/*server.go */
package main
import (
"bufio"
"fmt"
"net"
"time"
)
func main() {
var unixAddr *net.UnixAddr
unixAddr, _ = net.ResolveUnixAddr("unix", "/tmp/unix_sock")
unixListener, _ := net.ListenUnix("unix", unixAddr)
defer unixListener.Close()
for {
unixConn, err := unixListener.AcceptUnix()
if err != nil {
continue
}
fmt.Println("A client connected : " + unixConn.RemoteAddr().String())
go unixPipe(unixConn)
}
}
func unixPipe(conn *net.UnixConn) {
ipStr := conn.RemoteAddr().String()
defer func() {
fmt.Println("disconnected :" + ipStr)
conn.Close()
}()
reader := bufio.NewReader(conn)
for {
message, err := reader.ReadString('\n')
if err != nil {
return
}
fmt.Println(string(message))
msg := time.Now().String() + "\n"
b := []byte(msg)
conn.Write(b)
}
}
/* client.go */
