Memory vs. Display Card
by Rick 28 Oct '25

28 Oct '25

Since memory has become quite cheap lately I decided to move from 2 GB to 6. When I installed the memory every thing was fine until I went to run level 5. At that point the screen turned to garbage and the system froze. Is there a way to fix this so I can use the memory I bought? Do I need a new display card?

SSD for Centos SWAP /tmp & /var/ partition
by Keith Roberts 03 Sep '25

03 Sep '25

Has anyone actually used a SSD in a Centos setup? My little experiment with a s/h WD drive for /tmp and SWAP partitions kicked the bucket on Wednesday, when the poor WD drive caught the click-of-death. It was a s/h drive to start with and lasted about 4 months. But that was without the /var/log/ partition being written to it, as I mounted that back onto /var/log from the original drive. So I had to install another (WD) drive, and repartion it and rebuild my RPM package database, from the backed-up Packages file. That seems to be all OK now. I'm wondering if it would be a good idea to use a new SSD for moving all the disk i/o to, that Linux likes to do so often. Plus putting SWAP onto a decent SSD should speed things up somewhat. Here's a short video of a laptop fitted with a SSD drive booting macOS, compared to a similar laptop booting from the standard HDD. The laptop with the SSD boots and loads some apps in 28 seconds. The other one takes twice as long. http://eshop.macsales.com/shop/SSD/OWC/Mercury_Extreme_Pro_6G/?utm_source=t… Kind Regards, Keith Roberts ----------------------------------------------------------------- Websites: http://www.karsites.net http://www.php-debuggers.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------------

Mail Merge data to a pdf file by overlaying the data on the image
by Gregory P. Ennis 07 Jun '15

07 Jun '15

Everyone, I am looking for a utility that I can use to do a mail merge of data to a pdf image file. The image file does not have any active fields, but will be just an image file. I would like to overlay names addresses etc. We currently do this with a pcl file by just overlaying the data with pcl print positions. However, in order to get the pcl file from an original pdf file we have to use gimp to convert the pdf to pcl file, and we always lose a little resolution. I was wondering if anyone knows of a utility to perform this function without first converting the image to a pcl file. Thanks, -- Greg Ennis

heavy IO load when working with sparse files (centos 6.4)
by Ron E 31 Mar '15

31 Mar '15

Dear List, We have noticed a variety of reproducible conditions working with sparse files on multiple servers under load with CentOS 6.4. The short story is that processes that read / write sparse files with large "holes" can generate an IO storm. Oddly, this only happens with holes and not with the sections of the files that contain data. We have seen extremely high IO load for example copying a 40 or 80gb sparse file that only has a few gigs of data in it. Attempts to lower the io priority and cpu priority of these processes do not make any measurable difference. (ionice, nice) This has been observed with processes such as: cp rsync sha1sum The server does have to be under some load to reproduce the necessary conditions. The cases we have seen involve servers running 10-30 guests under kvm. Load is in acceptable norms when the processes are run, such as load avg 5-15 on a 24 core (12 core with HT enabled) server. We also verify before starting such a process that the spindle with the file we're working on is not being unduly hammered by another process. These servers have one hardware raid controller each (Dell H700 controller with write cache enabled) and multiple raid arrays (separate sets of physical spindles). Interestingly, the IO storm is not limited to the array / spindles where the sparse file resides but affects all IO on that server. We have looked extensively and not found any account of a similar issue. We have seen this on configurations that are 'plain vanilla' enough to think that this is not something specific to our environment. Wondering if anyone else has seen this and if any suggestions on gathering more data / troubleshooting. We wonder if we've found either a raid controller driver issue, an OS issue or some other such thing. What seems to point in this direction is that even with ionice -c3 which should prevent the process from using IO unless the storage is idle, an io storm which appears to saturate the entire raid bus on a given server can occur. Thanks in advance.

