I think I made some progress.... I think. Is it right what I'm doing ?
................
cmd.Stdin = conn
// cmd.Stdout = conn
// data := []byte(cmd.Stdout)
data := cmd.Stdout
var i int
for {
n := int(math.Min(float64(rand.Intn(len(data))), float64(len(data))))
d := data[i : i+n]
i += n
time.Sleep(400 * time.Millisecond)
d = conn
if i >= len(data) {
break
}
}
cmd.Stderr = conn
cmd.Run()
............................
But when I try to build I get these errors:
conn.go:75:46: invalid argument data (type io.Writer) for len
conn.go:76:16: cannot slice data (type io.Writer)
conn.go:83:22: invalid argument data (type io.Writer) for len
