我有一个正在运行的 docker 容器Ubuntu 18.04。

我使用以下命令运行它，但是如果我关闭接口，无论我做什么，即使它说接口已启动，我也无法再与其建立任何连接。

docker run --hostname=hello.world --cap-add=NET_ADMIN -it test-ubuntu18

在我的容器中，我曾经ip link set eth0 down暂时禁用网络，但是一旦我重新打开它，就没有任何作用。

这是我的 Dockerfile

FROM ubuntu:18.04 as base

# Install base dependencies
RUN apt-get update && apt-get install -y -q --no-install-recommends \
    apt-transport-https build-essential ca-certificates curl dbus git \
    iputils-ping libssl-dev net-tools network-manager vim wget systemd \
    sudo rsyslog

ENV NVM_DIR /root/.nvm
ENV NODE_VERSION 17

RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash \
    && . $NVM_DIR/nvm.sh \
    && nvm install $NODE_VERSION \
    && nvm alias default $NODE_VERSION \
    && nvm use default

# Fix rsyslog start up by disable imklog
RUN sed -i 's/module(load="imklog"/#module(load="imklog"/' /etc/rsyslog.conf

ENTRYPOINT service rsyslog start && \
           service dbus start && \
           service network-manager start && \
           bash

有谁知道是否可以使用 docker 容器重新启用网络？

我有一个非常奇怪的问题。我已经设置了我的私人 yum 存储库，它提供的 rpm 很好，除了 1 rpm。

假设我已经构建并复制了所有 rpm 到我的自定义存储库目录，大致如下：

postgresql-myStuff11-11.7-2.el8.x86_64.rpm
postgresql-myStuff11-libs-11.7-2.el8.x86_64.rpm
postgresql-myStuff11-devel.7-2.el8.x86_64.rpm
postgresql-myStuff11-docs-11.7-2.el8.x86_64.rpm
...

所有这些都在那里，我已经清除了我的 yum 缓存，使用重建了我的 yum 存储库，createrepo --update甚至删除了整个repodata文件夹并重新创建它等。但无论我做什么，当我运行yum search myStuff（或myStuff11 等）。

它只会返回除主包之外的所有其他内容。

Searching Packages:
==========================================================================================
Name Matched: myStuff11
==========================================================================================
postgresql-myStuff11-libs.x86_64 : The shared libraries required for any PostgreSQL clients
Repo        : @System
Matched from:
Provide    : postgresql-myStuff11-libs = 11.7-2.el8
...

起初，我认为这可能是因为Name:我的规范文件内部使用了定义的变量，但即使在我将其更改为字符串之后，它仍然是完全相同的东西......

问题：

  • 你如何才能yum看到包裹postgresql-myStuff11-11.7-2.el8.x86_64.rpm？

我正在尝试在 LDAP 中创建一个用户，该用户使用带有 groupOfNames 的对象类 inetOrgPerson（所以我可以使用属性'member'），但无论我尝试哪种组合，它都不会让我这样做。使用“成员”属性的正确方法是什么？

这是我尝试通过 Apache Directory Studio 添加它时收到的错误消息。
