A LiveCD allows users to experience the desktop AND install the OS if
they like it
You just boot the LiveCD then click on the "Install Fedora" icon

If you're using Oracle JRE / JDK previous to 8u31 here are instructions on

Here, instructions on how to install Oracle Java8u40 on CentOS

But, if you're using the OpenJDK included in CentOS 6.6, it can be OpenJDK
7 or OpenJDK 8, which was included AFAIK as a technology preview, not the
default.

Here's more info on how to get OpenJDK8 in CentOS 6.6 if you don't have it

Thanks for the pointer Lamar.


 While this box doesn't qualify as 'vintage' yet, if you want to see the
 lengths to which some people will go you need to go lurk a while on the
 vintage-computer.com forums; there are people trying to do things as
 'interesting' as rebuilding an original PDP/8 (a 'straight 8') from
 scratch with just a collection of flip-chips, a blank wirewrap
 backplane, a vintage enclosure, and a set of schematics (and more time
 on their hands that I have!).


That is way too much for me. Yet, if I run across a Commodore 64 in a
dumpster, I'll surely open its guts and take its SI6581 sound chip for what
I wanted all my childhood and couldn't have: a Stereo SID cartridge. ;)

Of the 8bit years I've got a working C128D, and of the 16-bit age an Amiga
1200 (it works, but it's not hooked up, lost the scandoubler and hence it's
impossible to display its low-refresh modes in today's VGA monitors).
I've also got a working 4-way SMP monster, the ALR Quad6 (4x Intel Pentium
Pro 200Mhz) w 256MB RAM. But that thing is really a toaster.

 So what you're wanting to do, if you have
 the time and it's more for hobby purposes (or development purposes,
 even), is nowhere near as far-fetched as some of the things I've been
 reading lately.  (Long story, and way OT).


Basically I never had anything to do with blades, and since I have never
worked for big corporations (nor I plan to, unless one of my favorite tech
firms decide to hire me, and there's only 2 in that category ;), this
was/is the only opportunity of being up close with Blade technology.

It was fun already learning how it all works, and the hardware design. For
instance I thought before that the blades could operate by themselves even
with ethernet ports but that's not entirely true, without the interconnect
backplane and the comms blade (which I also found I have) that provides the
Ethernet ports, it's crippled.

Back to topic.

 It seems the only stumbling block for me so far is
1. Finding a 48V power supply
2. Learning the right polarity on the connectors in the back of the chassis
so I don't burn things down
3. Dealing with the UWSCSI issue, either by finding a cheap used UWSCSI
drive or buying an adapter (last night while searching about this, I
stumbled upon one Florida,USA store selling one UWSCSI to SATA adapter for
like $75, instead of the usual $150-$170 that is the minimum price you can
find on eBay or amazon).

In the end, if this exercise ends up getting nowhere. I'm gonna put the
blades for sale at a local auctions site, but first taking out the 8GB of
DDR2 ECC RAM which I can use in my Sun AMD Opteron box...

Thanks for the help -you and everyone who replied-, have a nice weekend!.

 Why would it uhh ave been tossed in the first place?...


I imagine it was something like: UW SCSI devices are nowhere to be found on
the local market -which I've been able to confirm by doing a simple search
on local auctions site and eBay wannabe mercadolibre-.

Probably their HDDs died and they asked for a quote to the local HP branch
and found the price quoted unacceptable (surely the local HP branch is
stocked on those drives, but being scarce and expensive to import on
demand, they surely save them to high-value customers with hardware
maintenance and support contracts... so if you're one of those high value
customers, surely you get replacement UWSCSI drives, if you're a tiny shop
maybe you're told sorry, we don't have any). But I'm just guessing,
painting a possible scenario.

Plus, importing used ones from eBay, which would have been the normal route
in this case, is, well, increasingly difficult down here. It´s hard to
explain the rationale of the irrational =
www.bbc.com/news/world-latin-america-25836208

Or perhaps someone got a kickback for buying a new server so the old one
NEEDED to be deemed obsolete. The awful truth about the realities of this
world. Follow the money. A third possibility is new admin doesn't have a
clue about the old kit, so he wants to get rid of it so he can buy
something simpler he does understand, and since he's the expert in charge
and nobody knows better -read the book Peter's principle-, they take his
word as gospel.

Of course I'm not accusing anyone of anything, just thinking aloud of
possible scenarios :).

I'm just happy of finding some nice kit for $0. ;)

Dumpster diving is a common practice, I do it often. I've been able to find
nice stepper motors and power supplies from tossed inkjet and laser
printers, for instance.

Dumpster Diving: beware, it's an addiction ;)

 Hello Fernando,

 This drive-technology was replaced 7 years ago and the cpu's are that old as

Yes, I figured that because of the HDD technology. I wasn´t sure of
the 7 years or 5 years but I figured it was close to that timeframe.
But you know, I´m typing this on a dual-core AMD Opteron purchased in
2008 so... old ancient hardware is the name of the game for me. ;)

 Better buy some 1HE Servers with an actual i3 and 500GB SATA-HDD for less 
 than the price of an old LVD-UW-SCSI drive. With these old blades you just 
 have excessive power-consumption, heat, low performance.

Yep, I agree with you that buying a SCSI HDD is a big no-no. Since my
current budget is zero, and I´ve picked up these blades from a
dumpster, buying a new blade is not an alternative, because I never a
had a budget to begin with... I´m just trying to get this to work just
for the heck of it and see if I can turn this gift into a CentOS
server, plus if I can make it to work it will be nice to have a spare
system to run some stuff isolated from my main server.

I think I´ve found a solution: there´s a daughtercard that apparently
includes a Mini-PCIe slot. In this, I figure I could add a half-height
card with USB 3.0 and/or SATA controller. If the blade BIOS will
recognize it and allow it to boot, that remains to be seen. This
hardware is (or was) enterprise grade and is way out of my league.
I´ve only built AMD Opteron servers myself, but in the PC tower form
factor. It´s the first time I´m looking at a blade from the inside.

So, is there a mailing list other than CentOS where I could find
people knowledgeable about the internals of these blades? Right now my
top priority is finding if I can hack a 48V DC power supply to the odd
(proprietary? or de-facto blade standard?) connector at the back of
the blade. I don´t want to pollute this list more with
hardware-related messages.

Thanks a bunch for replying!

There's no PSU in the box. I've got the enclosure as well! It's one of these

In the back all the blades are connected to an interconnect power regulator
board that goes to two large round prongs the kind used in
20 AMP 220/240 V AC plugs. But right now I'm 99% sure right now that this
works with 48VDC. The blades have tiny power regulator boards next to the

connector the markings say 48V for the white wire and 0V for the black

 What about networking?

 They either have shared networking (AFAIK) or there needs to be a
 module the lets you connect the blades to a switch...


Each of the two blades has its own riser board with 3 Broadcom Gigabit
Ethernet chips.
But there are no ethernet sockets in the blade itself. It seems the
ethernet signals go out of the back of the blade through the propietary
connector and then into an array of PC-ILO female sockets on the back

Maybe he was thinking of a rack enclosure full of blades. I forgot to say
that the enclosure can fit eight blades, the enclosure only had two. The
rest are dummy placeholders aka empty tin can blades. (which, btw, I think
are great for fitting a lot of RasPi(s) ;-).

Don´t fight guys, please. :))

I´ve found more info, I only had to read the sticker on the back of the
enclosure. It reads
48V DC. 62.5 AMPS max per shelf. Dual circuits (A+B) for redundancy

The dual male plugs marked POWER CIRCUIT A and POWER CIRCUIT B means
exactly that. The Beast has two independent 48V DC imputs, for redundancy.

But the positive and negative on each of the two not marked AT ALL and it
seems to me that the male round plugs protuding are totally reversible
(!?), so there´s a big possibility of frying everything if I get polarity
backwards...

Oh, Dear God of HP blades, we invoke you...

[CentOS] Old HP Xeon server blade with only SCSI HDD ports CentOS

[Fernando Cassia]

Hi there.

I got myself a pair of old Intel Xeon blades, which I plan to
repurpose with CentOS.
The model is : HP bl20p-g3 server blade

Manual
http://h18004.www1.hp.com/products/quickspecs/12322_ca/12322_ca.pdf

Now, the main problem with this hardware is that LVD UW SCSI HDDs are
hard to find and hella expensive if you find em (and of reduced
capacity).
Any of you know:

1. If there's any third party maker of any daughtercard offering SATA
ports? The main board of the system has daughtercard sockets allowing
for instance SFP ports
http://en.wikipedia.org/wiki/Small_form-factor_pluggable_transceiver
Seems to me that there'd be a small but interesting niche for this
kind of adapter.

2. If it's possible to use BootP for booting off a network drive?
I know there are some UWSCSI to SATA adapter daughtercards but those
sell for $250 which is way over my budget.

So, if you had one of these blades but not any UWSCSI HDDs what would you do?

