Hi My system is CentOS 6. I need to edit xorg.conf. But it can't be find in /etc/X11. Where is it? How can I get the default setting? Thanks. brick ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The latest, most Wonderful (tm) version of xorg doesn't seem to require one - it does it all at boot. That being said, I think this is a stupid idea.

But, as has been said, hasn't it just been replaced by /etc/X11/xorg.conf.d/ There seems to be a general movement to replace *.conf by *conf.d/ . I'm not sure of the rationale behind this change.

With requisite the following checks are not done anymore (it fails right away). But even if the other tests succeed (after a failing required) the final judgement is still "fail". It a way not to tell the reason authentication fails. This makes it a little bit more difficult for an attacker. Note that shutdown is not in the list of pam enabled applications. So a user cannot poweroff, but he can still shutdown :-( I read that /etc/shutdown.allow controls shutdown but I don't understand what the gnome desktop actually calls. Apparently it is not poweroff/reboot/halt. Anyone knows how to properly prevent any non root user (console and remote) for powering off a machine? I need this only for desktop users that switch of their machine by accident. The machine is used as part of a compute grid as well.

And this can be the case ... they will roll back security items, but there will be some new functionality that is not rolled back. If you really need some new function, then yes, a rebuild is in order. That entails all the things I outlined above though ... figuring out "what else" you need to build first to use as a "BuildRequires", figure out what you have to build after because they depend on the built Share libraries of the package (or one they depend on one of your Newer BuildRequires that you needed). Then you need to set up a method to track all the "out of band" packages that you are adding so you keep them up2date. This can sometimes just be the package in question ... but sometimes it can be a whole bunch of other packages too ... for example, if you built a newer openssl, you would also need to rebuild all of these afterwards (which build against openssl): [hughesjr@localhost SRPMS]$ for srpms in $(ls *.src.rpm); do is_openssl=$(rpm -qp --requires $srpms | grep openssl); if [ "$is_openssl" != "" ]; then echo $srpms; fi; done authd-1.4.3-14.src.rpm autofs-5.0.1-0.rc2.163.el5.src.rpm bind-9.3.6-20.P1.el5.src.rpm bind97-9.7.0-6.P2.el5_7.4.src.rpm certmonger-0.50-3.el5.src.rpm clustermon-0.12.1-7.el5.centos.src.rpm conga-0.12.2-51.el5.centos.src.rpm crypto-utils-2.3-2.el5.src.rpm curl-7.15.5-15.el5.src.rpm cyrus-imapd-2.3.7-12.el5_7.2.src.rpm cyrus-sasl-2.1.22-5.el5_4.3.src.rpm desktop-printing-0.19-20.2.el5.src.rpm distcache-1.4.5-14.1.src.rpm dovecot-1.0.7-7.el5_7.1.src.rpm ecryptfs-utils-75-8.el5.src.rpm elinks-0.11.1-6.el5_4.1.src.rpm epic-2.4-1.src.rpm evolution-connector-2.12.3-11.el5.src.rpm evolution-data-server-1.12.3-18.el5.src.rpm exim-4.63-10.el5.src.rpm fetchmail-6.3.6-4.el5.src.rpm fipscheck-1.2.0-1.el5.src.rpm freeradius-1.1.3-1.6.el5.src.rpm freeradius2-2.1.12-3.el5.src.rpm gftp-2.0.18-3.2.2.src.rpm gnome-vfs2-2.16.2-8.el5.src.rpm hplip-1.6.7-6.el5_6.1.src.rpm hplip3-3.9.8-11.el5_6.1.src.rpm htdig-3.2.0b6-11.el5.src.rpm httpd-2.2.3-63.el5.centos.src.rpm ipsec-tools-0.6.5-14.el5_5.5.src.rpm iscsi-initiator-utils-6.2.0.872-13.el5.src.rpm isns-utils-0.93-1.0.el5.src.rpm java-1.6.0-openjdk-1.6.0.0-1.24.1.10.4.el5.src.rpm kdelibs-3.5.4-26.el5.centos.1.src.rpm kdenetwork-3.5.4-13.el5_6.1.src.rpm libc-client-2004g-2.2.1.src.rpm libdbi-drivers-0.8.1a-1.2.2.src.rpm libgnomeprint22-2.12.1-10.el5.src.rpm libwvstreams-4.2.2-2.1.src.rpm lynx-2.8.5-28.1.el5_2.1.src.rpm m2crypto-0.16-8.el5.src.rpm mod_authz_ldap-0.26-11.el5.src.rpm mutt-1.4.2.2-3.0.2.el5.src.rpm mysql-5.0.77-4.el5_6.6.src.rpm neon-0.25.5-10.el5_4.1.src.rpm net-snmp-5.3.2.2-17.el5.src.rpm NetworkManager-0.7.0-13.el5.src.rpm nmap-4.11-2.src.rpm nss_ldap-253-49.el5.src.rpm ntp-4.2.2p1-15.el5.centos.1.src.rpm openCryptoki-2.2.4-25.el5.src.rpm openhpi-2.14.0-5.el5.src.rpm OpenIPMI-2.0.16-12.el5.src.rpm openldap-2.3.43-25.el5.src.rpm openldap24-libs-2.4.23-5.el5.src.rpm openssh-4.3p2-82.el5.src.rpm pam_ccreds-3-5.src.rpm perl-Crypt-SSLeay-0.51-11.el5.src.rpm perl-Net-SSLeay-1.30-4.fc6.src.rpm php-5.1.6-32.el5.src.rpm php53-5.3.3-5.el5.src.rpm postfix-2.3.3-2.3.el5_6.src.rpm postgresql-8.1.23-1.el5_7.3.src.rpm postgresql84-

