2.7.13 的 dubbo 的 qos
```java
if (extensionLoader.hasExtension(command)) {
if (extensionLoader.hasExtension(command)) {
if (commandEnabled(channel.getUrl(), command)) {
try {
String result = extensionLoader.getExtension(command).telnet(channel, message);
if (result == null) {
return null;
}
buf.append(result);
} catch (Throwable t) {
buf.append(t.getMessage());
}
} else {
buf.append("Command: ");
buf.append(command);
buf.append(" disabled for security reasons, please enable support by listing the commands through 'telnet'");
}
} else {
buf.append("Unsupported command: ");
buf.append(command);
}
}
```
```java
private boolean commandEnabled(URL url, String command) {
String supportCommands = url.getParameter(TELNET);
if (StringUtils.isEmpty(supportCommands)) {
return false;
}
String[] commands = COMMA_SPLIT_PATTERN.split(supportCommands);
for (String c : commands) {
if (command.equals(c)) {
return true;
}
}
return false;
}
```
在下边校验的时候出错了。

尝试使用3.0最新版试下呢，另外ls命令只能在qos开启的情况下有效

先说解决 直接添加配置，dubbo.provider.telnet = ls,ps,cd,pwd,trace,count,invoke,select,status,log,help,clear,exit,shutdown 配置解决
Dubbo 在telnet的时候加了判断，会判断Provider上的信息，如果没配置现在是无法telnet了的哈
