  • How do I reset my PYTHONPATH?

    - by Underyx
    Somehow my PYTHONPATH environment variable got emptied, and now I can't import some downloaded modules. I've tried running the following command to reinstall all Python packages, but it didn't set the variable back to its original value: dpkg-query -W -f '${package}\n' | grep python | xargs -I % sudo apt-get install % --reinstall How do I reinstall the packages so that this gets sorted out? The (Vagrant) box is running Ubuntu 12.04.

  • Is there a way to diagnose a tar file when, on extract, files are missing but no errors are given?

    - by ljvillanueva
    I have tar files where I archive about 250 files, each about 80 Mb, without compression. In a few cases tar is only returning some of the files. For example, when doing an extract of the file using: tar -xvf 356.tar I got only 103 files, when it should return 255 files, but tar does not give me an error. Furthermore, the tar archive is 15.8 Gb while the extracted folder is just 6.4 Gb. The tar files were created using tar -cvf 356.tar 356 where 356 is the name of the folder. All the steps where done in the same machines, under Ubuntu 6 and newer. Any ideas if there is a way to recover the files that are not being extracted?

  • Why doesn't my cron.d per minute job run?

    - by Travis Griggs
    I have thrown a bunch of darts trying to get a python script of mine to execute every minute. So I thought I'd simplify it to just do the "simplest thing that could could possibly work" once per minute (I'm running debian/testing). I created a single line file in /etc/cron.d/perminute: * * * * * /bin/touch /home/me/ding_dong It's owned by root, and executable (not sure if either of those matter). And then I did: sudo service cron reload And then sit back and start running ls -ltr again and again in my home directory (/home/me). But my ding_dong file never shows up. I know if I do a sudo /bin/touch /home/me/ding_dong, it shows up right away. Obviously missing something stupid here.

  • Is there a decent diagram of packet flow for a modern era (2.6+) iptables setup?

    - by stsquad
    I'm currently trying to debug a particularly hairy set of DNAT based iptables rules (the UDP reply never makes it back to the original requester) and I'm struggling to visualise the packet flow through all the numerous tables involved. So far Google'ing has shown me old 2.4 based ipchains ones. The netfilter site has some good text docs but is short on diagrams and a number of the external links are now dead. So is there a canonical diagram for iptables packet flow, preferably showing how NAT/Masqueraded packets are also dealt with?

  • Where can I download mod_shaper for proftpd?

    - by lorus
    www.castaglia.org/proftpd/ says: mod_shaper is distributed with the proftpd source code but in the latest src from ftp://ftp1.at.proftpd.org/ProFTPD/distrib/source/proftpd-1.3.2e.tar.gz there is no mod_shaper.c inside ... so where can I get this mod?

  • Run script on login with ssh

    - by user912447
    I have a feeling this is quite easy to do but every solution found on google has to do with adding a script to be run whenever someone logs into the machine. What I am looking for is a way to run a script when only I log into the machine. I ssh into a shared computer and need to have it load a couple modules for me and I imagined the easiest way to do this would to just run a script on login. Is there a simple way?

  • How to change the X-Windows default border width for all window frames in Ubuntu using Gnome 2.28

    - by Heston T. Holtmann
    Way back from Windows 3.x days to the latest 64bit Windows 7 (classic/standard theme).. there is a way to make the window edge border wider then 1 pixel... I often use 3 to 5 pixel to make it easy to grab on hi-resolutions displays and hi DPI monitors. There doesn't seem to be an easy or obvious way to do this with the Gnome X-Windowing system? Does any one know how?

  • Howto setup a `veth` virtual network

    - by Reinder
    I'd like to setup three virtual network interfaces (veth) which can communicate with each other. To simulate a three node cluster, each program then binds to one veth interface. I'd like to do it without LXC if possible. I tried using: Created three veth pairs: sudo ip link add type veth Created a bridge sudo brctl addbr br0 Added one of each pair to the bridge: sudo brctl addif br0 veth1 sudo brctl addif br0 veth3 sudo brctl addif br0 veth5 Configured the interfaces: sudo ifconfig veth0 10.0.0.201 netmask 255.255.255.0 up sudo ifconfig veth2 10.0.0.202 netmask 255.255.255.0 up sudo ifconfig veth4 10.0.0.203 netmask 255.255.255.0 up Then I verified if is works using: ping -I veth0 10.0.0.202 but it doesn't :( The I added IP addresses to the veth1,veth3,veth5 and br0 interfaces in the 10.0.1.x/24 range. But that doesn't help. Any ideas? or a guide, all I find in how to use it with LXC. Or am I trying something that isn't possible?

  • How to prevent Vista from entering Sleep mode when certain conditions exist?

    - by idyllhands
    Mainly, I would like to prevent my laptop from entering Sleep mode when I am playing music or streaming video. This is on my laptop, so another option that would work would be to prevent sleep mode whenever the laptop is plugged into my tv via HDMI (ie when HDMI port is in use). Or prevent sleep mode whenever there is audio playing.. I am soon upgrading to Windows 7, so solutions using 7 would be great also/instead. Thanks!

  • Ubuntu USB flash boot drive gets spontaneous "Unhandled sense code" error and causes drive to switch to Write protected

    - by Steve
    What happens is that the system runs fine for several days or even a week and then suddenly the root file-system / goes read-only. Looking at the syslog it shows that there was an 'Unhandled sense code'.

  • What are the different file permission codes and what do they mean?

    - by zeckdude
    I am working with a file upload script. I am currently uploading a file and then trying to echo out an anchor linking to that file, but since I used mkdir() with 0700 permissions to upload the file, it won't allow me access to view the file. I am pretty sure the problem I am experiencing is because of the file permission code I used. The problem is I just don't know what all the different file permission codes are and what they mean. Can somebody please list out all the different file permissions and what they each do?

  • Tcp Port Open by Unknown Service

    - by Singularity
    Running openSUSE 11.2 x86_64. Here's what a nmap of my IP provides: PORT STATE SERVICE 23/tcp open telnet 80/tcp open http 2800/tcp open unknown 8008/tcp open http I would like to know How to view What service is causing Port 2800 to be opened? A few search engine results led me to believe that it is supposedly a port opened by a Trojan called "Theef". If it is indeed a Trojan, what can be done to weed it out? Is my desktop's security compromised?

  • Is it possible to have environment variables in the path of the working directory : PS1?

    - by mthpvg
    I am on Lubuntu and I am using bash. My PS1 (in .bashrc) is : PS1="\w> " I like it because I need to paste the working directory all the time. The problem is that the path is always very long and since I use terminator I only have half of my screen's width available to display it... it is ugly and annoying. My command prompt looks like that : /this/is/a/very/long/path/that/i/want/to/make/shorter > I'd like to set in my environment variables : $tiavl=/this/is/a/very/long And then I'll get : $tiavl/path/that/i/want/to/make/shorter > The goal is to have something shorter in the command prompt but I still want to be able to copy paste it and do : cd $tiavl/path/that/i/want/to/make/shorter It is a bit like with $HOME : ~/path/that/i/want/to/make/shorter > I know where I am and I can copy paste the ~. Thanks.

    - by Somebody still uses you MS-DOS
    My question mark key in my keyboard isn't working. ("?"). I've tried to use xev and showkey -k to try to identify at least it's code and manually use xmodmap to mao this key. Unfortunately, the keys aren't being detected in neither utilities. I'm using Ubuntu 10.04 in a Virtual Machine, and my Kernel is 2.6.32-22-generic. What can this be? It's not a special multimedia key, it's a simple one. I would like to understand what exactly is happening so at least I can try to better debug this issue.
