IrcII
ircII (pronounced ''i-r-c-two'' or ''irk-two'', and sometimes referred to as ''IRC client, second edition'') is a free, open-source Unix IRC and ICB client written in C. Initially released in the late 1980s, it is the oldest IRC client still maintained. History Several other UNIX IRC clients, including BitchX, EPIC, and ScrollZ, were originally forks of ircII. It was the first client to implement file transfer capabilities over IRC. The CTCP protocol was implemented by Michael Sandrof in 1990 for version 2.1. The DCC protocol was implemented by Troy Rollo in 1991 for version 2.1.2, and was never intended to be portable to other IRC clients. Features ircII is written in the C programming language and implements a termcap, text-mode, user interface. Encrypted Transport Layer Security connections to IRC servers are established with the OpenSSL library. The concept of file transfers over IRC networks was first implemented by the authors of ircII. The client was the first to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Direct Client-to-Client
Direct Client-to-Client (DCC) (originally Direct Client Connection) is an IRC-related sub-protocol enabling peers to interconnect using an IRC server for handshaking in order to exchange files or perform non-relayed chats. Once established, a typical DCC session runs independently from the IRC server. Originally designed to be used with ircII it is now supported by many IRC clients. Some peer-to-peer clients on napster-protocol servers also have DCC send/get capability, including TekNap, SunshineUN and Lopster. A variation of the DCC protocol called SDCC (Secure Direct Client-to-Client), also known as DCC SCHAT supports encrypted connections. An RFC specification on the use of DCC does not exist. DCC connections can be initiated in two different ways: * The most common way is to use CTCP to initiate a DCC session. The CTCP is sent from one user, over the IRC network, to another user. * Another way to initiate a DCC session is for the client to connect directly to the DCC server. ...

Client-to-client Protocol
Client-to-client protocol (CTCP) is a special type of communication between Internet Relay Chat (IRC) clients. CTCP is a common protocol implemented by most major IRC clients in use today. CTCP extends the original IRC protocol by allowing users to query other clients or channels, this causes all the clients in the channel to reply the CTCP, for specific information. Additionally, CTCP can be used to encode messages that the raw IRC protocol would not allow to be sent over the link, such as messages containing newlines or the byte value 0 (NULL). CTCP does not establish a direct connection between clients; however, it is commonly used to negotiate DCC connections. CTCP allows users to query a remote client about the version of the client they are using (via CTCP VERSION), or the time (via CTCP TIME), among other things. It is also used to implement the /me command (via CTCP ACTION). History ircII was the first IRC client to implement the CTCP and DCC protocols. The CTCP protocol ...

BitchX
BitchX is a free IRC client ("If you're already using Linux, then you have your choice of several (IRC) clients. BitchX is a popular one.") and has been considered to be the most popular ircII-based IRC client. The initial implementation, written by "Trench" and "HappyCrappy", was a script for the IrcII chat client. It was converted to a program in its own right by panasync (Colten Edwards). BitchX 1.1 final was released in 2004. It is written in C and is a TUI application utilizing ncurses. GTK+ toolkit support has been dropped. It works on all Unix-like operating systems, and is distributed under a BSD license. It is originally based on ircII-EPIC and eventually it was merged into the EPIC IRC client. It supports IPv6, multiple servers and SSL and a subset of UTF-8 (characters contained in ISO-8859-1) with an unofficial patch. BitchX has frequently been noted to be a popular IRC client for Unix-like systems. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Internet Relay Chat Clients
Internet Relay Chat (IRC) is a text-based chat system for instant messaging. IRC is designed for group communication in discussion forums, called ''channels'', but also allows one-on-one communication via private messages as well as chat and data transfer, including file sharing. Internet Relay Chat is implemented as an application layer protocol to facilitate communication in the form of text. The chat process works on a client–server networking model. Users connect, using a clientwhich may be a web app, a standalone desktop program, or embedded into part of a larger programto an IRC server, which may be part of a larger IRC network. Examples of programs used to connect include Mibbit, IRCCloud, KiwiIRC, and mIRC. IRC usage has been declining steadily since 2003, losing 60 percent of its users. In April 2011, the top 100 IRC networks served more than half a million users at a time. History IRC was created by Jarkko Oikarinen in August 1988 to replace a program cal ...