Thanks in advance for any pointer. This hardware is too good to back
to the dumpster where I got mines from...

Certainly I see no technical problem with tcp wrappers.

approach seems to be hey this is old, I could add a few medals to my
professional resume and escalate a few positions up the corporate ladder if
I reinvent the wheel and redo this old working code in a totally different
way that breaks backwards compatibility and some third party code, so let's

any of the JVM languages without ever writing a single line of Java
code.

[CentOS] Unattended install of CentOS in a VM with given login/password?

[Fernando Cassia]

Is there a way to make CentOS install unattended, right from the boot
until I can SSH into it?.
I'd like being able to boot a new Virtualbox virtual machine right
from the CentOS ISO, and then from the Virtualbox host, ssh into the
brand new VM client and customize it using SSH shell scripts (SU, yum
install, etc).

Is there any way to tweak the ISO to specify unattended install and
the root password (to be later changed  after VM is installed).?

The main idea is turning this into a bash script so I can download
whatever new language and to the VM install automagically.

Thanks in advance.

 client side javascript programming is sometimes called AJAX.   Note that
 JavaSCRIPT is not Java, it only looks vaguely similar

I'm fully aware that Java != Javascript.
I was talking about the differences between client-side, desktop Java
apps and browser-based applets.

There's plenty of desktop Java based apps including Jitsi
(www.jitsi.org), Vuze P2P (vuze.com), Art of Illusion (Raytracer),
Sweet Home 3D (CAD), muCommander (JWS-enabled NC clone), jEdit, the
Netbeans IDE, FreeMind (mind mapper-productivity tool), Frinika (music

Or others like the burp LAN scanner or jHome home automation solution

JavaFX 2.0 and its open source release OpenJFX is client-side desktop
Java, and unrelated to applets or browsers.

In fact, if I use an ARCO RAID1 device (my favorite raid solution), it

everybody keep tagging it with experimental? And why do people
still think of it as a vulnerable one for production use? As a goal of

improvements on performance and keeping fixing bugs to make btrfs
stable, for instance, snapshot aware defrag, extent buffer
cache, rbtree lock contention, etc. This talk will cover the
above
---

From its web Liu Bo has been working on linux kernel development
since late 2010 as a Fujitsu engineer. He has been working on
filesystem field and he's now focusing on btrfs development.

RHEL 7 to get Btrfs support
http://www.h-online.com/open/imgs/45/8/8/4/6/5/1/43-6b4e69889ee000ca.png

RHEL 7 will support ext4, XFS, and Btrfs (boot and data)

Then you have SuSE:
https://www.suse.com/releasenotes/x86_64/SUSE-SLES/11-SP2/

With SUSE Linux Enterprise 11 SP2, the btrfs file system joins ext3,
reiserfs, xfs and ocfs2 as *commercially supported file systems*. Each
file system offers disctinct advantages. While the installation
default is ext3, we recommend xfs when maximizing data performance is
desired, and *btrfs as a root file system when snapshotting and
rollback capabilities are required. Btrfs is supported as a root file
system (i.e. the file system for the operating system) across all
architectures of SUSE Linux Enterprise 11 SP2*. 

https://blogs.oracle.com/wim/entry/oracle_linux_6_update_3

OL6.3 that boots up uek (2.6.39-200.24.1) as install kernel and uses
btrfs as the default filesystem for installation. So latest and
greatest direct access to btrfs, a modern well-tested, current kernel,
freely available. 

So, again, what´dya mean by less supported?. It´s in the mainline
kernel since February so with the adoption by RHEL 7, it´ll become
mainstream sooner rather than later...

Just my $0.02...

I was very pro-JFS... until I lost 10gig of very important data, and
back then (2002) there was no way to recover a JFS volume (the data
was in RAID, but some corruption ocurred and I lost the whole drive, I
mean, I ended up with a blank root).

Back in 2004 I asked one of the IBMers at the JFS team about it and he
had this to say:

-
IBM will continue to invest in jfs as long as we feel that our customers get
value from it.

Q: Will JFS be enhanced eventually with features from ReiserFS 4? (can it
be done without a complete rewrite?).

Possibly some.  Samba has been asking for streams support for a while,
and if reiser4 leads the way in an implementation that does not break
unix file semantics, jfs (and possibly other file systems) may follow.

-

Dunno if IBM did much to JFS after that... haven´t been following
their work wrt JFS...

Good news!.

