Re: Squeeze X86 with 4GByte RAM?
Dear Users, I installed 4GByte RAM in my motherboard succesfully. In BIOS I see all the 4096MByte, but after booting Squeeze it show me 3,5GByte. I know I should install the kernel with PAE - so I installed linux-image-2.6.32-5-686-bigmem package and restart computer. After it I choose this new kernel from GRUB. After loading it stuck with black screen with blanking cursor on the top left side of the screen. What should I do? Squeeze i386 has an amd64 kernel. The command apt-cache search linux-image will show you all the possible kernels. Choose some -amd64, for example: apt-get install linux-image-2.6.32-5-amd64 Then you will have a 64bit kernel and 32bit userspace, there is nothing wrong with this.

Re: multi-core system and the file system
Hello, I would like to ask, whether there is some intelligent way how to synchronize processes over the file-system state. E.g., if one process creates|modifies|deletes some file, how can I learn *when* that effect hits all cores? (not just the one where I executed those operations) I don't think the question makes sense. Changes in the filesystem affect processes, not cores. Processes are aware of filesystem changes as soon as they do some filesystem related system call, like stat(), readdir() or read() over an inotify watch descriptor, irrespective of the core in which they are running at the moment of the system call. Thanks in advance for any clues. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Re: has your squeeze ever crashed?
linux is stable, or is it? Absolutely stable and crashproof? No. Anyone who says that has no idea what he is talking about. You can compare Linux operating systems to other operating systems if you wish, though. my squeeze has just crashed it doesn't respond to key press two of three lights in up right corner of keyboard blink Squeeze is now more than 2 years old and in this period I installed and administered dozens of debian computers. I had the oportunity to see lots of crashes not caused by hardware failure, almost all of them related to video or wifi drivers, i.e. still related to hardware. I don't recall to find any purely algorithmic kernel crash or panic in the last few years. I suspect flash player in browser might be the cause the player is downloaded from adobe site and installed by myself besides I often see XID collision, trouble ahead though it rarely cause problem I don't think so. Flashplayer is a completely user space program and as such it could completely lock the system up only if there was a kernel bug. I had and still have a lot o trouble with flashplayer, like it consuming all of the memory and processing, but I almost always could go to Control-Alt-F1, log in and kill it, apart from the times where the system was heavily thrashing (completely busy swaping memory) and I had no patience or hope to wait. This does not seem your to be your case, as the keyboard lights usually indicate a kernel problem. I yould bet some device driver or hardware failure (memory or hard disk).

By kernel logs or experimentation and reproduction. The Linux algorithmic errors usually leave nice error messages before the system freeze (BUG_ON etc). I'm no kernel expert, but as I understand it, it's basically a layer between applications and hardware. From that point of view, error in kernel not related to hardware seems to me as a rare (if not impossible) thing... No, the kernel has very complex algorithms to deal with process and memory management, filesystems, networking etc. Run -rc1 kernels and you will eventually find bugs in such subsystems. The kernel sure is a layer as you said, but it is also an abstraction layer so that you don't have to implement basic and common features. I don't mean to bicker, I'm just wondering if it would make any sense to divide kernel code that is more closely related to hardware (like drivers) and more generic code, in attempt to measure stability of these parts separately. There are the so called microkernels that work this way. Linux is not a microkernel (it is a monolithic kernel). This is a very long discussion that periodically comes back (see Linus - Tanenbaum debate if you really want learn about it).

If this is the case, try an fstab line like /dev/sd?? /media/vfat vfat defaults,umask=0007,uid=User,gid=User 0 0 which grants permission for User.

I've a collection of USB flash drives which, when plugged into a running Debian 6.0.5 system, do not mount in an apparently uniform manner. The various drives may have been formatted: 1. by WinXP Pro SP3 as FAT16, FAT32, or NTFS 2. by gparted under Debian 6.0.5 as ext???, FAT16, FAT32, or NTFS 3. by the stand alone Live version of gparted as in #2 I don't have any current examples so I can not ask an answerable specific question. Note that ext2, 3 and 4 don't support umask, uid and gid mount options, so even user mounts (or mounts via dbus) cannot overwrite the filesystem permissions. Note that sometimes a file or directory is created in a removable device within an ext{2,3,4} filesystem under some user joe in one computer and people expects that joe can access this file or directory in every computer, but this may not happen, as joe can have different user ids in different computers. Filesystems store the user id, not the username. If you want an ext{2,3,4} filesystem to accessible by everyone in every computer, there is a workaround: change its root permissions to those of the tmp directory. To do so, as root, mount the filesystem in some directory (say /mnt), do the command chmod 1777 /mnt/ and umount /mnt. Could someone point me to a broad intermediate level survey of permissions (issues and implications) in order that when (not if) I run into a problem I'll be able to ask an intelligent question?

