We also had it updated and fail2ban worked perfectly except it did not
ban anymore on the sshd jail. This was caused by the
/etc/fail2ban/filter.d/sshd.conf file which should have been replaced
with a new one from the rpm (there was a sshd.conf.rpmnew file).
Below the error we found in /var/log/fail2ban.log :

Re: [CentOS] rescue - UEFI revert to BIOS boot - how?
Hi, I had the same sort of issue. My workstation with a Asrock motherboard suddenly decided to reset UEFI to defaults which caused my Fedora installation not to boot. I could boot with a Live USB stick and use efibootmgr to set the UEFI boot for Fedora but next time I powered on my machine the same issue happened (I remove AC power from my workstation when it is not in use). Turned out to be a flat battery for the BIOS (coin cell). I replaced the coin cell and set the UEFI boot with the Live USB stick and all was well. The efibootmgr command was something like : efibootmgr -c --part 2 --loader /EFI/Fedora/grubx64.efi --label Fedora Please check the manpage of efibootmgr, the process of how to setup the UEFI boot is described very well.

Re: [CentOS] kde in centos 6.4
On the login screen there was no place as in 5.9 or older to make a choice of desktop environment. I changed DESKTOP=KDE DISPLAYMANAGER=KDE and it has no effect; GNOME hang on there. So because of a lot of flaws in my installation and of lack of time I decide to go back to 5.9 and get a look later for a 6.4 installation. --- Michel Donais - Original Michel, are you trying to change your window manager (gdm vs kdm) or your desktop (gnome vs kde)? If you are trying to change your desktop, then Craig's suggestion would work, though keep in mind that the session section of the gdm window manager is on the password screen, i.e. you enter your username and then you have the option to change your desktop on the next screen. Like Mark said, they don't make it easy, meh! If you are trying to change the window manager itself, as in have kdm handle the login screen rather than gdm, then you would need to create the file /etc/sysconfig/desktop and put these two lines in that file: DESKTOP=KDE DISPLAYMANAGER=KDE then reboot the machine and it should come back up with the kdm console screen (and the system default desktop set to kde). Keep in mind that you may need to explicitly install the yum group KDE-Desktop in order to set the window manager to kdm. Depending on which type of os install you did, that group doesn't get installed. For example, for my workstations we generally use the install choice Software Development Workstation, and we need to do a yum-install of the group after the os installation is finished (since we don't bother with the customization stuff until post-install). Hope this helps!

Hi Michel. This is only to print a sys variable; you don't need to do anything there.

Initially the two applications that are of most interest to me would be a good web browser (maybe chromium) and thunderbird. I would also like to have a decent on screen keyboard which could be used to ssh to servers in an emergency. I've seen instructions for booting linux on various devices, but many people doing this are using keyboards and not touchscreens. Do applications like thunderbird have to be modified in order to work well with a touch screen or is just getting a working driver for the touchpad sufficient? If anyone has any experience with this I would appreciate knowing what hardware your running on and what linux distro/desktop environment you use. I've been interested in devices like the ASUS EP121 which is a dual core I5, so it wouldn't be necessary to have an ARM distribution. Also the newest Asus transformer prime (arm) which I think is about 2 months away sounds interesting. Lots of people do this and lots of (most?) commercial tablet/smartphone systems are based on Linux or a close cousin (Android and iOS come to mind...). As far as non-commercial DIY tablet distros, there are distros and special interest groups within larger distros that focus on this type of deployment. But none of them are CentOS, so I'm not sure why you pinged this mailinglist -- though I think you'd probably find that CentOS installs just fine in most cases, just remember to build whatever graphcs driver you need or your experience might not be good. Go ask over at Fedora, Ubuntu and maybe Mint. Also check out MeeGo and whatnot. As a side note, there is nothing magical about a touchscreen. Touchscreens are just pointing devices like mice and touchpads as far as Linux is concerned, but in this case it is a touchpad that you can see through to a screen on the other side (there is a special case of location logic, of course, so the pointer doesn't continue from last location, but this is a normal case handled by X). So nothing special happens in an application to make it work with a touchscreen because a touchscreen is just creating mouse events the same way your normal mouse would do. The only problem with touchscreens is that small icons are smaller than your finger (well, mine anyway) and so you have to make the desktop a little cartoony to make things work right. Gnome Shell in Fedora is actually not too bad to use with a touchscreen, though it sucks horribly with a mouse IMO, and KDE with large widgets is pretty easy as well. -IY ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Hi, Did you configure corosync ? Normally corosync starts pacemaker, which in turn starts the heartbeat deamons. But you have to configure the latter using for example a pcmk file with configuration in /etc/corosync/conf.d/ (from the top of my head). I normally use : http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Clusters_from_Scratch/ Regards, Michel On Wed, 2011-11-23 at 12:16 -0500, Hal Martin wrote: Hello all, I am trying to create a corosync/pacemaker cluster using CentOS 6.0.

