XEN or KVM - performance/stability/security?
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?)

syslog-ng or rsyslog?
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,

samba4 - public share.
Hi,
I have samba4 working as PDC. Everything is working great, but when I'm
trying to set public share I can't set permissions to this folder which
allows to connect without auth. Is it possible to setup share like this
in samba4?
Please, help me with this issue.

Proper check of openssl usage in processes?
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

Monitoring bandwidth, latency, packet drop.
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:

NFS mount auto remount in case of problems.
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

Memcached - replication?
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

Strange behaviour when using sudo+sh+executable.
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

Virtualization - what do You recommend?
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

Update only of security vulnerabilities?
Hi All :)
What is the best way to get a list of available security updates?
I found several commands for that:
1) yum updateinfo list updates -q --security
2) yum list-security --security -q
3) yum --security check-update -q
Based on the sample output below I think I can use any of the three with
some awk to get a list of packages.
yum updateinfo list updates -q --security

What gui to use for syslog-ng logs?
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,

mbox files - can they be "compacted"?
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,

CentOS 6-6.3 -> no updates and security fixes?
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.
