[CentOS] Suggested yum priorities settings for 3rd party repos
In the yum priorities page on the wiki Akemi Yagi suggests http://wiki.centos.org/PackageManagement/Yum/Priorities [base], [addons], [updates], [extras] ... priority=1 [centosplus],[contrib] ... priority=2 Third Party Repos ... priority=N (where N is 10 and based on your preference) If you have rpmforge, kbs, epel all set up at 10 then wouldn't those also potentially overwrite each other if the same package exists in all of them?

[CentOS] HAL automount luks device
Hi all, I have set up an encrypted partition on a usb key and can now successfully mount it using: cryptsetup luksOpen /dev/DEVICENODE cryptousb mount /dev/mapper/cryptousb /mountpoint My aim is now to do this using HAL and GNOME's Luks integration. I am already asked for the pass phrase after plugging in the device, but I seem to be not allowed to mount it. Do I need to add an fstab entry for the crypto container? Or do I need to modify some udev rules to allow unprivileged users to mount the container? Best Regards Marcus ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Missing grub functionality on CentOS 5
There's grub 0.97 on CentOS 5. The manual at http://www.gnu.org/software/grub/manual/html_node/index.html says it is for 0.97. However, it mentions for instance a program grub-set-default that is not present in grub-0.97-13.2. It also mentions grub.conf options savedefault and fallback. Are these available in the CentOS grub? I tried with savedefault and it does not create a /boot/grub/default as it should. So I have to assume that fallback isn't there either. The CentOS 5 grub is the same as the CentOS 4 grub and I would assume that it's the latest legacy grub, so it should include all that. Anyone knows why it doesn't? Anyone knows if it includes savedefault and fallback functionality? If so, how to make use of it? I downloaded the source and built (but not installed) it, that includes a grub-set-default file. I created a default file with it, but it's still not getting used by savedefault. So I must assume the functionality is not built in the CentOS grub.

It is just addresses that are mapped, there is no physical copying of memory that you had with EMS memory. Generally, PAE would not make much sense on 16GB memory machines, as you still need the space in the 4GB range to address it. Personally I would use PAE on machines with up to 8-12GB memory (assuming x86_64 wasn't an option). With more than 16GB I would recommend against it, as you get a lot of remapping and/or limited space in the 4GB range.

If you have say webmin from webmin.com and there is webmin in all those repos then it might be good to use exclude but shouldn't the plugin handle versions between repos?

It is just addresses that are mapped, there is no physical copying of memory that you had with EMS memory. thats not at all an accurate description (other than the 64GB part) ALL virtual memory systems use page tables to map virtual addresses to physical addresses. x86 systems (and many others) use a 2-level page table where a the high bits of a virtual address is used to look up a page table entry in the page directory, then this in turn is used with middle address bits to look up an actual physical page address.in 32bit x86, this system allows addressing 4GB of physical memory for as many 4GB virtual address spaces as you care to maintain tables for.. the page directory and each page table occupies a single 4K page of memory, which holds 1024 entries of 32 bits each. a process that uses a full 4GB of virtual would require the 1 4K page directory and 1024 4K page tables (although in Linux systems the top 1GB of the 4GB address space is the kernel space, which is shared by all processes). in practice, most page directories and page tables are only partially populated as most processes only use a small part of their address space. PAE uses a modified page table where each page table instead has 512 x 64bit entries, which provide the larger physical address bits, and it adds a 3rd level page directory so each page fault has to go through three levels of page tables rather than two. (side note, this is assuming 4K pages... x86 also supports 4M pages, which reduce the lookups by one level, however, I don't think this is used much) see http://en.wikipedia.org/wiki/Physical_Address_Extension#Page_table_structures for a pretty good summary of this. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It should not be writable for other users, and permissions should be 644. Now I had a look at this ~/.dmrc, and permissions were rw---. So I did a chmod 644 on it (rw-r--r--) and logged back out... but the problem still persists. I'm puzzled. Any suggestions?

