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] -----------------------------------------------------------------

CentOS 6.8 and samba
by isdtor 23 May '17

23 May '17

Other than the original 6.8 release version 3.6.23-33, samba has not been functioning correctly for me under 6.8. The symptoms are that about 6-7 days after starting the server, users start complaining that they can no longer open documents on their share. Upon inspection, I find several, sometimes nearly a dozen smb processes owned by a single user, on top of those run under root. Stopping the service does not stop these processes. They are only killable with SIGKILL, and after that, a service restart does not result in a functioning service, i.e. connections are refused, which can be verified easily with smbclient. The only cure is a server reboot. And it is not the same user id every time it happens. Useful logs of any type are not available. I have tested -35 and -36, both show the same behaviour. This is a production server and I have no time for tinkering; downgrading to -33 and blocking samba updates is the only workaround for now.

How to enable the svm cpu flag inside a vm?
by Leonard den Ottolander 03 Apr '17

03 Apr '17

Hello, I'm trying to get the Android Emulator to run inside a kvm vm on CentOS-6. Apparently the latest Android Emulators cannot run without hardware acceleration so I am trying to get the vm to see the svm cpu flag. Host: $ grep model\ name /proc/cpuinfo | sort -u model name : AMD Phenom(tm) II X4 965 Processor $ grep svm /proc/cpuinfo | sort -u flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc rep_good nonstop_tsc extd_apicid pni monitor cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt npt lbrv svm_lock nrip_save $ cat /sys/module/kvm_amd/parameters/nested 1 I have tried copying the cpu options (Opteron_G3) in the host cpu configuration and setting the svm flag to either "model", "required" or "force" to no avail: $ ps waux | grep qemu qemu 7962 7.2 21.9 3722092 2680668 ?

I want to connect to a l2tp server from centos.
by Eliezer Croitoru 22 Mar '17

22 Mar '17

I have a server currently connecting to a pptp remote server. This server(lns\lac) has the option for pptp connections and l2tp connections. The l2tp connections are not using ipsec encryption at all. I have seen couple guides\tutorials on the internet: - https://raymii.org/s/tutorials/IPSEC_L2TP_vpn_on_CentOS_-_Red_Hat_Enterpris… - https://wiki.archlinux.org/index.php/L2TP/IPsec_VPN_client_setup But all the guides that I have found are using ipsec with "secret". On ubuntu there is a gui applet that helps setting these kind of connections up but I am working with a CentOS server and not Ubuntu desktop. If someone used l2tp the same way I want to use on CentOS 7 please give me some advice. If you have a guide which might help me I will be more then happy to see this one. Thanks, Eliezer

Outliner plugin for editor
by H 27 Nov '16

27 Nov '16

I am currently running not only Geany (on CentOS and on Windows) but also Gedit on CentOS, much of the use is as markdown-editors being a recent convert to this language. I would, however, also like to be able to essentially use it as an outliner - remember the old DOS outliners that were great for creating document outlines? It would have been perfect had I been able to fold and unfold sections of whatever markdown document I am working on in Geany or Gedit but sadly that does not seem possible... Nor have I been able to find a plugin for Gedit or Geany that would add that functionality. I do not want to have to use LibreOffice or something similar, it's too heavy and cumbersome. Hoping that someone can steer me to a solution!Thank you.

Fwd: CentOS on new Dell

I'd love to hear how's CentOS 7 support for E7470 hardware. Hi Milos, The Thinkpad T series and Latitude are *very* similar computers. They are both business "ultrabooks" with a 1600x1080 display option, nice keyboards (not "chicklet" style), a trackpoint and trackpad and RJ-45 builtin. I bought a Dell Latitude E7470 over the Lenovo for several reasons. One is this comment which is worth mentioning again: On Fri, Sep 30, 2016 at 11:58 PM, Gordon Messmer <gordon.messmer(a)gmail.com> wrote: > It's worth mentioning again that Dell is one of the companies doing the > development for the bits that don't work, and that those drivers are often > the ones that get Lenovo equipment going, too. Lenovo does not, to the best > of my knowledge, do any Linux development. Another reason is that I have heard about people having problems with Lenovo. Not just with software but with hardware malfunctions. I spoke to someone on the phone that had hardware problems with their new Thinkpad (although I suspect some of the problems could have been misdiagnosis by the user). After describing how nice the E7470 they're thinking about dumping their 1yo X250 and getting a Dell. As for the Carbon, that is a very different computer. The Carbon is an ultralight / thin Macbook-like machine with Windows so I have no advice for you there. I have not tried CentOS on the E7470 but I'm quite certain it would not work because I have tried the latest Fedora Live which is about 100 kernel revisions newer and even that doesn't completely work. Specifically, if I plug in an external display it freezes. My feeling is I need a newer display driver (and thus newer kernel). The only other issue I noticed was that wireless didn't work but it seems more like a glue issue and not necessarily a driver. Otherwise, suspend and everything else worked near as I can tell which is actually pretty impressive for a brand new machine. So, I am doing other things while this new E7470 ages like a fine wine. Or maybe I'll loose patience and just install Fedora and try a "vanilla" kernel package. Then maybe after a year or two CentOS 8 or whatever will run on it and then I can just run steady for 4+ years without getting pummeled by stupid updates and feature creep that you get with Fedora and Ubuntu or whatever the latest hot distro is. The E7470 is obviously a laptop of choice for business people. And that is the type of machine developers use. So chances of good compatibility are very high. You just have to give it time. I was watching Daredevil season 1 and they use Latitudes that look exactly like mine. And that was probably filmed in 2014. So the form factor at least has been around for a while which is good. Unfortunately I can't say the same thing about the show. Mike
