• Using the right folder for the right job. Article link, please?

  - by Droogans

  There are specific folders designed for specific tasks. /var/www holds your web sites, /usr/bin contains files to run your applications...yet I still find myself putting nearly all of my work in ~. Is it possible to overuse my home directory? Will it come back to haunt me? Anyone have a good link to an article of best practices for organizing your files so that they are placed in their "correct" place? Is there even such a thing in Linux? I am referring specifically to user-generated content. I do not compile applications from source, I use apt-get for those tasks. This article has a great introduction to what I'm looking for. Table 3-2, "Subdirectories of the root directory" is the sort of thing I'm looking for, but with more details/examples.

• DokuWiki Segmentation Fault On Radius Auth

  - by mrduclaw

  I'm running x64 Ubuntu 12.04. I did a simple apt-get install dokuwiki to install DokuWiki. And I'm trying to follow the directions located here: http://www.dokuwiki.org/auth:radius to get Radius authentication working. Things seemed to install OK. Under Configuration Manager I selected Authentication backend to be "Radius" and filled in the Radius details at the bottom. Now, however, whenever I try to log into the Wiki, my browser gives me the following error: No data received I checked /var/log/apache2/error.log and see this: [Tue Jul 10 22:22:14 2012] [notice] child pid 5270 exit signal Segmentation fault (11) I'm fairly sure the Radius server is setup correctly as it correctly authenticates with my squid proxy and other stuff on the network. But this is about the extent of my Linux troubleshooting skills. Can anyone suggest steps for me to follow to help track down what's causing apache2 to segfault short of attaching with gdb and issuing a set follow-fork-mode? I'm also open to just hearing suggestions for simila

• Test A SSH Connection from Windows commandline

  - by IguanaMinstrel

  I am looking for a way to test if a SSH server is available from a Windows host. I found this one-liner, but it requires the a Unix/Linux host: ssh -q -o "BatchMode=yes" user@host "echo 2>&1" && echo "UP" || echo "DOWN" Telnet'ing to port 22 works, but that's not really scriptable. I have also played around with Plink, but I haven't found a way to get the functionality of the one-liner above. Does anyone know Plink enough to make this work? Are there any other windows based tools that would work? Please note that the SSH servers in question are behind a corporate firewall and are NOT internet accessible. Arrrg.

• Yahoo marked my mail as spam and says domainkey fails

  - by mGreet

  Hi Yahoo is marking our mail as spam. We are using PHP Zend framework to send the mail. Mail header says that Domain Key is failed. Authentication-Results: mta160.mail.in.yahoo.com from=mydomain.com; domainkeys=fail (bad sig); from=mydomain.com; dkim=pass (ok) We configured our SMTP server (Same server used to send mail from zend framework.) in outlook and send the mail to yahoo. This time yahoo says domainkeys is pass. Authentication-Results: mta185.mail.in.yahoo.com from=speedgreet.com; domainkeys=pass (ok); from=speedgreet.com; dkim=pass (ok) Domainkey is added in mail header on our server which is used by both outlook client and PHP client. yahoo recognize the mail which is sent from outlook and yahoo does not recognize the mail from PHP client. As far as I know, Signing the email is done on the server side with help of domain key. PHP and Outlook uses the same server to sign the mail. But why yahoo handling differently? What I am missing here? Any Idea? Can anyone help me?

• Getting PHP to work with apache to run .php files through browser

  - by Kevin Duke

  I have VPS running Debian 5.0 (I think) and I would like to get it to run PHP files. I was told it needed to be configured with Apache. I tried entering the command apt-get install apache2 php5 libapache2-mod-php5. But there was no change. Console output: http://pastebin.com/sVMWq6mA This is everything in my /etc/apache2/mods-enabled: http://img35.imageshack.us/img35/6474/modsb.jpg My webserver can be accessed here: http://206.217.223.136/test/ In my test.php file I have the code : <?php phpinfo(); ?> but instead of displaying the page, it tries to download it. How can I fix this?

