no problem. Because the south is the world of telecommunications, the North is Netcom's world. But the southern Internet is relatively developed, rent our space more than 90% of the southern users, so our server to put in the main telecommunications room, in the CNC Room as a supplement.
B. Domain Name Class
1. Can the domain name be aligned to a directory in space?
The same results can be achieved in two ways. One is to hide the turn. The second is set on the server side. But the second one is not for us to do. The reason is this:
If you want to go to a directory in space, only a new site corresponds to this directory. The result is that if each user has a few of these requirements, we would have placed 100 sites of servers, into hundreds of sites, and we received only 100 users of the money. Some people who understand the point, use this, buy a space to sell to many people. We come to make money on the internet to eat, not to do good, speaking here, I think we should be able to understand.
But you can do it all by doing the hidden turn. Many users don't like this, and unless you do it by spending a lot of money on space, we can't think of another way to do it.
More than 90% of the users to the lower directory is a few people want to share a hundreds of yuan space, so you do not know how to turn to forget. But some users also take the initiative to find us, revealing whereabouts: network management, I would like to share with friends, to the lower directory, I think the turn is not good, in the server side to me. Well, it is best to give an FTP, done back to me, I now have something, first down!! We can only smile, sharing also let us set up, this is too unreasonable to say.
Oh, it's so blue today!
2. Register the domain name to send 20 level two domain name and support the behind of the pan-resolution
Many people ask this question, but after reading this paragraph, don't ask again. Because now, although the number of registrars at all levels in China, the domain name can be registered finally through the new network, the new network interconnection, China channel, such as several top-level domain names registered, you ask the question, do not have to ask all have you said the function.
Besides these 20 sub domains, now space business generally only to bind a few level two domain name, (if abc.com all only bind www.abc.com and abc.com), even if let you support 200 sub domain name and what use.
Again, the pan-resolution, a server technology can only have a site to support the pan-resolution, the space provider will not give users, if you want to use, only their own rack server. Rent space is impossible to achieve.
Finally want to tell you that the domain name is to support 20 of subdomains and universal resolution, space is not supported, the result is tantamount to not support. If you just rent space, or first look at the space can be bound to several subdomains.
3. Domain name can do hidden turn?
This is to be decided by the Registrar of your domain. But now most registrars support this feature. Just some trouble, to submit the form, by the Registrar after the manual audit can only, the reason is generally afraid to go to the yellow political sites, future accidents, assume responsibility.
4. About Domain name certificate
Many users register their domain name and ask for a registration certificate. There is absolutely no need for a little. Because that's what registrars do themselves, add a so-called official seal, we think, it's just a red circle around it wrote a few red Chinese characters to do a diagram. Careful friends will find that under the certificate, in the most obscure place (eager to write on the back, so that everyone can not see) will be written that this certificate does not have any legal effect, and so on. If their registrars say this to themselves, what do you want him to do, guess your heart: just to comfort yourself!
So you don't have to ask us, we didn't do this red picture! Because the time is long, everyone will find the following words. And we have not found the "This certificate has no legal effect" in the more covert to make people not easy to find places, and so the future technology developed, really can write in the back when we do it.
5. How to set up the Domain name management panel
Many users have a headache for setting up the Domain name management panel, so let's look at the picture below. Click here
6. Has its own DNS to prove that the company has the strength
Often have to understand some friends ask us: You even own DNS are not, not formal AH. This will not be the case if you are very clear. But it doesn't matter, no one is not God to just born "thump" a landing to climb to the computer before the input y63.com to buy our space. Knowledge is a little bit of learning, as explained below.
First of all, a simple explanation of DNS, you register a domain name, login admin panel, generally in the top two DNS, such as ns1.xxx.com and Ns2.xxx.com, the first is the primary DNS, the other is backup DNS. This is the two DNS responsible for resolving your domain name to an IP
In general, each DNS has a minimum of one server, such as the new network or China channel, such as the top registrars, will certainly use a number of server racks of the cluster to ensure that any time can be normal resolution.
But that's the problem. DNS is only a Win2000 server version of a component, it can take a few minutes to install, a penny does not need to spend, so there is no reason to have DNS to prove that the company has the strength. All China has DNS space vendors generally use only one server to do DNS, the second backup DNS are mostly random write a fake. And do DNS this server for money will put another 100-200 users ...
Because you want to understand that space business, space business, is to sell space. This server is selling space to put users, and then by the way of DNS, rather than primarily DNS, by the way put hundreds of users.
