  • Automatically cycle numerous or large files to the trash

    - by minameismud
    I've been tasked with fixing a vendor's program that, under certain conditions, dumps gigs of junk files into a log directory. It ends up filling users' machines. My task is to figure out how to make it stop without any source code or additional running processes, and without making the program kasplode. In other words, I'm looking to use a feature of the file system to control the growth. One idea I had was to make a hard link from that folder to NUL, as you might with /dev/null in the linux world. However, my attempts to use the mklink program to create a junction result in a message that says Local volumes are required to complete the operation. Any ideas on how to complete the junction, or other ideas to solve the problem?

  • Sun Java crashing, mostly with jboss

    - by Joel
    I'm on Ubuntu 10.10. I keep having problems with Sun Java crashing on me. I mostly have it crashing on my Jboss server, but I've had it crash MANY MANY times running ANT tasks or the IntelliJ IDE. Here's what it prints: # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f67e665d440, pid=21260, tid=140082772170512 # # JRE version: 6.0_22-b04 # Java VM: Java HotSpot(TM) 64-Bit Server VM (17.1-b03 mixed mode linux-amd64 ) # Problematic frame: # V [libjvm.so+0x2f2440] # # An error report file with more information is saved as: # /home/blah/blah/blah/hs_err_pid21260.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # Aborted A co-worker of mine who has the same version of Ubuntu has had the same problem, but has only happened to him once. (I get this probably 2 or 3 times a day, if not more). I have another machine running Ubuntu 10.04 with Sun Java and I have yet to see this problem. 1.0.6_20 is the java version on the 10.04 machine. My machine is running 1.6.0_22. Has anyone else had this problem? Anyone know how to keep it from happening? Also: I have tried reinstalling it and I can't use OpenJDK.

  • Internet unusably slow with Realtek Semiconductor Co., Ltd. RTL8111/8168B card

    - by user42424
    So I have recently installed Ubuntu 11.10 for a dual boot with wind 7. After the install I had like 300 updates, so I installed them. At first I could use the internet, although it was extremely slow. However now I cannot, sometimes it will load and others it will simply time out. When I try to download something it will either take forever or will not at all. This is a wired system. On Windows side my speeds are fine. Any help would be greatly appreciated. Also like I said I am new to Linux/Ubuntu so please be nice. One last thing, I also installed 11.10 for same dual boot on my laptop, and wireless speed is the same as on Windows? Only the wired desktop gives me the problem? Hear is some hardware info.. Hope it helps.

  • Hue shift on youtube.com (but not when embedded!)

    - by Mala
    This is easily the oddest problem I've yet had. When I'm on youtube, and I look at a video, the hue is all wrong. Pure red becomes pure blue, and all the other colors shift accordingly. Faces in particular are shades of blue so I call this "avatar mode". Avatar mode happens on any video I view while on youtube.com. BUT, if I view the same video when embedded, colors are fine! EDIT: OS: Gentoo Linux, happens in all browsers

  • Is it possible to code on two different computers simultaneously?

    - by Muhammad
    I want to work with another programmer and I want the source code to be live in real-time on both of our screens. Is this possible on the Mac OS x or Linux? We're going to be using OS X but occasionally we might need to add an Ubuntu computer too. Is there a way I can do this using ssh, any shell based program, or even a good GUI? I thought Coda might be capable of this but it's not really working. Anyone ever do this? I'm not look for a git/svn/or any other version control system. This is more of a live coding session. :)

  • "Can't open display" even after access with xhost

    - by Yann
    I'm trying to run a graphical program remotely, without using ssh. I've set the display variable on the server (let's say server.com, Linux, not ubuntu, and no su rights) to point to my workstation (workstation.com, ubuntu 10.04) setenv DISPLAY workstation.com:0 Then on my workstation I've tried both xhost +server.com and xhost + Then I ssh into the server (to test things): ssh [email protected] and try to run xclock, and get the following error: Error: Can't open display: workstation.com:0 I've looked at /etc/ssh/ssh_config on the workstation and I should be forwarding correctly: X11Forwarding yes. How do I go about troubleshooting this? What logs on the workstation document these failed attempts? To explain why I'm doing this: I want to run a batch job on a server to debug an MPI-based parallel program. I want to run xterm as the batch job executable, per the instructions provided by the system admins. This setup use to work. I reinstalled things on my workstation and since then I frequently get one-time message along the lines The authenticity of host 'hostname (XXX.XXX.XXX.XX)' can't be established. My attempt to fix the above was to move my ~/.ssh/known_hosts file to a back up on both server and host, and then to ssh from each to the other with the flag -o StrictHostKeyChecking=no. I no longer get that message, but I was wondering does this play a part in why X11 forwarding is not working?

