• Internet stopped working suddenly on 12.04

  - by Daniel

  My laptop was running smoothly until yesterday. Today, I can't connect to the Internet at home anymore. I am only able to access the router, but no Internet access. A have a Dell Latitude E6320 with Ubuntu 12.04. At my job, I don't have any problems connecting this laptop both via Wireless and Ethernet. At home, if I try connecting it through Windows, it does work fine. I even checked the MAC address and it's OK. My other laptop, which also runs Ubuntu, is not facing this problem. I have already tried to restart and downgrade network-manager package and its dependencies. Can anyone help me please? I am afraid, I will have to reinstall everything.

• function names - "standartised" prefixes

  - by dnsmkl

  Imagine you have such routines /*just do X. Fail if any precondition is not met*/ doX() /*take care of preconditions and then do X*/ takeCareOfPreconditionsCheckIfNeededAtAllAndThenDoX() A little bit more concrete example: /*create directory. Most probably fail with error if any precondition is not met (folder already exists, parent does not exists)*/ createDirectory(path_name) /*take care of preconditions (creates full path till folder if needed, checks if not exists yet) and then creates the directory*/ CheckIfNotExistsYet_CreateDirectory_andFullPathIfNeeded(path_name) How do you name such routines, so it would be clear what does what? I have come to some my own "convetion" like: naiveCreateDirectory, ForceDirectoryExists, ... But I imagine this is very standard situation. Maybe there already exists some norms/convetions for this?

• Nginx + PHP-FPM on Centos 6.5 gives me 502 Bad Gateway (fpm error: unable to read what child say: Bad file descriptor)

  - by Latheesan Kanes

  I am setting up a standard LEMP stack.

• How to set up offline manifest for a web app to run in Safari in iOS?

  - by ahmd1

  I'm currently trying to set up an offline.manifest file for my web app to be used offline on an iOS device. For testing purposes I have a very simple HTML page that I'm trying to add to a home screen. I'm testing it on a live iPhone 4, but after the page is added to the home screen and I put the iPhone in the airplane mode and try to start my web app I get this error: "Turn Off Airplane Mode or Use Wi-Fi to Access Data" and then if I click OK I get: "Cannot Open Web App Name" "Web App Name could not be opened because it is not connected to the Internet" The following is added to the HTML file: <!DOCTYPE html> <html lang="en" manifest="scrts/offline.manifest"> and the offline.manifest is composed as such: CACHE MANIFEST ../pics/bkgnd_iphn_settings.png ../pics/mbl_btn_fb.png ../pics/mbl_btn_twt.png ../pics/icon_57_57_bg.png ../pics/icon_72_72_bg.png ../pics/icon_114_114_bg.png ../pics/icon_144_144_bg.png ../pics/splash_320_460_bg.png ../pics/splash_768_1004_bg.png ../pics/splash_1004_768_bg.png I got all instructions on composing it from here I also adjusted the .htaccess file to add this line: AddType text/cache-manifest .manifest Any idea what am I not doing right?

• How can i fit 2 commands in 1 terminal shortcut

  - by Nicky Bailuc

  10 latest updates and drivers and I need to run a game called unreal tournament, but in terminal it requires 2 commands The first one is to mount into the folder: cd /usr/local/games/ut2004/ and then the second one is to open the actual game: sudo aoss ./ut2004 In one shortcut i can only fit 1 command but both don't fit in is there any way i can turn these 2 commands into one? Perhaps turni9ng on the desktop shortcut already mounted into the folder? Any help would be really appreciated because im getting kinda sick of using the terminal to run it every time.

• Getting a virus is *very* annoying

  - by bconlon

  I spent most of yesterday removing an annoying virus from my PC. I feel slightly foolish for getting one in the first place, but after so many years I guess I was always going to eventually succumb. I was also a little surprised at the failure of various tools at removing it. The virus would redirect the browser to websites including ‘licosearch’, ‘hugosearch’ and ‘facebook’, and the disk would be thrashing away infecting dlls in some way. I had the full up to date version of McAfee installed. This identified that there was an issue in some dlls on the system and was able to ‘fix’ them. But they kept getting re-infected. So I installed Microsoft Security Essentials and this too was able to identify and ‘fix’ the infected dlls. The system scans take forever and I really expected better results. I also tried Malwarebytes, Hitman Pro, AVG and Sophos to no avail. Eventually I thought I’d investigate myself. It turned out that on reboot, the virus would start 3 instances of Firefox.exe which I’m guessing would do bad things including infecting as many dlls on the system as possible. I removed Firefox and the virus cleverly then launched 3 instances of Chrome! So I uninstalled Chrome and yes, it then started to launch 3 instances of iexplore.exe. If I’m honest, by this stage I was just seeing if it would be able to use any of the browsers! As it was starting these on reboot, I looked in my User Startup folder and there was a <randomly named>.exe and several log files. I deleted these and rebooted. When I looked they had been recreated. So I then looked in the registry Run and RunOnce entries: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Sure enough there were entries to run a file in C:\Program Files\<random name folder>\<random name file>.exe. I deleted this and rebooted and it was fixed. I also looked in the event log and found a warning that Winlogon had failed to start the file C:\Program Files\<random name folder>\<random name file>.exe So I also checked HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and this entry had also been changed. Finally I ran a full system scan to clean up any infected dlls. I hope it’s gone for good!  #

