up2date, rhn, and yum


Can someone please tell me:

1. the difference between up2date and "rhn", and

2. how to shut off that red circle with the exclamation point in it, in my upper Gnome panel.

I'm using yum, and I like yum. Can I completely do without all that is rhn and up2date? How do I do that? Can I use yum to remove those packages?

I've opened up the Desktop --> System Settings --> Server Settings --> Services application and unchecked, and shut off rhnsd for all runlevels, but that doesn't stop that little red pulsating circle! :)

As usual, I'm happy to update the LQ wiki if I can get these questions answered here. :)

Regarding question 1.

Here they are as I understand them
- rhn : are the servers that contain the updates
- rhnsd : is the daemon that checks for updates
- Red Hat Network Alert Notification Tool (the red circle) : Is the notification tool that shows when rhnsd finds updates.
- up2date : Is the Fedora official GUI update manager.

Regarding question 2
If you just shut down the rhnsd what will happen is that it won't search for updates anymore but I already notified the 'Notification tool' that there are updates.

You could either update your system (with yum or up2date) or shut down the notifier.

To shut down the notifier: Right click on the red pulsating icon and select "Exit" from the pop-up menu

My comments
I would not recommend shutting down the notification tool. It's a quite handy reminder that you have to keep your system up to date.

When you update from YUM (If it is correctly configured pointing to the right servers) the red pulsating icon will change to a blue check mark that does not pulsate.

I don't normally use up2date. I also prefer to run YUM from the command line. Sometimes when I am working on something and the notifier starts pulsating (quite irritating I agree) and I don't want to update right away I just close it as I explained.

If you use a modem connection It is better to update frequently, that way there will be less things to download.

If you leave your system on 24/7 you may even want to enable the yum daemon that installs updates every night.

Huh? Aren't yum and rhn completely unrelated?

Why would yum care what's going on with the rhn servers? I'm guessing that the "fedora servers" are separate and distinct from the "redhat servers", is that correct?

Well, those links that you sent, are saying basically the same as I explained.

Yum and up2date are NOT unrelated, they share some functionality (updating installed packages). Yum can do many more things, but the update functionality is similar to up2date.

After you update with YUM the rhnsd will identify that all the packages are up to date thus the Alert notifier will stop blinking.

Very few times, I have updated with YUM and noticed that the Alert notifier keeps blinking. I attribute it to the fact that an update has just been published to the rhn and it has not been replicated to the yum repositories. I update later and the notifier stops blinking.

So there you have it.

To update with yum run the following command as root:
Code:
yum update
Yum will actually tell you how many MB you will have to download.

Well, to be precise, the name of the service and the name of the tool have historical reasons. Red Hat Network (RHN) is not used with Fedora Core. Neither up2date nor yum access RHN. The world-wide mirrors, which carry copies of the download.fedora.redhat.com server, are not RHN. RHN was used as an option (together with an account) for Red Hat Linux and is used for Red Hat Enterprise Linux.

Of course they do -- right after you explained it to me, I went and updated/tweaked those pages on the wiki. Sorry for the confusion.

Thanks for the note "misc".
