IRC - hosting encyclopedia. IRC service and network etiquette

Through the use of various network protocols, the Internet can ensure the execution of two basic functions:

· Being a means of communication between remote users;

· Being a common accessory information resourcesposted on the Internet.

Obviously, each of these functions can be implemented using various means, which provides a variety of services provided to Internet users. Tools for the provision of specific services for users of the global network is customary to be called Internet services. At the same time, communication services provide communication between remote users, and informational - enable users to gain access to certain information resources stored on the Internet.

Communication services

Obviously, there can be only two communication modes on the network: direct communication mode in real time, when users during communication are interconnected. Analogue of such communication is a conversation on the phone. Sometimes it uses the term on-line to designate such a mode. Another mode is the deferred communication mode (OFF-Line). An example of such communication in everyday life is sending a letter or telegram.

Direct communication on the Internet

Direct Communication Forums - IRC (Internet Relay Chat)

This system allows Internet and Intranet users to talk in real time. To get this service, users must unite into channels supporting various discussion topics. Any characters entered through the IRC program appear on the screens of all other participants in your channel. IRC use technology has a lot in common with work in UseNet conferences. But if there is communication going on in deferred mode, there may be a live conversation here. The peculiarity of this communication is that the message text is entered using the keyboard, and then falls on the overall display. Thus, when using this service, communication between participants occurs in on-line mode in writing. Like teleconferences, the participants of the Chat conference are divided into thematic groups.

Currently communication in " chat"Used as a kind of game in which each participant usually comes up with some" image "for itself and beats it. Between the participants of the Chat, it is not customary to emerge for real communication. However, the Chat service can also be used for serious communication - both collective and personal. One of the popular programs that provide work in this mode is ICQ. In November 1996, the first version of ICQ (I Seek You, i.e. "I'm looking for you") was launched on the Internet and has been spreading avalanche-like. It can be downloaded for free on this site: http://www.mirabilis.com. After installing the program, it will automatically boot when connected to the Internet.

Internet telephony

This service provides the possibility of voice communication via the network in ON-LINE mode. This is a new, developing service. Its main advantage over the phone is low price. Internet telephony quality is currently inferior telephone communication (delays in time, sound distortion), but over time these shortcomings are gradually overcome.

The general principle of the IP telephony telephone servers is: on the one hand, the server is associated with telephone lines and can connect to any telephone world. On the other hand, the server is associated with the Internet and can contact any computer in the world. The server receives a standard telephone, digitizes it (if it is not original), compresses, splits on packets and sends over the Internet for a destination using the Internet protocol (TCP / IP). For packages coming from the network to the telephone server and go through telephone lineThe operation occurs in the reverse order.

IP-telephony technology combines channel switches (transmitting voice information) and packet switching networks (transmitting data) to a single communication network. Uninterrupted voice recognition and its transfer from one network to another are solved using various gateways. As shown in Fig. 1, the gateway is a device in which telephone lines are turned on on the one hand, and on the other hand, the IP network.

Fig. 1. IP telephony functioning scheme

Voice like analog fluctuations in the IP telephony system exists only in phone tube. On the rest of the transmission channel from the subscriber to the subscriber, the speech is digitized and transmitted as IP packets. Packages coming to the nearest to another subscriber gateway are converted back to analog view (voice signal) and enroll in the telephone line. Most wide use In practice, received skype (Skype pronounced) - free programproviding encrypted voice communication via the Internet between computers (VoIP) as well paid services To communicate with the subscribers of the usual telephone network. You can download the program from the site at http://www.skype.com/intl/en/home.

Telnet service

This service provides interaction with remote computer. It allows you to turn the user's computer to a remote terminal of another computer. therefore this service also called E. muya remote terminal. The terminal from the ordinary computer is characterized by the fact that it does not perform its own calculations. All that is entered on the keyboard of the workstation is transmitted to the remote computer, and the results obtained are transmitted back and are displayed on the workstation monitor. As remote computers, mainly used machines running operating system UNIX [Unix]. Therefore, knowledge is required to work in the remote terminal mode. major teams This operating system. With the development of graphic operating systems, such as Windows, the command mode of operation has become less popular, and telnet service in lately Most users do not apply. Many information systems previously available exclusively with TelnetToday is available from the World Wide Web, which will be discussed below.

By establishing communication with TelnetThe user gets the opportunity to work with a remote computer, like with "your", i.e. Theoretically, get all the resources at your disposal if access is allowed. Remons Telnet Provides open accessBut the organization of interaction is fully determined by a remote computer. Two types of Internet services require connecting to servers through Telnet: Library catalogs and electronic ads (BBS).