You first need to double-check that /dev/ttyS0 is actually the correct serial COM port you have the modem connected to. Please look under System-Hardware and then click the 16550A-compatible COM port in the LH pane. Then in the RH pane click on 'Advanced', and find the serial.device string or linux.device_file. This will be something like: linux.device_file strlist /dev/ttySx where x == 0|1|2|3 serial.device strlist /dev/ttySx where x == 0|1|2|3 Make sure this is the same as what you are trying to connect to.

Found it with 8 partition; boot was there but nothing of the operating system to load Linux 5.6 My recovery solution was to put the disk on a window system as a secondary drive. Just connected to read data For reading I found a software called ' nucleus kernel linux' from http://www.nucleustechnologies.com/Linux-Data-Recovery-Software.html On partition 3 I found nearly all my data files and their directories but were missiing /etc /bin /dev Hope this help. --- Michel Donais ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] big problem at boot [SOLVED]
Than's a lot everybody who answered my help request. You just give me a way to search finding a solution. I noticed that the on the disk the boot sector was there and permit booting but the system failed because was'nt able to find /etc/inittab. That let me think that perhaps it was ok on the rest of the surface. I found a Windows software (sorry) named 'Neucleus Kernel Linux' by http://www.nucleustechnologies.com/ With it I was able to scan the surface of the disk and recover all my lost files. --- Michel Donais ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] cent0s-6 and virtualbox
Hrrm, seems as if the ISO may be using a PAE kernel by default. PAE is a kernel that will be able to make use of more than 4GB of RAM with i686. Ah, I see it's apparently a decision by RH. I assume there's some logic in it, though I don't know what it is. http://jp.centos.org/modules/newbb/viewtopic.php?topic_id=26352forum=14 See if it's possible to add PAE to the machine settings in VirtualBox. Settings=System=Processor The box is already checked but the CPU doesn't have PAE capability so it's useless. It won't be a bad thing thatthe install may do a choice of a cpu with or not the capability of PAE as it was in the past. --- Michel Donais ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] tar-ing subdirectories separately
Hi, I want to backup a directory using tar, but want separate tarballs for each subdirectory. For example: # ls dir1 subdir1 subdir2 subdir3 Will it possible to do it using only tar command? Or will I need another separate piece of logic/control? I thought of writing a shell script with three tar commands for each subdirectory, but that's not elegant way of doing it. Also, it may not scale as number of subdirectories change. Any other solutions or tips for doing this will be really helpful. You can try something like : find /dir1 -type d -print -maxdepth 0 | while read DIR ; do tar cfv $DIR.tar $DIR/; done not tested, just off the top of my head and it's late, so if it breaks, you can keep and be happy with all the pieces ;) Regards, Michel ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I've seen the DVD ISO files on select mirrors. it can be difficult to reliably transfer a 4GB file over http/ftp I've only had one DVD iso dowload corrupted over http. I use a fast mirror and d/l overnight with a wget bash script, run by cron. I have downloaded hundreds of DVD iso images with wget and curl during the past years. I had maybe one or two that were corrupted in one way or another, mostly because of improperly configured (windows) webservers. 4Gb with HTTP is no problem nowadays, FTP isn't either. If you have doubts about HTTP/FTP you can always use the Bittorrent way to download (also with commandline tools like btdownloadcurses or similar). It doesn't really matter when you download them although in some cases it can make a difference in speed to download overnight but with most tools you can also specify a maximum bandwith to use. To be sure an image is ok you can always check the image with the md5/sha1 checksum which is normally found in the same directory as the image on the HTTP/FTP server. kind regards, Michel ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If you should use them in a PCI slot yes, not if you use them in a PCI-X or PCI-e slot (although you could saturate a PCI-e x1 with 4 gbit ports I think). Depends mostly on if you are using PCI/PCI-X vs PCI-express. At high bit rates you can saturate the old PCI bus. A single gigabit port can pretty much saturate a 32-bit PCI bus at 33MHz. PCI-express can go a lot faster. The Intel Quad cards don't fit (and don't then) in a single PCI slot.

