Just want to let you guys know that, although it may have been around
for a bit, bringing Xen back to CentOS is awesome and I really
appreciate it.  I was very disappointed when RedHat dropped support as
Xen is awesome.

[CentOS-virt] Can't create new Xen domains using libvirt on CentOS 6.5

2014-01-28 Thread Jens Pelzetter
Hello,

we have a strange problem on a fresh install of CentOS 6.5. On the
server we want to use Xen to host paravirtualised guests (the system has
no hardware virtualization support). To manage the domain we would like
to use libvirt. Xen and libvirt are set up as described here:

http://wiki.centos.org/HowTos/Xen/Xen4QuickStart
http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt

When we try to create a new domain this does not work. In

2014-01-28 Thread Jens Pelzetter
Thanks for pointing me to xm dmesg. That was the missing part. The
server has one of the AMD CPUs affected by this:
http://lists.xen.org/archives/html/xen-announce/2012-06/msg2.html

So we had to add allow_unsafe to the boot line. Now Xen works fine.

Re: [CentOS-virt] Hey

2014-01-28 Thread Robert Dinse

  I've used both Xen and KVM and at least in benchmarks of applications I
did here I didn't see much difference and since KVM is natively supported by
RedHat, that's what I've been using.

  Obviously on this list there is mostly Xen users, and I feel like I must
be missing some great advantage so I am curious, those of you who prefer Xen,
why?

Re: [CentOS-virt] Hey

2014-01-28 Thread NightLightHosts Admin
I have used xen over kvm and others for a while.  It was what I just
started using first years ago.  With Xen I could manage domains and my
system seemed like a real server.  KVM just seemed like a command line
trick to me.  (I know it is not especially since its integration into
the kernel.)

xenserver is pretty sweet and there are some big products built around
it.  Citrix loves it too.  OpenStack is neat:
http://www.xenproject.org/presentations-and-videos/video/xpus13-rackspace.html

I was disappointed when redhat dropped xen :/  I mean now there is an
entire project around keeping xen on centos, etc.  This one.

In the end xen just seemed more strait forward.

I used to use Xen. As far as I can tell, I published the first SRPM's
for it, back when it was open entirely open source, before Citrix
bought it.  As far as I  can tell, the open source Xen suffers from
many of the same problems as KVM and qemu. Namely, the gui and command
line tool, libvirt, is poorly built overburdened debris that does
not fulfill *anyone's* standards of a good configuration tool,
especially the open source GUI guidelines written by Eric Raymond in
his Luxury of Ignorance essay.

That said, Xen suffers no more from it than KVM does. It also doesn't
have the stunningly painful requirements to override NetworkManager
and manually configure the bridge device, as documented by me years
ago at at 
https://wikis.uit.tufts.edu/confluence/display/TUSKpub/Configure+Pair+Bonding+and+Bridges+for+KVM+Hypervisor.


   Obviously on this list there is mostly Xen users, and I feel like I must
 be missing some great advantage so I am curious, those of you who prefer Xen,
 why?

Personally, I use Virtualbox or corporate supplied VMware these days.
Not becuase I don't like open source tools, but because I prefer to
spend my subtle confifation time more usefully than working through
libvirt and NetworkManager manual, poorly documented, unintegrated
confuiguration steps just to get things to work normally.

[CentOS-es] Instalar Gcompris

2014-01-28 Thread Ricardo
Tengo un cyber y cada año escogo una distro para usar en dicho local, este
año le toco a CentOS, he podido instalar algunas cosas pero me falta la
instalación de juegos para niños (Gcompris, Childsplay...) , espero q la
ultima opción sea compilar y si ese es el caso seria bueno aprovechar para
hacer el respectivo rpm de CentOS

CentOS es una distribución orientada a Servidores, si vas a usar en las PCs

That depends on your definition of broken. When it doesn't work out of 
the box it is broken even though it eventually underwent a miracle and 
began to do what I asked. I am still unable to install Centos 6.5 in 
vbox from the two DVD's. I still need to learn how to get 6.5 minimal 
connected to my LAN.

