There is no Edit link in the RecentChanges page, as that gets
autogenerated somewhere.
I thought that some time ago too ... and almost turn crazy looking the
place where that table was generated but it really is included inside
the wikicode of RecentChanges page.

acl_rights_before = u${WIKISUPERUSER}:read,write,delete,revert,admin \

In a configuration like the above where $WIKISUPERUSER is
AlainRegueraDelgado the RecentChanges edit link appeared to me, so
that was how I could change the style of that table.
That's a cosmetic change not a big thing at all.
Also we have the update modern-CentOS-1.10.1 available on the wiki
page. The print.css was fixed.
Going to take a look at that later.
You know, I noted the print.css error thanks to your previous output

Hola Jesús: 2008/5/22 Ms.C. Jesús Graverán Mesa [EMAIL PROTECTED]: Estimados colegas, alguien podría enviar a mi e-mail documentación de la arquitectura, tanto desde el punto de vista de hard, como de soft, de un nodo (Area de Servidores) para prestar servicios de todo tipo y realizar su control y supervisión. La administración de un nodo es algo demasiado complicado como para recibir una respuesta sencilla. Muchos de los suscritos a esta lista han dedicado décadas (inclusive) a trabajar en este campo y aún estoy seguro, admitirian que todos los dias tienen que estudiar algo nuevo que aparecio. Primero servicios. Que servicios ofreces tu nodo. Dices Area de Servidores. Hay demasiados servicios que se pueden ofrecer. Servicios de todo tipo es una definicion que no sirve. Recuerda que la gente que trabaja con computadoras tienen a pensar en binario (y no puedo evitar el cliche: hay 10 tipos de personas en este mundo, los que entienden binario y los que no). Algo que te va a ayudar es el modelo OSI. Aplicalo a los servicios. El nodo da servicios en que capa? Las aplicaciones, protocolos van a variar para cada caso. Enrutamiento y DNS van mas abajo que si hablaramos de mensajeria y web. Un servidor de ficheros lo pondria mas arriba (ya con autentificacion de usuarios casi seguro). Ya tienes definidos los servicios (si el nodo ya existe, estoy seguro estan definidos pero como no los mencionas empece desde cero). Ahora vas para el hard y el soft. La capacidad de procesamiento, la posibilidad de adquirir licencias y/o soporte tecnico, el presupuesto de la empresa. No hay soluciones finales, solo de compromiso. Lo que para uno es excelente para otro es imposible. Es una lista de CentOS, utilizo CentOS, sin embargo, me he visto en la situación de recomendar un servidor con MS Exchange como la mejor variante posible. Trata de tener siempre el mejor hardware posible, lo barato sale caro en un cuarto de servidores (bpa cierto?). En cuanto a sistema operativo, la elección esta claro que sería siempre CentOS. A nivel de empresa es una de las mejores opciones. Digo empresa porque instalar un sistema operativo en un servidor significa no tener que reiniciarlo en años (ja! siento la envidia de los sysadmin Windows). Mira Ubuntu, actualizan cada 6 meses, claro, nadie actualiza un servidor cada 6 meses, ni un año, por eso liberaron la version LTS (long term support) que te garantiza 5 años de actualizaciones para una misma version. No estaria mal, solo que ... Centos ya lo hace hoy en dia por 7 años, Ubuntu esta por probar ese soporte, CentOS ya lo ha demostrado en la práctica (bueno, gracias Red Hat!). Si no encuentras diferencias entre 5 y 7 años, si, creeme, las hay. Va quedando la parte de supervisión y control. Existen excelentes herramientas para lograr esto pero una vez mas, depende de los servicios que hayas implementado. Nagios, MRTG, Munin, Cacti, Zenoss (o algo asi), el listado es realmente grande. En UNIX existe una filosofia que es de tener programas pequeños, que hagan solo una cosa pero que la hagan bien. Luego, puedes ir concatenando esos programas para realizar una tarea compleja. Te sugiero que apliques esa filosofia a la tarea a la que te estas enfrentando. Si trabajas en el BPA (como indica tu email - Banco Popular de Ahorro) me consta de que tenian un excelente nodo en la Habana. Incluso solían tener un irc nacional. El nodo de tu provincia de provincia deberá tener implementado ya un gran número de servicios. Deberá existir una arquitectura ya establecida (hard/soft). Tienen un jabber nacional por lo que veo en tu pie de firma. Empieza por ahi, mira que es lo que ya existe, intenta entender lo que hay y responderte tu mismo las preguntas de porque se hizo asi. Si encuentras algo que no te convence, pregunta en la lista. Quizas encuentres algo que pueda mejorar tu nodo. Entender como funciona tu nodo provincial te va a llevar a conocer y relacionarte con gente del nodo central. Una vez que te conozcas tu nodo provincial como la palma de tu mano (y ya conozcas a los del nodo central) empieza a averiguar como funciona el nodo central. Todas las dudas que tengas las puedes preguntar en esta lista. Pero te va a ayudar mucho a obtener respuestas si haces preguntas concretas.

Re: [CentOS] COBOL
Michael wrote: Just curious, maybe some old timers could help me out. I am working with a company that is migrating 20 years of Mainframe Software Development to Unix, HPUX. How much harder would it be to go to Linux, Centos Linux? I think you would be better served looking for a flavour of COBOL that provides portability via platform independence, rather than choosing your platform and then a COBOL to suit. We use ACUCOBOL from Acucorp for this reason. Our code, once compiled, will run on many different platforms without us doing anything. Acucorp had the write once run everywhere idea well before Java did. Also, anyone have any experience with Fujitsu Cobol on Centos? The Fujitsu people only support Red Hat, and said I'd be on my own with Centos. In other words if it works, then I don't care about Fujitsu support. I know some of you are thinking, did someone say COBOL? Nobody uses COBOL anymore! If so, let me say You are wrong. Many large corporations are taking their old business logic that was written in COBOL decades ago, and moving it to new modern platforms, like Linux. Programatically giving these applications a GUI face-lift, while maintaining their original business logic. I know because many companies pay me to do just that. I have a client that wants to use Centos Linux with Fujistu Cobol, and Fujitsu says it's gotta be Red Hat, any help will much appreciated. I know COBOL is still out there, and the latest tools for GUI development let you build apps that users can't recognise as COBOL apps. Business logic in COBOL is rock solid and won't be replaced anytime soon. With a GUI front-end, why change?

[CentOS] question on minimal install using CF as /dev/sda
Hi all, We're attempting to use CentOS 5.1 on a test platform which uses a CF card as it's primary storage. (MB: ETX-LX) The BIOS supports booting from CD and/or the CF. Issues we've run into are: During installation of CentOS 5.1, it appears all goes well through partitioning, package selection, interface configuration.

On Thu, May 22, 2008 at 3:42 PM, Dean Maluski [EMAIL PROTECTED] wrote: Unclear on how to recover from failed boot drive? SDA has failed but I'm still able to boot. I need to replace primary boot drive. Upon initial build I created a RAID 1 mirror of /boot dir/partition. How do I get system to boot off second or third drive so that I can replace /sda? If you have mirrored /boot, when grub kicks in, go into edit mode and replace root (hd0,0) with (hd1,0) or so on. If you want to do this automatically, you should have had fallback parameter in the menu.lst and two or more copies of the kernel entries but the change above will let you boot from one of the other drives. Right now I am converting a system that was incorrectly set up to software RAID1. Hope it works, the server is in the wrong continent. :-) If only the sysadmin installed it with RAID1 to start with. So the grub should look like: default=0 fallback=1 and then two blocks of the same kernel configuration, one with root (hd0,0) and one with root (hd1,0). The rest should be logical volumes or /dev/md references so the kernel will pick up the right one, hopefully. -- Hakan (m1fcj) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Failed boot drive
Unclear on how to recover from failed boot drive? SDA has failed but I'm still able to boot. I need to replace primary boot drive. Upon initial build I created a RAID 1 mirror of /boot dir/partition. How do I get system to boot off second or third drive so that I can replace /sda? I've successfully replaced /sdb sdc raid 5 drives in the past but have always struggled to get primary boot drive replaced. Read HOWTO's in the past but it's been an unsuccessful pain and eventually just did a full rebuild. I just read another HOWTO and as confused as I was several months ago, nothing on getting system to boot from alternate drive. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Strange NTP problem
I'm still having this issue. Here is another update. I noticed that the drift file for the system with the problem contained 0.000. On most other systems this contains a positive number (and on two a negative number). I deleted the drift file, resynch'ed the time with ntpdate hostname, restarted the NTP daemon, and waited for the drift file to be recreated. It again contained 0.000 and the output of ntpq -np looked like this: remote refid st t when poll reach delay offset jitter == 10.101.32.104 67.128.71.65 3 u 49 64 3770.611 1871.40 987.132 *127.127.1.0 .LOCL. 10 l 48 64 3770.000 0.000 0.001 I replaced the drift file with the contents of the file before the upgrade to CentOS, resynch'ed the time, and restarted the NTP daemon. But after a little while, the system is bound to itself again. BTW, the output of the cron job running ntpdate once an hour showed that the system has a very steady drift of 14.9 seconds every hour. Does that seem excessive? NTP should be able to handle this, right? Alfred ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] IPTables help
I have a dual homed server in an install for someone who is very cost sensitive. This server originally is being setup as an Asterisk server, but now the simplest thing for me to do is also set it up to provide internet access for the small shop as well. So it will have one external, WAN facing nic that needs all incoming ports except UDP 5060 and 1 - 6 blocked for all but two ips. The internal, LAN facing NIC will need all ports except voip/dns/http blocked to it, and need to provide masquerading. I have limited experience with iptables and would love some guidelines. Any pointers would be greatly appreciated! Thanks, jlc ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Strange NTP problem
I had a similar problem on a different server that I fixed last night. Evidently it had a BIOS level feature that tried to modify the CPU clock rate, much like cpu-freq does within the kernel, and was doing so by messing with the system clock impacting the RTC. I was drifting all over the place until I found and disabled that feature (foxcon board, something like foxstep I believe is what it is called in BIOS). Not sure if your lenovo boards have that feature, but i know that some ASUS boards do.

On one of those systems the clock is running slow (5+ minutes from yesterday to this morning and another minute since this morning) despite the fact that NTP is running on all of them and they all have the exact same /etc/ntp.conf file (I compared the MD5 sums of that file on all the systems). Here is the output of grep ntp /var/log messages on the system with the problem since I restarted the NTP daemon earlier today: A slew of 5 min/24 hrs should be in the range of fixable. May 20 11:35:38 hepdsw03 ntpd[31792]: frequency initialized 0.000 PPM from /var/lib/ntp/drift This is very suspect. Are there any SELinux or other log messages suggesting that ntpd isn't able to write to its drift file? Your local clock is definitely drifting, so a 0.000 value is bogus. It may indicate that there's a disconnect between ntpd and the filesystem. I'd be interested in the output of ntpdc -c kerninfo; on most systems the 'pll frequency' value is a close match to the figure in the drift file.

Sync-ing to local before your network time server means that your machine doesn't want to believe your server -- and you should see a kernel time sync enabled message once the machine has sync-ed with the time server. You said the machines are identical. Could there be any variation in the BIOS revision level or its settings? Sometimes ACPI stuff can mess up ntp. Also -- the log messages you provide have no step time server reference.

In fact, my experiences with RedHat Support, which were not in the least bit negative, led me to abandon RedHat, first to WhiteBox and thence to CentOS. The practical matter is that RedHat Support is provided in layers, with minimally experienced person filtering support calls. This was, and I expect still is, the case regardless of what level of support is purchased. By the time a serious problem got to a person in RedHat who possessed anywhere near my own experience with the systems under consideration either I had already solved the issue (usually with help from Goole or project specific mailing lists), identified a satisfactory workaround, or had determined that the problem was unsolvable in the timeframe required with the resources available. RedHat support people were unfailingly polite and helpful, but the fact remains that the value for fee was not evident. Immediate support (which is really the only kind that matters to an organization, anything else is really a development project of some sort) for open source systems comes in two basic flavors, enlightenment and custom consulations. Enlightenment is provided by informed individuals who are willing to share their knowledge and experience with others who problems are products of their own ignorance. Members of this mailing list have provided enlightenment to me on many, many occasions. Custom work is either provided from ones own resources or is contracted out to people who really know the system you need fixed/enhanced within a minimal amount of time. I have engaged open source software authors to enhance their products with features that our firm desired on many occasions and in fact am doing so with one at the present time.

RH is a packager, which is not to denigrate either the value of the integration work that they do, or its technical merit.

I agree support contracts from Redhat or Microsoft or Novell provide very little value on the surface, but there are advantages to these contracts besides phone support. 1) Third party vendor support. These contracts and installations will allow your software, hardware and development vendors to provide you with the support you need/want. 2) Service agreements. Just like there is an EULA there is also a vendor agreement within the contracts. Read them carefully. In there there are terms that the vendor agrees to meet that are beneficial to the long term support of their product. 3) Indemnification. Not all vendors provide this, but most do. This will assure you, management and legal that your company will not be held legally accountable for any intellectual property or copyright violations that may occur due to improper licensing on behalf of the software vendor. 4) Compliance. Most regulatory controls require that there be some level of service contract on the software that constitutes your primary production environment.

You're talking about mirrors over stripes, but I'm talking about doing it the other way around. Your way has the advantage of letting you add disks in pairs, but to get that you get only single-disk redundancy: if a second disk goes out, your array is gone, no matter which disk it is. If you do it the other way, you have to use groups of 4 (two mirrors striped together) but you get the advantage that with a single disk missing, you can lose another if it's in the other mirror. Of course, if you lose two in the same mirror, you're toast. And what would you recommend on 8 / 10 HDD's? As I said, usually RAID-5 or -6 usually makes more sense with so many spindles.

Thanks.
mhr
Dealings with SELinux issues typically do not lend themselves to short
answers. SELinux is like an onion, each each exception blocks access until
resolved. Thus each policy change has to be made individually and then the
process retested so that the next impediment evidences itself.
On CentOS-5 your friends are:
# grep avc /var/log/messages
# grep process /var/log/audit/audit.log
and some of the more useful utilities are:
# audit2allow
# audit2why
# chcon
# restorecon
# sealert
# semanage
When I suspect (and that is often the hardest part of the whole exercise,
realizing that SELinux is the problem) that SELinux is involved in a problem I
start by checking the system log file /var/log/messages with grep avc. If I
see things like this:
# grep avc /var/log/messages
May 16 04:02:33 inet01 kernel: audit(1210924952.785:22973): avc: denied {
read } for pid=22282 comm=prelink name=setserial dev=dm-0 ino=3309644
scontext=user_u:system_r:prelink_t:s0
tcontext=system_u:object_r:rsync_data_t:s0 tclass=file
Then I infer that I have a problem with either the SELinux file contexts or
the system policy file. If the SELinux problem is announced at the desktop
then you may also find it useful to check for this:
# grep setroubleshoot /var/log/messages
In which case you may see something like this:
Dec 17 14:13:24 inet01 setroubleshoot:
SELinux is preventing /usr/sbin/httpd (httpd_t) write to virtual.d
(etc_t).
For complete SELinux messages. run sealert -l

