Yo soy una de las personas a las que menos le gusta las normas por normas nomás... de manera que lo que voy a decir debe ser tomado como una sugerencia, nada más. No doy consejos ni normas. La idea de las mayúsculas viene de hace muchos años, y fue implementada (entre todos los participantes de IRC original) para darle sentimiento al texto frío del chat. De esta manera, se llegó a un acuerdo de que escribir en mayúsculas era el sinónimo de gritar en el lenguaje hablado. Por eso se tomó como netiquette o norma de etiqueta de red que a no ser de que quieras gritar, no se usen texto completos en mayúsculas. Esto es independiente de si tiene contenido o no, de si está mal escrito o no, o lo que sea... Es simplemente un común acuerdo entre todos los que pertenecemos a ésta y otras listas y foros De la misma manera que no nos gusta de que nos griten en el lenguaje hablado, aquí tampoco nos gusta. Por eso fue el comentario del amigo. Además puede ser más dificil de leer por algunos... y tal vez no por otros. Además acá hay un comentario, http://artigoo.com/escribir-en-mayusculas-no-es-gritar que no comparto en absoluto, como tampoco escribir todo en minúsculas y con faltas, a pesar de ser yo bastante bruto con la ortografía. :( La reglas de escritura dicen que se deben usar tanto las mayúsculas como las minúsculas, signos de puntuación, etc. Y creo que eso es lo que debemos (o deberíamos) hacer... si si. Simplemente era una aclaración de una costumbre aceptados por todos, que puede (o no...) valer como regla simplemente por la condición de usos y costumbres, como se dice en la jerga legal. Alguien dijo (con razón) de que al aceptar estar en esta lista, debemos aceptar las reglas internas; y esa es una de ellas. Espero haber aportado algo a la pacificación y no lo contrario.

Osea, si solamente la producción debe ver ese sitio, pues restringe a nivel de firewall el acceso a las IP de confianza 2.- Revisa los logs de conexión, para que veas que solamente los usuarios que deberían acceder a dicho sitio estén entrando 3.- Mantente monitorizando en búsqueda de inyecciones SQL (si trabajas con algún motor de bases de datos) entre otras gamas de xploits 4.- Limita el número de conexiones a las que debiesen poder ingresar De todas maneras cualquier protección siempre es poca, no existe el sistema 100% seguro, solamente existe el nivel aceptable de seguridad, ten siempre presente esto.

En cuanto al tema que están tratando, yo una vez hice una copia tal cual de un server utilizando vmware de la siguiente forma: -El server viejo lo traspasé a una Maquina Virtual -La maquina virtual la traspasé al server nuevo Todo funcionó perfecto considerando que el hardware cambió.

[CentOS] System hanged - no info in logs.
Hi All. I had today a problem with my mail server (2.6.18-274.12.1.el5 #1 SMP Tue Nov 29 13:37:35 EST 2011 i686 i686 i386 GNU/Linux, CentOS release 5.7 (Final)). On my Cacti graphs I see that there has been much I/O write on the disks and then there is no more info. Also in logs (messages, dmesg, netconsole) there is no info for about 15 minutes when there was a problem with the server. I would like to have some info in such situations. Do you know any solutions? Best regards, Rafal. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] FSCK on mounted filesystem (LVM/DRBD)?
Hi All. I have two running servers (drbd primary, drbd secondary). When there is a problem with one of them we switch to the second one. Currently on the /dev/drbd0 (it has /xxx ext3 filesystem directly on it) we have some filesystem problems (after fsck -n). I would like to correct these errors but the filesystem should be unmounted first (I would like to avoid it if possible). Is there a way to make fsck -a on mounted filesystem for ext3? My setup is: ext3 filesystem (problems) ^ DRBD ^ LVS ^ RAID Any ideas? Best regards, Rafal. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] rhel/centos alternative to logwatch?
Am 08.04.2012 03:37, schrieb Joseph L. Casale: I just assumed there was something newer out there. 2007 was the last release notes for the version installed on centos. There is a newer version out there, but that would be off of the base repo and not sure if I want to go that route in the how-to. Dates aren't always a good judge of package quality. In the case of of this one, there really hasn't been a need to update it, as it just works. I assume some scripts have undergone changes though... The scripts are exactly the point. The most frequent reason for a lot of unmatched entries showing up is that the corresponding logwatch script is out of date wrt the program whose log is being watched. Program maintainers tend to change the wording of messages on a whim, and the logwatch scripts need to be updated to keep up with them. So yes, there is a constant need to update logwatch, specifically its scripts. -- Tilman Schmidt Phoenix Software GmbH Bonn, Germany ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] strange partitioning problem
Hello listmates, Here's I am, trying to install Centos 6.2 64-bit on a server with 24 TB of disk RAIDed as RAID 6. So I get this 18 TB disk (the RAID is recognized as one disk) where I am trying to put my OS. And I can create a couple of partitions - let us say I defiine a 150 GB swap, a 150 GB /, a 100 GB /var. So far so good. Then I try to define the next one, say, a 100 GB /tmp and get a message stating there is not enough disk space whereas I still have over 18 TB free and the installation interface reflects that accurately! I am at a loss. Is that something related to the sheer size of the disk? Why would this happen - especially at so basic a stage of the process? At any rate, any help or advice would be greatly appreciated. Regards, Boris. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Installing CentOS 6.2 *TO* a USB drive, not installing from USB.
On a random hunch or sheer desperation, I inserted an old brandless 1GB USB thumbdrive, installed and it booted. Thinking that the Sandisk Ultra Backup 16GB was incompatible with CentOS/grub for some unknown reason. I switched to a brandless 16GB, installed the same way and it failed at grub prompt again. Now it is starting to look as if either the newer drives have something on them that prevents booting. Or it's the total size of the drive, regardless of the partition size. I say this because in every case I used a single 1GB ext4 / partition for testing, to reduce the mkfs time. Since now I have a bootable drive, I started to compare them with fdisk to see if there was any difference. Bootable 255 heads, 63 sectors/track, 124 cylinders, start sector 63 With a warning that Partition 1 has different physical/logical endings: phys=(123, 254, 63) logical=(124, 140, 16) Unbootable 16GB Sandisk Ultra Backup 54 heads, 48 sectors/track, 12158 cylinders, start sector 2048 Unbootable 8GB Sandisk Blade 20 heads, 4 sectors/track, 195417 cylinders, start sector 2048 Unbootable 16GB Unbranded 171 heads, 40 sectors/track, 4634 cylinders, start sector 2048 It seems that the common issue is starting at sector 2048 so I fdisk the 16GB Sandisk to manually create a 1GB partition started at sector 63. Using this, I installed and was able to boot successfully. To verify, I use the same 16GB disk to install again, deleting the partition in anaconda and creating a new 1GB partition, ctrl-alt-f2 and fdisk confirms it was again at sector 2048. As a side note, for some reason, drive geometry changed for the 16GB after a reinsert to varying values such as 6 heads, 33 sectors/track, 159164 cylinders 16 heads, 32 sectors/track, 61551 cylinders Not sure if this had any significance to why anaconda decides to fdisk the drive starting from sector 2048.

