Uno de los principales errores que mucha gente comete cuando implementa un controlador de dominio windows en linux es asumir que este deberia tener un funcionamiento diferente o incluso esoterico para hacer varias cosas. Nuestros amigos del proyecto samba mas bien se han esforzado para hacer q samba sea lo mas transparente para una red windows. Entonces para resolver determinados problemas debemos olvidarnos que es un controlador de dominio basado en linux y pensar solamente q es un controlador de dominio windows. para lo q tu estas buscando, podrias hacer uso de la funcionalidad del script de arranque en netlogon. Todo controlador de dominio (los linux tambien) tiene esa capacidad y desde ahi podrias mapear la unidad usando los comandos clasicos de DOS/Windows para ello. Si requieres q el mapeo sea personalizado, en vez de usar la funcionalidad global de script, a cada usuario le puedes asignar un script de arranque diferente con sus propias unidades. Si estas usando tdbsam es un poco mas complejo pq tienes q hacerlo a fuerza de comandos de samba para cambiar atributos, pero es factible tambien. -- Black Hand ___ CentOS-es mailing list CentOS-es@centos.org http://lists.centos.org/mailman/listinfo/centos-es

Hi there, I am slightly confused by the RHEL release notes and an earlier thread here about rsyslogd, so I hope someone can clear this up for me; I see that rsyslog is included in RHEL as of 5.2 (and so will be available in CentOS when 5.2 is ready) however there is no indication of whether it has been made the default syslogger or not - is it an optional package or installed by default on a fresh install?

[CentOS] Could this be an advantage of CentOS over the PNAELV distribution?
Hello all, I understand that when releasing updates the CentOS team strips logos and such things from the upstream sources. If I'm not mistaken there is also a certain QA process going on before the actual releases, at least for major updates like the upcoming 5.2 version. Does this happen also for security updates? Since I don't mind the small delay from the upstream releases I was wondering if the additional QA process could actually be an advantage over the PNAELV distribution. This could be even more true if the QA isn't only related to CentOS specific changes but it's done even for practically untouched updates. Is this assumption correct?

Re: [Fwd: Re: [CentOS] School Server Setup]
Given the cost and ease of setup, CentOS is a great choice, using one of the machines as a server and the other as clients. CentOS is very robust, and can be configured for one machine to hundreds, so to ear mark it as only a Enterprise package is wrong, and no there isn't a great deal of setup involved. With the tools that come with the package a working server can easily be configured and running in a afternoon, so the task isn't all that tough. Plus you have the wealth of the CentOS community to help if you get in trouble. That's my nickels worth, you can keep the extra three cents... john plemons Ralph Angenendt wrote: Alain Terriault wrote: For 25 systems and if you want this done without spending to much time, Clarkconnect would by my first choice for server side OS (#2 would be SME).

Re: [CentOS] Apache jserv monitoring?
Sounds similar to the mod_jk connector in apache to connect to tomcat. When I had to deal with this I setup a dedicated apache instance on each system running tomcat whose sole purpose for existence was for testing that connector. So say setup an apache instance on another port, and have it direct all traffic back to mod_jserv, then hit the apache instance with http. It's not perfect but at least for me apache was a lot more stable than tomcat especially in such a basic configuration, so it worked well as a way to test the health of the mod_jk connector. Excellent idea, Nate. I already have apache installed on all these servers, so it should be fairly trivial to set up a local test site just for this purpose. I'm going to test this out in our lab environment today and see how it performs. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Apache jserv monitoring?
Sean Carolan wrote: Sounds similar to the mod_jk connector in apache to connect to tomcat. When I had to deal with this I setup a dedicated apache instance on each system running tomcat whose sole purpose for existence was for testing that connector. So say setup an apache instance on another port, and have it direct all traffic back to mod_jserv, then hit the apache instance with http. It's not perfect but at least for me apache was a lot more stable than tomcat especially in such a basic configuration, so it worked well as a way to test the health of the mod_jk connector. Excellent idea, Nate. I already have apache installed on all these servers, so it should be fairly trivial to set up a local test site just for this purpose. I'm going to test this out in our lab environment today and see how it performs. If this is old enough to be running a Sun 1.4.x JVM and the web server generates images, there was a bug that caused the JVM itself to leak memory under certain circumstances.

They make nice, small, safe effective Gateway or server. They are not a sysadmin (shell) playing ground, 95% of the work is done from the web interface, a little bit like webmin.

If you dd the first sector of the drive though you will duplicate the partition table and grub boot loader to the other drive. Then md-device-mapper will take care of copying the data over.

RE: [Fwd: Re: [CentOS] School Server Setup]
I realise linux distros are rather a religious matter where each individual/user/sysadmin/whatever think that their particular distro is the best. 8-) With that said, in my case, chosing CentOS was actually a no-brainer, as our department had already settled with RHEL3/4 for application reasons years ago. Furthermore, since CentOS is a binary compatible with RHEL, and looks and feel the same (minus the RHEL-logos), it's also easy to test things out with a free OS first. I however really started out with Fedora Core for a short while, but was flustered with the fast update-schedule. Anyway, I don't even know or remember how I found out about CentOS, only that I felt this strange rush, much like when you put a nice well-worn-in suit or something and it doesn't chafe anywhere. I never bothered looking for another distro after finding CentOS. I even installed it for the beloved mother after I found a potential rootkit on her WinXP Home Ed-machine. I had had it at that point... After installing CentOS5 for her, I applied the Redmond theme and let her play around for a bit with it. Worked like a charm. The hd died on her machine a few months back so I reinstalled it for her again, this time w/o the Redmond theme, and it still works like a charm for her. From a user-perspective, if a 50ish-year-old woman with no interest in OS:es (or anything IT for that matter) can use CentOS without a hitch, then neither should anybody else. It just works, which I rather like, to put it mildly... If there ever was a linux-success story, this is the one. [advocate mode]If you like CentOS, please buy a RHEL entitlement whenever possible.