Working with a remote system can be conducted in the "transparent" mode when programs on the server and the client only provide a connection protocol, and in the command when the client receives at its disposal a set of server commands. It should be noted that due to safety reasons, the trend of reducing the number of Internet nodes will be used to use Telnet To connect to them.

Delayed internet

Email - E-Mail

This is the oldest and one of the most popular network services. Its purpose is to support email messages between users. In its essence, email is a system of exchanging electronic messages In computer networks (in delayed communication -OFFLine mode). Scheme of work email Reflected in fig. 2. The mail server is a kind of post office where the incoming and outgoing correspondence of users registered on it. This correspondence is placed in "mailboxes" of users - specially designated hard disk partitions. Each user receives a personal mailing address for which letters will flow to it. It should be noted that email addresses are somewhat different from other Internet addresses, but very similar. They consist of two parts separated by the @ symbol. To the right of the symbol is located the Internet address of the computer on which the post office of the subscriber is located. This address is formed in the same way as any other domain name in the Internet. To the left of the symbol @ there is a subscriber name. An example of a postal address can be: [Email Protected]

Fig. 2. Email operation scheme

In order for this service to become an accessible to the user, a number of procedures must be performed. First, the user must register on the mail server. At the same time, the email client address and password is recorded - a set of characters that allows you to identify the user. Password provides confidentiality of this service. A registered user has the ability to write text text, specifying the recipient's address. To do this, the Email Client-program includes a letter preparation editor. Prepared letters are placed in the "Outgoing" folder. The server receives all the letters from the Outgoing folder and, in addition, transfers the received letters that are placed in the "Inbox" folder. The user connection with the mail server is necessary only for sending a letter and delivery to the user's computer from the Inbox folder. The mail server works constantly. It periodically browsing "mailboxes" and organizes transmission over the network of outgoing letters. Incoming correspondence mail server decides on "boxes".

An email client-program except the reception function of letters during a communication session can still be made by many more service functions:

· Preparation and editing letters,

· Organization of address book,

· View mail archive,

· Sort and remove letters from the mail archive, etc.

The popular client e-mail is the program Outlook Express.Included in the standard delivery of the MS Windows operating system.

The server and email client work on different protocols. Server POP3 program (Post Office Protocol - Post Office Protocol) In addition to all other things, the function of information protection. During the communication session, it establishes the identity of the user, provides communication with its personal drawer. When working client-program, no identification is required. Her task is to transfer outgoing letters to the server and accept received. It uses a simpler protocol SMTP (Simple Mail Transfer Protocol - the simplest mail transfer protocol).

Teleconferencing service

Teleconference is an electronic messaging system on a specific topic between network subscribers (in deferred communication mode -OFFLINE). Each participant receives all materials to its email address (E: Mail). Each emission of the subscriber is published on the teleconference server and comes to all participants. (Fig.3).

Fig. 3. Teleconference functioning scheme

Unlike email, when the user sends his letter to a personally to someone subscriber or a group of subscribers, a letter to the teleconferences is sent to all its participants simultaneously. In turn, all messages that enter the conference will enter the user's mailbox and boot into its computer during the communication session. To become a member of the teleconference, it must be subscribed to it. For these purposes there are certain addresses. Any conference is dedicated to a certain topic, so the correspondence in it occurs only within the framework of the topic. According to some data, the number of current conferences on the Internet exceeded 500,000.

Teleconference service is called differently: newsgroups, UseNet service. On the network nodes, teleconference serves the news servers. On the user's PC, the news client must be installed. The MS Outlook Express program mentioned above is simultaneously postal client and news client.

Teleconferences combine both communication and information functions. On the one hand, personal communication takes place here, on the other, the conference materials contain a large volume. useful informationthat a certain time Stored on the server. This information can be considered as some information resource (electronic newspaper). This is especially important for professionals participating in professional topics: science, manufacturing, business, trade, etc. In the conference materials, you can find valuable advice, advice that will help in making important decisions.

Information services

Information services provide users with access to certain information resources stored on the Internet. Such resources are either files in one of the generally accepted formats or various documents. Using these resources is provided with the help of relevant services.