[CentOS] CentOS 6.2 anaconda bug?
I have a kickstart file with the following partitioning directives: part /boot --fstype ext3 --onpart=sda1 part pv.10 --onpart=sda2 --noformat volgroup vol0 pv.10 --noformat logvol / --vgname=vol0 --name=lvol1 --useexisting --fstype=ext4 logvol /tmp --vgname=vol0 --name=lvol2 --useexisting --fstype=ext4 logvol swap --vgname=vol0 --name=lvol3 --useexisting logvol /data --vgname=vol0 --name=lvol4 --noformat The purpose is reinstalling a machine with a given partitioning scheme and preserve files on /data across the reinstall. Kickstarting a machine with these instructions, it comes up without the /data partition, it is not mounted and not in fstab. But the lvol exists and can be mounted manually, with all data preserved. /root/anaconda-ks.cfg shows the following: #part /boot --fstype=ext3 --onpart=sda1 #part pv.008002 --onpart=sda2 --noformat #volgroup vol0 --pesize=32768 --useexisting --noformat pv.008002 #logvol / --fstype=ext4 --name=lvol1 --vgname=vol0 --useexisting #logvol /tmp --fstype=ext4 --name=lvol2 --vgname=vol0 --useexisting #logvol swap --name=lvol3 --vgname=vol0 --useexisting #logvol --name=lvol4 --vgname=vol0 --useexisting --noformat I.e. the mount point was dropped.

There is no conversion, you can only backup data from partition on md0 and recreate md0 with: mdadm --create /dev/md9 --level=1 --raid-disks=2 /dev/sdj1 /dev/sdl1 --metadata=0.90 return data and reinstall grub on sda AND sdb.

We front e-end out operation with a pfSense box and it has the following mail ports open: 25, 465, 587, 110, 143, 993, 995. We have Zimbra and that also requires 7025 and 7071 be open. This sent OS Server has these same ports open and verified by 'system-config-network-tui' 1. We have a few php based sites that utilize code like: $headers = 'MIME-Version: 1.0' . \r\n; $headers .= 'Content-type: text/html; charset=iso-8859-1' . \r\n; $mail_to = slackmoeh...@gmail.com; $mail_subject = [6Colors] Footage!; $mail_body = htmlbodybr /; $mail_body = $mail_body.[6Colors - FOOTAGE]br /br /; $mail_body = $mail_body.Name: .$vName.br /; $mail_body = $mail_body.E-Mail Address: .$vEmail.br /br /; $mail_body = $mail_body.Comments: .$vComment.br /; $mail_body = $mail_body. END br /; $mail_body = $mail_body.br //body/html; mail($mail_to, $mail_subject, $mail_body, $headers); This mail is failing to be delivered. 2. We have a database backup script that e-mails a few very small databases every night. #Enter the email address you would like to receive the backup EMAIL=slackmoeh...@gmail.com; MAIL=/usr/bin/mail; /usr/bin/uuencode $DUMP$EXT2$EXT4 $DUMP$EXT2$EXT4 |$MAIL -s Mysql Backup For $DATABASE $EMAIL ; This mail is failing to be delivered. 3. We have a CMS running that we have tried using SendMail and SMTP by authenticating using Google credentials, following Google instructions and the CMS cannot send outgoing mail as well. 4. Zimbra users can send mail, but replying back doesn't work. They cannot receive e-mails.

I use DNSQueries to test this and I found they have a type for the mail.ouremail.us entry, they used .com, so I will call and have them correct it I tried doing an SMTP test on DNSqueries.com and it fails saying: I was NOT able to connect on port 25 to mail.thedigiologygroup.org I dont know if this is trying open relay stuff, so that should fail?
