Variables

var (
	IP         = "ip"
	Nft        = "nft"
	Resolvectl = "resolvectl"
	Sysctl     = "sysctl"
)

default values.

var RunCmd = func(ctx context.Context, cmd string, s string, arg ...string) (stdout, stderr []byte, err error) {
	c := exec.CommandContext(ctx, cmd, arg...)
	if s != "" {
		c.Stdin = bytes.NewBufferString(s)
	}
	var outbuf, errbuf bytes.Buffer
	c.Stdout = &outbuf
	c.Stderr = &errbuf
	err = c.Run()
	stdout = outbuf.Bytes()
	stderr = errbuf.Bytes()
	return
}

RunCmd runs the cmd with args and sets stdin to s, returns stdout and stderr.