Presently it [6.4 Live installed in vm] is working as expected, doing 
the initial new system update which I do at this hour when usage is free 
from my ISP.

Again, thanks all for the fast responses,

a miracle implies magic.

[CentOS] NIS or not?

2014-01-28 Thread Sorin Srbu
Hi all,

We're getting to a point in our linux environment where it's starting to be 
cumbersome to keep shadow and passwd-files up-to-date for the users to login 
on each computer. Scripts can only get us so far. 8-/

I've looked a bit into central login systems for linux, and NIS and LDAP seem 
to be prevalent. NIS being the simpler-to-setup solution for small to medium 
networks as I understand it, while LDAP is the more modern and scalable 
solution.
See eg http://www.yolinux.com/TUTORIALS/NIS.html or 
http://sysadmin-notepad.blogspot.se/2013/06/nis-server-setup-on-rhelcentos.html.

NIS-wise, what is a small to medium network?
We have currently about 20-30'ish linux clients and servers, and the 
environment is not likely to increase much beyond this point.
Is a 30ish-computer setup, a small network?

The only thing I'm trying to accomplish is a system which will allow me to 
keep user accounts and passwords in one place, with one place only to 
administrate. NIS seems to be able to do that.

Comments and insights are much appreciated!

[CentOS] Recent version of Latex

2014-01-28 Thread Patrick Begou
I've moved most of my user's PCs from OpenSuse (11.x, unmaintainend now) to 
CentOS 6.4. On my old OpenSuse latex was texlive-latex-2010 and current 
version on CTAN is texlive-2013.

But on CentOS 6.4 I've only the old texlive-latex-2007 and several sty files 
available on my previous config are not available now and users cannot compile 
their previous documents.

Is there a Yum repo from where I can install a more uptodate latex environment 
for CentOS6.4 ?

Thanks

Patrick

Use IPA. It combines LDAP with Kerberos, a server-client environment is
easily setup and the documentation (RHEL deployment) is very helpful.

Thank you.
Can I use just the user authentication (uid/pwd) part and skip the whole 
mail-cocacho, or do these two go hand in hand when using LDAP?

Hi Sorin
of course: you may omit the mail cocacho and realize only the 
authentication cocacho in LDAP. For us, however, it has proven to be 
most advantageous to have both on LDAP.
You may also select to do first the authentication in LDAP and later on, 
if you are familiar with LDAP, realize the mail.

 Hi Sorin
 we use here LDAP  authentication and mail-control since more than 10 years.
 At that time, we did the conversion from passwd/shadow to LDAP using the
 tools on
 http://www.padl.com/download/
 which are still available, probably in a newer version...

 To represent a person or a service in LDAP we use the objectclasses:
objectClass: account
objectClass: posixAccount
objectClass: top
objectClass: shadowAccount
objectClass: mailRecipient

 To represent a mail user for postfix we use the objectlcasses:

objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: qmailUser

 To represent a Domain which we serve mail-wise we use the objectclasses:
 objectClass: qmailControl
 objectClass: top


 We also have developed an LDAP via Web Interface, which we use
 exclusively for LDAP administration.

 We have two LDAP servers, syncronized via syncrepl.

 Thank you.
 Can I use just the user authentication (uid/pwd) part and skip the whole
 mail-cocacho, or do these two go hand in hand when using LDAP?

 Use IPA. It combines LDAP with Kerberos, a server-client environment is
 easily setup and the documentation (RHEL deployment) is very helpful.

Thank you. I'll look it up.

LDAP and Kerberos though. That does sound a lot like Microsoft Active 
Directory. 8-)

 Hi Sorin
 of course: you may omit the mail cocacho and realize only the
 authentication cocacho in LDAP. For us, however, it has proven to be
 most advantageous to have both on LDAP.
 You may also select to do first the authentication in LDAP and later on,
 if you are familiar with LDAP, realize the mail.

Cool. Thanks!

