I am always very careful about reviewing the dependency list when using yum for installing or removing packages, but I can see how you might accidentally remove something you didn't intend to. -- Bowie

FW: Conga question
by Lopez, Denise 16 Jul '08

16 Jul '08

From: Lopez, Denise Sent: Wednesday, July 16, 2008 11:14 AM To: 'centos-bounces(a)centos.org' Subject: Conga question Hi all, I am trying to setup a high-availablility cluster using CentOS 5.2. All packages are currently up2date using yum. I would like to use it for automatic failover of Xen virtualized servers eventually. Right now I am just trying to create a new cluster with 2 Dell PowerEdge 1950 nodes. I have a separate luci server. One of the nodes connects just fine and the other one is hanging. On each node, a clustat displays that both nodes are online. I don't have anything else configured past the "Create a Cluster" page (ie. fencing, services, share resources). On the luci server, I keep getting the following error: "Unable to retrieve batch 640093076 status from hostname:11111: module scheduled for execution" Does anyone know what could be causing this. Port 11111 is open to all tcp on both nodes and I show an established connection with the node using netstat -antulp. For right now, the xend service is turned off on both nodes. Thanks in advance.

Xorg "intel" driver on 965Q lockup?
by Ken Key 16 Jul '08

16 Jul '08

Hi Folks, anyone out there successful in using the new xorg "intel" driver module on a 965Q-based motherboard with CentOS 5.2? The old "i810" and "vesa" work fine, I am looking for anyone else with experience with the new "intel" video driver in 5.2. The long of it: I have a customer's Dell Optiplex 745 (Core2 Duo 6300, 965Q chipset with integrated video) connected to a 19" NEC 1760V. Graphical installs of CentOS 5.2 completely locks the system when X starts. Text install succeeds and creates an xorg.conf using the "intel" video driver. Starting X causes complete machine lockup (no network - no ping, SSH dead) requiring a power cycle. This happens 95% of the time. I immediately assumed hardware problems but it passes memtest86 just fine and works with other video drivers. BIOS was 2.3.1 and I upgraded to latest 2.6.1 - no change. Unfortunately, a day of testing did not nail down a commonality of events to explain why the "intel" driver occasionally succeeds. Usually, it's after I've been in the BIOS menu so I suspect it is the video being in just the right state for it to succeed, but again it is not 100% reproducible. When the system locks up, no /var/log/X.0.log has been written or anything in the log files. I would like to build a kernel with sysrq key enabled to break into the kernel debugger on lockup, but I don't have the time as the hardware will be leaving soon. Switching to the "i810" or "vesa" drivers succeed 100% of the time so I have a workaround: a text install and manual edit of /etc/X11/xorg.conf to "i810". My app is old-school 2D so graphical performance is not a concern of mine. I've done searches of upstream Bugzilla, xorg, CentOS bugs, and the 'net in general and, while I find X display lockups with the "intel" driver, I do not find any complete system lockups. I'll file a bug against upstream but I'm trying to get a feel of what the scope of the problem is. I know there are folks using the "intel" driver successfully on other distros, so I'm trying to see if this is a CentOS problem, a RHEL problem, a Dell 745 problem, or just the one box I have (despite tests). Thanks for any feedback, Ken Key

need texlive & lyx-1.55 for Centos 5.2
by Paul Johnson 16 Jul '08

16 Jul '08

Today I installed the newest Centos I could find and encountered the old software problem. I couldn't find any third party repositories that have TexLive to replace tetex. Ii tried the Fedora version, but it calls for a different libpoppler. LyX in Centos is aged as well. As far as I can tell, rpmfusion will provide these things, but its confiig page still says 'not ready.' I followed quite a few blind alleys trying to work this one out. Got advice? I'm looking for an RPM based distro that is conservative on the kernel updates, but not so slow on apps. I don't want Fedora b/c the lifespan is too short. PJ ps. already tried EPEL and rpmforge. No Centos packages show up in rpmfind.net -- Paul E. Johnson Professor, Political Science 1541 Lilac Lane, Room 504 University of Kansas

settings up cheap a NAS / SAN server, is it possible?
by Rudi Ahlers 16 Jul '08

16 Jul '08

Hi all I want to look at setting up a simple / cheap SAN / NAS server using normal PIV motherboard, 2GB (or even more) RAM, Core 2 Duo CPU (probably a Intel 6700 / 6750 / 6800) & some SATA HDD's (4 or 6x 320GB - 750GB). My budget is limited, so I can't afford a pre-built NAS device. Can this be done with CentOS? I've been looking FreeNAS (which is built on FreeBSD), and it look like a great project, but since the hardware support in FreeBSD is limit, I'd rather use Linux for it. Has anyone done this? If so, please share a bit in your experiences :) -- Kind Regards Rudi Ahlers CEO, SoftDux Web: http://www.SoftDux.com Check out my technical blog, http://blog.softdux.com for Linux or other technical stuff, or visit http://www.WebHostingTalk.co.za for Web Hosting stuff

Help with iptables rule for blocking UDP port 53
by Sean Carolan 16 Jul '08

16 Jul '08

I would like to block all DNS queries that come from one particular ip address. I used TCPdump to verify that the queries were in fact, coming from this IP: [scarolan@server:~]$ sudo tcpdump -n udp port 53 and src 10.100.1.1 tcpdump: listening on eth0 11:12:17.162100 10.100.1.1.19233 > 10.100.1.61.domain: 14270+ A? server.domain.com. (32) (DF) Could someone help with the proper syntax for an IPtables rule to block port 53 udp traffic from this IP? I tried this rule but it doesn't work: -A RH-Firewall-1-INPUT -s 10.100.1.1 -m udp -p udp --dport 53 -j REJECT

Stopping a server not controled by service
by Robert Moskowitz 16 Jul '08

16 Jul '08

Miredo is run as a server from the command line: /usr/sbin/miredo The man page says the signal SIGTERM stops the server. How do I send SIGTERM to the server? Or SIGHUP, as I want to make a change to the config file. And once I get this as I want it, how do I run it at system boot?

RADVD and default IPv6 gateway
by Robert Moskowitz 16 Jul '08

16 Jul '08

the man page for RADVD says: radvd is the router advertisement daemon for IPv6. It listens to router solicitations and sends router advertisements as described in "Neighbor Discovery for IP Version 6 (IPv6)" (RFC 2461). With these advertise- ments hosts can automatically configure their addresses and some other parameters. They also can choose a default router based on these adver- tisements. But there is nothing I see in man radvd.conf that answers how hosts choose a default router, nor can I find anything else about this. Anyone know the answer or where to get the information???
