Hello everyone:
I tried following the instructions on this page to set up a VNC
server:
http://wiki.centos.org/HowTos/VNC-Server
I can telnet to port 5901 from the machine itself:

[6.2] Postfix not reading main.cf
Hello:
I just did a fresh install of CentOS 6.2 on a virtual server.
I am trying to configure Postfix but it does not seem to be
reading configuration directives from /etc/postfix/main.cf
Here is what I did to test it:
vi /etc/postfix/main.cf and set this directive:
myorigin = hello.world.com
postfix reload
postconf -d | grep myorigin
I get this output:
append_at_myorigin = yes
myorigin =

followup to request for centos C/W
just to follow on my earlier post, i have pointers to a couple
commercial C/W manuals for RHEL administration, but both of them use
an entire chapter discussing virtualization using Xen. i'm under the
impression that RH is firmly in the KVM camp (at least for now), and
that learning Xen on red hat/centos wouldn't be as useful as learning
KVM.
thoughts?

OT: How can I tell if a web site is now blocking IPs from my country?
I have always been able to browse, without any problems,
http://www.mobile-review.com/index-en.shtml but for the past 2 or 3
days, Mozilla Firefox just hangs "connecting to ...." How can I tell
if they have started blocking IP addresses from Colombia? I would
like to do that, before I post to the IPCop mailing list. I have my
IPCop box set up to do DNS Caching, so possibly something

Small proxy appliance hardware
I need to configure a small proxy appliance which doesn't require a lot
of CPU power. I'm looking for any warnings this group may have

chroot problem.
First, I'm trying to following along on a document on "SecurityFocus"
on "Securing MySQL: step-by-step".
I'm on step 3.8 "Test the configuration". I have my CHROOT directory
structure setup and the chrootuid is failing (haven't figured that one
out, yet). So, I simply tried a 'chroot /chroot/mysql' and got:

How to limit upload bandwidth for a KVM guest?
Hello:
I am using a CentOS server as a KVM host using bridged networking
for the guest servers.
I would like to limit the bandwidth available to a guest. I tried using
the tc command, but it is only limiting the download speed to the
guest.
Is there a way to limit the upload speed from the guests?
Thanks,
Neil

Virsh shutdown all command?
Hello:
Is there a command in virsh to shutdown all domains?
I can do one at a time, but that is untenable for a large
number of domains.
Thanks,

acrobat reader for x86_64?
Adobe doesn't seem to have acroread for x86_64 linux, or at least I don't
see it anywhere.
Anybody know otherwise?
Evince and other tools work pretty well, but I have always liked having
the "real thing" around for those occasions when they don't.

Slightly OT: FakeRaid or Software Raid
I have had great luck with nvidia fakeraid on RAID1, but I see there are
preferences for software raid. I have very little hands on with full
Linux software RAID and that was about 14 years ago.
I am trying to determine which to use on a rebuild in a "standard"
CentOS/Xen enviroment.
It seems to me that while FakeRaid is/can be completely taken care of in

Sparc?
My 12 year old wants to learn more about servers and has memorized a lot of commands like ls, chmod, du, etc.
He wants to have his own domain and server on the web and I have enough Static IP's, so why not foster this interest.
I have an old ultra sparc 5. Are there any CentOS versions that support Sparc?
Or recommendations? I know OpenBSD does, but I am more versed in Solaris and versions

Apache/Cluster issue -- Single public IP address
I want to set up a cluster that is used for web hosting (RHCS cluster). Recently,
I experimented with a 2 node cluster and was able to run it successfully. However,
I have started facing some issues with Apache, which I had configured as a service
using the Cluster configuration tool. To do this Apache needs a floating IP address.
This address is in addition to the network interface IP address.

software installation - good practice
Howdy,
I tend to try out many open source apps/packages - games, editors to
media tools. I have a bad habit of downloading and extracting source
in the /var/tmp directory and then doing configure-make-install
process. I am not sure of best practice (good practices) to be
followed when installing any software. For example how and where to
keep the src. Any comments and/or resources would be really

Hi All:
I have a rather annoying problem with rndc which I have not been able

KVM Support for Windows Server 2003 32 bit ready for production?
Hello:
I am wondering if KVM is ready for production
for running a Windows Server 2003 32 bit guest.
According to the RHEL 5.4 virtualization guide,
there is supposed to be a virtio-win yum package,
but that was not released. Instead, it looks like
that is only available for RHN subscribers.
Also, I saw this posting on the CentOS list:
