Hi. We’re back. Well, not back exactly. We’d just like to take a minute to introduce you to somebody. Somebody that’s important to us.
We promised we’d let you know when we had news–and now we do. Opensource.com is our new adventure. It’s still sponsored by Red Hat, and still shining a bright light on the open source stories we’ve always sought out.
At opensource.com, we’ll be doing some things a little differently than we used to. We won’t be addressing as many technical topics–but we do hope to address more topics more often. We welcome contributions in the areas of Business, Law, Education, Government, and Life. We welcome new (and old) contributors.
And for those of you that were fond of our video contributions? Never fear. Our crack video team is fully involved.
So give it a click. Check out the articles. Sure, it’s not the same comfy digs you’d gotten used to, but pretty soon, it’ll feel just as homey. And that’s where we’ll be, for the next while.
Red Hat Magazine enjoyed a fantastic run. It’s launched careers, ideas, and helped publish–and promote–writers we dearly know and love. It gave us experience–and information–we can take to this newer, bigger venture. And now we’ve got a new venue–and a new name–to keep doing the kind of work we love. That kind of work and more.
One thing that has changed and–we think–for the better: It’s not just Red Hat’s magazine anymore. Opensource.com belongs to everyone. It’s a conversation-starter, a place for debate, and we hope you’ll come be a part of it.
And thank you. For subscribing, for contributing, and for reading–at RHM and beyond.
It’s that time of year again–the Red Hat Summit and JBoss World are fast approaching, and with them, Red Hat’s annual awards ceremonies. But first, we need nominations. And for that we appeal to our customers, readers, partners, and friends. That’s you.
Nominate that innovative business you worked with, or the admin who always has the right answers. Winners will receive free admission to Red Hat Summit and JBoss World, participation in exclusive events, and the admiration and accolades of their peers. Here’s the details:
Nominations are now open for the 2009 Innovation Awards, to be presented at this year’s co-located Red Hat Summit and JBoss World on September 1-4, 2009 in Chicago. » Read more

The dd command is one of those ancient UNIX tools that is extremely powerful, yet at the same time, the syntax can make it feel slightly archaic. A lot of seasoned sysadmins and developers still remember the first time they saw the dd command used by a bearded wizard. He might have used it to test the disk I/O, capture a disk image, or restore it.
In some ways, dd can seem like Old Spice–only the guys over 60 use it. But the younger generation should know that dd still has some tricks up its sleeve. In this article, we’re going to put a new twist on this old favorite and show how grandpappy really does know best sometimes. The new twist is to mix dd with Python and the Google Chart API to make a UNIX 2.0 mashup tool. (“UNIX 2.0” is a play on words for what happens when you change the original behavior of a tool like dd to make it do something a bit different.) » Read more
If the Satellite server is “connected”, then it will initiate outbound connections to ports 80 and 443 on the Red Hat Network (RHN) hosted service (rhn.redhat.com / satellite.rhn.redhat.com). Access to these hosts and ports should not be restricted to ensure correct functioning of the satellite system. If required, an HTTP(S) proxy may be used, by passing the “--http-proxy” option to the “satellite-sync” command.
If using a proxy server, Satellite will initiate connections to port 5222 on each proxy server connected. This is used for communications relating to the “OSA” service (also known as “Push to Client“). If using the OSA service, access to this port should not be restricted.
We’ve had some URLs of interest just sitting around the editorial desk. Now it’s Friday and time to share with you:
Are you sick of your ISP’s DHCP and want more control? Maybe you have a crusty Windows DHCP server that is about to blow up from the latest virus of the month or a series of “magic” GUI clicks gone horribly wrong.
Do a little spring cleaning, and solve your network problems with open source software. Setting up a DHCP server with Red Hat Enterprise Linux 5 or Fedora is a piece of cake. In this article we’ll go over the basics of setting up DHCP, doing basic troubleshooting, and finally setting up static mapping DHCP. » Read more
