  • Is there an encrypted write-only file system for Linux?

    - by Grumbel
    I am searching for an encrypted file system for Linux that can be mounted in a write-only mode, by that I mean you should be able to write/append files, but not be able to read the files you have written. Access to the files should only be given when the filesystem is mounted via a password. The purpose of this is to write log files and such, without having the log files themselves be accessible. Does such a thing exist on Linux? Or if not, what would be the best alternative to create encrypted log files? My current workaround consists of simply piping the data through gpg --encrypt, which works, but is very cumbersome, as you can't get easy access to the file system as a whole, you have to pipe each file through gpg --decrypt manually.

  • Why doesn't openSUSE Linux upgrade itself through its software repositories?

    - by Dougal
    openSUSE - fast becoming my favourite Linux distro on the client - doesn't seem to upgrade itself through its own configured software repositories. Do we know why this is the case? Is it a money-making thing where they can then sell upgrade CDs / DVDs? I mean, pretty much every other Linux upgrades itself through the normal software repositories. For example, Ubuntu can upgrade itself from 10.4 to 10.10 just through the normal software package upgrade procedure. Why must it be a huge procedure to upgrade openSUSE? Any knowledge or ideas appreciated. Thank you.

  • Amazon Linux AMI release 2010.11.1 corresponds to which RHEL version (4/5/6)?

    - by Jayesh
    I am using the default Amazon Linux AMI in an EC2 instance - Amazon Linux AMI release 2010.11.1. I can see that it's a Redhat based system, but after trying many tools (/etc/issues, uname -a, lsb_release), I cannot tell which version of RHEL or CentOS is it based on. I need to get some packages that are not available in Amazon's package repos. I have list of custom yum repos that I can use, but since I don't know which RHEL version is the Amazon AMI based on, I cannot choose from different versions of repos. How can I find whether it's running RHEL 4/5/6 (or their CentOS counterparts)?

  • Why using swap file over a SMB/NFS mounted filesystem is not possible in Linux?

    - by Avio
    I'd like to use another machine's unused RAM as swapspace for my primary Linux installation. I was just curious about performance of network ramdisks compared to local (slow) mechanical hard disks. The swapfile is on a tmpfs mountpoint and is shared through samba. However, every time I try to issue: swapon /mnt/ramswap/swapfile I get: swapon: /mnt/ramswap/swapfile: swapon failed: Invalid argument and in dmesg I read: [ 9569.806483] swapon: swapfile has holes I've tried to allocate the swapfile with dd if=/dev/zero of=swapfile bs=1024 (but also =4096 and =1048576) and with truncate -s 2G (both followed by mkswap swapfile) but the result is always the same. In this post (dated back to 2002) someone says that using a swapfile over NFS/SMB is not possible in Linux. Is this statement still valid? And if yes, what is the reason of this choice and is there any workaround to have this working?

  • Is it safe to use up all memory on linux server, not leaving anything for the cache?

    - by Temnovit
    I have a CentOS server fully dedicated to MySQL 5.5 (with innodb tables mostly). Server has 32 GB RAM, SSD disks, and avarage memory usage looks like this: So about 25GB is in use and about 6.5GB is cached. I am experiencing performance problems with WRITE queries, so I was thinking, is this the optimal cache size? I might increase innodb buffer size, so that linux cache would become smaller, or decrease it, so it would be bigger. What is the optimal used/cached memory balance for busy MySQL server on linux?

  • How can I get OS/X-like switch windows of same program bound to hotkey with linux GUIs?

    - by dbenhur
    On OS/X, Command-~ switches between windows associated with the program with current focus. This is very handy when toggling through a set of browser windows or editor windows, for example. A couple years ago I noticed someone using similar functionality on a Gnome linux laptop and they showed me how to set it up, but I forgot the details (so I know it's possible). I frequently switch between MacBook and a variety of linux systems running Gnome, Unity, and occasionally KDE. My Google-fu failed so I turn to stack exchange: How do I bind Alt-~ or similar key to give me functionality to switch between windows of program with current focus?

