我有一个CUPS问题，让我疯狂。
我刚刚在RHEL 7.4（Maipo）上安装了CUPS 1.6.3。 我试图共享一台打印机，通常我会这样做，只需在printer.conf中添加一个打印机，并select“Shared Yes”即可。 出于某种原因，在CUPS启动后不久，它将“共享是”更改为“共享否”。
我不知道为什么。
printers.conf中的条目是：
<Printer Kyocera> UUID urn:uuid:1ef1dc65-ca04-3510-7364-0362c85b6859 Info Kyocera DeviceURI socket://192.168.25.20:9100 State Idle StateTime 1509470674 Type 6 Accepting Yes Shared Yes JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy retry-job </Printer> cupsd.conf文件是：

如果我做了“服务杯启动”，CUPS将启动，等待几分钟，然后用“Shared Yes”重新编写printers.conf改为“Shared No”。
我试过做“cupsctl – 共享打印机”，这似乎什么都不做。
在这个系统上没有X-Windows，它在远程networking上，所以我不能使用CUPSnetworking接口。 我确实使用wget来检查打印机的状态，但它说：
京瓷（空闲，接受工作，不共享）
……这是真的，不是我想要的。
有人可以告诉我我需要做什么来说服CUPS共享这台打印机吗？
编辑：使用SSH隧道，我能够访问CUPS用户界面，但进入“修改打印机”，并将共享状态更改为共享STILL不共享打印机。
