Vagrant 端口转发不起作用.主机无法使用杯子 [英] Vagrant port forwarding not working. Cups not accesible from host

问题描述

所以我正在使用 vagrant 并且我正在尝试将其用作打印服务器.我安装了杯子.

So I'm working with vagrant and I'm trying to use it as a printing server. I installed cups.

在内部一切正常.我什至可以快速 curl 到我的 localhost:631(我的 vagrant 中的杯子端口)，然后就可以了.

Internally everything works just fine. I can even make a quick curl to my localhost:631 (cups port inside my vagrant) and there's everything.

问题是我无法通过主机尝试以任何方式访问它.

The thing is I cant access it in any way I try from the host machine.

显然我转发了端口，并且尝试了几个端口.我也尝试过 Debian 挤压和 Ubuntu 12.04.这是我当前的 Vagrantfile

Obviously I forwarded the port and I've tried with several ports. I've also tried with Debian squeeze and Ubuntu 12.04. Here is my current Vagrantfile

Vagrant.configure("2") do |config|                                              
  config.vm.box = "guruDebian"
  config.vm.network :forwarded_port, guest: 80, host: 8080
  config.vm.network :forwarded_port, guest: 631, host: 6363   ## HERE IS CUPS           
end

有什么想法吗?

推荐答案

我想你会发现，出于安全原因，默认的 cups 配置文件被锁定为只能在本地主机上工作.

I think what you will find is that the default cups config file is locked down to only work from localhost for security reasons.

在您的 Vagrant VM 中打开 /etc/cups/cupsd.conf 文件并更改以下行:

Inside your Vagrant VM open the /etc/cups/cupsd.conf file and change the following line:

Listen localhost:631

到

Listen 0.0.0.0:631

这应该允许您从任何主机连接.

That should allow you to connect from any host.
