checkrpms checked the status of the packages on your system and 
produced the following output:
-------------------------------------------------------
$mailmsg
-------------------------------------------------------
If there are rpms which need to be installed, please log into
$perlvar{'lonHostID'} and run the following command

$checkrpms --update

If there are kernel packages to be installed, use

$checkrpms --update --install-kernel

Keeping your system up to date is very important.
Ensuring you are using up to date software is a prerequisite for a 
secure system.