File transfer service

Often this service is called the name of the protocol used: FTP (File Transfer Protocol - file transfer protocol). On the part of the network, the service is provided by the so-called FTP servers, and from user parties - FTP clients. Assigning an FTP server is to store the set of files of the most diverse purpose (usually archived). Most often it is program files: system and applied software. But in the sets, files and any other formats can be stored: graphic, sound, MS Word documents, MS Excel, etc. All this information forms a hierarchical structure of folders (directories and subdirectories).

After connecting the FTP client with the server on the user's screen, the folder storage file interface and files on the server opens (like Windows Explorer). Next, work happens just like with file system On PC: Folders and files can be viewed, sorted, copy to your discs. Client FTP. part of the program Internet Explorer. And therefore always available on a PC running MS Windows.

File sharing

The file sharing is called a service providing the user a place to store its files and round the clock access to them via Web, as a rule via HTTP (and possible by FTP). Such a service allows you to conveniently "change" by files.

On the central file sharing page, the user loads the file to the file sharing server, and the file sharing gives the user a permanent link, which it can send by e-mail, publish blogs, on the forums or forward via instant messaging (ICQ, MailAgent, IM, etc. .).

WORLD WIDE WEB (WWW)

Www. - It is distributed information system with hypersdias that exists on the technical base of the World computer network Internet. This information system is a network of documents related to the hyperlinks. Such documents are called hypertext. Since links may indicate any document on the Internet anywhere in the globe, this system And named worldwide web.

The smallest information unit Www. is an Web.- A page that is a set of text, graphic and multimedia files connected by hyperlinks. Group Web pages belonging to one owner and interconnected in content are constituted Web site. Host - Computer for Storage Web pages and Web. - sites called Web server. Client program designed to view Web sites, called a browser (from the English Browse - view, scroll).

Browser (from English Web Browser; option Browser - Outdated form) - software To view websites, i.e., to request web pages (mostly from the network), their processing, output and transition from one page to another.

Most browsers can also show the table of contents of FTP servers.

Browsers were constantly evolving since the birth of the World Wide Web and with its growth became increasingly popular programs. Now the browser is a comprehensive application for processing and outputing different components of a web page and to provide an interface between the website and its visitor. Almost all popular browsers are distributed free or "included" with other applications: Internet Explorer (together with Microsoft Windows.), Mozilla Firefox (free, free software, compatible with some distributions Linux, such as Ubuntu), Safari (together with Mac OS X and free for Microsoft Windows), Google Chrome. (free of charge) Opera (free from version 8.50).

Electronic media

Electronic tools mass media (Media) - a convenient means of obtaining operational information. Almost all modern newspapers, magazines, radio stations, tV channels (Russian and foreign) have their own websites on the Internet, which can be found with the news, listen and see informational messages (in real time including). On the website www.karta-smi.ru you can find links to Russian electronic media.

The electronic version of the newspaper makes it possible not only to read the fresh release, write and send a review of the review about read, but also to access the hearing of old newspaper issues. On the sites of TV channels, you can view news and television programs, participate in on-line conferences and forums, discuss seen, express your opinion. On the Sites of Radio Station, you can listen to news and radio programs in ON-LINE mode.

Comprehensive Internet services

The introduction of the Internet into practical activity has led to the emergence of new services that unite both communication and information capabilities of the global network. These include:

ON-LINE translators and dictionaries

Using on-line translators and dictionaries on the Internet, you can translate texts from the Russian language into English and vice versa.

So you can translate texts e-mail, content of sites, etc.

Online shops

You can choose a variety of products in online stores, and the selected goods will be delivered to you home. Thus, curriculum and fiction literature can be acquired, for example, CDs. As a rule, such purchases are cheaper than in ordinary stores.

Electronic payment systems

Electronic payment systems allow you to pay a wide range of services, in particular, to produce utility payments. The scheme on which the electronic payment systems work is extremely simple for the user. By registering in the system, you automatically open your account. By enrolling it in a convenient way to you, the desired amount of money, you can use it for calculations with partners of this system.

Payment systems received the most widespread in Russia:

· QIWI, currency - Russian rubles

· Yandex.Money, currency - Russian rubles

· Webmoney, currency - Russian rubles, euros, US dollar, hryvnia, etc.

Use these systems simply. For example, in order to safely and quickly pay for goods and housing and communal services on the Internet, you can use the Yandex system. Money. To do this, go to the Yandex.Money site or Money.yandex.ru, register and start an electronic account.

IRC Basics

Internet Relay Chat. It may be for you one of the most useful and attractive Internet services. This system gives us The ability to talk to people from around the world to a wide variety of topics. Initially, the IRC was created to communicate between people and to provide a little fun. But before you deepen in a detailed discussion of how IRC works, you need to know how it all starts and who the main IRC users began.

