Although traditional PPP is a peer-to-peer protocol, PPPoE is inherently a client-server relationship since multiple hosts can connect to a service provider over a single physical connection. The discovery process consists of four steps between the host computer which acts as the client and the access concentrator at the Internet service ...
MS-CHAP-v2 is vulnerable to dictionary attacks on the captured challenge response packets. Tools exist to perform this process rapidly. [8] In 2012, it was demonstrated that the complexity of a brute-force attack on a MS-CHAP-v2 key is equivalent to a brute-force attack on a single DES key. An online service was also demonstrated which is ...
The server does not meet one of the preconditions that the requester put on the request header fields. 413 Payload Too Large The request is larger than the server is willing or able to process. Previously called "Request Entity Too Large". [16]: §10.4.14 414 URI Too Long The URI provided was too long for the server to process. Often the result ...
During this handshake, the client and server agree on various parameters used to establish the connection's security: The handshake begins when a client connects to a TLS-enabled server requesting a secure connection and the client presents a list of supported cipher suites (ciphers and hash functions).
The C10k problem is the problem of optimizing network sockets to handle a large number of clients at the same time. [1] The name C10k is a numeronym for concurrently handling ten thousand connections. [2]
A server process first creates a named server connection port object, and waits for clients to connect. A client requests a connection to that named port by sending a connect message. If the server accepts the connection, two unnamed ports are created: client communication port - used by client threads to communicate with a particular server
The remote server sends a response to the client, and the application continues its process. While the server is processing the call, the client is blocked (it waits until the server has finished processing before resuming execution), unless the client sends an asynchronous request to the server, such as an XMLHttpRequest.
Before a client attempts to connect with a server, the server must first bind to and listen at a port to open it up for connections: this is called a passive open. Once the passive open is established, a client may establish a connection by initiating an active open using the three-way (or 3-step) handshake:
