New CentOS7 Install Yum will not work

Hi Everyone:

I have been fighting this all morning. I did a new (several) installs of
CentOS7. Yum will not update the system. I have disabled ipv6, set
yum.conf to use IPv4 only, disabled firewalld, disabled selinux, used both
static ip and dhcp for network connectivity. I can ping any where on the
Internet, including the mirrors, DNS works and ensured the base URL line
was uncommented.

DNS caching is not working on CentOS

Hi All:

For whatever reason I can not get dns caching to work on any of my
centos boxes. Running Centos 5 and 6. Any thoughts on why these will
not run? The services start fine but when telling to perform a dig
using itself as the resolver the queries fail (See below).

Any help would be appreciated.

Hi All:

I am trying to resize a centos (5.2) VM drive. I use VMware and I have
increased the size of the drive by 40G. I am running resize2fs on
/dev/sdb1 (which is my root partition) but when I do I get this error:

[root@centos ~]# resize2fs /dev/sdb1 120G
resize2fs 1.39 (29-May-2006)
The containing partition (or device) is only 19970795 (4k) blocks.
You requested a new size of 31457280 blocks.

How can I change the block size?

I have also tried to use gparted live cd but it will not allow me to
increase the size even though it sees 40g of unused space.