What is the goal of IRC.

IRC is mainly used as a free time communication system. It allows you to communicate with people from around the world for thousands of various topics. Because of its interactive nature of the conversation in the IRC, much more chaotic than an alternate exchange of views in USENET teleconferences.

Many IRC college students replace intercity telephone conversations, because using the Internet you can use IRC for free. There are no restrictions on the number of people participating in IRC, nor on the topics discussed at the same time.

Some organizations from the field of education and entertainment periodically conduct online meetings. There are groups of writers, philosophers and even actors who perform on IRC. Some commercial organizations use the benefits of IRC when conducting distributed meetings. However, as for other types of communications in the Internet, the information transmitted is not protected, and some companies prefer the use of more reliable funds in this regard.

IRC Development History

The IRC system was developed in the late eighties of the Finnish student who had engaged in the problem of improving the quality of interactive information exchange with its electronic board. In the end, the project has shifted from private BBS to the Internet application. Early versions IRC allowed only the simplest forms of communication between users. Time went, new opportunities were added to the system, and its work was improved. Today IRC provides many exciting opportunities, this system is programmable and allows you to communicate with people around the world.

Internet Relay Chat grew along with the Internet. The intensity of the work of hundreds of Channels IRC has increased colossal over the past few years. Previously, you would need a workstation with the UNIX operating system, since the Internet roots in the UNIX system. But in recent years there has been a significant amount of software for personal computers such as PC and Macintosh, allowing you to connect to the IRC.

To connect to the IRC, you need any connection to the Internet. The quality of work in the IRC depends on the quality of your connection to the Internet.

How does it workInternetRelayChat.

Internet Relay Chat works based on TCP / IP protocols that are basic for the Internet. The IRC system includes two main TCP / IP network components - client and server. In this case, you directly communicate with the client part.

IRC clients

The term "client" is just a common name of the software you need to have on personal Computer To connect to IRC. The client program allows you to connect to the IRC server serving at the same time many other connections. IRC servers located at different points of the Internet are interconnected; Thus, from any IRC server, you can access all conferences and users of any other IRC server.

The options for setting the IRC session parameters depend on the client program that you use. In the next chapter, you will get acquainted with two IRC clients for Microsoft Windows. In any case, your IRC perception significantly depends on the client program used. The best customers are very flexible and at the same time easy to use, others limit you to use some features available on the IRC server.

Basics of e-business (e-business)

1. Basics of the global Internet of the Internet

1.2. The basic concepts of service of instant messages and messengers

The messaging system is one of the most affordable and demanded means of communicating on the Internet, in corporate and local networks. Messaging services are divided into messaging services in the Offline mode (E-Mail Post Systems) and Instant Messaging Services (Internet Relay Chat and Instant Messaging Service) online.

Messaging systems have their own communication networks, most of which are built by the Client Server architecture.

Offline messaging services

Messaging In Offline mode, the interaction of two programs is the mail server and postal client. To work with e-mail, you can use both mail clients and email web interfaces that are located on email servers. Using the web interface, you can work with mail directly on email web servers.

WWW-based postal systems allow you to handle postal messages on the Internet using a conventional browser, not postal program. They work according to the "2 in 1" principle, combining the features of the mail server and postal client.

Message exchange services online

IRC service

IRC (Internet Relay Chat or Chat) is the first tool for online communication. big choice channels (topics) for discussions with like-minded people. Chat is a real-time text dialogue.

This service is based on the client-server network architecture, so it is necessary to install a client application for online communication on the Internet (IRC-client). When you start the program - the client, it establishes a connection to the selected IRC server. Since the IRC network servers are combined with each other, it is enough to connect to one of its servers to communicate. When connected to the IRC server, the user sees a list of available topics (channels) in which it can communicate.

Initially, the IRC service had one IRC network, which was subsequently divided into several IRC networks. These IRC networks are not associated with each other and have their own names (Dalnet, IrCnet, Undernet, RusNet, Wenet, IrCnet.ru, etc.). Inside each IRC network exists their thematic areas or channels. On the Internet you can download IRC clients for UNIX-like OS, OS / 2, Windows Systems and mobile phones.

To communicate in the chat, you can use both IRC clients and Web chats. Web chats are designed to exchange messages on the server (web page) using the browser, in this case, install the client application is not required on the PC. Web chat is a web page where you can communicate with other visitors in real time.