Que pueden decirme al respecto? Slds Michel Michel y demás hermanos, migrar un AD no es sencillo si se desea migrar a los usuarios sin tener que pasar a re-establecer su contraseña (yo he pasado por eso y es bastante pesado). Yo tengo poca experiencia en estos temas, lo que puedo aportar es lo siguiente: Monta un Fedora (ahora 389) Directory Server (los paquetes están en el Repo de EPEL y Alcance Libre), el proceso de instalación es sencillo. Luego de que tengas todo OK, entonces procede a crear el certificado para asegurar tus conexiones LDAP (por el puerto 686) y especifícale en el servidor que solamente acepte conexiones seguras, en el lado del cliente ejecutas openssl con algunas opciones y apuntando al puerto 686 del servidor LDAP para extraerle el certificado al mismo para que el cliente se conecte sin problemas, claro está que tendrías que configurar el cliente LDAP después. Luego asegúrate que tu W2K3 tenga su Entidad Emisora de Certificados y su AD tenga su certificado. Si todo está OK, entonces tiene que obtener ambos certificados (en el Wincows es un .pki y en el Linux es un .p12 si la memoria no me falla) para añadirlos a ambos servidores. Con esto hecho tienes que establecer un Acuerdo de Sincronización en el 389DS para así poder sincronizar el 389 con los usuarios del AD. Si todo lo anterior es exitoso, tienes que montar en en Windows el PassSync y configurarlo para que en cuanto haya algún cambio de contraseña por parte de un usuario, pues, que el PassSync la capture y se la mande al 389DS (esto es debido a que la función de Hash de los passwords en Wincows no es igual a la de Linux y, dicho sea de paso, el password no se guarda en la entrada del usuario en el AD), hay varios modos de forzar a los usuarios a que cambien sus pass, uno de ellos (el que más me gusta) es por las políticas de cambio de pass. Una vez obtenidos todos los datos de los usuarios, entonces es que montar en tu Linux el smbldap-tools. Claro, entre un amigo y yo lo modificamos (sin saber ni K de phyton ni perl) para que convirtiera las entradas ntUser obtenidas del AD en entradas posixAccount y sambaSAMAccount para que nos pudieran servir para los usuarios (se imaginas casi 1000 usuarios pasando por el sistema para poner contraseñas, un verdadero dolor de cabeza).

He podido ver que existe un proyecto que ya me mencionaron en un correo, Directory Server el mismo esta disponible en el repositorio de CentOS , en la seccion de Extras. me pregunto si alguien quizas lo tenga implementado y funcionando desde algun tiempo, que pueda darme sus referencias y opiniones. http://wiki.centos.org/HowTos/DirectoryServerSetup Creo que el mayor problema es la migracion o manejo de las politicas. Que pueden decirme al respecto?

Re: [CentOS] need help: about remove space

I need it as fileB and then wc -l fileB. If those lines between the names are empty lines you might try : cat bigfile | egrep -v '^$' | wc -l or if you want the names into a second file : cat bigfile | egrep -v '^$' fileB Regards, Michel ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Using Wireshark on CentOS without UI
Hi, Yesterday i had installed wireshark on my centos box which does not have the GUI , It is actually a hardened box. I installed the tool using the following command: yum install wireshark After installation i dont know how to proceed further in capturing the packets. I basically want to capture packets and copy them onto my windows box. On the windows box i can use the Wireshark UI to open the pcap file to view its contents. Wireshark in cli mode is called tshark. With 'tshark -i eth0 -w outfile' captures all traffic on eth0 to outfile.
