Sim*_*een 100 network-manager networking services
在Ubuntu 14.04没有sudo service networking restart，也没有sudo /etc/init.d/networking restart任何更多的做任何事情。他们也都以代码 1 退出。显然有些事情发生了变化（或发生了一半变化），但我找不到什么。这显然会导致远程网络重新配置和 Ansible 等工具出现问题。

在 Ubuntu 14.04 Server 中远程重启网络的正确方法是什么？
Sim*_*een 126
原来这是一个“功能”。在 Ubuntu Server 中重新启动界面的唯一支持的方法是sudo ifdown eth0 && sudo ifup eth0
https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1301015
dpb*_*dpb 73
ifdown, ifup 对我不起作用（可能是第二个命令之前的 SSH 连接超时）。有效的是：
sudo service network-manager restart
这是在 14.04 ubuntu-desktop 系统上。
改变的是他们不再希望你“弹跳”网络。停止和启动，仍然有效。重新启动不再有效。我只是“解决”了这个“问题”，也就是说我恢复了旧的行为。恢复到之前的行为：获取 13.10 /etc/init/networking.conf 文件并用它替换 14.04 文件。（编辑：澄清哪个取代了哪个）
该过程如下所示：

对 /etc/init.d/networking 脚本执行相同的操作，这是 /etc/init/networking.conf 文件引用/调用的内容。

显然，他们在那里设置防守出口是有原因的，但他们并不费心去真正输出正在发生的事情。
当您尝试时，条目确实会进入 /var/log/upstart/networking.log，如下所示：
Stopping or restarting the networking job is not supported.
Use ifdown & ifup to reconfigure desired interface.
但是当您尝试重新启动服务网络时，他们确实可以/应该将其输出为对话框消息。呃，好吧。想通了，甚至是一种老方法。
编辑：我发现这会导致无意触发由 /etc/init/failsafe.conf 控制的脚本，这是不可取的，因为它会在每次启动时导致 120 秒的超时延迟......以及可能掩盖实际的错误配置/网络这种延迟的出现表明的问题，但它已经一直在显示。（例如，一根未插入的电缆，它允许访问映射在 /etc/fstab 中的网络文件共享，例如）
在任何情况下，我都会找出导致这总是超时的原因，并在找到时发布修复程序。