When grub gets to be installed, in the last installation step, all the information that an iso existed before is gone, or no? When the isohybrid ISO is written to to the drive the information about the iso9660 filesystem is put within the first 65 sectors of the drive. If fdisk is now used to partition the drive the first partition starts at sector 2048. Everything beyond this sector is destroyed but sectors below number 2048 are left intact. The drive is now useless as a device to boot Debian but information about the iso9660 file system is left intact. Wow, of course. The iso image must be installed in the begining of the disk, which includes the partition table and the mbr, not in the first partition. fdisk leaves space at the beginning of the drive because GRUB requires it to embed part of itself there. But GRUB will not go there because it thinks it is overwriting data on the disk when it detects the iso9660 signature. This is by design. This is clearly a bug, because the disk has a partition table and therefore there is no useful data before the first partition. D-I uses partman for partitioning. It too leaves an embedding area which contains the iso9660 data sector. The solution is to remember to do dd if=/dev/zero of=/dev/sdX count=65 before partitioning. But this will destroy the partition table, which is not right if you have other operating systems or partitions containing data. Maybe 'grub-install --force device' would suffice? Anyway, it must be said that you did an impressive investigation with very scarce resources to say the least, Brian! Thanks. I cheated though!

It is possible that you have different grub configurations in each HD and the BIOS is choosing a different disk to boot from each time.

Re: Package Pre-dependencies
Hello everyone, One quick question: If package A pre-depends on package B, and package C depends on package A, does package C pre-depend on package B? In other words, is pre-depends transitive across regular dependencies? C ==(Depends)== A ==(Pre-Depends)== B As you stated the problem, if package C does not explicitly pre-depend on package B, then in the course of installation of packages A, B and C, the package C can be unpacked even if B is not unpacked nor configured. Only A must wait until B is fully configured in order to be unpacked. Here you can find the policy for these package fields: http://www.debian.org/doc/debian-policy/ch-relationships.html So, no. C does not pre-depend on B unless it is explictly stated in its Pre-depends field. Here is an example: bash ==(Depends)== base-files ==(Pre-Depends)== awk.

Here is an example: bash ==(Depends)== base-files ==(Pre-Depends)== awk. Thanks - that's what I suspected but it wasn't entirely clear when I was reading it. The problem I have is that many packages install files into a directory that in a real environment is actually a symlink to a different directory created by the base package. If they are unpacked before the other package then things break The only two options I see are for the packages to explicitly pre-depend on that package OR for each package to manually move all of the installed files into the actual directory in their debian/rules. Listing a pre-dependency for each package thus seems a less pessimal solution. But am I missing something here? Is there a better solution? This seems a fair use case. Note that if the symlink does not exist, a hierarchy of directories is created automatically by dpkg to accommodate the files, and the installation process will not explicitly fail. Therefore, the solution of a package that creates symlinks that serve as filesystem structure for other packages is not very robust, as symlinks are easily removable (by administration errors).

Rodrigo, we cannot help if you don't tell what is the exact model of the network card. Type the command lspci -vnn in the running Debian and copy the lines about the ethernet controller. What Is happening ? Most probably your network card is not supported by the kernel 2.6.32 that comes with debian 6. Let me suggest that you install a testing version of Debian (version 7, Wheeze). This version is close to stable. It will probably detect your network card and also will save you from having to upgrade the system during the next 4 years. Here you can find the testing images: http://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-cd/ or http://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-dvd/ However, if you insist in running Debhian stable, you could try to install a full cdrom or dvd image (not netinst) and then download and install the kernel 3.2 from Debian backports. Here you can find the package: http://packages.debian.org/squeeze-backports/linux-image-3.2.0-0.bpo.4-amd64 You have to download this package and the packages of the dependencies, and install them with dpkg. For example: dpkg --install linux-image-3.2.0-0.bpo.4-amd64_3.2.35-2~bpo60+1_amd64.deb This command must be done as root. When you do this command, probably the installer will complain of a missing dependency. Then you go back to http://packages.debian.org/squeeze-backports/linux-image-3.2.0-0.bpo.4-amd64 find the dependency package, download and install with dpkg and then do the command dpkg --configure -a Repeat this this untill everything install OK, reboot the system and choose the kernel 3.2.0.

