Cups, Centos 6 and the Internet
Hi. I have a Centos 6 server that use CUPS to print invoices, quotes, etc, but whe the ADSL get down the CUPS server stop connecting to the printers via LPD.
The ADSL gateway is a Cisco 800 series router provided by the ISP. The router is on and reachable but if no ADSL no printing.
What will be happening in the back? Centos 5 has a similar problem, but it prints, slow but prints.

Nobody knows why cups on centos 6 32 bits hangs when the ADSL goes down?
I mean if you're connection to the printer is entirely local then I can't see why it's happening. Obviously if you're connecting to your external IP then it makes sense, but I can't imagine you wouldn't know you were doing that. Perhaps I'd consider contacting Cisco about it.
Makes no sense, but happened two times yet. No DSL the CUPS goes crazy. And the Cisco is not working as switch. It can get fire and I am stll able to access the server but no printing.
Is it relying on any external DNS?
Do CUPS needs to do DNS lookups to print to a local networked printer with a fixed IP?
The server has external DNS, you know, to access the Internet. But locally everithing is refered by IP.
I hate printers. If I could figure out half the unexplainable issues they cause me, my quality of life would go through the roof.

Why do printers just... NOT WORK?!

You clearly have a different printer than I do
Does yours stop working at 5AM or something?
The hell still continues. When the DSL goes down the CUPS stops working and if I restart the service a connection not found error arises. I will go back to CentOS 5 this weekend to be back on peace.
Just thinking... Can I downgrade to the version used on Centos 5.9? Or better, downgrade the entire server?