INSTANT MESSAGING SERVICE

The Instant Messaging Service, IMS) has become the result of the chat development (Instant Messaging Service). IMS is one of the technologies that provides communications in Internet networks. In instant messages, except text messages can be transmitted, sound signals, pictures, videos, files.

This service has its own networks. The IMS network architecture is built according to the client-server principle. The IMS client program that is designed to conduct a conversation and instant messaging online through instant messaging services, is called a messenger (Instant Messengers, IM).

As a rule, the exchange network has a separate server (some networks are decentralized), to which messengers are connected, and their interaction protocols. Most instant messaging networks use closed or proprietary protocols (own protocols belonging to only one network) information exchange. Basically, each such networks uses its messenger.

There are usually missing interconnections between various IMS networks, therefore the messenger of one network, for example, ICQ cannot contact the messenger skype networks. This means that users must register for communications among themselves among themselves and install their messengers.

But there are alternative messengers for instant messaging services that can simultaneously work in several networks. For example, a free open multiprotocol modular client (messenger) Miranda Im (or Trillian, Pidgin) allows you to connect simultaneously to several networks, which eliminates the need to install a separate messenger for each network.

In addition, as an alternative to proprietary protocols for IM, an open jabber protocol (Jabber is a family of protocols and technologies) or XMPP used in many messengers (Jabber clients: PSI, Miranda Im, Tkabber, Jajc, Pandion and others). Jabber (chatter, trit) - instant messaging system and presence between any two Internet subscribers based on the XMPP open protocol that uses XML format. This is a new generation communication system.

The network does not exist a single central server, Jabber is decentralized (with decentralized servers) expandable and open system. Everyone can open their instant messaging server, register users on it and interact with other Jabber servers. Jabber is used to organize communication on the Internet, local and corporate networks.

Modern messengers provide users with many useful features, such as IP telephony, video chat, indication of network status of users, etc. To communicate in the instant messaging service, you can use both desktop IM client (messenger) and client web version (for example, Google Talk Gadget, Jwchat, Meebo, MDC, etc.).

List of basic functions that can provide modern instant messaging messengers:

• chat (video chat, text and voice);
• VoIP Services: Calls to a computer, calls to stationary and mobile phones;
• the possibility of sending SMS;
• file transfer;
• tools for working in real time;
• the ability to communicate in the chat directly on the web page;
• reminders and alerts;
• storage of communication history for each contact;
• indication of network status of users (on the network, there is no place, etc.) listed in the contact list.

The most popular messengers

1. ICQ. (I Seek You - I'm looking for you) - Popular program (the most common Internet pager) for real-time communication. Since ICQ is an outdated centralized network with a closed protocol, then at present, experts recommend users to switch from the ICQ system to Jabber.
2. Skype. - The most common messenger in the world with a closed protocol. Provides the ability to call in stationary and mobile phones, receive calls. IN recent versions This messenger implements the video call function, with which users can talk and share full-screen video With Web cameras installed from users.
3. Miranda IM. - Multi-protocol messenger instant messaging with open source To work on the Internet or local network. Supports instant messaging protocols: ICQ, IRC, Jabber, Google Talk, Skype and others.
4. Google Talk Client. - Desktop IM client (messenger) Google Talk, and Google Talk Gadget is a web client that works in any browser with ABOBE Flash-plugin. Google Talk is google service for exchange instant messageswhich allows you to communicate with voice chat and text messages. Google Talk uses the XMPP (Jabber-compatible) protocol and allows you to communicate with other members of the Jabber network.
5. Mail.Ru Agent Client. - This is an IM client (messenger), which provides text, voice communication and video chat. Supports ICQ, i.e. It is an ICQ client.
6. Voxox. (Voxox.com, Version 2.0) - modern and promising multiprotocol messenger with open source, which supports ICQ, Jabber, MSN, Yahoo! protocols Messenger and others. VOXOX contains many useful features and makes competition most common to the world Skype messenger.
7. MyChat. - Client-server chat for local, corporate and urban networks.

Organization of News

To facilitate the search for the group of interest, all the news is divided on topics and organized hierarchically, that is, similar questions are in the lists next to each other. Such a structure resembles the structure of the hard disk directories. Programming in C language, for example, is discussed in the news group Comp.Lang.c (here is comp.lang - hierarchy, and C is the name of the conference). Programming on Pascal is near, in the same hierarchy, but a group, as it is easy to guess, is called Pascal. The drawing pictures are published in the hierarchy alt.binaries.clip-art (alt.binaries - the name of the hierarchy, CLIP-ART is the name of the group). With the work of poets and writers in Russian, you can get acquainted in the teleconference of relocom.arts.Qwerty, and with a dollar course in a conference with the characteristic name Relcom.Currency.

