  • Why do I get "permission denied" errors with Python easy_install?

    - by ATMathew
    I'm an Ubuntu newbie and have been trying to install python's easy_install so that I don't have to deal with source files when install Python libraries. I"ve ran the following, and it seems to install the correct applications: sudo apt-get install python-setuptools However, when i run easy_install sqlalchemy or easy_install pysqlite3, it doesn't work. I get the following error message: install_dir /usr/local/lib/python2.6/dist-packages/ error: can't create or remove files in install directory The following error occurred while trying to add or remove files in the installation directory: [Errno 13] Permission denied: '/usr/local/lib/python2.6/dist-packages/test-easy-install-1674.pth' The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was: /usr/local/lib/python2.6/dist-packages/ Perhaps your account does not have write access to this directory? If the installation directory is a system-owned directory, you may need to sign in as the administrator or "root" account. If you do not have administrative access to this machine, you may wish to choose a different installation directory, preferably one that is listed in your PYTHONPATH environment variable. For information on other options, you may wish to consult the documentation at: http://packages.python.org/distribute/easy_install.html Please make the appropriate changes for your system and try again.

  • Gnome3 shell video corruption with ATI Radeon HD 4850 on 11.10 Oneiric

    - by AndyAtTheWebists
    I have a problem similar to what's been mentioned in a few other questions, namely: Ati incompatible with Gnome-shell? Gnome Shell Glitched Top Bar Ubuntu 11.10 I have read a number of other posts here and on other forums and have tried a bunch of different solutions. The Problem The problem manifests itself only in Gnome3. I have tried KDE, Unity and KFCE and all are fine. The graphics corruption is visible only on gnome panels (see images below). Everything works fine with the free ATI drivers, but they just lack power. The problem occurs with the proprietary ones from AMD/ATI. I have installed version 11.11 and 12.1 as per the instructions on wiki.cchtml.com/index.php/Ubuntu_Oneiric_Installation_Guide. I have the same exact problem in both cases. I have tried this on clean installs of Ubuntu 11.10 Oneiric Ocelot (x64 and x86) and on Linux Mint 12 (x64) with the same results. Also, it looks like after some time of not using it, the PC just freezes. Maybe an overheat? Will look into it. Things I've Tried I have tried the following fixes: Different versions of drivers from ATI including the latest - this worked for some, not for me. Installing Oneiric specific package generated from driver, as well as the default install Removed the Unity Global menu Disabled file manager handling desktop Disabled Compiz "detect refresh rate" Sync to VBlank in Compiz on and off Please help! This is the first time in 10 years that I've finally had the chance to switch my primary desktop to Linux (stopped doing .NET dev work), and this is really getting me down. This is what the problem looks like: And:

  • How to install java-1.7.0-openjdk-devel on RHEL Server 6.3?

    - by andand
    I have need of installing a Java 7 development environment on a RHEL 6.3 (system details are below). Following the official OpenJDK directions I tried yum install java-1.7.0-openjdk-devel (as root). This yields the error message: No package java-1.7.0-openjdk-devel available. The Java6 JDK java-1.6.0-openjdk-devel and the Java7 JRE java-1.7.0-openjdk are both available, but the Java7 JDK does not appear. Is there a non-default repository from which I can install this? If so what is it? Distribution: Red Hat Enterprise Linux Server release 6.3 (Santiago) Kernel: 2.6.32-279.5.2.el6.x86_64

  • Playing sound on server using php

    - by Lorenz
    I want to play a sound file on my server using PHP. The PHP script is called by Apache and runs under the user 'nobody', which has by default no access to the speakers. So I created a new user soundoutput which is allowed do play sound and has read permissions for the sound files he should play. If I'm logged in as root, I can play a sound file using echo password | sudo -Su soundoutput mpg321 '/path/to/sound.mp3'. The problem is, that it doesn't work when I'm executing this command using PHP's system_exec. I guess that user nobody isn't allowed to run sudo, but what can I do that he is allowed to do that? Any help appreciated.