I used NIS for many years while working on Sun Solaris and it worked 
extremely well, although when it breaks it can be a real challenge to 
figure out the problems.
I don't know how well it's implemented in Linux, bound to be a bit 
different than Solaris.  In either case if it's important be aware of 
the potential security issues related to NIS, mainly the clear text 
passing of the password which is what pretty much doomed it.

Depending on how ansi your users get I would recommend a slave server as 
well, you might also consider using autofs to mount the user's homes.

The biggest potential problem that you might run into when you first 
implement NIS is to take a look at the uid of all the users on each 
host, you will need to ensure that they are the same before you start 
NIS or else it will be a mess for the users because they won't own their 
own files.

With all of that said I do think though that LDAP would be a better 
solution although I've not used LDAP.

Good luck with it either way.

Re: [CentOS] NIS or not?

2014-01-28 Thread Kaplan, Andrew H.
We have been using NIS for over a decade on our network, and it has been an 
effective solution.
The network spans several subnets, and we have been able to deploy slave NIS 
servers on the various
subnets. The reason for this is several fold:

Quicker response for login and other domain requests
Network policy requires slave servers to be on subnets to reduce network 
traffic.

While the security is not as strong as it is for the LDAP solution, as long as 
you are employing
NIS on an internal network, you should be all set.

We use IPA on all servers and workstations.

I can't say how well it does compared to openldap but the replication is
quick reliable.


For example; we test IPA masters by (re)applying settings in user accounts

 The only thing I'm trying to accomplish is a system which will allow me

 Comments and insights are much appreciated!

 A related question: is NIS or LDAP (or something else entirely) better
 if the machines are not uniform in their login configuration?

At this late date, I'd be really, *REALLY* leery of using NIS. You say
that *most* of your traffic is local, suggesting that some of it is *not*.
And, for that matter, how good are the firewalls keeping other traffic
out?

I'd say no to NIS. Yes, other answers may be more difficult to set up, but
consider the alternatives.

 That is, we have an ever-growing list of special cases.  UserA can
 login to servers 1, 2 and 3.  UserB can log in to servers 3, 4, and 5.
  Nobody except UserC can login to server 6.  UserD can login to
 machines 2--6.  And so on and so forth.

Here you may not realize you're distinguishing between authentication and
authorization.

 I currently have a custom script with a substantial configuration file
 for checking that the actual machines are configured as per our
 intent.  It would be nice if there was a single tool where the
 configuration and management/auditing could be rolled into one.

We have an in-house written set of scripts that administer relevant
configuration files, including /etc/passwd. It copies the correct version
of that file (among many others) to each host, and shell of /bin/noLogin
works just fine.

 You’d be fine with IPA which allows you to create such rules.

I'd vaguely heard of IPA, so I just looked it up. *chuckle* You do notice
that it has its own implementation of LDAP and uses kerboros, right? So
seems like several folks are recommending LDAP and kerboros.

I sincerely hope it's easier to set up and administer and upgrade than
native LDAP. In '06, after a discussion with the other admin and manager I
was working with at that job, I volunteered to set up openLDAP. Let's just
say that the tools were NOT vaguely ready for prime time, though I did
find that running webmin helped a *lot* to get it working.

But that was nearly 8 years ago

[CentOS] Single sign-on for CentOS-6

2014-01-28 Thread James B. Byrne
Does anyone here use a Samba4 setup for single sign-on for MS_Win workstations
and CentOS-6 boxes?   Does anyone here use it for imap and/or smtp
authentication?   We are experimenting with replacing our existing Microsoft
domain controllers with Samba4 based controllers and are contemplating moving
all authentication for all our systems, Microsoft and CentOS based, over to
Samba when, or if, this replacement successfully completes.

Does anyone have any references for using CentOS with Samba domain controllers
that they can recommend?  I have found some but the few I have found tend to
be Samba3 specific.

You have to configure networking during the install and check a

it also applies to 3TB drive with 3TB partition, such as you typically 
use with LVM.