Subscribe to teleconference

The most pleasant feature of the subscription is its full automation - the service of subscribers around the clock is engaged in a special program (news server - NewsServer). Any time of day you can subscribe to the topic you like or withdraw a subscription.

Since in many conferences (especially commercial), the volumes of incoming materials are extremely large, then you can only subscribe to the titles of ads (which is much cheaper), and then ordering the articles on them.

What is usenet

Usenet is a community of people exchanging messages (or articles) within one or more teleconferences.

The USENET structure is a set of news servers under different organizations, but usenet itself is not an organization and non-network. Such a service is distributed extremely widely due to the fact that it is supported by a large number of networks and protocols in addition to the Internet.

How the servers are interacting with each other, which protocols and procedures are to use - all this, ultimately, is determined by administrators (Newsmaster) of adjacent servers. At the same time, Usenet does not mean complete freedom. There are certain rules for creating new groups, distributed articles, materials, etc.

ProtocolNNTP.

NNTP (eng. Network News Transfer Protocol) - network ProtocolUsed to exchange messages in teleconferences. In structure, this protocol is largely similar to the SMTP e-mail protocol.

There is a variation of the NNTP protocol, called NNRP (NETWORK News Readers Protocol). It is designed to read conferences from the news server by client software online. Functionally NNTP is focused on the fact that the articles are sent to subscribers when they appear on the server, and NNRP is upon request of the client. Accordingly, NNTP is used to exchange messages between news servers, and NNRP - to read messages from New maintenance and create new messages.

NNTP protocol, like SMTP, is textual. An important feature of the NNTP protocol is its effectiveness in the case of complex collateral graphs between news servers. So that the same message has not been transmitted repeatedly, usually the sending server first reports the identifier of the new message, and the message itself sends only after confirming the receiving party that this message is not yet there

Often the news server hold one or more nntp sessions constantly open, so as not to open them every time again when receiving new messages.

Internet Relay Chat.

IRC (English. Internet Relay Chat is a relayed Internet chat) - a service system, with which you can communicate through the Internet with other people in real time. In Russian computer slang, IRC is called "Irka", "Irz", as well as "Mirk", "Mirka".

IRC is a program that allows you to maintain a lively conversation with a keyboard with people around the world. It is very similar to the international radiotelephone - and even uses "Channels". As soon as the user enters the message on its computer, it will immediately appear around the world for everyone who will be with it on one channel. The user may be engaged in an existing conversation or start its own. There is an opportunity to even create a private channel for a small number of people - at least one or two.

Currently, the IRC combines systems in 20 different countries, from Australia to Hong Kong and Israel. When you connect to the IRC server, the user sees a list of available channels, to each of which (or immediately in several) it can "log in" (connect). The channel is a virtual "room" in which several users can be. All messages issued to the channel are visible to all users who are located only on the same channel. Each channel has its name and, as a rule, a specific topic for discussion. After the "login" on the channel, the user can see that the remaining channel participants are written, and can also write messages. The topic discussed on the channel usually follows from its name (for example, Wikipedia.ru channel).

IRC clients are:

For UNIX-like operating systems: XChat, Kopete, Irssi, Kvirc and IRCII;

For Windows systems: MIRC, XCHAT, IRSSI, KVIRC;

For mobile phones (MIDP): JMirc-M, Snirc.

For OS / 2: OpenChat

IRC provides an opportunity for both group and private communication. For group Chata In IRC, channels are designed on which users can collect and communicate.

Channels, like rooms, can be open to everyone, but there are also closed channels that you can get, having a key, or at a special invitation. The channel can even be secret: in this case it is not visible in the list of channels and, moreover, none of the strangers can see who is in it. This creates good opportunities for conducting private conversations to which no one can interfere.

Each IRC communicating in the IRC has a nick (NICK), on which it is known in the IRC. One of the wonderful features of the IRC is the possibility of parallel communication.

Despite the complexity of the IRC technical device, communication itself eliminates us from some difficulties characteristic of traditional ways communications.

4.1. History of origin

Abbreviation "IRC" means "Internet Relay Chat" and is a system that allows users to conduct a dialogue with other Internet users. Originally, IRC was developed in 1988, Jarkko Oikarinen and has spread all over the world over the world. Although the initial system was conceived as the expansion of the Talk program intended to communicate two users of UNIX systems, the results exceeded all expectations - the new communication system has occurred, which has changed the lives of many people.

IRC began to conquer specially popularity after the operation "Storm in the Desert" (1991), when messages from all over the world were collected in one place and online broadcast in IRC. Similarly, the IRC was used in 1993, during the coup in Russia, when users from Moscow in real time reported to the world about what was happening on the streets. What can IRC give? First, the joy of communication. The IRC come to spend time - so, MTV or Zhurnal.ru are periodically arranged at the IRC conference, which is invited to famous musicians or writers. On IRC you can find new friends; Communicate on professional topics, discuss the last film much more. There are real-time learning technologies using IRCs.

Pros and consIRC.

The main advantages of IRC are:

IRC consumes a very small amount of traffic, which is especially important with the internet limit tariff board.

IRC allows the user to communicate with many people from other cities and countries.

IRC is the ability to make permanent online acquaintances and calculate them when they appear in IRC.

IRC is a flexible tool so that people can appreciate your ingenuity, resourcefulness and sophistication.

Delays when working with IRC do not exceed a few seconds. This is due to the fact that the computer does not need to install dozens of connections with other countries - it is enough to connect to the nearest IRC server.

Unfortunately, the IRC system is not devoid of disadvantages.

As neither regrettable, but it became a kind of place of meetings of the most unpleasant personalities, the purpose of which is not to communicate with other people, but to spoil them the mood. They make it with the help of various kinds of packages, such as mailing programs with "surprises" (flooding) (flooding) (sending large amounts of data or repetition of a certain sequence of actions that interfere with conducting a conversation to other users), all kinds of purates, Curses - in general, who is what is much. There are many ways to protect against such people, but it is completely difficult to get rid of them. Procedure control in the IRC network is operators.

Why do you need operators?

Channel operators are the main on IRC channel. They differ in the symbol "@" in front of the pseudonym. As a rule, the status of the operator may be freely transmitted (or taken) by other operator. The operator (or, abbreviated, OP) may pour (throw out) from the channel of other users, block the entrance to a specific channel for some mask, etc. The status of the operator is valid only within the same channel.
IRC operators are the IRC network managers. As a rule, these are administrators of IRC servers; They do not interfere in internal conflicts and remind of their presence only when someone tries to prevent the IRC network normal operation. The IRC operator can "throw out" the user from the network or even completely block the input to the IRC network.

To work with IRC, a special client program is needed. For UNIX systems, the most common client - XChat. Under Windows is the MIRC program. It is easy to configure and install so much that 90% use it precisely and often do not know people call the IRC Mirk. Next you need to connect to the server. To do this, you need to dial / server www. Server .NET server.

After connecting to the server, you can find the right person and communicate with it. You can also connect to the channel. Channel communication resembles people's communication in the room. Someone says, and everyone hears him. Each channel has a name that reflects the general topics of the conversation. This can be both the topic of interest to all, and simply some unifying the name. If in the first case the conversations are usually carried out around the specified theme, then in the second case, the conversations are carried out on completely different topics.
Bots are programs that are connected to the IRC server and can perform special operations. In addition to supporting the status of the operator, the bots can perform the functions of the bulletin board, can display information about the usern a user and have many other useful features.
If there are questions, but for the answer to the questions there is a specialized Channel #help, it exists on any self-respecting server or network. It is possible to make it yourself and moderate the channel in the IRC.

IRC.-Seti

The IRC client program establishes a connection to the nearest IRC server. IRC servers are combined with each other. Thus, it turns out a kind of "network in the network" - it is enough to connect to any server to start communicating. Channel names start with "lattice" ("#"), this is a generally accepted agreement.

In order to select a channel, you can use the list that offers a client program. The IRC network consists of servers. The server can be connected to other servers. A combination of servers connected to each other forms a network. Initially, there was only one network IRC, but later she split into several parts (IRCNET, EFNET), new networks appeared (GalaxyNet, Undernet, others) and this process continues.

Today we will talk about configuring IRC services,
and this topic will be covered by
admin, that is, you \u003d). Being
user in IRC, you can be already familiar with
Services and know almost all of their teams, but
Believe the administrator to be much more interesting \u003d).