Ah, yes. Windows had such a switcher addin about 20 years ago. I don't know if some people in the list fall for the trick, but he is definitely using it. He uses other tricks too, like saying that he will accept anyone's suggestion but from person X. Then everybody starts to work for him, including person X who has remorses.

Re: fix HD order
Hi, i've 4 HD's and 3 distros. When i load debian squeeze, the sdc hd is slected by grub, but the next time i load it, the sda hd is selected. It seems a randomize selecting. How can i fix this ? UID is used and settings by name don't resolve the problem. And yes, i have win7 also on a separate hd. thanks Do you always see the same grub menu when booting? It is possible that you have different grub configurations in each HD and the BIOS is choosing a different disk to boot from each time. I would try to make sure that the bios always choose the same disk when booting. If this is not possible, then all files /boot/grub/grub.cfg in each HD should be equal and use UUIDs. Also, make sure that the /etc/fstab in each distribution use UUIDs. João Luis -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

This didn't start out as my thread. I wish to advocate linux is not my aim. I merely made a comment about Linux advocacy and got jumped on. If you dont care about Linux advocacy, why did you comment here? This kind of contradiction is typical of trolls. More on this paragraph below. Whether you think I deserved to get jumped on or not, I got many messages in short order attacking me. I guess I did hit a nerve. No one attacked you. People are at most criticising your ideas the same way you are criticising Linux I put Linux in quotation marks here because you are not and cannot criticise Linux, which is the kernel. You at most would be able to criticise some Linux distribuiton. But you NEVER told you which distribution where you trying to install. It could even be Android or some router embedded OS which also runs Linux. My experience has been: I make (or buy) CDs. Which distribuiton? I boot them. I begin the installation. Which hardware? I'm asked a hundred times whether I want to install this program or that program. The certainly it is not Debian. There is not a hundred questions in the installer. For software installation, there is only one question (tasksel). But I'm not at all prepared to choose because I don't know anything about Linux or the programs, so I choose to install them all. When you install Windows or Office you choose to install all options or keep the default ones? If you don't know yet about Linux, why don't you choose to keep the default options? Then when I try to boot my new Linux installation, I get an error message that such--such program is missing and boot is terminating with a kernel panic or a failure code. This has happened many times. When I asked about this in Linux forums, I got answers that only a Linux guru would understand. If you asked at a Linux forum, you should have received very technical answers. For user questions, you must ask at a distribution forum. Like this one. So, what is your question? Do you really have one or are you just trolling? Let me give you an example of the kind of insensitivity (or myopic stupidity) that seems to be the hallmark of the Linux community. In the Debian live page, dd is offered as the way to copy the ISO file to a USB stick. But the dd program offered only runs in Linux! What good is that to someone who is running Windows at the time? It's like Linux is in it's own world. So here we have it. You are trying to run a Linux distribution from USB stick. Somehing very exotic, not for beginers. Now I dare you to prove that it is easier (or even possible) to do this with Windows. If you are complaing that doing in Linux something that is impossible in Windows and alleges that it is easier to do this thing in Windows is easier than in Linux, you are... T R O L L I N G. I thought I was at a forum in which people would like to advocate for Linux and therefore would do what's needed to assure successful conversion from Windows to Linux, You are in the wrong forum. Convertions are religion business. but instead I experience the same elitism and condescension I'd experienced at other Linux forums. So, you don't want condescension, but if someone criticise you, then you are being jumped on. Can you see how ridiculous your argumentation became? If you can't see that, then you are part of the problem. I give up. I apparently will never run Linux because I'm too stupid. No one here cares about this. Here we are in the answer-to-objective-questions-and-solve-real-problems business. So, what is your question? What is your problem?

Re: Snapshot Program

Something that I can restore through CLI I am always playing around with my distro and sometimes things do not run well, and I feed the need to restore a yesterday's image. Is it possible? Regards, Hélder Pinheiro Hi, I'm using Clonezilla for that. www.clonezilla.org/ Just capture a snapshot of system partition and you can restore it. It's a live distro. [LVM blurb] As a permanent solution, consider installing the system in an LVM (Debian supports this mode of installation), which supports an operation called snapshot. Leave some space in the volume group so that you can take a read/write snapshot of the logical volumes (LVM equivalent to partitions) before the modification of the system. Snapshots are copy on write, which means that they are created very fast and you need spare space in the volume group only to accommodate the modifications of the filesystem while the system is running. The snapshots are created online, while the system live and running, and there is a graphical interface system-config-lvm (which I don't use) alongside the command line tools. The logical volumes can be resized without the constraints of the partition table. After you made the modifications, if you want to restore the previous state, just delete the modified logical volumes and rename the snapshots so they take place of the original logical volumes. There is a lot of hope in the upcoming btrfs filesystem that will implement all these features within the filesystem, but LVM is already a mature and reliable tool.

