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

Unix Sockets in Go
I'm trying to make a simple echo client and server that uses Unix sockets. In this example, the connection seems to be unidirectional. The server can receive data from the client, but it can't send the data back. If I use tcp connections instead, it works great. Does anyone know what's wrong? Server package main import "net" import "fmt" func echoServer(c net.Conn) { for { buf := make([]byte, 512)