the directory and very few processes (SELinux Domains) are allowed to write
... yada-yada-yada...
...
Allowing Access
You can attempt to fix file context by executing restorecon -v virtual.d
The following command will allow this access:
restorecon virtual.d
And then you can try that, although I have rarely had a problem with SELinux
solved so simply:
# cd /path/to/virtual.d
# restorecon virtual.d
Anyway, if that does not work, or one never received an setroubleshoot report
to begin with, then I end up turning to audit2allow. I do something like this
(where rsync is the process that I am having difficulty with, it could be
httpd, vsftp or anything else):
# grep rsync /var/log/audit/audit.log | audit2allow
Which may yield a report something like this:
#= prelink_t ==
allow prelink_t rsync_data_t:file read;
Now, if this does not look too alarming in terms of the access that rsync
seems to be seeking (being able to read files to be transferred seems a
logical enough expectation and the benefit/limitations of prelink seem to
require access in this instance) then we can add this permission to our policy
via a local module. You make one of these in this fashion:
#
# grep rsync /var/log/audit/audit.log | audit2allow -M localrsyncmod
IMPORTANT ***
To make this policy package active, execute:
semodule -i localrsyncmod.pp
#
Again, you simply follow the instructions given in the report.
# semodule -i localrsyncmod.pp
Now you do yet another test and check the log files. If the problem is fixed,
then great, you are finished. Usually, however, SELinux issues continually
reveal one permission problem after another, sometimes with different
processes, until, at last, they have all been accommodated. Consequently you
end up re-running your tests, checking the audit files, and modifying the
local policy one item at a time.
Note that simply overriding what SELinux is prohibiting is not what I am
advocating here. Sometimes the problem is that the software needs its file
system access expectations trimmed back and that requires filing a bug report
with the maintainers. However, in a production environment you normally just
have to get things working and what I usually do is weigh what the program is
requesting against what I want it to do for me. Often the problem is that the
default policy is simply too restrictive. On rare occasions I do actually
file a bug report but almost always override the local policy anyway just to
get on with the
[CentOS] Current Chipset Compatibility
Can someone make a recommedation as far as best chipset for Centos 5.0 or 5..1 using a Q6600 series CPU with chipsets that have onboard VGA? From poking around it looks like the G33 and P35 are not supported or have problems until the newer 2.6.22 kernel (the iso's appear to be earlier than that, think it was .18)?

it's attempting to reattach to a session that doesn't exist and then
it fails. I could be incorrect, but at this point it's simply a data

On the client machine (assuming it is linux), have you removed all

Don't remove the config directory or else you'll have to set up the

On Thu, May 22, 2008 at 12:01 PM, Warren Young [EMAIL PROTECTED] wrote: At any rate, RAID-10 shouldn't be *slower*. I've actually seen equipments where RAID-10 was slower for reading than RAID-5 with the same number of disks. RAID-10 depends on the ability of the controller of balancing reads between the two disks (because as both have the same information, it can choose from which to read). Most implementations in cheap controllers (cheap as opposed to hundreds of thousands of dollars SAN controllers) do not implement this in the smartest possible way. With RAID-5 there is not such a choice, the information must be read from the disk that holds it, which means all implementations must do the right thing, which will end up striping reads across all (but one) disks. In any case, I've used RAID-5 with databases and it works pretty well. The biggest problem with RAID-5 (especially on big volumes) would be the time to reconstruct if a disk fails. But if you're using good quality SCSI drives that tend to last long, I would consider using RAID-5. As with any other performance-related issue, the answer, as usual, comes from the benchmarks you do with your own application. Anything else would be just theoretical and could not even apply to your particular case. HTH, Filipe ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Your way has the advantage of letting you add disks in pairs, but to get that you get only single-disk redundancy: if a second disk goes out, your array is gone, no matter which disk it is.

This CentOS wiki may help: http://wiki.centos.org/HowTos/Network/IPTables Akemi Akemi, That was helpful (I should have checked the wiki:). After reading that and the RH related links, I think I have what I need but I am unclear about one aspect. What is the correlation between filtering LAN based connections destined to be masqueraded out and what can even get to the internal NIC? I see the chains are obviously distinct from each other, and I assume the tables are as well. So to control what may ingress an interface destined for the server itself, you write a rule for the default table's INPUT chain, to control what may be masqueraded/DNAT'ed, you write a rule for the either the NAT tables PREROUTING chain or the default table's FORWARD chain, or both? In looking at examples for setting up NAT, I don't see people typically lockdown what may masqueraded, so I am not seeing how to do this. Buy my inclusion of at least one rule, am I properly prohibiting anything else? Is there any significance to the order in which I setup masquerading and then lockdown what hits the FORWARD chain?