Centos 6.4 on Xserve, IPMI error
by Arno B 31 Mar '15

31 Mar '15

Hello! I'm trying to install Centos 6.4 64 bit on this Xserve: http://www.everymac.com/systems/apple/xserve/specs/xserve-intel-xeon-2.8-ei… I got a bootloader from: http://blog.christophersmart.com/2009/07/23/linux-on-an-apple-xserve-efi-on… as none of the official Centos releases (full, minimal, network 64 bit) boot on this machine. They all crash when loading the bootx64.conf. I have built a USB stick with a working bootx64.efi, grub.cfg, together with an initrd and a vmlinuz from the isolinux folder. These seem to get me into booting a kernel until something called IPMI is starting to throw errors at me: Console: switching to colour frame buffer device 128x48 fb0: VESA VGA frame buffer device ipmi message handler version 39.2 IPMI System Interface driver. ipmi_si 0000:09:00.4: enable device (0002 -> 0003) ipmi_si 0000:09:00.4: PCI INT C -> GSI 16 (level, low) -> IRQ 16 ipmi_si: Adding PCI-specified kcs state machine ipmi_si 0000:09:00.7: enable device (0000 -> 0003) ipmi_si 0000:09:00.7: PCI INT D -> GSI 17 (level, low) -> IRQ 17 ipmi_si: Adding PCI-specified bt state machine ipmi_si: Trying PCI-specified kcs state machine at mem address 0x90841000, slave address 0x0 irq 16 IRQ 16/ipmi_si: IRQF_DISABLED is not guaranteed on shared IRQs Using irq 16 ipmi: Found new BMC (man_id: 0x00003f, prod_id: 0x0003, dev_id: 0x20) IPMI kcs interface initialized ipmi_si: Trying PCI-specified kcs state machine at mem address 0x90840000, slave address 0x0 irq 17 Refined TSC clocksource calibration: 2792.999 MHz.

RH developer toolset
by Jerry Geis 13 Aug '14

13 Aug '14

I saw an article this morning about the RH developer toolset. basically it includes a couple of packages like PHP python mysql (etc) that are later packages than that included in the released version like a 6.4 for example. So instead of php 5.3 with patches it would be php 5.4 and so on. That is great for a couple packages - but what about more up to date libraries like glib. 6.4 is way behind on glib. Like a couple years behind. Are there any plans in the "toolset" to update core libraries also? Thanks, Jerry

Create Virtual Machine via HTTP or FTP
by cbulist＠gmail.com 08 Jun '14

08 Jun '14

Hi, I'm trying to create a Virtual Machine using Network Install mode (I tried HTTP and FTP). The HTTP/FTP server where the installation files are located is the Host Machine. The URL that I'm using is: http://192.168.1.104/inst and the Automatic detect option detects the OS without problem. When the installation starts I got an error: Unable to retrieve http://192.168.1.104/inst/images/install.img I tried different path but I always get the same error. The host machine is a Centos 6.2 (2.6.32.-220.el6.x86_64) I really appreciate any help with this problem. Thanks in advance,

I am currently using, as a server, a workstation computer. It was built with a gigabyte motherboard and has 8G ram and a 1000G Sata 3 drive. It is accessed with ssh and runs an ftp server, a web server and a samba server so my wife can back up her pc to it. It is running behind a router. This computer more than meets my needs as a lightweight server except the hardware is dying and I want to replace it. The question in my mind is: should I just buy another workstation class motherboard and duplicate what I already have or buy a motherboard which is intended to be used as a server? Thank you, Joe

