如何将IntelliJ IDEA随机开放端口绑定到localhost？ [英] How to bind IntelliJ IDEA random open ports to localhost only?

问题描述

当我在macOS上运行IntelliJ IDEA 2018.1.6（终极版或社区版）时，我发现在所有网络接口（eth0，lo，...）上都打开了3个随机端口。一个随机端口是通过构思过程打开的，另外两个端口是由IntelliJ IDEA启动的另一个java进程打开的。

我删除了唯一的插件I'已明确安装哪个是SonarLint。

在端口63342上运行的调试器绑定到localhost，这可以在Preferences菜单中配置。

以下是输出的相关部分lsof -i | grep LISTEN ：

  idea 3328 orto 187u IPv4 0x3c332685aa6872fd 0t0 TCP localhost：6942（LISTEN）
 idea 3328 orto 686u IPv4 0x3c332685aa623815 0t0 TCP localhost：63342（LISTEN）
 idea 3328 orto 752u IPv4 0x3c332685aa676de5 0t0 TCP *：53212（LISTEN）
 java 3341 orto 33u IPv6 0x3c332685aa5f899d 0t0 TCP *：61070（ LISTEN）
 java 3341 orto 77u IPv6 0x3c332685b9885edd 0t0 TCP *：53210（LISTEN）
  

As问，这是 ps -ef |的相关部分grep 3341 （它是一个RemoteMavenServer）：

如何将这三个随机开放端口绑定到localho st？

PS：我使用的是macos版本。

PS2：此处创建了一个问题：

When I run IntelliJ IDEA 2018.1.6 (Ultimate or Community edition) on macOS, I observe that 3 random ports are open on all network interfaces (eth0, lo, ...). One random port is open by the idea process and the two other ports are open by a different java process launched by IntelliJ IDEA.

I've removed the only plugin I've explicitly installed which is SonarLint.

The debugger which is running on port 63342 is bind to localhost and this can be configured in the Preferences menu.

Here is the relevant part of the output of lsof -i | grep LISTEN :

    idea   3328    orto  187u  IPv4 0x3c332685aa6872fd   0t0  TCP localhost:6942 (LISTEN)

How to bind these three random open ports to localhost?

P.S.: I am using the macos version.

P.S.2: An issue has been created here: https://youtrack.jetbrains.com/issue/IDEA-175889.

解决方案

IntelliJ IDEA doesn't bind any ports on the wildcard interface by default, except for the UDP concurrent licensing check (only for Ultimate). All the ports used for internal needs (Netty library initialization, exclusive folders lock, built-in web server, debugger, compiler/maven/gradle/running process IPC) are open on the localhost (127.0.0.1) interface:
