VMware is a company, not a specific product.

One (CentOS) may be supprted, the other (Ubuntu) not.

Can you expand on that?  Did they abandon VMWare Server altogether, or just
version 2?

I'm still using version 1.08, and it works fine, except that Win XP SP3
won't Hibernate or Stand-by due to an incompatibility with one of the VMWare
drivers.  I was using the VMWare save machine state, but it turns out that
shutdown and reboot is faster

Let us know  :-)

Nicolas: Three questions:

install with yum?

Question #2: What yum command can I use, to install everything in the
OpenOffice "Group", such as writer, calc, and many other packages?

Question #3:  What yum command should I use (the one below obviously
is not correct) to install the Applications/Office menus? (If I can do
that, I suspect this will work properly again)

I had removed (with yum) openoffice.org3.1-redhat-menus-noarch

night, when trying to install OpenOffice with yum and that's probably
why there's nothing in Applications/Office for the OpenOffice.org

[CentOS] Simple solution for small network in a school ?

2010-07-10 Thread Niki Kovacs
Hi,

I have to install a small network in a school in a nearby village. The 
network will be Linux-only, one server and fifteen desktops. Here's the 
idea.

1) Authentication should be managed centrally on the server.

2) User home directories should also be on the server.

3) Users should all have disk quotas, something like 1 GB per user.

4) Some shared directories should be read/write for a defined group of 
users (teachers) and read-only for others.

So far, I've only dealt with local authentication. I have a little 
practice in basic setups of Samba and NFS and managed to get these to 
work OK. On the other hand, I've never worked with NIS, LDAP or the likes.

My question is more general, and I don't want to go into technical 
details. According to the KISS principle, which solution would you 
recommend (or explicitly *not* recommend)? A mix of LDAP and Samba? Or 
NIS and NFS? And what's this thing called Directory Server, which 
vaguely sounds like it's the right way to go?

Any suggestions?

Cheers from the hot South of France,

Niki

We have a similar setup with OpenLDAP and NFS. Works OK, except all
directories defined are home to the users, and only their owner can
read them. Adding users or changing passwords is an admin-only hassle,
because we have never found a user management tool for LDAP which was
convincingly able to be given away to teachers.

Use some type of directory service (LDAP/NIS) coupled with an authentication 
service like Kerberos.

Basically keep passwords out of the directory and you need to have a Kerberos 
ticket to access the directory.

Not a problem, you can share these out via NFS and/or Samba.

Also not a problem to setup quotas and use rquotad to remotely query these from 
NFS clients. Samba has builtin support for quotas.

Standard posix perms can take care of that, for finer grained perms you can use 
ACLs.

NIS is easier then LDAP and might be a good quick-n-dirty way to get going 
initially. Just use a separate authentication service like Kerberos and keep 
passwords out of the directory service.

You can really mash all these technologies up.

If all clients are Linux then start with NFS/NIS/Kerberos then as things grow 
you can look to move to LDAP.

The "Directory Server" is a turn-key package for implementing LDAP plus 
Kerberos with a pre-established LDAP schema and tools to manage it.

Definitely worth taking a look at. Personally I don't have experience with it 
so can't recommend or not recommend it.

You COULD also have a Windows Active Directory server to provide LDAP and 
Kerberos services to your Linux environment. They definitely have nice 
management tools. MS for not-for-profit is dirt cheap. Run it as a 
VMware/VirtualBox/KVM/Xen VM. Hell, run the whole server as an ESXi host and 
have multiple VMs for redundancy/load spreading.

Standard UNIX uid/gid, served by LDAP, and handled by NFS.

LDAP is pretty straightforward.  There is a quite good article about
setting up LDAP (OpenLDAP) and migrating from file-based authentication
on the RedHat RHEL documentation site (this applys equally well to
CentOS).

LDAP and NFS.  Samba really only makes sense if you are serving
MS-Windows and/or Macs.  Samba would be combersome in a pure-Linux
environment.  NFS would propagate standard UNIX permissions
transparently.  You could also use automount to reduce 'clutter' (only
mount what is needfull on an as-needed basis). 

Visit:

http://www.deepsoft.com/2009/08/setting-up-thin-clients-at-the-wendell-free-library-part-1/

For an article on how I set things up at our local Library.  While this
article mostly covers a server serving a bunch of *diskless*
workstations, many of the basic ideas also apply to a situation with
workstations with local disks.

