Web Servers
A web server is a computer system which specializes is delivering specific content, such as a web page or a set of files, over the internet. Questions about various specific web servers and how to setup and maintain them belong here.
406 Questions
What does unable to connect to the remote server mean?
It means that the server you are trying to communicate with is not responding to requests, for a multitude of reasons.
What protocol is used to transfer a file from a web server to a web browser?
The protocol for all web transactions is Hypertext Protocol..HTTP
How do you configure localhost?
Localhost is always IP address 127.0.0.1. This is also known as the loopback address because every machine uses this same address to refer to itself. You do not have to do anything special to set this up. That is; you do not require a DNS (domain name server) to resolve the localhost name to IP address 127.0.0.1 because it is "hard-wired".
If you have a local webserver running, entering "localhost" or "127.0.0.1" in your browser will bring up the default page for that server. Other machine's on your network can also access your local webserver, but they must use your machine's local area address or the machine name to access it (if they use localhost they'll simply refer to themselves). If you do not have a webserver running, your browser will simply tell you that the web page is not available. Setting up a webserver is simply a matter of installing one. Consult the webserver documentation for information on configuring it.
What is the difference between content filtering and URL filtering?
A URL filter uses a URL database with verified domains to block domains while a content filter guesses the nature of each page of each web site "on the fly" URL scanning web pages for words.
How do you configure a web server to use a different port number?
The answer to this question depends entirely on the web server software you are using. Generally, however, there is a configuration setting that controls the port number. Check the manual or configuration files for the exact place to change the port number.
What network protocol reports on the success or failure of data delivery?
TCP http://en.wikipedia.org/wiki/Transmission_Control_Protocol
What is internet DOS commands?
*help
This command gives you a key to virtually everything you need to use DOS effectively. Can't remember the format for the FORMAT command? Not a problem! Type HELP FORMAT and press the ENTER key, and you've got everything you need to use FORMAT! This is true for virtually every DOS command so if you remember HELP command name you won't have any problems.
Another way to get help (or, if you don't install the HELP files suggest above, the ONLY way to get help in Windows 95) is to use /? (slash, question mark) after any command. This is faster and sometimes a more useful form of help, but it is generally only a listing of options. HELP is usually a more verbose help facility than /? is.
*copy
Once you know where to get help, the rest is easy. The whole purpose of DOS is to let you get around the directory tree easily. You use DOS to start applications (like my own P11.EXE program) and to copy files, delete files, build places to put files, and compare files, and so on. Files, Files, Files. That's what DOS is really for.
The #1 tool for file handling is the COPY command. Specify the "from" file first, then the "to" file. COPY only copies from within one directory at a time, but the "to" directory can be different. For copying entire directory structures, use XCOPY instead.
What makes COPY so powerful is that you can use "wild cards" like * and ? within the file name.
*xcopy
Like COPY, XCOPY can use wildcards to copy a file or group of files to another directory. But XCOPY is more powerful because it has the ability to copy an entire directory structure in one command. Use the /s option to accomplish this. Use HELP XCOPY to learn more, of course!
*cd
CD is the cold, hard way of doing things, but sometimes it's the right way. What makes it cold and hard is that in comparison to Norton's Change Directory (normally abbreviated NCD, but I abbreviated it to C on my system), the DOS CD command requires you to type the complete directory entry, all the way back to the root level! This is absurd. NCD, on the other hand, lets you type in anything that's close, and it will search your entire directory structure and plop you down right where you want to be. For example, to go to the \p11\pumps\svgapump directory, I can just type in: c svgap and immediately NCD will take me there. With CD, I would have to type cd \p11\pumps\svgapump to accomplish the same thing. Saving keystrokes is the name of the game. (That's why later in this tutorial, you'll learn to write batch files.)

Is a Windows server better than a Linux server for the web?
In my personal opinion, No, a Linux server is the better answer for the web. I would recommend a windows server only when running asp/.net, and with the introduction of mono (an apache module), Linux machines can run .net (although I've never used this, myself, and it is in its infancy).
Linux, in general, has much better thread and memory handling than Windows. In a multi-threaded web server, it should serve you better.
Remember, that things like this are always a personal preference type of thing, and the debate between Windows and Linux is fierce. My advice would be to look up benchmarking information for Windows web servers and Linux web servers, and see which would suit your needs.
Which device you connect with the help of straight cable?
Straight through cables can be used to connect devices together via switches, hubs, routers, bridges.
When was the first web server built?
In 1990. By Tim Berners-Lee, at CERN (European Nuclear Research Center).
What are types of web technologies?
Web technologies related to the interface between web servers and their clients.
So there are a large number of interfaces available these days. A few of them are:
CGI
Perl
PHP
Jquery & AJAX
Struts2 (MVC 2 Arch.)
JSP
ASP
ASPX
and various others...
Since IP is an unreliable, Best-effort Protocol, it is unaware of the quality of job it is performing. IP packets are sent without certainty that they will be received. The IP protocol makes a best-effort to deliver packets, but it has no way of determining whether the packets are delivered successfully or whether they are lost en route. IP has no way to inform the sender of reliability problems. Thus, TCP can be relied on to inform the sender of delivery problems.
Is the apache web server easy to use?
I can not answer this about the Windows version of Apache but if you use any version of Linux or UNIX it is real easy to set up. I t normally takes about 15 to 30 minutes for a newbie to set up Apache as a web server. There are literally hundreds of articles and videos on the web to help set up Apache. Many of the Linux distros has Apache as a part of their Linux Packages. All of the Linux distros has Apache in their repositories available for download.
t depends on whether or not you are fluent in UNIX, most people are not these days since it is more kin to windows DOS than Vista or 7. If you are not and wondering what the world UNIX is then it is not going to be easy to use.
Do you think Linux will surpass other operating systems for network and web servers?
Linux has already surpassed all other operating systems for web servers. The growth rate for new servers is slowing, but it is still ahead of Windows servers.

What is sub net mask within the TCPIP configuration is used to distinguish?
The subnet mask within the TCP/IP configuration is used to distinguish the ? from the host address.
Why does omegle say Connecting to Server and wont let you video chat on it?
You do not have a flash player
I have heard that hey0 is great server software. I know of a lot of servers run by it. There is also a YouTub tutorial for using it (See Related Links for download and tutorial).
I don't remember if its juts a plug-in or what, but it works. I made a server awhile ago but my router wont allow port forwarding.
-----------------------------------------------------------------
Well hay0 have been discontinued, if you want a proberserver app
with a great plugin system, you want bukkit just google "Minecraft bukkit server"
Where is world's main server and how much storage does it have?
The world does not have a centralised, main server, but rather, a group of them. ICANN, a California-based not-for-profit institute, is responsible for all IP addresses in the world, and its servers can be called the world's "main" ones.
How do you test a web server using telnet?
1. Open up a command shell
2. Enter telnet
3. When it says it is connected, enter GET HTTP/1.1
4. The prompt should spit out some HTML code, indicating that the web server is responding and sending web pages (if only an error page).
