The connection port field indicates the TCP source port used by the requesting client. Previously, IP address and client connection port information were available only in C
How TCP backlog works in Linux
When an application puts a socket into LISTEN state using the listen syscall, it needs to specify a backlog for that socket. The backlog is usually described as the limit for the queue of incoming connections. Because of the 3-way handshake used by TCP, an incoming connection goes through an intermediate state SYN RECEIVED before it reaches the ESTABLISHED state and can be returned by the accept s

Scaling Linux Services: Before accepting connections
More posts When writing services that accept TCP connections, we tend to think of our work as starting from the point where our service accepts a new client connection and finishing when we complete the request and close the socket. For services at scale, operations can happen at such a high rate that some of the default resource limits of the Linux kernel can break this abstraction and start caus