  • What's hot in Oracle Premier Support News for Solaris, Storage and Systems - How to Patch!

    - by user12244613
    Struggling with locating patches for Sun products? Can't find your Oracle System Drivers? This question has been raised many times by customers and was the source of a short video in the Oracle System Support Newsletter in February 2012. The transition between SunSolve and My Oracle Support is to change how you think about the type of patch your looking for. For example, in SunSolve you might have typed e1000g if looking for an Enternet Driver.. but entering e1000g will not find anything in My Oracle Support - Patches and Update Menu. As you need to use the Product (Advanced) search which is driven of the Product Name, therefore you need to type "Ethernet" and select the ethernet product you are looking for to locate the patches for this product. Just to recap that video: If you are looking for the e1000g Ethernet Driver - You need to use Advance Search and search for Enternet 1. Log into My Oracle Support - Select Patches and Updates - Select Product or Family (Advanced Search). 2. In the product line enter: Ethernet and select the product name from the menu. 3. Check remove supersede patches - that ensure you only get relevant current patches in the results. 4. Select Search and the results are displayed. Now you have more options to include the platform (Solaris,Linux etc.) if want to further narrow the search. Need more information? Log into My Oracle Support and what a short 90sec video I put together. View the 7 minute Video using Firefox/chrome – It shows searching for individual patches, Solaris, Firmware etc. If you are not receiving the Oracle System Support Newsletter: Option (a) Within My Oracle Support, make document id: 1363390.1 a favourite and revisit it on the 2nd of each month for the latest content. Option (b) By default the Newsletter  is sent to all customers who have logged a Service Request on an Oracle Systems Hardware Product during the last 12months, unless you have opted out to receiving Oracle Communications on your profile on http://oracle.com

  • Can't write to disk

    - by nofacts
    I have seen questions similar to this, but the answers are either beyond me or the situation doesn't quite match mine. Would appreciate some direction. I recently installed Ubuntu 12.04 LTS. The OS is on a disk formatted as ext4. I added another disk to the system and formatted it as W95 FAT 32 (LBA) (0x0c). I did this because I am moving from Windows to Linux, will be needing to go back and forth with data for a while, and might need to move the disk to a Windows machine. There may have been a better format to use, but if so I didn't know any better. I was able to transfer data from an external drive to this FAT32 drive with no problem. Now, though, when I try to create a new folder or write a file to the disk I get a message that the disk is read-only. If I go to the properties, permissions for the disk, for Folder Access it says 'create and delete files'. If I try to change File Access underneath to 'read and write', either nothing happens or I get a message it can't be done. Thank you for any help.

  • How to move ubuntu 12.04 on another drive

    - by Maksim
    How I can move my ubuntu on another drive? I know about clonezilla but problem is that destination drive is smaller the source one. Gparted can't copy-paste partition if destination not the end last partition. I tried dpkg --selected-packages and apt-clone. First one just not install all my packages and removed existed that now I have no full unity and not my all packages. Second one just fail on configuration package. But before I did that way I copy-paste my /etc to new system.

  • Good free software to track and graph memory and CPU usage on Windows?

    - by TheLQ
    There are many questions on Linux memory tracking, but I haven't seen any for Windows. In my case however its a Windows XP Pro box I need to track the memory and CPU usage of. The reason I need it is due to a server program I'm trying that is eating all my processor and some of my memory which is freezing my RDP session and System Explorer and even makes it difficult to login physically. As this is a very constrained server I'm working off of (768 MB RAM with Pentium 4 which disappears with this program), I need a program that doesn't run/require a webserver. I can give it a MySQL database if necessary however. Is there any suggestions for such a program?

  • Disable/configure Back and Forward through mouse wheel in Internet Explorer

    - by Subtwo
    I have a problem with Internet Explorer (version 7 on Windows XP). Sometimes (not always) when you use the mouse wheel to scroll a page up/down it instead chooses to go back or forth in the web browsing history. This behavior is the same as when you hold the shift-key simultaneously using the wheel. My guess is that Internet Explorer somehow gets misled by something and thinks that I'm actually pressing shift. This is in turn maybe an artifact of the fact that this particular session is a remote-desktop session originating from Linux (Ubuntu). Needless to say the problem can be quite irritating and the alternative of completely turning off the wheel functionality doesn't seem like an option as other applications would suffer greatly from this. Anyway back to my question(s): Is it possible to map the shift+wheel to a simple wheel event for Internet Explorer? Is it possible to disable the shift+wheel event for Internet Explorer? Any suggestions are greatly appreciated.

