Thanks for the links, they are very informative. So as I see currently the only way to check if there are any security updates available for Centos is to parse the errata info sent by email to Centos Announce? :D Does anyone have another solution implemented? :) Any help will be very appreciated :) BR, Rafal. 2015-04-08 18:15 GMT+02:00 Jonathan Billings <billings at negate.org>: > On

Hi all. I am currently designing a server room. I would like to be able to draw a 2D (in the future 3D) project. Do you know any tools? Which one can you recommend? Best regards, Rafal Radecki.

Hi all. I am currently building a small test cloud based on Eucalyptus 2.0.3 and CentOS 5.8 x64. I have a choice which hypervisor to use: KVM or XEN. KVM is the default in CentOS 6 but I have read also many good things (for example PV guest machines, isolation between Dom0 and DomU) about XEN. Key factors from my opint of view are: - stability (which one runs more smoothly on CentOS?) -

Hi all. I am working for a hosting provider in Poland. We are currently searching for an universal, extensible hardware platform which we would like to use in our server infrastructure. The platform should have: - possibility to install up to 32GB of RAM and at least 4 slots for it; - at least 6 SATA ports; - the possibility to use SAS disks; - at least one 1Gb/s network interface and the

Hi All. I've used syslog-ng for some time. I like it. I have a project in which I need to choose a central logging solution. What are your experiences with rsyslog? Is it more complex to setup than syslog-ng? Or maybe does it have some additional features? I am also thinking about using some gui tools for log parsing and graphing. May be proprietary/paid. Any suggestions? Best regards,

Hi All. I have a setup in which I have two servers serving nfs share. The nfs service is made highly available with pacemaker. When the primary server goes down the secondary starts nfs service. Service IP is floating between servers but they have NO "shared" storage/filesystem so NFS state/connection information in case of failover is lost. I have two clients. When the failover from

Hi All. I plan to use virtualization in my production environment. I plan to use one of the following options: - KVM; - VMWare Esxi; - VMWare Workstation. I plan to install Windows 2008 as a guest. I want to use something like LVM snapshots for backups. Stability is also very important, the guest will be used as a production server. Which option could You recommend and why? Thank You very much

Hi All :) I need to check and possibly update openssl on my fleet of servers. I would like to avoid reboot if possible. I think that I can: - update openssl version with yum - check all daemon processes which are constantly running in the os, for example for sshd something like ldd `which sshd` | awk '/\// { print $3 }' | grep crypto | xargs strings | grep -i openssl to verify if the

Hi all. I am currently thinking about monitoring a network link (bandwidth, latency, packet drop). I have a centos server which is connected to providers network through a switch. How to test the link? Should I: - use ICMP to ping gateway and collect staistics of time/packet loss/etc. - use software like here: http://www.cyberciti.biz/faq/linux-unix-windows-monitor-outgoing-bandwidth-latency/

Hi all. I am thinking about installing memcached with replication, I've found http://sourceforge.net/projects/repcached/files/repcached/2.2.1-1.2.8/ but it is for 1.2.8, and for Centos 6.3 memcached is in version 1.4.4. I do not want to use client side "replication" (writing to two memcached nodes at the same time) and haven't found other solution. Are there any good, protocol

Hi All. I am trying to install some software. Part of its installation is an invocation of command similar to: # sudo -H -E -u postgres /bin/bash -c /usr/bin/python2.7 /bin/bash: /usr/bin/python2.7: Permission denied >From my perspective: # ls -l /bin/bash /usr/bin/python2.7 -rwxr-xr-x. 1 root root 960376 Jul 8 2015 /bin/bash -rwxr-xr-x. 1 root root 7136 Oct 11 2015 /usr/bin/python2.7

Hi All. I have an environment in which I would like to implement a GUI for parsing syslog-ng logs from operating system, application servers and databases. I've heard that Splunk is a good tool but its quite hard to learn. Are there any valuable alternatives? What are you using and why? Best regards, Rafal.

Hi All ;) Is there an option to compact large mbox files from the shell? I did not find anything in google, I have some very large constantly updated mbox files and would like to know if they can be made smaller with any tool. AFAIK mutt does such operation when for example an email is deleted but I am curious if there are other options. BR, Rafal.

Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes

Hi All. I have two servers ("master" and "slave") with a replicated gluster volume. Recently I've had a problem with slave and gluster does not work on it now. So I would like to: - stop and remove current volume on master (on slave it is not accessible); - stop gluster software on master (already stopped on slave); - remove gluster software on master and slave (previous

Hi All. I have installed Citrix XenServer. It's Linux-based virtualization software. Could anyone propose a good way to make backups of virtual machines (Linux/Windows) in it?

Hi All. I have a CentOS server: CentOS 5.6 x86_64 2.6.18-238.12.1.el5.centos.plus e4fsprogs-1.41.12-2.el5.x86_64 which has a 11TB ext4 filesystem. I have problems with running fsck on it and would like to change the filesystem because I do not like the possibility of running long fsck on it, it's a production machine. Also I have some problems with running fsck (not enough RAM, problem with

Hi All. I've found: This directory (and version of CentOS) is depreciated. For normal users, you should use /6/ and not /6.3/ in your path. Please see this FAQ concerning the CentOS release scheme: http://www.centos.org/modules/smartfaq/faq.php?faqid=34 If you know what you are doing, and absolutely want to remain at the 6.3 level, go to http://vault.centos.org/ for packages.