If you are a domain name registered in this company, they will certainly use this only one DNS server to do your domain name parsing. If this server is back up or out of place, your domain name will not be accessible. We sometimes encounter users who suddenly come up and say, server problem, quick check, my domain name access to space, we have a check, we send the domain name can be, just this user's domain name can not, this situation 99% is as above said space business own server do DNS resolution, At this point their server must be out of the question or in a reboot!
So if we say that the space providers with DNS are better off not registering domain names with them. To select a company that uses the admin panel of the top-level registrar directly to register the domain name, because that would be much safer.
C. Post Office class
1. Can the Post office have its own domain name suffix?
Many users ask this question and the answer is simple: yes. However, the premise is that you have the domain name, we found that some users only we send the two-level domain name, said our website has written to send a mailbox, why not give. Before there is a user so did not own domain name but to us for a few days mailbox, no matter how we explain also useless, said not to be a liar. We have no way to the last time: we want to send you web@cctv.com, but we have ah, he seems to finally understand what, never asked.
2. Can the Post Office add its own user and free space size?
OK. After you buy our space automatically assign a mailbox administrator webmaster, with this user to enter after you will be free to do what you want to do.
3. Buy space to send users back to hundreds of M post office
Many users buy space after very concerned about the size of the post office, Ah, we do not think it is too much necessary. Because even if you send 300M Post office, you can write letters are generally written in Chinese, are some text things, even 0.1M are not used.
Now everyone understands that your problem is only to comfort yourself. We do not know that other space chambers will not put these words out, we just want to let users understand what is actually going on. Because we found that more than 90% of the users asked the question, the final answer to the reverse and their own thinking exactly the opposite. So we built our friends to take a good look at our FAQ. You will learn a lot of things.
D.ftp class
1.FTP can not log the reason
Many users ftp not even say we have a problem with the server, in fact, just change the FTP client software settings on it, we found that more than 95% of users do not know, the following we explain.
FTP has both active and passive transmission mode, server-side two ways are supported, the problem is in the user's use of the client, now many FTP client software (such as CUTEFTP/FLASHFXP) after installation by default only support a way, Can now many broadband access is no public network IP LAN and ADSL or install a firewall, it is not connected to the server, in fact, as long as the change to another mode of transmission can be, but now most of the FTP software version is updated quickly, each version of the settings are not the same, We also cannot have the time each version each user tells how to set up, therefore we recommend everybody uses the LEAPFTP, it has a very huge benefit, is simultaneously supports two kinds of transmission way to connect the server alternately, no matter how all can connect. We have not found any other FTP software to this function. Related software can be found at our download station.
2. Why the FTP upload speed is very slow
First of all, our servers are placed directly in the main network of the engine room, we have no problem here. We also found that most users upload speed of about dozens of K, and there are only a few individual users K, this can not avoid the fact. The reasons are not so clear.
China's wide range of providers have mainly North Netcom, Southern Telecom, Unicom, railcom and other companies. The interconnectivity between them has been bad for China's current situation. If you use a telecommunication ADSL network, the connection is placed on the Unicom server. Access is generally no problem, upload may be slow. Because even if the two exports are big, such as each is on the hundred G, can they interconnect the export if only 10M, the entire Chinese users at night after dinner idle all to the Internet, sharing the poor 10M, the speed imaginable. Of course, here's just an example. is to say that many times is China's major service providers interconnected to do a bad job caused some problems. and generally mainly reflected in the use of FTP upload, this space is fast, that space is slow. But this is not a server issue.
Of course, sometimes it is the user's own problem. Is that when users surf the Internet, the broadband provider rents the export itself very very little. An example of a personal experience.
When I was in Beijing, I lived in the building and a few buildings around by a company made the so-called "fiber to the floor, twisted to the door." The line has been to the door, but also say what Ah, apply for a bar. It was a good start, but later it was known because there were fewer users. Of course, the day later is slower than the day, sometimes not one day. Later asked them network management (anyway is a part-time job, and I told the Truth), their company just rented 2M of telecom export, let these several buildings more than 100 users in use, and have not know still pay money, this company is to give money to open, who does not like money ah. The promised service is, of course, to say later. Rob money to kill the law, can be false promise to tell lies did not hear who was caught. Now the application of ADSL to a user 2M, it is too exaggerated.
We are now doing a virtual host, if just to catch up with this broadband users buy our space, is to give us 10 wings, the Buddha invited to come together to give him to blow fairy gas can not make him fast ah. Of course, he must also scold: XXX, what broken server ah, so slow, I want to sue you ...