• Allow opening a new tab with Ctrl+T on all websites in Firefox

  - by Martin J.H.

  In Firefox, certain websites and plugins (Adobe PDF Plugin) appear to "capture" the Control key, so that when I try to open a new tab using "Ctrl+t", nothing happens - or worse, something unexpected happens. Examples: On the Codecademy site, while editing code, Ctrl+T either does nothing, or (when Flash is disabled) switches the position of the two characters next to the cursor. When viewing PDF's with the Adobe PDF Plugin, Ctrl+T does nothing. Is there a way to disable this "feature"? I would like "Ctrl+t" to always "talk" to Firefox! Edit: After searching superuser deeper, this question is very similar to the questions: "How to prevent keystroke grabbing/hijacking by websites in Firefox?" "How do I prevent pages I visit from overriding selected Firefox shortcut keys?". The answers to these questions are interesting and relevant, but do not give a method on how to disable combinatinos such as "Ctrl+t". Maybe a modified Greasemonkey script is the easiest solultion. Edit 2 - Attempt at a solution The following UserScript (Use GreaseMonkey to install it) successfully captures Ctrl+t on some sites (Google Search site, for instance - PopUp "Gotcha" appears), but not on the Codecademy site. I found another question pertaining to this subject here: "How to forbid keyboard shortcut stealing by websites in Firefox". It was raised in 2010, and the consensus was: It can't be done. // ==UserScript== // @name Disable Ctrl T interceptions // @description Stop websites from highjacking keyboard shortcuts // // @run-at document-start // @include * // @grant none // ==/UserScript== // Keycode for 't'. Add more to disable other ctrl+X interceptions keycodes = [84]; var lastPressedButton = [0]; document.addEventListener('keydown', function(e) { //uncomment to find out the keycode for any given key // alert(e.keyCode ); if (keycodes.indexOf(e.keyCode) != -1 && e.ctrlKey) { e.cancelBubble = true; e.stopImmediatePropagation(); alert("Gotcha!"); } return false; });

• OpenWRT + OpenVPN client forwarding from lan to vpn not working

  - by Dariusz Górecki

  I've OpenWRT router with Backfire 10.03.1-rc3 (arch:brcm 2.6 kernel) I've set up an OpenVPN client connecting my router with workplace lan, and it works nicely, I can connect from router to networks (several) in workplace. My OpenVPN client uci-config looks like: config 'openvpn' 'stream_client' option 'nobind' '1' option 'float' '1' option 'client' '1' option 'reneg_sec' '0' option 'management' '127.0.0.1 31194' option 'explicit_exit_notify' '1' option 'verb' '3' option 'persist_tun' '1' option 'persist_key' '1' list 'remote' 'remote.address.cutted' option 'ca' '/lib/uci/upload/cbid.openvpn.stream_client.ca' option 'key' '/lib/uci/upload/cbid.openvpn.stream_client.key' option 'cert' '/lib/uci/upload/cbid.openvpn.stream_client.cert' option 'enable' '1' option 'dev' 'tun1' I've set the 'STREAM_VPN' Zone to allow in/out traffic, and I've added rules for zone-to-zone lan<-vpn and vpn<-lan config 'zone' option 'name' 'stream_vpn' option 'network' 'stream_vpn' option 'input' 'ACCEPT' option 'output' 'ACCEPT' option 'forward' 'REJECT' config 'forwarding' option 'src' 'lan' option 'dest' 'stream_vpn' config 'forwarding' option 'src' 'stream_vpn' option 'dest' 'lan' And interface config: config 'interface' 'stream_vpn' option 'proto' 'none' option 'ifname' 'tun1' option 'defaultroute' '0' option 'peerdns' '0' Now, from my router everything works nicely, the problem is that I cannot connect from computer inside a lan to hosts in networks provided by vpn connection :/ What I've missed, or what I'm doing wrong? And how can I force using specified DNS when connected to vpn? (I know that sever should use PUSH DNS option, but is PUSHes only routes)

• How to setup etckeeper with Mercurial in Ubuntu?

