我有一个关于为 CentOS 配置 CUPS 的问题。我在一台机器上的 CentOS 上安装了 CUPS,我正尝试从另一台机器访问 CUPS 的 Web 界面。装有 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,其 IP 为 10.0.0.10,两台机器都可以 ping 通打印机。但第二台机器无法通过 Web 界面访问 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>
我还在某处看到说 CentOS 的 CUPS 需要 SSL 证书,这是真的吗?
答案1
CUPS 不需要 SSL 证书。您可以通过添加DefaultEncryption Never
到配置文件并重新启动守护程序来禁用 https。在较新版本的 CentOS(您没有指定正在运行的版本)中,Web 界面中有一个“允许远程管理”复选框,它将在端口 631 上提供远程 CUPS 管理页面访问。对于您来说,请浏览到:https://10.0.0.1:631/admin
这是我倾向于在新系统上部署的标准 CUPS 文件。