João Luis I thought when you wanted to incorporate the changes(data stored in snapshot) into the original volume you had to merge them(lvconvert --merge). Is this incorrect? No, this is the correct solutions and works also when the snapshot is read-only. Let make things a bit more clear. You take the snapshot and make changes in the original logical volumes. If you want to revert the changes, you call lvconvert --merge, which will revert the logical volume to its original state. The name merge is somewhat misleading, I think. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Re: a very carefully asked question?
Hi folks, I have been considering all day how I will ask this. it is very very important that I get the answer I seek, and with so many variations, things can shift off the mark if not careful. going to keep it simple only adding extra detail if necessary. If one already has an install of debian, in this case squeeze that did not involve including network access at the time, how does one add the networking aspect later? I will have working dsl I trust this weekend. I want the individual helping me connect my main computer to also inform my Debian machine that a network connection exists, letting debian establish the best drivers etc., for the network. How specifically is this done? Chances are that your network card was detected and the correct kernel module is already being loaded. If this is the case and you never touched any network configuration file, and also you dsl provider does not use pppoe but instead plain ethernet with dhcp, then networking will just work when you connect the network cable. If it does not work, please write again to this list including the output of the comands cat /etc/network/interfaces dpkg --status network-manager | grep Status lspci -v dmesg | grep eth0 /sbin/ifconfig and whether your provider uses pppoe or plain ethernet with dhcp.

Re: debian wheezy amd64 freeze
did you unload the old kernel driver? at least you need a `modprobe nvidia` after dkms install and then restart the graphical login manager (kdm, gdm...) -r I did it (the driver was loaded. ) but I still got the error screen not fount. I've tryed to manually edit the xorg.conf but nothing change. Is the nouveau driver blacklisted? If you are using the proprietary nvidia driver, you should have a file in /etc/modprobe.d/, say /etc/modprobe.d/nvidia-graphics-drivers.conf, containing blacklist nouveau blacklist lbm-nouveau blacklist nvidia-173 blacklist nvidia-96 alias nvidia nvidia-current On the other hand, if the nouveau driver is being loaded in the initramfs, it must be disabled in the kernel command line. Try putting nouveau.modeset=0 in the kernel command line in the grub boot menu or set the variable GRUB_CMDLINE_LINUX=nouveau.modeset=0 in /etc/default/grub and run update-grub.

Re: Can't execute binary?
Hi, I've just installed wheezy/KDE on a spare machine, to see what we're getting. All seems OK, apart from one mystery: I installed a copy of Firefox-18.0.2 in /usr/local, with a symlink pointing to it, as I have done in Squeeze and earlier for years. Typing /usr/local/firefox/firefox always used to start it with no problem. However, on the wheezy box, I'm getting: --- tony@tony-dlt:~$ /usr/local/firefox/firefox bash: /usr/local/firefox/firefox: cannot execute binary file --- Well, WTF, as they say. Does anyone know of a change that causes this? Is the copy of firefox the same architetcture of the spare machine?

Re: OT: What is the meaning of /proc/$PID/fd/* files?
I am trying to figure out the meaning of: /proc/$PID/fd/* files. These are links that point to the open files of the process whose pid is $PID. Fd stands for file descriptors, which is an integer that identifies any program input or output in UNIX-like systems. and then if I tried something like this: echo foo /proc/$PID/fd/0 [..] What actually happened was: - foo string appeared on the appropriate terminal - the ./main process remained blocked in the read system call. You program has the terminal opened as file descriptor 0 which corresponds to standard input (1 and 2 are standard output and standard error). If you list /proc/$PID/fd you will see something like this: $ ls -l /proc/$PID/fd/0 lrwx-- 1 root root 64 Fev 19 11:55 0 - /dev/pts/7 meaning that your program has opened pseudo terminal 7 (probably an xterm) as its standar input. So when you write to /proc/$PID/fd/0, you are really writing to /dev/pts/7, that's why you see things appearing to the terminal. You cannot write to the standard input the way you thought because it is already linked to the terminal. Only the terminal can write to your program's standar input. Is there somewhere a concise and correct description that explains this? I learned a lot about those subjects in the book Linux A-Z by Phil Cornes, but I think that /proc in Linux is becoming very specific. You have to learn a lot in man pages, kernel documentations, google, etc. Best wishes, João Luis. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
