– Yum-updatesd package installed by default with RHEL 5.X and 6.X to inform you with the updates , With some modifications on the default options found on the configuration files you will be able to receive the updates found on the machines
1# make sure the package is installed, enable it on boot and start the service
as root rpm -q yum-updatesd ; chkconfig yum-updatesd on ; /etc/init.d/yum-updatesd start
2# Open the main config file for the service with your favorite editor for me vim is the best
set the below parameters
run_interval = 172800 [ Two days ] this is cool for me , you can set the time you need emit_via = email email_from = " Sender mail address" email_to = " Recipient Mail address" do_update = no do_download_deps = no do_download = no smtp_server = 'You smtp_server:port'
3# take a look also at /usr/libexec/yum-updatesd-helper ” Python script” .. You can customize it also to add or remove some sockets if you want to ..