I don't like using raw disk devices in most cases as they aren't labeled 
so its impossible to figure out whats on them at some later date.

just use the gpt partitioning tools and you'll be fine.   as long as its 
not the boot device, the BIOS doesn't even need to know about GPT.

|parted /dev/sdb ||mklabel gpt|
|parted -a none /dev/sdb ||mkpart primary 512s -1s


that creates a single /dev/sdb1 partition using the whole drive starting 
at the 256kB boundary (which should be a nice round place on most raid,

 I believe xlrd does.:

 That's 0.9.2. I just installed the latest package from the usual repos,
 and it's  python-xlrd-0.6.1-10.el6.noarch, and my user reports that
 doesn't work. Suprises me, that being from Excel 2007, and Libre Office
 reads it fine. I gave that suggestion to him as a workaround - import into
 LibreOffice, and export, but he's trying to automate this. I did see what
 seems to be a perl package, but he's working in python.

I was able to install 0.9.2 with:

pip install xlrd

 IMHO this applies only to partitions (eg. 3TB HD with MBR 1x1TB, 1x2TB
 Partition).

 it also applies to 3TB drive with 3TB partition, such as you typically
 use with LVM.

 I don't like using raw disk devices in most cases as they aren't labeled
 so its impossible to figure out whats on them at some later date.

 just use the gpt partitioning tools and you'll be fine.   as long as its
 not the boot device, the BIOS doesn't even need to know about GPT.

 |parted /dev/sdb ||mklabel gpt|
 |parted -a none /dev/sdb ||mkpart primary 512s -1s

 that creates a single /dev/sdb1 partition using the whole drive starting
 at the 256kB boundary (which should be a nice round place on most raid,
 SSD, etc... the defaults are awful, the start sector is at an odd
 location)

Not a fan of that - a lot of the new drives actually use 4k blocks, *not*
512b, but serve it logically as 512. HOWEVER, you can see a real
performance hit. my usual routine is
parted -a optimal
mklabel gpt
mkpart pri ext4 0.0GB 3001.0GB
q
and that aligns them for optimal speed. The 0.0GB will start at 1M - the
old start at sector(?) 63 will result in non-optimal alignment, not
starting on a cylinder boundry, or something. Note also that parted is
user hostile, so you have to know the exact magical incantations, or you
get this is not aligned optimally, but no idea of what it thinks you
should do. What I did, above, works.

 Running Centos 6.4

6.5 is current, nobody cares for 6.4 anymore.

 Any Idea´s?

Put it into a Windows machine to switch it once. Then send it something 
like

AT^U2DIAG=0

over the serial line to switch it permanently.

I think Libre Office can be run from command line, headless, and it can 
be scripted.

Also look at unoconv from RepoForge. I am not sure about .xlsx, .but 
working with .xls is possible. Maybe automatic conversion older standard 
then unoconv?

I would have to ask why you're doing such a thing in the first place?  You have 
a perfectly good working Active Directory setup, that people are already 
familiar with, I suspect with existing MS clients which integrate fully (and 
properly) and you want to replace it with a Samba based setup.  Unless you 
have a relatively simple setup, I would say don't change.  However, if you are 
looking to move to something else, then do that.  Why fix to Samba?  Why not go 
with a full on Kerberos/LDAP environment?

FWIW, we use CentOS 6 with Active Directory Authorization.  Things have worked 
fine for us for about 1 year.  It took a VERY long time to get setup and 
working, but it is now.

 Does anyone here use a Samba4 setup for single sign-on for MS_Win

That is so cool!

Could you keep us updated on your progress on this?
Thanks.

FWIW, while I dabbled with Samba3 I never could get it to work properly with 
our AD. Turns out, the AD was set to a security model Samba3 couldn't handle.

Has this been resolved with Samba4?

Re: [CentOS] NIS or not?

Hi friend -

what is your end goal with this effort to obtain security with your 
nodes over the 'wire' -

there are some other solutions -- kerberos is now used heavily by 
microsoft so that's enough to make me
run for the hills... just saying..

i've set up other solutions to be sure -- even against the blasted (not 
a real LDAP) AD.

anyway.. just some thoughts... it's not trivial. any of the solutions, btw.
not at all..
