我希望能够访问 CUPS 网络界面的管理页面。
我可以访问该页面,并且可以浏览网站的大部分内容,但遗憾的是管理页面仍然被远程来源锁定。
我已经设置好了Allow from all
,也尝试了Allow all
所有地方,但仍然无法访问该页面。
我错过了什么?

答案1
我要做的是在下面这个区块以下标签</Policy>
:
<Location />
Order allow,deny
Allow localhost
Allow from 192.168.0.*
Allow from 10.0.*.*
</Location>
Listen 0.0.0.0:631
具体来说,对于管理员访问,原始配置通常具有:
<Location /admin/conf>
AuthType Default
Require user @SYSTEM
Order allow,deny
</Location>
为了创建一个合适的用户帐户,您只需要创建一个属于该lpadmin
组的用户(我建议您对管理部分确实需要某种身份验证):,sudo useradd -g lpadmin cupsadmin
然后设置密码。
也可以看看https://askubuntu.com/questions/387217/cups-admin-user-and-password-saucy
更新:以下内容应该作为一个起点,恰好修复@DavidGatti 最初提出的问题 - 它不像原始配置那样完整/细致,但可以重新添加策略配置。
但是,此配置确实不再使用 @SYSTEM 用户,而是接受任何“本地”有效用户。此配置的用例是在 docker 容器中运行 CUPS,因此最好避免要求任何“特殊”内容(除了具有密码的用户)来提供对 CUPS 的管理员访问权限。

答案2
如果您需要快速修复,而不需要技术细节,请使用此命令
sudo cupsctl --remote-any
sudo /etc/init.d/cups restart
答案3
由于我已在 Docker 镜像中将其配置为可配置(https://hub.docker.com/r/drpsychick/airprint-bridge),这是我使用的:
Listen *:631
在 cupsd.conf 中
和:
cupsctl WebInterface=yes
cupsctl --remote-admin --remote-any
# or
cupsctl --no-remote-admin
它重写你cupds.conf
并与杯子对话。
答案4
Listen 0.0.0.0:631
Port 631
我尝试了各种解决方案,但浏览器总是返回“连接被拒绝”消息,直到我像这样更改我的 cupsd.conf 文件。
