It can adjust transmission rate and data size as needed, and report bandwidth, jitter, and packet loss. Download: https://github.com/esnet/iperf/ i...
Developing a concurrent chat server involves managing multiple simultaneous TCP connections while ensuring thread-safe message distribution. This implementation leverages the Winsock2 API alongside C++11 concurrency primitives to build a multi-user messaging platform supporting both direct messaging...
When monitoring a Zabbix agent, an alert indicated unavailability despite the agent process running. Checking network cnonections revealed numerous TCP connections in the TIME_WAIT state, prevanting new connections to the proxy due to exhausted socket resources. In active mode, the agent initiates c...
TCP provides a reliable, ordered, byte-stream channel between two endpoints. In application code, endpoints are explicitly divided into a client that initiates a connection and a server that listens for and accepts connections. A server must be running before any client can connect. Roles and connec...