List Of Internet Relay Chat Commands
This is a list of all Internet Relay Chat commands from RFC 1459, RFC 2812, and extensions added to major IRC daemons. Most IRC clients require commands to be preceded by a slash ("/"). Some commands are actually sent to IRC bots; these are treated by the IRC protocol as ordinary messages, not as /-commands. Conventions used here: Angle brackets ("<" and ">") are used here to indicate a placeholder for some value, and are not a literal part of a command. Square brackets (" and ") are used to indicate that a value is ''optional''. User commands ADMIN Syntax: :ADMIN .html" ;"title="nowiki>">nowiki>/code> Instructs the server to return information about the administrators of the server specified by , where is either a server or a user.

OpenSSL
OpenSSL is a software library for applications that provide secure communications over computer networks against eavesdropping or need to identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites. OpenSSL contains an open-source implementation of the SSL and TLS protocols. The core library, written in the C programming language, implements basic cryptographic functions and provides various utility functions. Wrappers allowing the use of the OpenSSL library in a variety of computer languages are available. The OpenSSL Software Foundation (OSF) represents the OpenSSL project in most legal capacities including contributor license agreements, managing donations, and so on. OpenSSL Software Services (OSS) also represents the OpenSSL project for support contracts. OpenSSL is available for most Unix-like operating systems (including Linux, macOS, and BSD), Microsoft Windows and OpenVMS. Project history The OpenSSL ...

Transport Layer Security
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible. The TLS protocol aims primarily to provide security, including privacy (confidentiality), integrity, and authenticity through the use of cryptography, such as the use of certificates, between two or more communicating computer applications. It runs in the presentation layer and is itself composed of two layers: the TLS record and the TLS handshake protocols. The closely related Datagram Transport Layer Security (DTLS) is a communications protocol providing security to datagram-based applications. In technical writing you often you will see references to (D)TLS when it applies to both versions. TLS is a proposed Internet Engineering Task Force (IETF) standard, first defined in 1999, and the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termcap
Termcap (''terminal capability'') is a software library and database used on Unix-like computers. It enables programs to use display computer terminals in a device-independent manner, which greatly simplifies the process of writing portable text mode applications. Bill Joy wrote the first termcap library in 1978 for the Berkeley Unix operating system; it has since been ported to most Unix and Unix-like environments, even OS-9. Joy's design was reportedly influenced by the design of the terminal data store in the earlier Incompatible Timesharing System. A termcap database can describe the capabilities of hundreds of different display terminals. This allows programs to have character-based display output, independent of the type of terminal. On-screen text editors such as vi and emacs are examples of programs that may use termcap. Other programs are listed in the Termcap category. Examples of what the database describes: *how many columns wide the display is *what string to sen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C Programming Language
''The C Programming Language'' (sometimes termed ''K&R'', after its authors' initials) is a computer programming book written by Brian Kernighan and Dennis Ritchie, the latter of whom originally designed and implemented the language, as well as co-designed the Unix operating system with which development of the language was closely intertwined. The book was central to the development and popularization of the C programming language and is still widely read and used today. Because the book was co-authored by the original language designer, and because the first edition of the book served for many years as the ''de facto'' standard for the language, the book was regarded by many to be the authoritative reference on C. History C was created by Dennis Ritchie at Bell Labs in the early 1970s as an augmented version of Ken Thompson's B. Another Bell Labs employee, Brian Kernighan, had written the first C tutorial, and he persuaded Ritchie to coauthor a book on the language. Ker ...