  • Iptables mark incoming packet - vpn routing

    - by Tom
    I have connected my home to my workplace for out of house backup reasons through openvpn. The connection is working nicely. At work I have 5 fixed IP addresses. Now I would like to assign one of these IP addresses to be forwarded to my home machine. I have confirmed packet arrival at my home machine with tcpdump. The problem is that my default route at home is NOT the tun0 (naturally), but eth0 to my own ISP. So I created a separate routing table to route my tun0 packets back to where they belong, but do not how to mark the incoming packet which arrive through tun0 with iptables, so I can drive them back. I do not want any port restrictions, but only what comes from tun0 should leave through tun0 thanks tom

  • mounts aren't case-sensitive

    - by Asi
    I mounted a few drives from Linux boxes in my network, but those mounts aren't case-sensitive. The mount command I used ( from the man mount.cifs, case-sensitive should be the default ): mount //10.0.1.10/remote_folder /local_folder -t cifs -o username=xxxx,password=xxxx but those mounts aren't sensitive. for example doing: ls -l /local_folder/testfile.txt ls -l /local_folder/TESTFILE.TXT give's the same result... instead of 'file not found' Couple of important points: All drives are running on Linux machines. My local machine is running Fedora 18 and it is case-sensitive for ANY folder/file expect the mounted drives. All drive/mounts are case-sensitive when when doing SSH. So if I SSH from my local machine to a remote machine, doing ls -l /local_folder/TESTFILE.TXT will say file not found as it should. So I believe the issue is in my local machine and not in the way I did the mount. but I'm not sure where to look next (I'm new to Linux)

  • SDL mouse wheel not picking up

    - by Chris
    Running Ubuntu 11.04, SDL 1.2 trying to pickup mouse wheel up/down movement with this (stripped down) code: int main( int argc, char **argv ) { SDL_MouseButtonEvent *mousebutton = NULL; while ( !done ) { if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_LEFT) yrot += 0.75f; else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_RIGHT) yrot -= 0.75f; else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_WHEELUP){ xrot += 0.75f; }else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_WHEELDOWN){ xrot -= 0.75f; } while ( SDL_PollEvent( &event ) ) { switch( event.type ) { case SDL_MOUSEBUTTONDOWN: mousebutton = &event.button; break; case SDL_MOUSEBUTTONUP: mousebutton = NULL; break; default: break; } } } return 0; } strange thing is, scrolling with the mouse button does nothing, but if I hold down a mouse button or two and then move the mouse it hits the SDL_BUTTON_WHEEL code occasionally. This honestly reeks of a pointer issue, which would make sense since I've been spoiled with C# for the past couple years, but I am just not seeing it. How do i correctly find mouse scroll events in SDL?

  • There's IP but can't reach gateway

    - by icky
    I have just installed ubuntu 12.04 on my new laptop, and brought it back to home, but I found the wireless network does not work. Strangely, it has the correct ip, but can't connect to the gateway. ifconfig gives ip 192.168.64.36, with broadcast 192.168.79.255 and mask 255.255.240.0, this are all correct, the gateway is at 192.168.64.1 cat /etc/resolv.conf nameserver 192.168.64.1 nameserver 127.0.0.1 which i think it's also right. but when I ping 192.168.64.1, all packages are lost.

  • ATI Radeon 5800 series dual monitor unity not 3D accelerated

    - by Victor S
    When I had a single monitor setup, without Xinerama, with my current setup of Ubuntu 11.10, ATI 5800 series card, Unity showed transparencies, shadows, etc. (although graphics was reported as 'Standard' in the control/settings panel). Having switched to a dual monitor setup, dell 24" UltraSharp and a smaller Acer monitor, Unity shows only as 2d, even though I'm not loggin in to that display manager. WebGL performance is very sluggish, I'm getting the impression that the processor is doing all the work and the card isn't even accessible even though the drivers are installed (from the ubuntu repository, I did not compile custom drivers). Any tips on how to enable full 3D accelerationn and video card support.

  • Auto log off windows machine after certain number of minutes

    - by Marty Heath
    I have three machines on my network, two are windows xp and one is windows 7. i would like to have all three machines log a user off if they are on for more than 60 minutes. And I would like this to be applied to the machine not on a per user basis, because I do not want this policy to apply to those users on any other machine. I have installed winexit.scr on one of the machines but the problem is that I cannot change the default value of 10 minutes for the screensaver because that is controlled through group policy, and I cannot seem to find where to change that through group policy on a per machine basis NOT on a per user basis. If I have left out any details I apologize please let me know anything that is needed

  • Make a socket as a user but make it readable and writable by another

    - by user1598585
    I have a software that is run under user A, this software creates a socket in /sockets and the socket should be readable and writable by user B. I have tried setting the directory to have ownership A:A or A:B but when user A creates the socket, it ends up with uid A and gid A. Using ACLs has not helped so far, the default mask is preventing the rights to be effective. rw permisions for B will always turn into jusr r. If what I make is not a socket it will work fine. How can I best accomplish this task? (It is for a web-server where the web-application makes the socket and the web-server software forwards requests to it)