And this phenomenon is not individual, because the southern Internet industry relatively developed. Bandwidth resources are very nervous, said that is very expensive, many service providers here to rent a small number of exports, there is an unlimited expansion of users. The results are conceivable. I think a lot of friends on the Internet see "x width is not wide, not to solve the problem" Beijing to the south of the users are very dissatisfied. On the Internet by the national exposure. I think so big company all this kind of service, small and medium broadband service provider is not to think of!!
Now the general use of ADSL users in China are also good, no matter how it is given to the 521K-2M exclusive Ah, will not be affected by others. But there is a problem that will be affected by interconnectivity. Simply put, is the broadband business to give you a 100M exclusive, nor even where the fast, this is a lot of people in the minds of the misunderstanding. Unless the world's servers are all around your house, you will not be able to play it slowly.
Speaking of this, some people may think so, I use is the telecommunication ADSL, I rent the space to put in the telecommunication server, this if did not have the accident, you are certainly not slow. But you do the site is for the people of the country to see, not to see for themselves ah. Ah, other people do not have to use the letter, what way to access the Internet. A friend will ask, how to do it. Answer: No way, because now China interconnection interoperability itself is not good, so this problem you do not have to think, because you can not be a person to solve. This requires major ISPs to spend money together to increase exports. I think if they come together and say, "for all the Chinese netizens, we spend money together to increase the interconnection." Can you believe it? I don't think all the Chinese netizens will believe it. If they are gathered together to study how to cheat Internet users more money, I think we will definitely pass.
There are no more examples, many users in Internet cafes, and now many internet cafes to save money, the rental of the export will not be very large, internet cafes generally have dozens of hundred machines. Everyone is surfing the internet or playing online games, bandwidth consumption is very serious. To a large extent, this internet café exports low cause upload slow ah.
Say one more reason. Now many users use ADSL, it's the principle of creating it is not very stable. Your ADSL and the data Bureau within 5 kilometers of speed and stability is guaranteed. And the aging of the telephone line, near the home with high-pressure equipment, a large car through the strong magnetic field, etc. may cause ADSL disconnection. About 30 seconds or so, there are many users suddenly asked us not on the server network, quickly check the server. But after a while he said, "All right." Ah, it is possible that ADSL in the heavy connection. But we can not say, because no one is willing to admit that they have problems. If we say two more words. Many users will talk to you for one hours to a few hours. If we do not return, we will say that the service is not good. Hey.
So your site well after the people in the country visit, there must be a slow, not your users have access to slow said it is our server problem ah.
We do not mean that our server will not be a problem, because it is to put the main network room, is the possibility of a small problem. If there is a problem, the phone will be crazy, QQ crazy Flash. We now know that there is a problem with the server. We'll take care of it right away and let the server recover at the fastest speed. But if the phone does not ring, QQ also no one asked. We're still working on it. At this time QQ has a strong person up on the crazy hair: Server problem, quick check, quick check. We have no answer, because now he can't, we believe, but his problem, but said it is our problem, we do not have time to waste time here.
E. Other
1. Magical Arjunolic ASP probe
Now many friends use Arjunolic ASP probes to test the speed of space, all only see the bottom of the integer and floating-point calculation time, as long as the smallest, think this space is the fastest and best. We consider this approach very undesirable. Because most of the space vendors put the fastest server to let you test, and each space quotient of data in the gap between hundreds of is normal, because that is the unit of millisecond level. For example, a space commercial a very bad home machine a user does not let everyone test, the other space is a dual-CPU real server can be above already has dozens of users. You will be glad to think that the rotten machine is fast and stable after you have been tested for almost milliseconds. Actually, it's just the opposite of what you think.
In fact, using Arjunolic ASP probes can test more useful data, let you see the space quotient and the content of the site is not attached to the lies.
First look at the server IP. If the beginning of the 192.168 and so on, is generally done by the port should be shot, mostly in the home ADSL and other broadband use their own home machine to do the so-called server. The characteristic is the price is low, do six months to run.
Look at the number of CPUs again. Today's motherboards support hyper-Threading technology, which can virtual two of a CPU. That means you use an ASP probe to measure 2, in fact, may be 1 CPU. And we use the dual Xeon server, with the ASP probe measured is 4, the actual is 2.