Suddenly my user's home directory went from 700 to 777. I chmodded it back to 700, and now everything seems alright. I had a power outage this night, and I have no other explanation that my home directory mysteriously changed permissions.

[CentOS] Is 4GB memory the 64bit switch tipping point?
I am curious what should be the benchmark for making the choice of switching from 32bit to 64bit Linux? I have a few assumptions below. Is my logic sound? (This is a follow up to the Adding RAM thread) Assumptions: 1. 4GB Memory. The main benefit of 64bit mode is the ability to address more than 4GB of RAM. I assume that you use 64bit mode if you want to *efficiently* have more than 4GB of RAM, or intend to upgrade past 4GB in the foreseeable future. (I emphasize efficiently because PAE is an option, if you are desperate to keep 32bit mode with more RAM) 2. Overhead. It is my assumption that 64bit has more overhead, being that the registers are now 64bits long, instead of 32bit, which would mean more bits to pass around the system. So if you have less than 4GB of RAM, 32bit mode would perform better than 64bit mode. 3. Compatibility. Linux has made incredible strides to make 64bit Linux very robust and compatible, but I still occasionally see binary applications/plugins/drivers that popup which are 32bit mode only. This is usually only a problem with Desktop systems that want bleeding edge, or not as well supported software. 4. Desktop vs Servers. Current desktops machines generally have around 2GB of RAM, or less. Current server machines generally have around 2GB of RAM, or more (much more). Because of the overhead (#2) and compatibility (#3) I would think that Desktops would benefit from using 32bit mode, and Servers would benefit from 64bit mode. Is my logic sound?

On CentOS and RHEL, telnet is launched by xinetd and is governed by the instances limit in the /etc/xinetd.conf file. Change the limit and use service xinetd reload to reload the config file.

Hi everyone, By Now, I have solved this issue. yes, /etc/xinetd.conf is the file.

Number 2 is solid. Number 3 is... mostly irrelevant with CentOS. Number 4 is not specific enough. First, The 4GB limit. Yes, 64-bit allows the OS access to more than 4GB of *physical* memory. However, it *also* allows (64-bit) processes to access more than 4GB of *virtual* memory. This can be invaluable in applications that process a lot of data. Second, compatibility. Upstream's use of multilib allows 32-bit applications to be run on a 64-bit system without much trouble. Plugins, specifically Firefox plugins, have the better part of a solution in the form of nspluginwrapper. Drivers not much can be done about; fortunately there aren't too many of those. Third, desktop versus server. Let's ignore the 4GB limit discussed above while we examine this one. For PPC versus PPC64 your argument is valid. For IA-32 versus X86-64, you need to look at what the desktop will be used for. One of the benefits X86-64 gives you over IA-32 is more registers within the CPU. Operations involving registers are *much* faster than operations involving memory, allowing X86-64 apps to be up to about 15% faster than IA-32 in mathematical, scientific, or multimedia applications. -- Ignacio Vazquez-Abrams [EMAIL PROTECTED] PLEASE don't CC me; I'm already subscribed signature.asc Description: This is a digitally signed message part ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Mirroring Hard Drive
2008/12/8 William L. Maltby [EMAIL PROTECTED]: Yep. I've recently began using rsync for several types of local copy, usually back-up related. I can't recall if the cp -a detects and handles hard-links to minimize space requirements though. I know cpio Yes, it seems that cp -a is designed just for that kind of job. Might have to add -x to limit it to one file system if you are interested. I noticed that, to my surprise, rsync is sometimes faster than a plain scp even when the destination is empty, and as someone else said it's nice to be able to stop/start and redo. can/does. I guess I'll have to read up on cp some more and see if it leaves the access times alone (cpio parameter allows retaining that) and handles hard-links efficiently. I'm not sure why you should care about atime so much - more and more people around (including Linus Torvalds) recommend to get rid of it altogether. Ubunut comes with relatime as a default config already. According to Linus, disabling atime updates will give the single largest performance gain (in dozens of percentages, as far as I remember). But back to the question - am I missing something too by not using dump/restore or cpio? dump/restore is so BSD 4/'80's :) Cheers, --Amos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
