   年初的时候,在Asianux 3.0上尝试配置cups 1.2.4打印服务,遇到不少问题。见这里:[原]cups的windows-ext client-error-bad-request 故障 。这天,由于工作需要,再次处理cups 1.2.4。莫名其妙的是,这次同样的故障居然只处理一次,所以,特留下配置文件待以后参考。

一、关于使用SSL连接
由于只在局域网内使用,而且使用的人员不多,就没有考虑SSL加密链接,并把其禁用掉了。
但一直觉得奇怪,为什么使用http://ip:631/访问正常,使用https://ip:631/访问就没有响应呢?根据cups提供的升级说明,1.2.4版本应该是支持自动识别加密或非加密连接的。
查看日志文件:/var/log/cups/error.log,发现,如果访问https://ip:631/,就会有如下提示:

I [06/Oct/2008:17:03:16 +0800] Generating SSL server key...

决定等待试试,一直等。。。。等了5分钟后,终于出现:

I [06/Oct/2008:17:08:13 +0800] Created SSL server key file "/etc/cups/ssl/server.key"...
I [06/Oct/2008:17:08:13 +0800] Generating self-signed SSL certificate...
I [06/Oct/2008:17:08:13 +0800] Created SSL server certificate file "/etc/cups/ssl/server.crt"...
I [06/Oct/2008:17:08:13 +0800] cupsdCloseClient: SSL shutdown successful!
I [06/Oct/2008:17:08:47 +0800] cupsdCloseClient: SSL shutdown successful!
I [06/Oct/2008:17:08:47 +0800] Started "/usr/lib/cups/cgi-bin/printers.cgi" (pid=16245)

原来是我耐性不够,cups在后台使用cgi程序会自动生成SSL证书的。
(这时候,用top也没发现相关的运行进程,故原以为浏览器已经停止响应了)

二、解决windows-ext client-error-bad-request故障
这故障没仔细研究如何解决的,仅知道现在已经可以正常通过Windows连接到cups上,并正常打印。
贴出配置文件:
