Replacing Multiple Servers with One
by Tim Evans 07 Mar '13

07 Mar '13

We are replacing four servers, running mail, web, ftp, and dns, respectively, with a single server to run all four services. The new server will have a new IP address. It seems fairly straightforward to redirect mail, web, and ftp services to the new server via DNS CNAMES, but I'm not quite sure about how to do the change for the DNS service itself. Is there a need to maintain the old DNS server's IP address during a transition, or longer? Via a virtual IP with the old DNS server's IP address on the new machine, perhaps? Or a second NIC with the old address? Or just have the router redirect incoming DNS requests? Thanks. -- Tim Evans | 5 Chestnut Court Linux/UNIX Consulting | Owings Mills, MD 21117 http://www.tkevans.com/ | 443-394-3864 tkevans(a)tkevans.com

Software RAID complete drives or individual partitions
by Chris Weisiger 06 Mar '13

06 Mar '13

I have been reading about software raid. I configured my first software raid system about a month ago. I have 4 500 Gig drives configured in RAID 5 configuration with a total of 1.5TB. Currently I configured the complete individual drivers as software raid, then created a /dev/md0 with the drives I then created a /file_storage partition on /dev/md0. I created my /boot / and swap partitions on a non raid drive in my system. Is the the proper way to configure software raid?

Centos 6.3 - unsupported video hardware
by Robert Moskowitz 06 Mar '13

06 Mar '13

I pulled one of my old OQO model 2 out of the junk bin and installed Centos 6.3 over Centos 5.3. The internal video does not work in graphics mode (text works fine), though a monitor attacked to the VGA port works fine. Although my intension is to use this as a portable test server, it would be nice if the video was available. How might I go about figuring out the Xorg magic to get it working?

Apache attacks - you can't stop them, or can you?
by Robert Moskowitz 06 Mar '13

06 Mar '13

So I have this nice, simple web server up running. Its purpose is to allow me external testing with HIP, and to provide some files for external distribution. Of course, there it is sitting on port 80 and the attacks are coming in per logwatch report. Examples from the report include: Requests with error response codes 404 Not Found //phpMyAdmin-2.5.1/scripts/setup.php: 1 Time(s) //phpMyAdmin-2.5.4/scripts/setup.php: 1 Time(s) //phpMyAdmin-2.5.5-pl1/scripts/setup.php: 1 Time(s) //phpMyAdmin-2.5.5-rc1/scripts/setup.php: 1 Time(s) //phpMyAdmin-2.5.5-rc2/scripts/setup.php: 1 Time(s) /muieblackcat: 1 Time(s) /myadmin/scripts/setup.php: 2 Time(s) /mysql-admin/scripts/setup.php: 1 Time(s) /mysql/scripts/setup.php: 1 Time(s) /mysqladmin/scripts/setup.php: 2 Time(s) /mysqlmanager/scripts/setup.php: 1 Time(s) Now these are only a few, though I am probably not being hit as hard as others out there. My question is: Is there a way to shut this nonsense down? Or because I am sending the 404, I am doing all that is reasonable to do? I am wondering that if this list starts getting long, that is a lot of logging and I probably don't need to log 404s?

Google Earth on EL6.x x86_64

Has anyone gotten 64-bit google earth to run on el6 x86_64? It dies almost immediately, complaining for lack of ld-lsb.so.3. Perusing user forums at google I see a few others with the problem, but no (working) solutions.

Im not so much concerned about the os not being on a raid system. I am really concerned about my data, music, pictures,docs, etc. I run a minimum os centos 5.9 install anyway so it would take long to reload the os if i had to. -----Original Message----- From: John R Pierce Sent: 3/5/2013 6:45 PM To: centos(a)centos.org Subject: Re: [CentOS] Software RAID complete drives or individual partitions On 3/5/2013 4:27 PM, Mark LaPierre wrote: > The question is why are you using raid at all? indeed. the primary justification for the "R" in RAID, Redundant, is high availability. having the OS on a non-raid volume completely violates this.

fencing nodes with drac under 5.9
by Adam Wead 06 Mar '13

06 Mar '13

Hi all, A recent update to CentOS 5.9 has broken my cluster's ability to fence nodes. I have two Dell's which are both fenced via their DRAC6 cards. The current configuration in cluster.conf for the fencing devices is: <fencedevice agent="fence_drac5" cmd_prompt="admin1->" ipaddr="192.168.251.11" login="fencer" name="ms1-drac" passwd="[omitted]" secure="1"/> After the updates, when one of the two systems comes online and starts the cman service, it will startup fencing. At that point it contacts the other node and reboots it repeatedly, never allowing the system to come back online. If I disable the cman service and renable it after both systems come back online, when cman starts up, it reboots the other and the process starts over again. Fencing with DRAC devices is not terribly well-documented, so I immagine there was something in the update that changed the way this worked. I originally used system-config-cluster to created the configuration file, but that had to tweak it adding the fence_drac5 agent manually because the configuration tool didn't support it. I also tried recreating the cluster with conga, via luci and ricci, but no success there either. Is anyone out there doing clustering with Dells and DRAC6 cards under CentOS 5.9? Or under CentOS 6 for that matter... I'm willing to update if it fixes this. thanks in advance, ...adam ____________________________________________ Adam Wead Systems and Digital Collections Librarian Rock and Roll Hall of Fame and Museum 216.515.1960 (t) 215.515.1964 (f)