Look at the server disk information again. What we want everyone to see is not the speed test of the hard drive. is the number of partitions and the size of the hard disk to see whether it is a SCSI hard disk or an IDE hard disk. Now the mainstream SCSI hard disk is the 36g,ide hard disk is 80G, if the latter, the general majority of the habit is divided into c/d/e/f, such as multiple partitions, if the former, generally only divided into C/D two. Now generally each partition is set to administrator permissions, so the general Arjunolic probe does not show the size of the hard disk, if you can, 80G that 99% is the IDE hard disk.
The meaning of 2.CPU occupancy rate
Simply put, the program running in space consumes CPU resources, and we limit the maximum CPU usage on the server side. Has the user asked the enhancement type one user to give 4%, 100 users not to be 400%? Ah, we put a server to more than 100 users when the CPU occupied only 20-30% or so. That's not what you think. It's just an argument, don't put it all on the stand.
3. How often does the server restart
We are using a dual-CPU real server, very stable, generally not a few times within 1 months. But there is no net that doesn't matter, this is the fact that everybody knows. If you encounter a user who is using a large amount of resources to influence another user, it will take us about 30 seconds to restart IIS, as is the case with a significant problem that takes a few minutes to reboot the server.
Many use the server, because a large number of concurrent data can not be processed in time, is often CPU occupied 100% and need to frequently restart, the user is also complaining constantly, so we must be careful to choose the right space business.
4. The difference between Xeon and ordinary P4 CPU
The Xeon CPU is dedicated to the real server board and is easily handled when concurrent requests are received from thousands of databases in a virtual host environment. And ordinary P4 often because processing does not come over the CPU occupy frequently 100% and need to restart, because that must be the household level thing.
The difference between 5.IDE and SCSI hard drives
IDE hard drives are far less than the server-specific SCSI hard drives in terms of RPM and transmission speed. and IDE hard disk is the biggest disadvantage is in the read and write operations are a large number of CPU resources, the simplest example, everyone's own machine is the IDE, in the replication of data, CPU consumption generally more than 60-70%. It would be slow to do something else at the same time. Do you think, if you do a virtual host, more than 100 users at the same time read and write, how fast? The SCSI hard drive is different because it has its own "processor", which, when read and write a large amount of data, is processed by its own processor, consuming less CPU resources and allowing the CPU more time to process thousands of data requests.
6. What is the real ICP card
We found that some users are said to have ICP Card company cheated, we look, originally only in the site delegated a ICP card map, click to enter just a company's business license. This is not the ICP card at all.
Then what is the real ICP Card, simply said, like the one below our site, click to enter a company and server location of the introduction, the following is the website of the Trade and Industry Bureau. If not, enter the website of the Trade and Industry Bureau to find or directly to the trade and Industry Bureau to verify the telephone.
7.CGI and PHP than ASP security error
The CGI and PHP source code all need to install the setup to use correctly, need the real sensible to be able to do. And many users do not install the success of the server that we do not support, even if successful, but also because it will not set a lot of problems, but not safe. We actually found that the ASP is running much faster than them, and just upload it to work.
We want to tell you that it is not safe to set up. If not very understand, or use ASP bar.
8. The server put in Beijing and Shanghai and so on the speed really fast?
First of all, our analysis represents only a personal point of view. Always listen to understand that Beijing Shanghai Guangzhou and other big cities such as network bandwidth and the major ISP connections between the export of sufficient, this who do not want to deny, after all, China is now the most developed cities. So many people have travelled all the distances to bring the servers to these places for hosting. We've thought about it, but what's the truth? Tell us about our experience and everyone knows it.
We let go of Shanghai first, and then the big slow, because I heard that all the people in China to do online movies and downloads to Shanghai hosting server, and the provider is to put the money, a 100M put more than 100 servers. Later our server because of the speed too slow in the can be said to be unable to use the state, only a refund. The provider deducted half of the money for a variety of reasons at the time of the refund. Later, I heard that the reorganization of Shanghai, more than before the stronger.
And then in Beijing, because I heard that Beijing also Zhuang room 40G export, the provider said they rented 200M export, unlimited flow, we hand over money to the room, a look, the room is very formal, they rent is also 200M, can 200M put nearly 200 servers! As some personal space business said: Our space 100M only 50 yuan ah (but I do six months on the run).
Beijing is also the beginning of good, then the giant slow, the user scold us, we find Beijing, they say that other servers are normal, is our server traffic too much problem, vomit, and retreat, of course, and was deducted the money, we put that server in Sichuan House Hotline Room, fast, we only now understand, The reason is not that we have problems, a group of black-hearted custodian.
