Pentaho data integration ，从官方下载下来最新的安装包，解压之后，双击Data Integration，报安全问题，询问是否打开，同意并输入自己的开机密码。然后，等了几秒，发现没有任何反应，再次双击Data Integration，依然没有任何相应。

以为程序不兼容。但想想不应该，搜了一下，发现可能是权限的问题，说是直接运行 spoon.sh 可以运行。试了一下，确实OK。但不可能一直这样执行。继续找解决方案，最后居然是这么简单，运行一下：

这个问题在2017年就有人遇到了，看这里：https://edpflager.com/?p=3571，参考 一下即可。

现在，程序终于可以运行了

最后附上一堆教程：

 上一篇博客说了。我用vsc的ssh-remote的时候，30秒或者1分钟必断。错误信息一直就类似：

[04:30:38.609] Install terminal quit with output:

重连后也是

发了ticket给layerstack。他们测试也来没有这个问题。我开始以为是什么openfiles limit的问题。也打开到最大了。

期间调整了一下这个：echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p，因为开始有报inotify max error

直到他们给我发了一个ticket：

Thank you for your patience in this matter.

We have investigated the issue in detail and we are not able to recreate the issue from our end. We have checked the same from multiple locations and find out its working fine.

The reported issue seems to be related to your local ISP, so we suggest you to change the standard port (22) of SSH to some other non standard port like 2222 or 2244, in server and recheck the issue.

Please do have a check on our above suggestion and let us know if you still face any issues in accessing.

所以我就想了一下，直接把PORT改成了2222，2223，2244，然而仍然 失败，最后我用了一个超大端口，居然正常了