You might want to look at ClearOS before tackling this yourself.  It is 
CentOS-based but comes up with a slick web based administration program and 
uses 
LDAP for authentication out of the box.  It uses openldap and I think it is 
integrated with samba so you could use windows clients if you wanted.  On 
something of that scale I don't think you'd have to worry about the performance 
or replication differences in openldap or directory server - the administrative 
tools you use will be more important.

[CentOS] Redundant LAN routing possible?

2010-07-10 Thread Emmanuel Noobadmin
I've been reading that it's possible to set up a system with multiple
NIC to provide redundant internet connectivity such that it will
switch to a secondary connection if the primary ISP fails.

Is it possible in a similar way to setup redundant LAN routing? I read
that it is possible to aggregate/bond multiple NIC to stackable
switches that support link aggregation and redundancy. But if only
simple switches are available, is something like this possible?

e.g.
System A
eth0 -> lan switch/router 1
eth1 -> lan switch/router 2

System B
eth0 -> lan switch 1
eth1 -> lan switch 2

Then somehow specify that, if lan switch 1 fails, the two systems will
switch to using switch 2 so that in case of a switch failure, the
network continues to remain operational.

I'd think for this to be possible you will need a router with multiple
WAN addresses/interfaces... I am not sure how that pertains to your
LAN per se.

If you're clever with scripting and iproute2 commands, rules and multiple
routing tables, and everything's Linux, this is certainly doable. You could
have your System A ping System B's IP via eth0 every minute, and on failure
reassign its default route and IP to eth1. Meanwhile you can set up rules and
routes on System B so that whichever NIC traffic comes in on, the response
will use the same NIC ... stuff you'll find if you google around for how to
be dual-homed between ISPs is quite applicable here.

It's too complex to work it out for you in detail without spending an hour
on it. But I've done this sort of thing and had it work very well.

Many thanks to both Yves and Ned for the pointers. After installing
lm_sensors-2.10.8.-2 from elrepo, then installing the necessary drivers (also
from elrepo) for the sensors on my Shuttle SA76G2, the readings are now
available. For anyone else who runs into this, the SA76G2 needs the it87 and
k10temp kernel drivers.

Now I just have to get the ranges set correctly. Unfortunately, Shuttle
publishes absolutely nothing in the way of documentation, and their tech
support people refuse to provide information, claiming that it is proprietary.
I guess I'll post it in their user forums once I figure which measurements are
meaningful.

Thanks Again,

Yes. You can do it. I've done it before. All you need is the right 
choice of bonding mode . You set up bond0 for eth0 and eth1 and it 'just 
works'. To make it more robust, cross-connect the two switches as well.

Re: [CentOS] Redundant LAN routing possible?

2010-07-10 Thread Emmanuel Noobadmin
Thanks for the suggestion, I'll read up more about them. The
bond0 and just works sounds simple which is a Good Thing!  The problem
was the last time I tried to cross connect multiple switches,
everything just died so there must be something a bit more involved?
:D

In the mean time since my post, I came across STP (spanning tree
protocol) that seems to be designed to handle this sort of thing, i.e.
figure out the shortest path and prevent network shortcircuit like
what I had experienced with cross connecting multiple switches.

But it apparently takes 50 seconds to reconfigure anytime sometime in
the circuit fails. There is supposedly a Rapid STP that only takes 3
seconds. Several couple-of-years old search results indicate that it
was tested in 2.4 kernel and will be in 2.6 kernel. However, I cannot
seem to find anything newer that confirms if such functionality is
really in the current kernel. Anybody has any idea?

Since the elrepo kmod-k10temp/lm_sensors packages worked, then you may
also benefit from the elrepo kmod-powernow-k8 package.

With AMD Phenom II quad-cores running centos 5, kmod-powernow-k8
typically gives a 8-10C drop in core temperature at idle and a
significant reduction in power consumption at idle as described in this
centos bug report:

http://bugs.centos.org/view.php?id=3766

You will also likely notice that your cpu fan slows down at idle. It is
worth installing the kmod if just to quieten down the cpu fan.

As per the bug report, this issue should be fixed in rhel/centos 5.6