  - by DeletedAccount

  Hi, I'm interested in installing etckeeper with Mercurial in my Ubuntu system. My reason is that I don't know how to use Git and don't want to learn at the moment. If I check the package description it sounds promising: kent@rat:~$ apt-cache search etckeeper etckeeper - store /etc in git, mercurial, or bzr I'm wondering how to continue on from here? I've tried Googling but I haven't found anything for the Ubuntu + etckeeper + Mercurial combination. (If you know of a good tutorial for this situation, a link is an excellent answer. No need to re-iterate.)

• sudoer scheme for a web developer that retains future control of a server?

  - by Tchalvak

  Background I have a server that I'm looking to set up, and provide access to another web developer. I don't want to put many constraints on him, though I wouldn't mind isolating the site that he'll be developing from others on the server that I will develop. The problem Mainly what I want is to make sure that I retain control over the server in the future. I want to reserve the ability to create/promote/demote and other administrative functions that don't deal with web software. If I make him an admin, he can sudo su - and become root and remove root control from me, for example. What is a good setup for the sudoers file so that he can do things like: *install software (through apt-get) restart apache access mysql configure mysql/apache reboot edit web development configuration type files in /etc * And can't do things like: take away other admin permissions change the root password have control over other security/administrative functions Example sudoer files that accomplish something like that could be useful, I'm sure that people have needed to do this before.

• How can I perform a controlled shutdown of a virtualbox guest using VBoxManage?

  - by Bryan

  I'm currently testing Ubuntu 10.04, and have install the VirtualBox software. I have also installed Ubuntu 10.04 as a VirtualBox guest running on the host system. I've installed the VirtualBox Utils into the guest OS, as follows: sudo apt-get install virtualbox-ose-guest-utils What I want to be able to do is to initiate a controlled shutdown of the guest, from the host system using the VBoxManage command. I first tried this command: VBoxManage controlvm guest poweroff which worked, but didn't initiate a controlled shutdown, it effectively pulls the plug on the guest. I've since found that this command should do the trick: VBoxManage controlvm guest acpipowerbutton but this doesn't appear to do anything. Can anyone tell me what I'm doing wrong? p.s. I don't want to use SSH & Certificates to do this, as I'm also going to be running Windows guests, and I want the solution to work for all guests.

• /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor disappeared on ubuntu 11.10

  - by Bob

  I have an Ubuntu 11.10 server that has been up for 210 days. I have been frequently doing apt-get upgrade every few weeks, and this time I noticed that my server load average just shot up. The last time this happened between upgrades, it was because the cpu scaling governor was set to ondemand. But this time when I tried to list the contents of /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor the file is missing. There isn't even a cpufreq folder anymore! How do I fix this and ensure there is no cpu scaling going on?

• SSH through standard Belkin router to Asus Tomato router

  - by Luke

  I've set up SSH on the Tomato firmware on an Asus N10, via port 22 with key authentication. I've tested the keys by connecting with putty directly to the router when connected to its network. That works OK. But this router is behind a Belkin (F5D7632-4) router which also acts as modem and when I try to connect through with the (dynamic) public IP it times out. I'm guessing it's something to do with the NAT? My putty settings are taken from various online tutorials, but it's set up for port 22, with the correct key as mentioned. The Belkin router has port forwarding to the Asus (192.168.2.3) for port 22 TCP and UDP set up. It's now tough to see what to do in order to connect to the Asus router with an external IP - if it's even possible. Ideally I would have liked to have only needed to use the Asus router, but as it doesn't act as a modem, I need to connect it to the Belkin to use Tomato's features. Perhaps there's a solution here too? Network: Internet -> Belkin modem/router -> Asus router (Tomato SSH) -> Devices

• How to get the Three.js import/export scripts into Blender on Ubuntu?