  • Laptop keyboard and touchpad disabled on startup

    - by JAM
    I use Ubuntu 14.04 LTS on my Toshiba Satellite L775D laptop. 14.04 is the only operating system installed. I am new to Linux and only barely scratching the surface of doing things in terminal. When I boot my laptop keyboard and touchpad are disabled (99.99% of the time) if I do nothing. The only direct effect I can have is to keep pressing the "numlock" key during boot when I notice the "numlock" light goes off. If I do this then I have a 95% chance of the keyboard and touchpad working when I am in the operating system. I am able to use my wireless mouse regardless. I have not seen any messages during boot. Previously I have tried playing with input method settings and utilities as well as language support settings. This same problem exists with the 12.... and 13... versions of ubuntu. With everything I have tried (from looking at other posts/suggestions) it seems I can have only a temporary effect. Please help me find a permanent solution to this problem. thank you.

  • postgresql creating and managing users

    - by MalphasWats
    I've tried a few times to get postgresql running on a couple of different linux boxes, but I've always ended up binning it and going back to MySQL because I can't get my head around how to create and manage users. This time around, I've actually gotten as far as being able to log in with my own account, but I created the account with the createuser command and it has a different password to my actual user account. What I'd like to be able to do is log in as me to create databases, users and assign database permissions, but then have an account that is separate and doesn't have an account on the server to use with my web app. Does anyone have a good step-by-step guide for complete morons that goes through creating users and assigning access to various databases in postgresql?

  • Grandma's Computer - Can a user that belongs only to the "Users" group in Windows XP install malware, virus or IE addons?

    - by DanC
    I am trying to figure out if having a user in the "Users" group will be enough to prevent her from install unwanted software. The things that I don't want the user to be able to install are: virus malware bandoo stuff Internet Explorer Addons To put you in context, I am thinking of my grandma's computer, I want her to be able to read all her email stuff and attachments, but without the hassle of needing to reinstall the whole computer every few months. The computer will run Windows XP, with some free antivirus. It will not be part of any domain. It is just a home computer. Linux, I have tried making her use it, but she was already accustomed to Windows and was not really an option to have her re-learn where was the shutdown button. So, are these considerations enough to prevent her installing unwanted software? What other options come to you mind? Thanks

  • Recommend AntiVirus for Plesk 8.6.0 + CentOS 5

    - by cappuccino
    I am using a virtual server on Media Temple running CentOS 5 and Pleak 8.6.0, I have done all their security recommendations and more some, blocking everything except http and mail, string passwords and running Rootkit Hunter daily. But i'm thinking I should run a antivirus of some sort? I'm still new to Linux CentOS security so please forgive :)... Can you recommend a good antivirus/antispyware software for CentOS 5 and Plesk 8.6.0? I've been searching for some plesk modules and have come across a few like Kaspersky, not sure which one to use... Any tips on security would be good too.

  • How to completely remove MySQL from Windows?

    - by Nathan Long
    (I realize there are similarly-titled questions, but this one is really 'how do I reset the password', and this one doesn't specify an OS and has only gotten Linux-oriented answers.) On Windows XP, I just uninstalled MySQL and deleted the folder that it was installed in. I then rebooted and reinstalled MySQL. When it comes back up, it still has the databases it had before the uninstall. Where did it keep that database info? How do I completely remove MySQL and start over, as if I'd never installed it?

  • GVim Stop at end of line with arrows

    - by viking
    When using the arrow keys in Vim on Linux, they act the same way as h and l , stopping when the end of a line is reached. GVim on Windows doesn't do this, instead allowing the arrow keys continue past the end (or beginning) of a line and on to the next line. Is there any way to change the arrow key behaviour and cause them to stop at the end of a line like the character navigation keys? NOTE: I am not looking for a way to get to the beginning or end of a line, I realize that 0 and $ do this.

  • Software development company business plan

    - by Navi
    I apologize in advance if this is the wrong forum for this question, so please forward me to the right place. I have about 10 years professional experience as software developer. Mostly on the Java platform doing server side programs. I have picked up a bit of Linux skills on the way as well. I know HTML and Javascript, so I can make a website that would not be too ugly, but I am not going to win any prizes with it. In fact I think I am pretty terrible in the user interface department. My initial plan is to do Android development. I read a few Android books and tried making a few apps. Since it is Java based I think I got the technical side down. Lately I have been thinking about iphone and Mac development, because of the relevant app store/development programs. The trouble is I don't know Objective C. As a side question, how long would it take me to become proficient in Objective C? Considering that I am working on my own and could hire somebody to help me for a short time for low wages if necessary what are my options? What are the pro and cons of the development programs app stores of Android and Apple? Which development/app stores are out there beside the ones I mentioned? Do you think it is necessary to find funds to get me started or should I just use my savings? If you have positive/negative experiences in a similar situations can you please share them? Thanks for your help.

  • Is it possible to use multi keyboards with multi keyboard layouts simultaneously?

    - by mono
    Considering to switch to dvorak layout, but this terminal is used by multi users as the same user account. It is unacceptable to ask all people to switch layout, plus it is hard to use dvorak layout with a keyboard qwerty-ly labeled. But there are spare (USB,qwerty) keyboards, so if I plug another keyboard in and be able to use multi layouts on different psyical keyboard simultaneously (I will rearrange letters on keys), the problem get solved. solution for either windows or linux is fine. anyway thanks all.

  • 1tera flop cluster?

    I want to buy a $40000 1 tera flop cluster to keep it in a room. What are the standard configurations? Cluster is supposed to do molecular dynamics simulations on biological systems. I'm proposed a 4 pc with 8 cores each by the selling company I'm deadling with. It looks like I also need infiniband. Does some one has an experience -- what phisical memory should I buy etc? I know things change very quickly... Still there might be a point or two to state. Edit: OS is supposed to be linux, application is gromacs.

  • How do I set the umask for files and directories created from the GUI in MacOS X Lion (10.7)?

    - by Avry
    I've set my umask in my .bashrc file to 007. Any files created on the command line after loading my bashrc file respects this setting. I want to be able to set the umask to 007 for any files created using non-command line apps. This document talks about setting the umask via launchd. And it kind of works. If I follow these directions I can change the default permissions on a GUI created file from rw-r--r-- to rw-rw---- but the directories still are not group writeable (i.e. I want them to be rwxrwx--- but they are rwxr-x--- instead) The analog on Linux would be /etc/login.defs as the place to set the umask. What do I change in order for the umask to be set properly (i.e. the way I want it)?

  • With the outcome of the Oracle vs Google trial, does that mean Mono is now safe from Microsoft [closed]

    - by Evan Plaice
    According to the an article on ArsTechnica the judge of the case ruled that APIs are not patent-able. He referred to the structure of modules/methods/classes/functions as being like libraries/books/chapters. To patent an API would be putting a patent on thought itself. It's the internal implementations that really matter. With that in mind, Mono (C# clone for Linux/Mac) has always been viewed tentatively because, even though C# and the CLI are ECMA standards, Microsoft holds a patent on the technology. Microsoft holds a covenant not to sue open source developers based on their patents but has maintained the ability to pull the plug on the Mono development team if they felt the project was a threat. With the recent ruling, is Mono finally out of the woods. A firm precedent has been established that patents can't be applied to APIs. From what I understand, none of the Mono implementation is copied verbatim, only the API structure and functionality. It's a topic I have been personally interested in for years now as I have spent a lot of time developing cross-platform C# libraries in MonoDevelop. I acknowledge that this is a controversial topic, if you have opinions that's what commenting is for. Try to keep the answers factual and based on established sources.

  • I receive the error 'grub-install /dev/sda failed' while attempting to install Ubuntu as the computer's only OS.

    - by Liath
    I am attempting to install Ubuntu on a box which was previously running Windows 7. I have also experienced the dreaded "Unable to install GRUB" error. I am not attempting to dual boot. I have previously run a Windows boot disk and removed all existing partitions. If I run the Ubuntu 12.04 install CD and click install after the config screens, I get the error Executing 'grub-install /dev/sda' failed. This is a fatal error. (It is the same error as this question: Unable to install GRUB) All the questions I've read while looking for a solution are related to dual boot. I'm not interested in dual boot, I'm after a clean out the box Ubuntu install. How can I achieve this? (For my sanity, please use very simple instructions when responding. I don't claim to have any talent either for linux or as a sysadmin) Additional details copied from comments dated: 2012-05-29 ~15:19Z After booting from the CD, clicking Try Ubuntu, and then sudo fdisk /dev/sda I get fdisk: unable to seek on /dev/sda: Invalid argument sudo fdisk /dev/sdb gives Device contains neither a valid DOS partiion table, nor Sun, SGI or OSF disklabel.

  • Protect Windows VPN from Unauthorized Users

    - by kobaltz
    I have a VPN connection that I use while away from home to remote into my home network. I would use a zero config solution like Hamachi, but need access from my mobile device. Therefore, I have my Windows Home Server acting as the VPN server and will accept incoming connections. Both the username and password are strong. However, I'm worried about brute force attacks against my network. Is there something else that I should do to protect my network from having unauthorized access attempts to my network? I'm familiar with Linux's FAIL2BAN, but wasn't sure if something similar existing for Windows.
