Redhat Reports 90% Return Subscription Rate
jasonbowen writes "In this article from ZDnet, Redhat claims a 90% return subscription rate for its Enterprise line. Sounds like Redhat is doing just fine providing a quality product for people that want to pay the money for it." (And for people who don't want to pay money for it, too.)
You have scores of machines that you're managing through the free service? RHN allowed you to manage these for free (maybe the cost of a demo subscription or a single $60/year fee that you bounced from machine to machine). It put a load on their servers for both the rhn-applet, the up2date, and the package information that's stored there. There's a $20 update service now until EOL that you can buy.
You have many other options -- you can use yum, apt, synaptic to upgrade your machines. If you have all these scores of machines in a single facility you can create your own yum/apt repository and have the machines check each day via cron. If you want a centralized view of the state of your machines then maintain a database of each machines packages. Periodically check the repository against the package database and send an alert if any are out of date.
For example:
rpm -qa --query-format "%{name}\t%{version}\n"
For each machine store this information in a mySQL table. Then as new packages enter the repository, store that information inside another table. You can then select packages based on name between tables then inform the user that a package needs to be updated. Or count the packages that need to be updated. This will give you 90% of the RHN functionality. Won't be as pretty but it works.
Or you can pay RedHat for this service.
