The following example shows how to connect a client socket program to a connection-oriented server. Well, let try the client program that will connect to the previous server program. Beware codes that expand more than one line.Д®xample: Connecting a TCP client to a server, a client program The Fedora machine used for the testing having the ' No Stack Execute ' disabled and the SELinux set to default configuration.

Once a socket is fully built up as a network communication endpoint, we can use the socket id like a file descriptor in read and write system calls. After initialization, it is built up as a network communication end point using calls like bind, listen, connect, accept, etc. A socket is initialized with the socket system call. A socket is a network communication end point at a host. The client and server processes communicate over sockets. A list of reserved port numbers is available in the file, /etc/services. For example, port numbers 25 and 587 are for SMTP, 80 is for HTTP, 443 is for HTTPS, port 993 is for IMAPS, etc. Port numbers less than 1024 are well known port numbers and identify popular services. A process, wishing to communicate over the network is linked to a unique port number on the host on which it is running. More specifically, the client needs to know the port number for the server process. Next, the client needs to identify the server process on that host. In order to have unambiguous representation, there can be only one occurrence of adjacent colons in an IPv6 address.ДЄn IP address identifies a host on the network. Missing digits between two adjacent colons are zeroes. Leading zeros are omitted which means that, as an example, db8 is actually 0db8 and 1 is 0001. Or, the IP address can, alternately, be a 128-bit newer IPv6 address, expressed, for example, as 2001:db8::1:2:3:4, where colons are used as punctuation to improve readability and each character is a hexadecimal digit representing four bits of address.

The IP address can be a traditional IPv4 32 bit address written, for example, as 203.0.113.10, where each number represents the contents of a byte. How does a client identify the server with which it wants to communicate? A client needs to know two things about the server - the Internet Protocol (IP) address of the host computer on which the server resides and the port number on that host for the server process. In this post we will look at the Transmission Control Protocol (TCP) for full-duplex communication between a server and its clients. As host computers have a loopback network interface and processes on a host can also use network protocols for communication among themselves, a client can also reside on the same host as the server. Some of the examples of these services are booking an airline ticket and/or a room in a hotel, sending a file to a client, sending a mail message to another person (client), etc. A server has information resources and processes that provide answers to queries and other services to remote clients over the network.

Client server model is a software architecture paradigm prevalent in distributed applications.
