问题 I'm trying get a list of CNAME records using PHP.

To get around this issue I used the following code (I could also use just the code in the catch block instead and it would

问题 I have a centOS virtual machine with 3 virtual hosts. It worked fine until this moment when I lost access to the dns server. Now the hosts can't be resolved.