• File access forbidden in htpasswd

  - by Nerd-Herd

  I have been using the htpasswd generated in this question and it seemed to have been working well until recently. Since yesterday, I am not able to access the newest file created in the folder ChatLogs(named 10_07_2012.txt). The server returns a 403 Forbidden error saying: Forbidden You don't have permission to access /ChatLogs/2012/07/10_07_2012.txt on this server. I am still able to access older files(until 09 July, 2012). At first I thought it might be because of file permissions, but they are the same as on other 9 files in the folder. What could be the problem? Please Help.

• Reinstall Ubuntu on Custom Partitions

  - by Forerunner117

  I am attempting to reinstall ubuntu 13.04 without losing my installed software and /home docs. I have read countless threads on this same topic, but nothing seems to apply to my situation. When I originally installed, I had created a separate partition for /home, but I am now unsure of which partition that was. Based on the picture below, where should I be installing the new copy? Also, will I run into problems since I am now running 13.10 and want to put 13.04 back on it? Should I grab 12.04 or 13.10 for this reinstall? Picture: http://i.stack.imgur.com/FL2SY.png (Note: I am performing this reinstall due to a complete muck up of my unity/compiz settings and configuration, resulting in no desktop. I've done my best to resolve this problem first before resorting to this.)

• Creating basic ACPI event makes the system unusably slow

  - by skerit

  I want to change a few settings on my laptop when I switch to battery power. I created a new event in /etc/acpi/events/cust-battery and it looks like this: event=battery action=/home/skerit/power.sh I put a simple command in the power.sh file: echo This is a test >> /home/skerit/powertest Now, when I tail this file it shows "This is a test" 4-5 times upon switching to battery power. However, the system becomes totally unstable. It slows down significantly. I can't change anything in the terminal. The terminal and certain parts of the screen (like the gnome system monitor applet) go blank from time to time. What can be the cause of that? It's a simple echo that gets executed a few times!

• Quick path jumping

  - by Sebastian P.

  I was just at a lecture, where I noticed the lecturer using a command (probably aliased) to jump to a specific folder. Example: ~/code$ j sciproj ~/projects/sciproj2011/$ This looked quite slick, so I started wondering: Is this a standard utility, and if so, what is the name? I have two theories as to how it works: It can both create, delete and jump to aliases directly from the command-line in the style of the example, without having to set up aliases in a configuration file or script or whatnot manually. It searches the home directory for a folder matching the name and jumps to it. The second option seems a bit slow, however, so the first would be preferred.

• Ubuntu One not syncing and not providing feedback

  - by Joe

  Firstly, I apologize for not being more specific with my problem, but Ubuntu One is just not providing me with any information. It appears to be working, it states that "syncronization in progress..." but it never actually syncronizes (by never I mean 3 days). When I first selected a folder to sync using Ubuntu One it took on the order of hours to sync over 500MB of files - it uploaded the folder hierarchy first and populated the folders over a few hours. That is not happening at all now. Please let me know if there is a way I can get more information out of Ubuntu One that I can post and hopefully resolve this issue. Thanks, Joe

• How can I instruct nautilus to pre-generate thumbnails?

  - by Glutanimate

  I have a large library of PDF documents (papers, lectures, handouts) that I want to be able to quickly navigate through. For that I need thumbnails. At the same time however, I see that the ~/.thumbnails folder is piling up with thumbs I don't really need. Deleting thumbnail junk without removing the important thumbs is impossible. If I were to delete them, I'd have to go to each and every folder with important PDF documents and let the thumbnail cache regenerate. I would love to able to automate this process. Is there any way I can tell nautilus to pre-cache the thumbs for a set of given directories? Note: I did find a set of bash scripts that appear to do this for pictures and videos, but not for any other documents. Maybe someone more experienced with scripting might be able to adjust these for PDF documents or at least point me in the right direction on what I'd have to modify for this to work with PDF documents as well.

• Ubuntu One not syncing fully

  - by wurlyfan

  I have uploaded several folders of data to Ubuntu One from my desktop computer, over the last few weeks, and I can see that all the contents are there when I look at my account on the web. When I look at my laptop (connected to the same account), one of the first folders I uploaded hasn't downloaded completely. New folders added from either device seem to sync correctly, but this one older folder remains almost empty, even though the control panel says file syncing is up-to-date. I have plenty of space available. Stopping and restarting the sync daemon and rebooting the laptop are both ineffective. What can I do to make this folder sync fully? I don't want to risk losing the data (which now exists only in Ubuntu One), and I don't have a lot of broadband data to play with. I've seen several bugs relating to this sort of issue but they're all quite old and apparently fixed, while this is happening on new 13.04 installations on both desktop and laptop.