  - by Bane

  I have been working with 3D primitives in Three.js, but now I want to import some models. I plan on using Blender, which I have just downloaded with: sudo apt-get install blender However, I was instructed to put the import/export scripts in the .blender/2.62/scripts/addons folder, but it does not exist! .blender/2.62 does exist, but it only has a config folder. The next thing I did is manually changed the script search path in Blender's preferences from // to my homefolder/scripts, which contained the required io_mesh_threejs folder (which, in turn had the .py scripts inside). I saved the changes, restarted Blender, but still nothing: in the menu there is no mention of Three.js at all! What do I do? It would be great if I knew the installation path for Blender, because maybe I could put those scripts there manually. Where should it be installed? EDIT: these are the scripts I'm talking about, along with the instructions: https://github.com/mrdoob/three.js/tree/master/utils/exporters/blender.

• knife on Windows inconsistently reads ~\.ssh\knife.rb on Management Workstation

  - by gWaldo

  I am implementing a new instance of (Open-source v10.12) Chef in an existing environment. Currently the environment is mostly Windows, but more Linux is being introduced. I have used Chef in a previous gig, however that was a *nix-only environment. Because this is a primarily-Windows environment, my main workstation is Windows 7 (x64), and I use Powershell as my main terminal. I created a ~\.chef directory, populated with a knife.rb and my client.pem file. When I run knife client list from ~, I get the expected results. I keep my work in Dropbox just in case my laptop should fail or be stolen. When I run knife client list from the repo directory (C:\Users\waldo\Dropbox_company\projects\chef`), I get ERROR: Your private key could not be loaded from C:/home/waldo/.chef/waldog.pem Check your configuration file and ensure that your private key is readable (Note that the path is incorrect) This is the progression as I walk up the tree towards my ~ running knife client list: C:\Users\waldo\Dropbox\_company\projects\ => Above error C:\Users\waldo\Dropbox\_company\ => Above error C:\Users\waldo\Dropbox\ => It works! (Expected results) C:\Users\waldo\ => Expected results C:\Users\waldo\Documents\ => Expected Results C:\Users\waldo\Documents\GitHub => Expected Results C:\Users\waldo\Documents\GitHub\aProject\ => Expected Results What. The. Eff! Now, I know that I can add -c path\to\knife.rb, but that's a HUGE PITA. Question is: Why is knife inconsistently reading my ~\.chef\knife.rb, and how can I get around that without incurring carpal tunnel?

• Coming from Win XP to 7 and having new accessibility software problems

  - by Anonymous Jones

  I just switched from Windows XP Pro SP3 (32bit) to Windows 7 Ultimate (32bit) on a new PC. Now, both the new onscreen keyboard and a utility for sending mouse clicks are being problematic. The problem with 7's OSK is that some things I type only work intermittently or just dodgily. Like Alt+Tab with multiple Tabs, other Alt/Ctrl/Shift/Win key combinations, and the context menu key. Sometimes apps will not take focus for input at all. I use the OSK it in 'hover' mode, on 0,5 seconds. The clicking tool is Point-N-Click, which sends clicks when I dwell anywhere for 1.25 seconds with the mouse pointer. http://www.polital.com/pnc/ The problem with it is that sometimes it fails to click. Most often this happens in some of the control panel sections, on the taskbar, and when UAC pops up. It seems to occur in conjunction with OSK usage a bit too, I think. I'm using an Administrator account. DEP and UAC settings are default. What can I do to fix or work around either of these problems? I'm disabled so this really is killing usability.