  • ATI Radeon Drivers works with which linux distribution and version? [closed]

    - by amit.codename13
    I have ATI Mobility Radeon HD 5850 graphics card. Almost every new linux distribution seems to have an issue with it, when i install the drivers. Working without utilizing the graphics card leaves me so unproductive. So i made a plan to use older versions of linux, any distribution suitable as a desktop distribution. The problems that i am facing are, 1) After installing drivers the system boots and hangs, 2) There are unusual lines over the screen 3) After upgrade system doesn't start properly(hangs the usual old way) The kind of answers i am looking for is, distribution X(the newer the version the better) doesn't have the above problem after installing drivers for ATI Mobility Radeon HD 5850 graphics card. UPDATE: The new drivers released by AMD seems to fix all the issues, although they are still beta

  • is there a cheatsheet for linux commands to save your system?

    - by Asaf
    I've recently lost my window options, had to somehow manipulate my way to Xchat and ask some people how do I get it back (it was metacity --replace, and after I decided to stop the command and run it in background the X was completely useless so I had to do killall -u user). And that was after the internet connection stopped working for some reason (might've been the ISP) ..The thing is, after using linux a long time, I still get the feeling that on dire situations, I don't know the good tricks (stuff like metacity --replace) I feel like a really need like a "rescue" cheatsheet for things like "how to save the X no matter what without pressing reset" and "how to reset the system to "normal state"" "how to connect to the internet through the command line" "how to monitor what the X is doing" (using ubuntu linux 10.04 btw)

  • Creating a command that compress a file and save it on a usb, but cannot detect the usb in linux.

    - by Lance
    First of all I can't detect the USB on linux using the command line. I check the directory dev and still cannot find the usb. used the df command to check the usb. I plug and typed df and then unplug and typed df again and nothing changed. We are using a server(telnet) to use the command line of linux on a windows 7 OS. The second problem I have is how can I execute the bash script that I have made. It seems that I cant put my .sh file in /usr/bin/ I would like to make my command executable in all directories like a normal command. Sorry, im still newbie at this things. This is what I get on staying on Windows too much. Sorry for my english. Thank you in advance.

  • (How) does deleting open files on Linux and a FAT file system work?

    - by lxgr
    It's clear to me how deleting open files works on filesystems that use inodes - unlink() just decreases the link count to zero, and when the last file handle to the file is closed, the inode will be removed. But how does it work when using a file system that doesn't use inodes, like FAT32, with Linux? Some experiments suggest that deleting open files is still possible (unlike on Windows, where the unlink call wouldn't succeed), but what happens when the file system is uncleanly unmounted? How does Linux mark the files as unlinked, when the file system itself doesn't support such an operation? Is the directory entry just deleted, but retained in memory (that would guarantee deletion after unmounting in any case, but would leave the file system in an inconsistent state), or will the deletion only be marked in memory, and written at the time the last file handle is closed, avoiding possible corruption, but restoring the deleted files after an unclean unmount?

  • How does Linux's unlink on a NTFS filesystem differs from Window's own implementation?

    - by DavideRossi
    I have an external USB disk with an NTFS filesystem on it. If I remove a file from Windows and I run one of the several "undelete" utilities (say, TestDisk) I can easily recover the file (because "it's still there but it's marked as deleted"). If I remove the file from Linux (I'm using Ubuntu) no utility can recover the file (unless I use a deep-search signature-based one). Why? It looks like Linux does not just "mark it as deleted" but it wipes away some on-disk structure, is this the case?

  • Building a J2EE dev/test setup on a single PC

    - by John
    It's been a while since I did Java work, and even then I was never responsible for starting a large project from the very start... there were test/staging/production systems already running, etc, etc. Now I am looking to start a J2EE project from scratch on my trusty workstation, which has never been used for Java development and runs Windows 7 64bit. First of all, I'll be getting Eclipse. As far as writing the code goes I'm pretty happy. And running it through Eclipse is OK, but what I'd really want is to have a VM running MySQL and TomCat on which I can properly deploy my project and run/debug it 'remotely' from my dev PC. And I guess this should be done using Ant instead of letting Eclipse build the WAR for me, so that I don't end up with a dependence on Eclipse. I'm certain Eclipse can do this, so you hit a button and it runs Ant scripts, deploys and debugs for instance, but very hazy on it. Are there any good guides on this? I don't want to be taught Java, or even Ant, but rather the 'glue' parts like getting my test VM up and running under Windows, getting a build/test/deploy/run pipeline running through Eclipse, etc. One point, I only plan to use Windows... hosting a Windows VM on my Windwos desktop. And while I can use command-line tools like ant/svn, I'm much more a GUI person who loves IDE integration... I'd rather this didn't end up an argument about Linux or Vi, etc! I am looking for free, but am a MAPS subscriber, and run Win7 Ultimate in case that makes a difference as far as free VM solutions.

  • Is there a Linux mail server with an outgoing pickup directory?

    - by Paul D'Ambra
    On my Exchange server I can drop appropriately formatted text files in the "pickup" directory and Exchange will process them. I'd like to split this bulk mailing functionality onto another box to protect our business mail IP from the bumpy ride that our monthly newsletter gives us. I should note at this point that the mailing is opt-in with an opt out link included and only goes to people who pay to be a member of our organisation The ideal solution for me would be to add a linux box to use just for this purpose so we're not paying for Exchange licenses. So is there a linux equivalent of the Exchange pickup directory?

  • Why is it possible to change the password of an admin user on linux?

    - by enum
    A few days ago, a friend of mine, wanted to show me that he can use my linux even if I don't tell him my password. He entered in GRUB, selected the recovery mode option. My first problem is that he already had access to my files (read only). He tried to do passwd but failed. Then he did some kind of remount (I guess that gave him write rights) and after that he was able to change my password. Why is this possible? I personally see it a security issue. Where I work there are several people that use linux and neither of them have a BIOS password set or some other kind of security wall.

  • Boot custom linux up by pressing Lenovo OKR button?

    - by Semmu
    I have a Lenovo Y510p laptop and I'm a Linux user, use Windows only for gaming. The device had no OS when I bought it and I also installed an SSD besides the 1TB hard drive. I would like to "hack" the One-Key-Recovery button, because I have no interest in its default behaviour (I don't need Windows recovery), but if I could boot up a hidden, fail-safe Linux with it, that would be great. How could I achieve it? I tried to search what the button does, but I only found some installers for Windows that could magically create a partition for the recovery. I would like to override this behaviour completely to boot up something else.

  • How to get a windows domain server to recognize a linux machine by its name?

    - by CaCl
    In my company I ran into an issue where we have a linux machine that serves up a Subversion repository. Its hooked up via LDAP to the Active Directory. We got an account setup for an application and they set the Limited Workstations up so it didn't have full access to the network. The problem is that even though the hostname for our machine resolves correctly for me, the credentials for the application account seem to come back as not being allowed based on the name (the error was related to authorized workstations). I don't have access to any of the domain servers but it might be helpful to come at the management or high-level techs with some ideas, they don't seem to have a solution besides allowing all workstations for the user. Does anyone have any idea on how to get my linux machine to properly identify itself with the Domain machine by name?

  • Best virtualization solution for running Linux under Mac OS X?

    - by grumbles
    I'd like to run a virtualized Ubuntu instance under Mac OS X (10.6). I've used VirtualBox in the past, but am looking for something that will be faster, and don't mind paying for either Parallels Desktop or VMWare Fusion. Does anyone have experience running Linux guests under either or both programs? I'm primarily interested in doing software development on the Linux guest installation, but I'm also very concerned with the performance and responsiveness the guest OS. I have a mid-2010 15" MacBook Pro (2.66 GHz i5, 8 GB of RAM, NVIDIDA GeForce GT 330M). Thanks!

  • Performance impact of running Linux in a virtual machine in Windows?

    - by vovick
    Hello, I'd like to know what performance impact I could expect running Linux in a virtual machine in Windows. The job I need Linux for is heavy and almost non-stop code compilation with GCC. Dual-boot doesn't look like a very attractive solution, so I'm counting on low VM overhead right now (10-20% would be fine for me, but 50% or more will be unacceptable). Did anyone try to measure the performance difference, are there any comparison tables? What virtual machine with the lowest overhead possible will you suggest? My host OS is Win7 and I've got a modern Core i7 with VT-x present. Thanks!
