Yes, those are the cards which target Windows and OS-X, but they work

They control 6 2TB WD Caviar Black drives, arranged as 5 drives in a

I need to track this error down because my understanding is that the LSI

[CentOS] Problem burning dvd's

2011-03-06 Thread Jimmy Bradley
  I have a question on burning dvd iso's, using k3b.
I have a sony dvd rw, and I've burned cd's with now problem, including
iso's. The problem I'm having is, when I burn a dvd iso, k3b says it's a
success, but then when I re-insert the disk, the drive tries to read the
disk, but the read/write light just stays on, and the drive can't access
the disk. Am I leaving a step out, or something? I burn cd iso's all the
time.

Aehm, OracleVM for Sparc is the Sun LDom (Logical Domains) software and does 
not work on anything but T servers. M servers use Dynamic Domains, a 
completely different technology. Containers/Zones or Dynamic Domains don't 
have a OracleVM name... 

Either way, Oracle counts Oracle VM (for x86/x64) as a hard partitioning 
technology when you use cpu affinity 
(http://www.oracle.com/technetwork/topics/virtualization/ovm-
hardpart-167739.pdf)... Its just another case where Oracle is favoring their 
own products with licensing.

Re: [CentOS] Gnu Screen - terminal issues

2011-03-06 Thread Sean Carolan
 The remote host's $TERM variable is in fact xterm.  When I connect to
 the screen session the $TERM variable is 'screen'.

 Are you running screen locally or remotely?

Remotely.  My work machine is a laptop, which is not powered on all
the time.  Hence I use a remote box as a jumping-off point, and run my
screen sessions there.

 Or you could write a script, scp it to the hosts you want to run it on
 (testing first, natch), and exec it:

   for host in hostlist; do scp myscript $host:.; done

   [fiddle around with tests or verification as necessary]

   for host in hostlist; do echo ** $host **; ssh $host ./myscript; done

Yes, I do this quite a bit.  But there are often times when I have to
do interactive work, running different commands on various hosts.

 As I mentioned earlier, dsh (distributed ssh) is a very powerful tool
 for running multiple remote commands.  Puppet, cfengine, and other tools
 may also be useful.

Yes, thank you for the pointers.  I'm familiar with both puppet and
cfengine.  The GNU screen sessions are mainly used during the build
process, before a server has puppet or cfengine up and running.

Adaptec is proud of their HostRAID technology that has a spotty
record with Linux compatibility. The manufacturer's descriptions
have led people to mistakenly think they bought a hardware RAID
card when in fact the RAID functions are implemented in software.
This approach has been dubbed fake RAID. It's not clear to me 
that this is a win compared to using the kernel's software RAID 
features.

 +1 for HAProxy; excellent piece of software.

It really depends on your needs, if you are building a production ops 
environment then the last thing that you would want would be an 
unsupported/home grown solution. You need to consider the potential risks 
involved in implementing a poorly understood / virtually unsupported solution 
that in all likelihood only you would understand vs. a standard solution with 
an SLA behind it and an upgrade path going forward.

A good reason why to run CentOS 5.4 (at least its kernel)?

Running remotely vulnerable Oracle Java which can be affected by a DoS
throug a web application?

The first google result for the above string takes me here:

http://bugs.centos.org/view.php?id=3582

Which in turn contains a reference that takes me here:

https://bugzilla.redhat.com/show_bug.cgi?id=484590

And it appears that this issue  was fixed with kernel version 2.6.18-164.

Roland's screencopy shows a java process rather than openswan.