  • Puppet yum repo - Pull down 2.7.x vs 3.0.x

    - by Mike Purcell
    So a few weeks ago I started on the path to using puppet to automate all the configs/services. At the time I was using the EPEL repo, which installed version 2.6.x. After some reading I was trying to gain access to the flatten method available via the puppet stdlib, and thought it was available by default in the newer 2.7.x version. So I added a puppet repo with the following settings: [puppetlabs] name=Puppet Labs Packages baseurl=http://yum.puppetlabs.com/el/$releasever/products/$basearch/ enabled=1 gpgcheck=1 gpgkey=http://yum.puppetlabs.com/RPM-GPG-KEY-puppetlabs The problem with this, is it installed v3.0.x instead of 2.7.x. And apparently 3.0.x is a major upgrade which was released only a few weeks ago. Obviously I would prefer to use the 2.7.x for the next few months while PuppetLabs fix any defects which will inevitably arise after a major version. So my question is, what setting can I add to the puppet repo config to pull down only the 2.7.x branch and not the 3.0.x branch?

  • Two Routers, Two Internet (1 Open, 1 PPTP) - Routing?

    - by SomeUser
    Hi there, I'm trying to setup two routers - one to route specific sites to a always-on PPTP VPN connection, the other for open internet access w/ firewall. First router is connected to Internet w/ built-in firewall. Second router is connected to a PPTP VPN connection. I was going to connect a wire between the routers and would like some insight on how to get both groups of systems (connected to each router) to talk between automatically. Even better would be to setup one gateway for certain sites and another for general Internet. The other option is to default all sites to the net and shoot others to the gateway or vice versa... Any insight so I can get a better grasp of this? Thanks!

  • Finding header files

    - by rwallace
    A C or C++ compiler looks for header files using a strict set of rules: relative to the directory of the including file (if "" was used), then along the specified and default include paths, fail if still not found. An ancillary tool such as a code analyzer (which I'm currently working on) has different requirements: it may for a number of reasons not have the benefit of the setup performed by a complex build process, and have to make the best of what it is given. In other words, it may find a header file not present in the include paths it knows, and have to take its best shot at finding the file itself. I'm currently thinking of using the following algorithm: Start in the directory of the including file. Is the header file found in the current directory or any subdirectory thereof? If so, done. If we are at the root directory, the file doesn't seem to be present on this machine, so skip it. Otherwise move to the parent of the current directory and go to step 2. Is this the best algorithm to use? In particular, does anyone know of any case where a different algorithm would work better?

  • using wildcards in host-aliases for Tomcat's virtual hosts

    - by Marten Sytema
    I want to do the following with Tomcat 5.5: *.mydomain.com should go to my webapp, located at the virtual host mydomain.com. So I have a virtual host mydomain.com, and I want all *.mydomain.com also go there. Now, if I do this, it doesn't pick up the virtual host, and just goes to the default one (which is not set to mydomain.com). How to fix this? I basically would like to allow wildcards in the host alias, or in the virtual host name itself. (The DNS settings are alright by the way)

  • Very High Network out in ec2 instance

    - by Jatin
    I launched an ubuntu-14.04-64bit instance in Amazon EC2 two days back. And I started Tomcat 7.0.54 in that instance and deployed my application war files. It has no other software installed other than tomcat and the default ones. In the past 2 days, its shows 858 GB of Data Transfer(Network Out) from that instance. I have attached a graph of Amazon CloudWatch Metric "Network Out" My application does not do any data download/upload. Its a Java Spring application and the front end is in HTML&Javascript. My application traffic was very low (less than 20 hits) in those 2 days. Is there a way to find out why these data transfers happened and also to find what data has been transferred. If you can see in graph, network out was 20gb per minute. Some more info: Network in was negligible CPU Utilization was very high Everything else was low

  • Strange behavior of excel 2007 on WinXP

    - by bdecaf
    I'm on a machine that had quite some bloat ware and no update in ages. I made all the updates, removed the bloatware and cleaned using ccleaner. So far so good. Now excel shows some really strange behavior when I open .xls files through windows. The current behavior is: it opens a new excel process window which will then stay empty. One has then to drag the xls file into the window to open it. I would like to restore the default behavior. So far I have tried: running the Microsoft Office Diagnosis copied excel related registry keys from a machine with working excel and imported them had a look into the registry entry for .xls files myself - which seems correct. It was of no use and I'm out of ideas. I would try to avoid a reinstall as we have a very bureaucratic IT department and the machine then would be gone for some undetermined time period. So any idea what to do would be great.

  • Bootable SD card still has small memory, even after formating

    - by Inazuma
    I have an SD card which I used to run my RaspberryPi. I wanted to update the copy of raspbian on it, so I formated the card using the software from www.sdcard.com. I followed all the instructions correctly, however the size of my SD card didn't go back to it's default. It is a 4gb SD card, which after it's spell in the RaspberryPi had shrunken to 52mb, which I understand is normal. After formatting, the size rose to 3.69gb. This means that there is not enough space to install a new OS, so how can I make my SD card 4gb again? Any help would be much appreciated!

