CentOS CUPS配置

Question

我有一个关于为CentOS配置CUPS的问题。我在一台机器上安装了CUPS，我正在尝试从另一台机器访问CUPS的web界面。具有CentOS和CUPS的机器的IP为10.0.0.1，第二台机器的IP为10.0.0.2。我有一个网络打印机的IP设置为10.0.0.10，这两台机器可以平打印机。但是第二台机器不能通过web接口访问CentOS机器。

下面是我的cupsd.conf文件的一部分：

SystemGroup sys root

Listen *:631
Browsing On
BrowseOrder allow,deny
BrowseAllow all
BrowseAddress 10.0.0.2:631

<Location />
    Order allow,deny
    Allow from 10.0.0.2
</Location>

<Location /admin>
    Order allow,deny
    Allow from 10.0.0.2
</Location>

<Location /admin/conf>
    AuthType Default
    Require user @SYSTEM
    Order allow,deny
    Allow from 10.0.0.2
</Location>

我还在某个地方读到CentOS的CUPS需要，是这样的吗？

Answer 1

CUPS不需要SSL证书。您可以通过将DefaultEncryption Never添加到配置文件并重新启动守护进程来禁用https。在最近版本的CentOS (您没有指定正在运行的版本)中，web接口中有一个“允许远程管理”复选框，它将在端口631上提供远程CUPS管理页访问。在您的例子中，浏览到：https://10.0.0.1:631/admin

下面是我倾向于在新系统上部署的标准CUPS文件。