• Some process/service/driver repeatedly presses F5

  - by VitalyB

  Hi everyone, I have the strangest problem that started 2 days ago (Windows7, 64bit). SOMETHING causes my F5 key to be constantly pressed. Rebooting helps, but only for a while, it keeps coming back to that. So far I've tried to disconnect and reconnect the keyboard (physically), however, disconnecting the keyboard doesn't actually do anything. Reconnecting it back again, causes the F5-pressing to stop, but not for very long (seconds/minutes). I'd really like to avoid a binary search for the programs (process closing/keyboard switching/etc) before I can, at the very least, identify the source of the keypress. Is there an application that can show me what is causing a key press? E.g is it the keyboard driver, or some process that executes SendKey repeatedly for reasons unknown. Thanks! P.S FYI, having F5 causes the strangest side effects. Task Manager refreshes very very quickly (as F5 is refresh), the desktop is constantly flickering and all the browsers stop working as they keep trying to refresh. I was lucky to find out what the heck is happening only because I started notepad and saw that current date/time started to appear constantly. If not that, I'd still be wondering.

• How can I display additional boot and shutdown information on the Windows 7 welcome screen?

  - by Daniel Saner

  There is a small tweak, I believe it is a registry key, that allows to display additional information on the Welcome and Shutting down screens of Windows 7 (and most likely Vista, too). I have activated this tweak on one of my systems; unfortunately I forgot how I did it, and I can't seem to find the website that originally gave me that information. Usually, the Windows 7 welcome screen will just display "Welcome" when logging in. With the tweak activated, my Welcome screen gives status information such as "Loading user settings" or "Preparing desktop". When shutting down, the default screen simply says "Shutting down". With the tweak activated, it gives additional status information such as "Stopping Windows services". This appears the same way that Windows gives information when updates are installed or configured during the startup or shutdown procedure, and I find them quite helpful in getting a feel for what task takes how long during that process. The only setting I was able to find is the Boot log checkbox on the Boot tab of the msconfig application. However, this results in Windows displaying console logs of drivers it is loading, etc., instead of the animated Windows title. This is NOT the setting I am looking for. The "additional boot information" setting that I have activated on this system still displays the regular animated Windows logo, and only replaces the strings displayed on the blue Welcome and Shutdown screens. Could someone direct me to the registry key (or whatever setting) that is used to get this behaviour? Edit: Here are a few pictures of the enhanced Welcome and Shutdown screens taken with my mobile phone—they're in German though. Login screens "Waiting for User Profile Service" and "Preparing desktop": Logout screen "Stopping Windows services":

• Using NOPASSWD for specific commands in sudoers file, PASSWD for all others

  - by jberryman

  I would like to configure sudo such that users can run some specific commands without entering a password (for convenience) and can run all other commands by entering a password. This is what I have, but this does not work; a password is always required: Defaults env_reset Defaults timestamp_timeout = 1 root ALL=(ALL:ALL) ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) NOPASSWD: /usr/sbin/pm-suspend, /usr/bin/apt-get, PASSWD: ALL #includedir /etc/sudoers.d Note that this is a debian system which uses this adding users to the "sudo" group method. Thanks.

• InstantSSL's certificate no different than a self signed certificate under Nginx with an IP accessed address

  - by Absolute0

  I ordered an ssl certificate from InstantSSL and got the following pair of files: my_ip.ca-bundle, my_ip.crt I also previously generated my own key and crt files using openssl. I concatenated all the crt files: cat my_previously_generted.crt my_ip.ca_bundle my_ip.crt chained.crt And configured nginx as follows: server { ... listen 443; ssl on; ssl_certificate /home/dmsf/csr/chained.crt; ssl_certificate_key /home/dmsf/csr/csr.nopass.key; ... } I don't have a domain name as per the clients request. When I open the browser with https://my_ip chrome gives me this error: The site's security certificate is not trusted! You attempted to reach my_ip, but the server presented a certificate issued by an entity that is not trusted by your computer's operating system. This may mean that the server has generated its own security credentials, which Google Chrome cannot rely on for identity information, or an attacker may be trying to intercept your communications. You should not proceed, especially if you have never seen this warning before for this site.

