Hi, Are there any utilities or tools to look at historical data of Memory, CPU Utilization or IO activity on CentOS 6.4 or 5.9 Version? For example the how much the memory was consumed for the period of last six months. Regards, Kaushal

Hi Where can I find information on supported devices in qemu-kvm-ev? Does it support parallel port forwarding to the guest VM? Thx. P.S. cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)

My system is 7.2.1511. When I run "yum update", it wants to install about 900 packages total. Most are labeled just "el7". A few "el7_1" and a lot are "el7_3" or 7.3. None are 7.2. I'm not surprised when I see 50-100 packages needing an update. But 900? And none specific to the installed system? My last update, of 4 packages, was Dec 31, 2016. I

You need to add pop3.

Whether there is a version of the qemu-kvm with support for parallel port (passthrough). I need parallel port for Windows VM (security dongle LPT). I use on one host # /usr/libexec/qemu-kvm -version QEMU emulator version 2.3.0 (qemu-kvm-ev-2.3.0-31.el7_2.10.1) another host /usr/libexec/qemu-kvm -version QEMU emulator version 1.5.3 (qemu-kvm-1.5.3-105.el7_2.3) Both versions do not

CenOS 5.4 x64 I'm stuck at the command-line. I'm only familiar with the RPM command, but AFAIK, that cannot automatically resolve any dependencies when installing packages. Is there a command-line utility that I can force to automatically install all the dependencies for a particular package? I seem to remember a new UI was added recently that could, but I have to complete this from a

We have several "csh" batch scripts using "#!/bin/csh -v". It work fine, before Centos 5.5. After cenos 5.5, it will NOT execute and only list history. Anyone know why? Thanks.

Hi, Does a fix has already been made in the CenOS RPM repositories for this Samba remote execution code vulnerability, CVE-2017-7494? Thx, Bernard

We are currently running CentOS 5 update 4 on a Dell R910 server 16 cores/32 hyperthreaded with 64GB of memory. It is our main Oracle 11g DB server for one of our customers and is attached to an MD 3000 storage array. We are having a load averaging around 5 but see no swap in use, CPUs are pretty much idle and no I/O wait. We have Oracle dataguard turned on in transactional mode. I've checked