FC-16 boots just fine on two different laptops each with an external monitor attached. On the work system Xorg auto-detects the monitor configuration and just works. On my older laptop at home I have to run xrandr to get it to sort out which display is where. The work laptop is all Intel including the video and the home laptop has an AMD CPU and ATI graphics plus the display geometries are different for both the laptops and the external monitors. I appreciate that this is with FC-16 instead of CentOS but you may find that the autoconfiguration will work this well when RHEL/CentOS 7 gets built based on FC. It's really nice to just be carrying the external disk between work and home instead of the laptop.

[CentOS] RAID-10 vs Nested (RAID-0 on 2x RAID-1s)
Greetings- I'm about to embark on a new installation of Centos 6 x64 on 4x SATA HDDs. The plan is to use RAID-10 as a nice combo between data security (RAID1) and speed (RAID0). However, I'm finding either a lack of raw information on the topic, or I'm having a mental issue preventing the osmosis of the implementation into my brain. Option #1: My understanding of RAID10 using 4 drives (now known as a,b,c,d) is: a+b - RAID1 (md0) c+d - RAID1 (md1) md0+md1 - RAID0 (md3) This is of course simplified as /boot needs to be on RAID1 (last I checked Grub couldn't boot from anything other than RAID1). Option #2: I've also found the kernel provides a direct method of RAID10 without the manual assignment of the arrays as noted above. I performed a test installation, selecting RAID10 as the type in the installer, and it "works" but I'm just not seeing the distinction between what disks/partitions are actually the mirror or stripe portion of the array. Details: [root@c6r10tester ~]# mdadm --detail /dev/md1 /dev/md1: Version : 1.1 Creation Time : Thu Mar 29 16:14:17 2012 Raid Level : raid10 Array Size : 36695040 (35.00 GiB 37.58 GB) Used Dev Size : 18347520 (17.50 GiB 18.79 GB) Raid Devices : 4 Total Devices : 4 Persistence : Superblock is persistent Intent Bitmap : Internal Update Time : Thu Mar 29 16:28:49 2012 State : active Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : near=2 Chunk Size : 512K Name : c6r10tester:1 (local to host c6r10tester) UUID : be38645d:4d3c8b77:0f6df687:08016c6a Events : 51 Number Major Minor RaidDevice State 0 830 active sync /dev/sda3 1 8 191 active sync /dev/sdb3 2 8 352 active sync /dev/sdc3 3 8 513 active sync /dev/sdd3 Am I overthinking this? Does the kernel handle the mirror/stripe configuration under the hood, simply presenting me with a magical RAID10 array? Or, is this something different and I really should be performing the RAID creation manually as noted in option #1?