Centos box and Cisco 3750 VLAN's
by Boris Epstein 03 Jun '14

03 Jun '14

Hello all, I have a CentOS box that has a NIC (eth0) on which I defined 4 VLAN's (counting the NIC itself): eth0, eth0.1, eth0.2 and eht0.3. Initially the Cisco switch was not partitioned into VLAN's which means that the only VLAN running on it was the default one (VLAN 1). I have then played with VLAN's a bit on the switch and at this point have two: VLAN 1 (which is default and can not be deleted) and VLAN 3. The CentOS box is plugged into a trunk port on VLAN 3 which by virtue of being a trunk should belong to all VLANs. However, this does not seem to work as expected. What I get is the following: 1) eht0 does not come up at all. ifup eth0 Device eth0 does not seem to be present, delaying initialization 2) eth0.3 comes up fine. 3) Other VLAN's do not come up. No error messages, just never show up. Any insight into this would be most welcome. Primarily, I fail to understand why all those VLAN's came up on VLAN 1 and why now even VLAN 1 does not come up - even though the trunk port the device is plugged into is supposed to be a member of all VLAN's. Thanks in advance. Boris.

Newer version of ffmpeg for EL6?
by Lists 03 Jun '14

03 Jun '14

We're trying to build a rich media website, and will need to re-encode the video content with ffmpeg. Unfortunately, the ffmpeg version that comes with the most common repos are rather out of date. As in 0.6.5 vs 2.21 being the most current version. However, ffmpeg looks to be a pretty thorny thing to compile with all the options we need. It appears that the FFMPEG with rpmfusion for Fedora is pretty current, 2.1.4. Is there a repo out there that anybody knows of that has a relatively current version of ffmpeg out for Centos 6? Thanks in advance, Ben

nodejs, epel, SCL

traffic distribution not happening in centos 6.5
by Varun Sharma 02 Jun '14

02 Jun '14

Hi, I am experimenting with libnetfilter_queue. libnetfilter_queue is a userspace library providing an API to packets that have been queued by the kernel packet filter. I am using sample code(nfqnl_test.c) available on netfilter.org. I have generated two binaries (queue0 and queue1) using that nfqnl_test.c sample code. These binaries are working as per expected behaviour in case of Centos 6.2 but with Centos 6.5 only one queue is receiving network traffic.

30 May '14

Until recently, I had a 32-bit machine with one monitor running fedora. The later editions of fedora didn't like it, so I switched to CentOS. Now I have two 64-bit machines and two monitors and a CenturyLink router. Also a KVM switch that I have not taken out of the package. My main machine has two video connections and two ethernet connections, eth0 and eth1 . I've never had more than one machine or more than one monitor before. I'd like to be able to use both monitors at once on my main machine. I'd like to be able to switch one monitor between machines without too much trouble. I'd rather not where the pins out. KVM will do this, right? KVM is transparent to the computer, right? My secondary machine sometimes runs Windows, so I'd like it not to have its own global IP address. My first thought would be to connect it directly to one of the ethernet ports on my main machine. How do I go about this? The answer I am expecting is one or more links to tutorials or the like. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "SCSI is NOT magic.

OEM suggestions
by m.roth＠5-cent.us 30 May '14

Hey, folks, I'm working on finding some new compute nodes. What I'm looking for is a 64 core box, with room enough for a lot of RAM. I can get it from Dell, or HP (bleah! a 4U box), but I need to have three quotes, y'know. We've gotten a lot from Penguin in the past, but they're all Supermicro, and we've had a *lot* of problems with the 64 core boxes, so I'm looking for another vendor. Suggestions? Recommendations? People to run the other way from? (Sun/Oracle is down there *under* "none of the above"). mark

Tracking Open Ports
by Eric Falbe 30 May '14

30 May '14

Hi All, I was wondering if anyone knew of a way to notify or log when a specific remote port is openened? I have an old LDAP server that I am looking to get rid of, but there is still a few queries reaching it. The sytem authentication is setup correctly (as is Postfix), so I am thinking there must be some script or program that is setup to query the older LDAP server. I tried using lsof -i|grep 389, but I am not quick enough to get results before the socket is closed. Is there any program or script I could write to detect when this socket gets opened, and what PID and/or program owns it? Thanks, Eric Falbe
