我无法连接 CUPS

我无法连接 CUPS

我按照 Debian Wiki 说明安装了 CUPS：

apt-get install cups-client cups-pdf cups

然后启动 CUPS 服务 ，/etc/init.d/cups start然后尝试连接到http://localhost:631/，但firefox还是w3m无法连接。

当我跑步时/etc/init.d/cups status，答案是：

通用Unix打印系统的状态：cupsd正在运行。

我的操作系统是 Debian Wheezy。

编辑：添加了日志和一些命令的输出

输出来自netstat -lntp：

到目录里看一下/var/log/cups。 CUPS 通常使用 3 个文件来记录消息：

  • 访问日志
  • 错误日志
  • 页面日志

例子

访问该目录将需要sudo.你可以这样做：

$ sudo head -5 access_log error_log page_log
==> access_log <==
localhost - ethan [24/Sep/2013:07:39:57 -0400] "POST / HTTP/1.1" 200 186 Renew-Subscription successful-ok
localhost - ethan [24/Sep/2013:07:53:57 -0400] "POST / HTTP/1.1" 200 186 Renew-Subscription successful-ok
localhost - ethan [24/Sep/2013:08:07:57 -0400] "POST / HTTP/1.1" 200 186 Renew-Subscription successful-ok
localhost - ethan [24/Sep/2013:08:21:57 -0400] "POST / HTTP/1.1" 200 186 Renew-Subscription successful-ok
localhost - ethan [24/Sep/2013:08:35:57 -0400] "POST / HTTP/1.1" 200 186 Renew-Subscription successful-ok
