Joomla Drupal Update and Install from URL failures

I need some help on a problem.

The problem I'm having is on RHEL 6.5 with the following versions (all php, mysql, and apache versions are current)
--Drupal 7.28
--Joomla 3.3.0

Errors when trying Updates

--Error on Drupal - Failed to get available update data for one project.

--Error On Joomla - 0 Couldn't resolve host 'update.joomla.org'

Example Error when trying Install from URL Errors

--On Drupal - HTTP error 0 occurred when trying to fetch http://ftp.drupal.org/files/projects/token-7.x-1.5.tar.gz
Unable to retrieve Drupal project from http://ftp.drupal.org/files/projects/token-7.x-1.5.tar.gz.

--On Joomla - 0 Couldn't resolve host 'www.elitewebdev.com'

I have found simmilar problems in my searches but no resolutions. Any help is appreciated.