From this we can observe that when the disks are identified as auto-raid and their superblocks are read it tells them what RAID they belong to and their order in the array. What happens if a duplicate descriptor is encountered? And how does it determine which disk is the official disk? I have yet to find those answers, but let me hypothesis that it ejects either a) the disk with the oldest timestamp, or b) the disk with the odd checksum out of the array.

[CentOS] LDAP syncrepl incompatibility between CentOS 4.x and 5.x
All, After many hours of research I have found there is a incompatibility between OpenLDAP V2.3.x and V2.2.x, or atleast between V2.3.27 the current version on CentOS V5 and V2.2.13 the current version on CentOS V4. The syncrepl feature of OpenLDAP, to keep multiple slapd servers sync'd, was working between CentOS 4 and 5 at one time, as that is how I populated the slave servers. I've found references indicating protocol changes and incompatibilities between these versions and indeed looking at detailed debugging logs I can see the protocol falling apart between the two versions.

Re: [CentOS] Centos 5.2 and Xen
If you only have 512mb of ram, there's almost no reason to virtualize. Windows needs a minimum of 128-512MB to run stable. I highly suggest that you get more RAM - its very cheap these days. If you want to dedicate a box to virtualization, and won't be using more then 4GB of ram for your virtual machines - I highly recommend xenserver express. Its free, but has much better performance then vmware. Looking at it more closely, it seems to be rhel5, or more likely centos5 under the hood, so you can probably use the host for other things too. I wonder if it can be combined with other techologies - KVM, openVZ, etc to give more then 4GB of ram for virtualization? I tried installing vmware, but it wouldn't run under.a xen kernel.

There is an RPM package available on VMware's site: $ rpm -q VMware-server VMware-server-1.0.6-91891.i386 It's only available in i386 package but installs fine on x86_64 and supports 64-bit VMs provided the underlying hardware supports it. I believe VMs are limited to a max of 2 processors each. I've used VMware Server on systems varying from old AthlonXP, 512MB RAM through to Intel Quad Core Q6600 with 4GB RAM. Note VMware will run on older processors without hardware virtualization. In my experience there's little noticeable difference between software and hardware virtualization (on VMware), and each run at about the perceived speed you would expect if it was on native hardware (I've not conducted any benchmark tests). The main consideration is that you have enough RAM to support the host OS (CentOS) and any VM(s) running on it. I've not used Xen so can't offer a comparison. Ned: I was very interested to read that you've run VMWare Server on systems with only 512 MB of RAM. I haven't tried it, because the box I can use only has 512 MB of RAM. My impression is that Xen is much more demanding about HW.

[CentOS] Bind acl statement issue
From the manual, localnets matches hosts belonging to a network for which the server has an interface in. I have a dns server in a dmz with an ip of 192.168.2.2 in /24. Named.conf has 3 views, localhost_resolver - localhost, internal - localnets, and external - !localnets; !localhost. I have a management workstation in 192.168.0.0/24 that is connecting and receiving the following debug: client 192.168.0.44#2188: no matching view in class 'IN' I don't get it?

The 4GB limit is artificial, and only applies to the vm's started using their closed source XenSource. The host OS is most likely CentOS 5, and sees the whole 8GB (although it's not x64, so I'm guessing they use PAE or something.) I only need 8GB of ram support, and no other features that are offered in XenStandard, so it seems kind of a waste to pay $1k per server for that. If another virtualization technology was installed on that OS, you can get the use of the other 4GB, and if not, I can always run my apps on Dom0, although I'd prefer to not install too much stuff on Dom0.

Yea, I've been playing around with this. The performance seems on par with the XenSource drivers, but like you said, it's pretty beta. James has been great in fixing the bugs, but it's just not ready for production use right now. Without using the GPLPV drivers, Xen is not ready for production use, the IO throughput sucks, and there is no graceful shutdown. If XenServer Express would only allow for 8GB, it would be perfect. The administrative interface is really polished and fully featured (except things like migrations, which understandably come with the enterprise version). Once the GPLPV drivers mature a little bin and someone makes some decent admin tools for Xen, Xen will be ready for the enterprise. I bet a company can make good money just developing and selling the admin tools for Xen. Russ ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Problems installing 5.1 on a Tyan Thunder HEsl with a SCSI controller
Hi, I'm trying to install 5.1 using the onboard LSI Symbios 53C1010, and I'm running into some trouble. When the computer first boots, the SCSI BIOS sees the three HDDs, but when I go to install, the installer hangs for a while at inserting the sym53c8xx driver and if I go over to the screen on F4 it shows that it is trying to scan the SCSI bus and is resetting all of the IDs. Once that is done, it moves on the the actual installer, but does not see any drives. I'm kind of at a loss at the moment. I feel like there would be a kernel boot option that I could give the installer, but I don't know what that would be. I know the SCSI IDs of the three HDDs (and the controller), is there a way to say just use these IDs and move along? I'm currently downloading a Fedora 9 CD (I don't have a spare DVDROM) to see if a newer kernel will help, as going back down to CentOS 5.0 didn't (I had it at hand). Thanks for any help! --Tim ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