So, you have a customized and raised
IRCD, let it be unreal. Download services
Hence: http://kamensk.net.ru/forb/1/ircservices-4.5.41.tar.gz.
Download them, and proceed to edit
IRCD.CONF (IRCD config). Services are present
a separate server, so IRCD should
be compileged like hub and having c / n linets on
Services. Propying them, as follows:

C: 192.168.0.1: Services: Services.Local.net :: 50
N: 192.168.0.1: Services: Services.Local.net :: 50

Considering that your grid is called
Local.Net, and services start from the host 192.168.0.1 (maybe
From there it starts and IRCD). Password by
Services will make "Services" (I recommend it
remake so that some kind of ghoul
Reconnected on IRCD under services \u003d)), class
Connect 50, the port is not specified.

You did not think about why services
All allowed (distribute opov to the right and
left, throw users and even change
their nicknames)? For this responds with U-Line in IRCD.conf. Mask
falling under this line can do everything
on the this server, so we prescribe:

U: Services.Local.net: *: *

This is the IRCD.CONF configuration is complete. Send
Server SIGINT signal (not to be confused with SIGKILL \u003d))
command killall -1 IRCD, or type "/ Rehash" in
Ira on your server (but for this you
Must be at least the server administrator).

Now we will deal with the services themselves.
Lawfigure them, registering the directory for
binaries and second, for libraries (including
including Services.conf). Then, in order Make, make install.
It seems to be all \u003d).

Let us turn to the configuration of the Confinal. The file must
be called serivces.conf and lie in the directory
which you pointed out in configure for libraries.
Briefly about its configuration (I write to all
Correctly started and a little about important
variables):

RemoteServer - Analogue of C / N Launov in IRCD.conf. Format:
server port "password" boldly fill
With its data:

RemoteServer 192.168.0.1 6667 "Services"

ServerName - the name of the server under which will be
Link services. We asked him, this is a name.
Services.local.net:

ServerName "Services.local.net"

ServerDesc - Description for server, invent your own
=)

ServerDesc "Services for Local Irc Daemon"

ServiceUser - mask under which will perform
All services of this network. Do it [Email Protected]
for clarity:

Next are the specific settings for
each service (for example, when dropping
Nick on Taimaut, or how many clones
allow for a connector to the server). With these
In the subtleties, I hope you will figure it out.
It is worth entering only your nickname to the SERVICESROOT part,
To be an administrator of services.

After setting, we try to start the services.
Go to the directory with binary and
Start them - "./Services". If everything is ok
The server will tell you about the new line, and NickServ
Asked to register nickname \u003d). IN
otherwise see the confes (99% in them
something wrong) or logs of services (by
default Services.log in the directory with
libraries and confamps).

Now actually about control \u003d). After
how did you register your nickname that
coincides with the nickname in the SERVICESROOT variable (if
You did not know to register nickname
"/ NS Register password_nik [Email Protected]"), and then
became an opera on the IRCD, you automatically
Assign the title Services Administrator. Thereafter
Commands: "/ OS Set Supass Password" to
Install the password on the super-user operators \u003d), which
Can perform all operations on services.
For this status you need
Pick up: "/ OS SU password." To add
in service admins of someone else, dial "/ os
Oper Add Nick ", where Nick is a person whom
add \u003d). After all the above,
Make "/ OS Update" to save the databases.

And now about the possibilities \u003d). The fact is that
Through Opersion Perhaps Slent RAW messages
all services, for example, to change nickname
Someone is enough to dial: "/ OS RAW: NickServ
svsnick nick nick2 1 ", where Nick is the current nickname, nick2 - nickname
To which you want to change the current \u003d). Also,
Through the same RAW you can join on the canal
Services, similar to (no restrictions),
But do not abuse: if any
The service is glucinet, then all services will fall \u003d). I
Not talking about such banal opportunities,
like / OS Akill or / OS Mode, about them I think you are all
You know, otherwise - / OS Help.

"/ OS jupe server.name" wounds \u003d) server in your
networks (this happens if necessary
the server is not all right, the services would like
emulate connections, but in fact the server-victim
It will not be online). To cancel JUPE,
Make the Squit service, the / Squit Server.name command.

So services consist of:
NickServ - Heads the Base
ChanServ - Heads Channel Channels
Memoserv - Message Server
Operserv - Heads of Service \u003d)
Global - Displays Global Messages
Devnull - trash 😉 through it
communicate with each other.
Helpserv - Help for all services.

Yes, I have not yet said that the admin can without
problems learn user password on nickname or
canal, or drop something without any
That restrictions. But, do not abuse it
Otherwise you do not like users, and about you
There will be a bad opinion.

As you probably understood, with services online
Much more fun than without them. Yes, and that
High-organized grids have their own
Services, it has already become the standard IRC network \u003d).
