view external: query (cache) denied

I have registered my nameserver  at registrar. I have properly updated the zone file in the server. But for some reason while checking the dig result the new name-server details were not showing correctly. I have checked the logs and got the following error.
view external: query (cache) denied
Reason : in the view external section in named.conf, the entry for my domain was commented. Once I un-comment, everything was correct.
If you got similar type of error, check your named.conf and also check whether named.conf and the zone file is ok using the following commands
named-checkconf
named-checkzone domain.com /var/named/domain.com.db

Using a Linux server to route packets between two private networks

Image
Reference: http://www.tecmint.com/setup-linux-as-router/ We want to route icmp (ping) packets from dev2 to dev4 and the other way around as well (note that both client machines are on different networks). The name of each NIC, along with its corresponding IPv4 address, is given inside square brackets. Our test environment is as follows: Client 1 : CentOS 7 [enp0s3: 192.168.0.17/24] - dev1 Router : Debian Wheezy 7.7 [eth0: 192.168.0.15/24, eth1: 10.0.0.15/24] - dev2 Client 2 : openSUSE 13.2 [enp0s3: 10.0.0.18/24] - dev4 Let’s view the routing table in dev1 (CentOS box): # ip route show and then modify it in order to use its enp0s3 NIC and the connection to 192.168.0.15 to access hosts in the 10.0.0.0/24 network: # ip route add 10.0.0.0/24 via 192.168.0.15 dev enp0s3 Which essentially reads, “Add a route to the 10.0.0.0/24 network through the enp0s3 network interface using 192.168.0.15 as gateway”.

PHP Fatal error: Class 'JFactory' not found

I have faced this issue in Joomla site and searched the forums but none of the forums including joomla did not give solution for me.

KVM & Qemu

QEMU is a powerful emulator, which means that it can emulate a variety of processor types. Xen uses QEMU for HVM guests, more specifically for the HVM guest's device model. The Xen-specific QEMU is called qemu-dm (short for QEMU device model) QEMU uses emulation; KVM uses processor extensions (intel-VT) for virtualization. Both Xen and KVM merge their various functionality to upstream QEMU, that way upstream QEMU can be used directly to accomplish Xen device model emulation, etc. Xen is unique in that it has paravirtualized guests that don't require hardware virtualization. Both Xen and KVM have paravirtualized device drivers that can run on top of the HVM guests. The QEMU hypervisor is very similar to the KVM hypervisor. Both are controlled through libvirt, both support the same feature set, and all virtual machine images that are compatible with KVM are also compatible with QEMU. The main difference is that QEMU does not support native virtualization. Consequently, QEMU has