• Upgrade using downloaded $40 to Win8 x64 to blank SSD using only retail 32Bit XP install CD

  - by Ron

  Here is my situation. Purchase the downloadable $40 UPGRADE version of Windows 8. Install this upgrade to a new/blank SSD drive WITHOUT prior installation of retail version of XP/service pack 3 (prefered). I have the retail purchased 32Bit XP installation media and I also have a slipstreamed disc that contains service pack 2. This 32bit XP license was installed to a desktop PC that I have NOT used for years (its broke). Questions: Can I upgrade using the $40 download upgrade version from retail 32Bit XP to 64Bit Windows 8 directly to new SSD? without first installing 32bit XP to new SSD? If 32bit XP needs to be installed to perform the upgrade to 64bit Win 8 is service XP service pack 3 still available; likewise, if the boxed retail version of XP 32bit is required to be pre-installed to the new SSD before attempting the downoladed $40 upgrade to 64Bit Win, can a clean install be performed or is a undesired actual upgrade performed? From what I have read this is way to complicated. Ideally, I should be able to install $40 upgrade version Win 64bit directly to new/blank SSD, then during the license verification process enter both the Win8 64Bit upgrade key and retail XP 32bit key (over internet or phone call). Thanks Very Much In Advance for any insight!! Regards, Ron

• SSH sometimes screws up connection when terminal overflows?

  - by SeveQ

  I've got a problem with SSH on a Debian Lenny based server (it's a vHost within a Xen environment, booted on a Xen kernel). I hope someone can help me with this. The SSH connection seems somehow getting screwed up frequently when the terminal overflows (new lines beyond the bottom of the terminal, usually forcing it to scroll). The connection gets lost but not regularly disconnected. It nearly always happens when I do the following: an existing SSH connection gets disconnected (regularly) I order putty to reestablish the connection login-prompt appears at the very bottom of the putty terminal window I enter my login-name, press the enter key I'm asked for the password, I enter it, press the enter key and BOOM! Nothing more happens. I have to reconnect again. So it is reproducable. I'm not totally sure if the connection crashes before or after I enter the password. Furthermore it also happens when there is much text to be displayed (for example when I compile something or do an ls -l on a directory with many entries). Using 'screen', however, helps to reduces the frequency of occurence but doesn't solve the problem completely. It's occurence is independent from which terminal software I use. I mostly use putty but it also happens with other clients. I certainly hope somebody can help me solving this problem. Thanks in advance! //edit: I've just made a Wireshark trace of the ssh connection and there is nothing, I repeat, nothing different between the working and the failing connection (at least aside from frame numbers, ports and times that obviously can't be equal). This leads me to the assumption that the error has to happen on the server's side.

  I've written a script to add CVS and SVN users on a Linux server (Slackware 14.0). This script creates the user if necessary, and either copies the user's SSH key from an existing shell account or generates a new SSH key. Just to be clear, the accounts are specifically for SVN or CVS. So the entry in /home/${username}/.ssh/authorized_keys begins with (using CVS as an example): command="/usr/bin/cvs server",no-port-forwarding,no-agent-forwarding,no-X11-forwarding,no-pty ssh-rsa ....etc...etc...etc... Actual shell access will never be allowed for these users - they are purely there to provide access to our source repositories via SSH. My problem is that when I add a new user, they get an empty password in /etc/shadow by default. It looks like: paddycvs:!:15679:0:99999:7::: If I leave the shadow file as is (with the !), SSH authentication fails. To enable SSH, I must first run passwd for the new user and enter something. I have two issues with doing that. First, it requires user input which I can't allow in this script. Second, it potentially allows the user to login at the physical terminal (if they have physical access, which they might, and know the secret password -- okay, so that's unlikely). The way I normally prevent users from logging in is to set their shell to /bin/false, but if I do that then SSH doesn't work either! Does anyone have a suggestion for scripting this? Should I simply use sed or something and replace the relevant line in the shadow file with a preset encrypted secret password string? Or is there a better way? Cheers =)
