Dear All, I guess, we all have to urgently apply workaround, following, say, this: https://gryzli.info/2016/10/21/protect-cve-2016-5195-dirtycow-centos-7rhel7cpanelcloudlinux/ At least those of us who still have important multi user machines running Linux.

Dear Experts, I know there are many HPC (high performance computing) experts on this list. I'd like to ask your advise. Almost two decades ago I chose to go with OpenPBS (turned down condor and other alternatives for whatever reason) for clusters and number crunchers I support for the Department at the university. It turned out to be not bad, long lived choice. At some point I smoothly

Dear All, Could someone give me some pointers. I never had it on CentOS 4,5,6. On freshly installed CentOS 7 ("development workstation" installation type with several extra things) when I log in as root in console I get this message: attempting to create directory /root/perl5 and indeed empty directory /root/perl5 is being created. (And my understanding is that that is done for every

Dear Experts, Could someone point me in the right direction: how can I disable hybernate/suspend in CentOS 7? I get workstations for graduate students with decent amount of RAM (32 GB), and for machines with large RAM I either do not have swap at all of have some small (4 GB) swap. As I remember from older manuals, one has to have at least twice amount of swap compared to physical RAM for

Dear Experts, Could someone recommend good Linux software RAID primer. It would be good if it has good coverage of monitoring and dealing with failures. I inherited a couple of boxes with big bunch of software RAIDs each, and I even may have some problems, but I don't want to bother anybody with specifics unless I really hit brick wall, not just my own ignorance. Thanks in advance for all

Hi, You can rebuild the RPM on a CentOS 8 box from https://dl.fedoraproject.org/pub/epel/7/SRPMS/Packages/s/squirrelmail-1.4.23-1.el7.20190710.src.rpm or https://dl.fedoraproject.org/pub/fedora/linux/releases/31/Everything/source/tree/Packages/s/squirrelmail-1.4.23-2.fc31.20190710.src.rpm and install the resulting RPM. For the source https://sourceforge.net/p/squirrelmail/code/HEAD/tree/

Hello Experts! I'm sure many of you run CentOS for some time already. My question is: is there some place that lists which of the most often used sysadmin commands are gone and what are replacements for them. Or what else one needs to do after successful installation. (in the past it was process accounting that was not enabled by default, but which gives you quite some handle in
