Exactly the same problem there. I'm not sure if the drive is sick (I think it is OK, but I will try, ASAP, to find TEAC Diagnostics for it and run that) or if it is something in the Kernel or elsewhere in CentOS 5 that does not support the Teac drive. I have not run YUM update to update everything. Possibly I will do that tonight and let it go all night. Thank you! Lanny

WAY Off topic here, but if anyone's in the Augusta, Georgia area and wants to work as a web developer(css, html, flash, php, photoshop and the other usual goodies), we've got a job opening. If you like abuse, long hours, low pay, and lots of stress, we have the perfect job for you. -- During times of universal deceit, telling the truth becomes a revolutionary act. George Orwell

system-config-cluster problem
by Doug Tucker 30 Apr '08

30 Apr '08

I have a 2 node cluster that has been running for a year, and is still up and working fine. However, a yum update at some point broke system-config-cluster and it cannot load the management tab anymore, because it *thinks* the node is not part of a cluster, yet, all of the definions are there and I can modify them and save, but cannot publish the changes to the cluster using the tool. Has anyone else experienced this problem, or know what may be wrong?

Linuxtag 2008 - call for meeting
by Ralph Angenendt 30 Apr '08

30 Apr '08

Linuxtag 2008 in Berlin is coming closer by the minute (May 28th to May 31st 2008) - and we are going to be there. And so can you - either as a visitor or with us at the booth we have there! See <http://www.linuxtag.org/> for more information about the event. To coordinate this event, there is going to be a "Meeting" in the IRC channel #centos-social on the freenode IRC network (<http://freenode.net/using_the_network.shtml> for more information). The meeting will take place on Sunday, March 4th 2008 at 22:00 CEST (that's 20:00 UTC). Just connect to irc.freenode.net with an IRC client and /join #centos-social then. So if you want to be part of Linuxtag 2008: Be there on sunday! Or at least drop us a mail. As this mail goes to centos-devel(a)centos.org *and* centos(a)centos.org, please make sure that you only answer to both lists when you are subscribed to both lists. Best thing would be if you could subscribe to centos-promo(a)centos.org and discuss matters there. See <http://lists.centos.org/mailman/listinfo/centos-promo> for subscribing via the web. Cheers, Danke, Thank you in advance, Grüße, Ralph

f/oss routing solution?
by Rogelio 30 Apr '08

30 Apr '08

I'm looking for an open source router solution, and someone from the list recently recommended zebra (www.zebra.org). I haven't yet identified all my needs, but I'm guessing that it will do all my routing needs for a, say, class C set of IP addresses, particularly if I ever have to do anything BGP-related. Anyone have any pointers before I delve in? Or possibly a recommendation for another open source routing solution? Yeah, I know about Cisco stuff, but I'm hoping to limp along on a shoestring budget until I get a few more things in place, then I'll rethink everything.

I am going to try to swap the DVD readers, between my box and my daughters box, tomorrow morning, and see if the problem goes with the DVD reader that is now in my daughters box, when I install it in my box, or, if it persists in her box, with the DVD reader I now have in my box. Also, our Desktop boxes all have GNOME and KDE installed on them. The problem is *not* limited to GNOME. KDE also sees the DVD media as blank, when the FC6 Install DVD is in the drive.

Mark: Yes. That rpm has been installed. :-) However, I would like to eliminate this problem. The main user of that box is 7 1/2 years old and I can't give her root access or expect her to know how to use the CLI. She has been using Linux boxes for several years, but with a GUI. > I am a firm believer in command line usage, so I'm really not at all > clear on what the importance of being able to access the DVD via > Nautilus is.

No, and I believe that is a GOOD idea and I will post on the GNOME list and hope someone there has run into this and has a cure for this. Someone else here on the CentOS list replied to this thread, that he also has this problem, on an HP box. Also, I'm going to try Alan's idea and swap the DVD readers between the problematic box and my box and see if the problem moves with the DVD reader that is now in my daughters box, or, whether it is with that box itself. Thanks for the idea of posting on the GNOME list. I will do that! Lanny

That would be a PITA, however, I will *probably* do it, someday when I'm in the house alone and can concentrate on the task.