My point is simple: I install the base config. I'm in text mode. I
need networking to work to install extra packages and begin setting up
my system, users, permissions, packages, etc. I have no problem doing
that manually AFTER I get the system up and running (and by running
I mean 'having network connectivity'). Having me edit config files
manually is an *annoyance*.

ONCE I get networking up and running. I have no problem editing config
files, because by then, with networking enabled, I'd have installed my
favorite tools (joe editor etc).

My point being that if the networking stack is part of the base OS
install, so should be system-config-network-tui

The installer switched to base mode/text install due to 'low memory'.
I just used the default recommendation by Virtualbox for Linux-RedHat.

Of course, in the grand scheme of things, it's not a problem. A
problem is a crashing kernel or buggy drivers.

My opinion after this experience is that it'd help for CentOS to
include system-config-network-tui as part of the base install. That is
my honest opinion about this experience. It'd have saved me from some
minor annoyance, albeit an annoyance nonetheless.

Just think the opposite: what would be the expense-damage of including
it as part of the base install?. Would it:

1. Break the OS
2. Make things easier for people who end up in the same situation I did.
3. Affect the balance of the Universe. ;)

Your choice. I think 2.

I agree in principle. But my personal experience led me to have static
routing on my home LAN.

If I enable DHCP I end up not knowing what IP address a 'new device'
just plugged into the network has, at any given time.

DHCP gives initial convenience, for long term hassle. (say you
want to telnet-in to your ethernet enabled media player)

 Sorry, no.  The only consulting special code I ever used was X25-uucp
 on SunOS 4.1.x

Thanks anyway for replying. I lose nothing by asking every former Sun
employee I run across. :))

I once built a small mini-ITX AMD x86 box mobo with riser card and one
intel quad-port Ethernet card I picked up real cheap on eBay. At that
time Solaris7 x86 was just released so I bought it  (I still have it
boxed), My plan was to use that system as a bandwidth manager and
traffic shaper for my home LAN.

Sun BwMGR looked like a great product (looking at the spec sheet at
least ;), all I remember is the Sun guy whom mailed me the CD telling
me you´ll have to use the command line to configure it because the
¨damn GUI¨ (sic) was coded for Java 1.x and Java 2 (at the time) had
issues with it so allegedly Sun was in the process of ´re-doing it´.
Go figure.

In the meantime I moved and lost the install cd, so I didn´t even get
a chance to try it.

Anyway... I guess nowadays I could do the same with CentOS and some
piece of FOSS...

At the time, the only comparable product was one commercial solution
for Linux and BSDs that was not only very expensive but also
license-locked to the mac address of the adapter(s) used which was
very annoying.

It s been so long ago that I forgot the name...

oh yes, thanks Google... ETBWMGR  they´re still around...
http://www.etinc.com/?p=69-ETBWMGR-Features

Well, Sun BWMGR was comparable to that. And apparently they killed
it... (then one wonders why Sun went under :-/, it wasn´t just
Microsoft -and they worked hard for that).

Afther Sol7 they bundled TCPIP QOS features  into Solaris (I wonder if
that code made it to OpenSolaris/OpenIndiana?) but I never understood
if the Sol9 QOS features could do the kind of traffic shaping on its
own without the cooperation of QOS aware routers on the LAN, as
SunBWMGR used to do.

Anyway, off-topic for this list... I know. Or not, if someone jumps in
with comments about traffic shaping on CentOS.. :)

To be honest, it never had any traction. At least not down here. And
it goes back to the Sun days, pre-Oracle.
Back in 2006 and 2007 Sun spent a lot in marketing and was down here
at Linux events with a Solaris booth or offering CDs etc... nobody
paid much attention to them...

I think the market for Solaris is the big corporations that use it to
run on high-end Sun/Oracle hardware (mostly Sparc), and those prefer
to pay to have a commercial grade solution with support. My guess is
that ORCL thought that they'd never get any ROI over 'free' Solaris,
nor any sizeable market share gain wrt Linux...

While some features like zones and zfs are interesting, Linux has also
improved as of late to fill some of those gaps...

Well, if you see it the other way around, Oracle' s -and SUSE' s and
any other competition that might come along- help puts RHAT pricing in
check...

In the end what matters is if Oracle's kernel programmers are any
better at fixing bugs than RHAT's and if their support responds on
time or not.

For us end users with no support contract, the more heads and firms
that are involved in kernel dev and linux support, the better, more
chance of getting higher quality software.

I see plenty of patches/fixes to the Linux kernel by Oracle employees...

if I start providing commercial services on top of a Linux box I'd