  • How do programers balance the upper or lower case style to name file or folder between work and life?

    - by sojyq
    I am a programmer from China. And I like to use English words to name my files and folders Whether it is for work or life. For example, suck as Movie, Work, QtProjects, Music and so on.And I keep the habit of initial the first letter for file name or folder name in Windows. But now I work on Ubuntu, and I found that all file name and folder name are lowercase in addition to the default folder such as Music, Movie and so on. And then I realize that in Linux world, most peoloe like to use all lowercase to name their files and folders for two reasons (1. Linux is Case sensitive. 2. It is fast for shell command.). And after work, when I switch from Linux to Windows, I confuse to use all lowercase or the first letter uppercase style to name my files in Windows. I'm caught in a dilemma. I think that all lowercase is more efficiency but the first letter uppercase is more readable. I thought for a long time and want to come up with a good answer to blance the two style name conversion. But I failed. I want to ask you that how you balance the uppercase or lowercase habbit in Windows, Mac, Linux between work and personal life style? Thank you very much! (My current solution is that when I am in Linux, I use all lowercase for files and folders, but when I am in Windows and Mac OS X, I couldn't find a good reason to convince me to use all lowercase ( I think in Windows and Mac OS X, the first letter uppercase style for me is more readable and beautiful).

  • How to close the logon process named NtLmSsp ?

    - by Aristos
    I have a windows 2003 server and time to time I am getting many login failures like this one.

Some notes: I login to the server using tunneling, nothing is open except dns, email, and web ports, not even ftp, and all default ports are change and hidden. I also monitor port scan and capture any one that try to find the hidden ports. Probably it is something open... Thank you in advanced.

  • GUID Partition Table & Linux

    - by Zac
    (1) Is it true that the new GUID Partition Table scheme allows a user to partition a drive however he/she like, outside of the traditional MBR "4 primaries or 3 primaries + 1 extension" paradigm? If so, are there any limitations to the GPT? If my assumption is wrong, what are its advantages over the MBR model? (2) I'm getting a new laptop this week and will be installing Ubuntu (and, more generally, Linux) for the first time ever. Does Ubunutu come pre-configured with MBR as a default? If so, how do I get Ubuntu w/ GPT? If not, how do I specify GPT over MBR? Thanks!

  • Handling UTF-8 with BOM in HTTP

    - by Alois Mahdal
    Say I have a script which at some point serves a plain text file as a content (right after "\n\n"). These files are provided by users, but I can expect they will be UTF-8. So I hard-wire Content-Type: text/plain; charset=UTF-8. But while I can teach users to save everything in UTF-8, I can't be very sure that the files will be without BOM ("\xEE\xBB\xBF"), as at least on Windows, this is not very clearly distinguished in common plain text editors and not every one of them uses the same default. So what about these files created on Windows, where they may/may not start with BOM? Should/will server or UA get rid of this debris for me? Or is it my task to prepare clean UTF-8, i.e. open each file and check whether BOM needs to be removed?

  • Does Ubuntu Server have any sort of cron job to automatically clear /tmp?

    - by DWilliams
    I know it clears out /tmp on reboots, but I haven't been able to find any sort of cron job on my server that clears /tmp. I recently set up a script that writes lots of files to /tmp and my server usually goes several months between reboots so I'm concerned about it being cluttered. I've seen several other distros that have a tmpwatch script installed by default. Ubuntu's repository seems to have replaced tmpwatch with tmpreaper. Is there any mechanism in place on Ubuntu (8.04 currently, soon to be upgraded to 10.04 when I get around to it) to clean up temp files on a server that doesn't regularly reboot or do I need to install tmpreaper?

  • Computer prints blank pages before and after content

    - by Cpt. Jack
    This would seem like a pretty simple question but I have exhausted every idea I can come up with. I bought a brand new Dell Latitude E5410 not too long ago with Windows 7 OS. I installed office 2010 on the machine right away and have had a printing problem since day one. For some reason every time I print a page, a blank page prints out before and after the content print. This also applies to any other application such as notepad or printing an email. If I have a 6 page document, it still prints out one page before and after every content page. Meaning I get my 6 page document along with 12 blank pages. I can't figure out why this would be some sort of default setting or what would cause this printing configuration. I am the only computer on the network that has this problem and quite frankly I'm getting tired of it. Can anyone help me figure this out or steer me in the right direction to correcting this problem?
