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

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?)

Universal server hardware platform - which to choose?
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

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

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,

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?

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:

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

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:

/bin/bash: /usr/bin/python2.7: Permission denied
>From my perspective:
# ls -l /bin/bash /usr/bin/python2.7

Storage - posibilities?
Hi all.
Currently I am administering a mail cluster in which messages are
stored on software RAID shared with NFS. There are several NFS
servers, every one of them exports a part of all mail files for a
specific frontend with postfix.
We are thinking about replacing these storage hosts with one solution,
maybe a storage array with appropriate disk space and I/O capacity.

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

11TB ext4 filesystem - filesystem alternatives?

I have a CentOS server:
CentOS 5.6 x86_64
2.6.18-238.12.1.el5.centos.plus

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

Running filesystem backup?
Hi all. I currently have a problem. I try to make a backup of a running /
filesystem to a second disc. I've read tha some people use rsync for it. I
mount the second harddisc at /mnt/hdb1 and issue a command:
rsync -vaHx --progress --numeric-ids --delete \
--exclude-from=asylum_backup.excludes --delete-excluded \
/ /mnt/hdb1
Then I shutdown the system, remove the first disc and try