• GitLab on a fresh Ubuntu 13 EC2 instance

  - by Polly

  I've spun up a fresh Amazon EC2 instance for a micro Ubuntu 13 server to be used as a GitLab server. I know the specs are a little low, but it should serve well for my purposes. It has an elastic (static) IP address that I have created an A record for git.mydomain.com. The first thing I did to the instance was add 1GB of swap to keep it happy from a memory perspective. I then set the hostname of the box to be git.mydomain.com and followed https://github.com/gitlabhq/gitlabhq/blob/6-2-stable/doc/install/installation.md to the letter. Everything seems to have worked, except for the web server side of things. Doing a gitlab:check shows the following: Checking Environment ...

I'm sure I'm missing something simple, but I've been through every relevant link I can find and have had no positive results; thank you in advance for any help!

• Is adding in the header the license type enough to say: "my code is licensed"?

  - by silverfox

  I read on various sites about licenses. I did just put the license type in the header file (in my case a javascript file, open-source): /* * "codeName" "version" * http://officialsite.com/ * * Copyright 2012 "codeName" * Released under the "LICENSE NAME" license * http://officialsite.com/LICENSE NAME */ javascript code ... In the same folder I leave a copy of the license. The listing of the folder looks like this: * codeName.js * LICENSE In the file LICENSE is the full text of the license my code uses. What I cannot find anywhere that says is this is enough to say my code is licensed (the case of open-source). Is something more required?

• Ubuntu samba file and print server

  - by Gerd

  I am using an old Dell desktop PC as a samba file and print server for a Windows 7 network. The version of Unbuntu I am running is 12.04 which seems to big for the RAM and disk space I have available. Unbuntu 12.04 runs very very slow, the printing over the home network works at a quite acceptable speed. I have two problems: SLOW Ubuntu and I cannot update samba. The update manager tells me "update failed". So my two questions: Is there anything I can remove from the standard 12.04 installation to make Ubuntu run faster and should I uninstall and the reinstall samba to overcome the "update failed" problem? I hesitate, as printing and file serving works somehow and I don't want to loose that. I know I should give you more information to give me answers. But what would you need to know? I am not a natural Linux user. Windows 7 is still my home. Thanks in advance, Gerd

• How to access localhost remotely - Wordpress?

  I have installed a LAMP stack (sudo tasksel install lamp-server) and wordpress (sudo apt-get install wordpress), but now, I would like to access my server remotely, to be used as a home fileserver. For example, my public ip is 82.16.xxx.xxx. Opening it in firefox with the suffix :8080 brings up my router config page..? Do I have to set up port forwarding? BTW. Accessing via localhost/wordpress/ works fine, I would just like to access my files while away from home.

• "Failed to mount Windows share" error in Samba

  - by Ranjith R

  This is the situation. There are 3 machines in the office. The Operating systems on them are respectively, Linux mint Ubuntu 12.04 Windows Vista The Ubuntu (#2) machine is supposed to be the common file server between the machines #1 and #3. Machine #2 has two hard disks. One is a 500 GB NTFS empty drive and the other is a 160 GB ext4 drive. My plan is to make the 500 GB as the file sharing disk. When I share a folder like ~/Documents using Nautilus context menu on machine #2, I can access the files easily on both #1 and #3, but when I try to share some folder on 500 GB disk, I get an error on machine #1 that says Failed to mount windows share I do not mind formatting the drive to ext4 if needed, but I am sure that something simple is wrong. EDIT I took @Marty's comment as a hint and used ntfs-config to configure automount of that partition. It is working now. Thanks

• Microsoft Office 2013 Takes New Approach

  You can check out an article from Computerworld for a good look at the questions and answers about the new software. For instance, you've probably noticed that I'm not giving the full name. That's because Microsoft seems to be using several names. If you go the traditional route and pay the one-time upfront fee for the shrink-wrapped edition, it's Office 2013. There's also a tablet version called Office Home and Student 2013 RT - but that won't include the iPad, or at least not at first. The consumer preview, which I'll be linking to in a minute, is dubbed Office 365 Home Premium. There ...

• Disable automatic starting of sshd?

• Nautilus left pane does not expand

  - by dn.usenet

  I would prefer the left pane of Nautilus to behave like Windows file manager. It should have expandable/collapsible trees, and if I have /home/mydir-1, /home/mydir-2, I should be able to see them both in the left pane. When I click on one of them, the files in that dir should show in the right pane. If Nautilus can't do it, please suggest a better file-manager which does. I would rather not open 3 panes in Nautilus to do what two panes do just fine in Windows File Manager. Secondly how can I open two instances of Nautilus? And if it isn't possible with Nautilus, could it be done with some other file manager?