[CentOS] my spammer list
Hello, Thanks to some nice people on here and other forums I have pretty much finalized my whole mail system on centos 6.x. With all the checks, greylisting, dev/null of any 8+ spam level SA, I still get a few mails. It seems like everytime I enable a new protectant, the mail stops spamming for a few hours...then the spammers decide I am worthy of using better methods against me..and more come. LOL. I am down to just 10-15 a day. Anything that gets through all that I set up now goes to a spammers list that I add to the access file of postfix. http://bobhoffman.com/spammers.html that is the link to my list. I am trying to sort them out into political, real estate, bulk spammers, etc. The worst part is the bulk emailers are not on any black list. It is very hard to find their mail MX until they actually send you one. Many will be blocked, then a new alternate of theirs comes through. I could not find a list of bulk commercial spammers so I thought I would start one. As I progress it will become more defined, but right now a big list with some categories after it. Hope it helps. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Two resources to look at are: 1) Wikipedia "Linux MD RAID 10" http://en.wikipedia.org/wiki/Non-standard_RAID_levels#Linux_MD_RAID_10 2) mdadm manpage section for --layout= (the raid10 part) "Finally, the layout options for RAID10 are one of ’n’, ’o’ or ’f’..." The key to understanding your setup is mdadm --detail "Layout: near=2". The cited Wikipedia reference for a "standard near layout" describes your situation.

[CentOS] Linux on touch screen device
I have poked around in google and have seen a number of youtube videos, but my question is whether anyone really has linux running on any kind of tablet or tablet PC device in such a way that the touch screen can be used productively and it won't take a month to get it running? 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. Nataraj ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I used to do something very similar to option 1, save that I used LVM to do the striping. I now use the md raid10 array. Rebuilds are dramatically faster under the 'just let md handle the raid10' option. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Sometimes I can recognize them by seeing the same spams repeatedly, also, different IP addresses connecting and guessing passwords for the same list of users. But I rarely get those anymore since I have blocked pop/imap logins from outside of the US. You can report them to spamcop.net and that may help to provide some incentive for ISPs to kick spammers off their network. The way that I finally got rid of all the residual spam that makes it through greylisting, SPF, spamassassin, clamav is to handout unique mail addresses and use black/whitelists. So for example if I assign an email address for incoming mail from a mailing list and then setup a whitelist entry that only allows that address to receive email from the mailservers that serve that mailing list and then blacklist all other incoming mail to that address it is very effective. With a decent whitelist/blacklist tool it's fairly easy to implement. I used to get literally hundreds of spams a day and now I probably average about 2 per week. You can also get on the spamassassin mailing list and add more plugins and work on tuning the spamassassin config. You can also play with sa-learn. For me though the black/whitelisting works quite well. Nataraj ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Usually spam dev/null them but decided to disable spam assassin and go after a nice list. Only got two mails in the last 12 hours, so it is cool. I get lots of political and real estate spammers due to the jobs I have had and my mail being on their lists...a list you can never get off. So listing them was the perfect thing. so without spamassassin, going good so far. Almost nothing. when I get one or two a day I just add them to the list..lol I am happy to not have hundreds a day anymore...so happy. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

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

Thank you. I am aware of android, but my understanding is that the libraries are changed enough that it's not that easy to build random linux software that hasn't been ported. My interests in running linux on a tablet is influenced by: - ability to eventually run wide range of open source linux software, scripting languages like perl, python - privacy issues, prefer not to run software that forces you to allow companies to track keystrokes/location - ability to implement and verify my own security, i.e. my own iptables rules - ability to integrate well into my existing linux based network, i.e. ipad doesn't do this so well > 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. I pinged this list because I find there is alot of diversity on list and I value the experience that people share here. I am not attached to CentOS and I do run several distros myself. I've seen some threads where people went out and bought devices and never got the touchpad working. In some cases some people got things working and then the manufacturer changed the firmware in later versions and suddenly people that bought them couldn't get them to work. > Go ask over at Fedora, Ubuntu and maybe Mint.

I can see though where some desktops/user interfaces will provide a very different user experience than others on a touchpad and similarly for a desktop. I tried unity about 1.5 yrs ago and was very unimpressed using it on a desktop, but it might be good on a tablet.

I'm aware that people do get these linux ports up and running on arm devices, but essentially what I am asking here is if I went out and bought any particular arm device, Asus transformer prime, galaxy etc, what's the likelyhood that your port includes a device driver that will work well with the touch screen? I looked at your website a few days ago and saw the low power arm appliance devices, but didn't see anything about supported touch screen devices. nataraj ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
