• eCryptfs on ubuntu server : How to keep the home mounted without being over ssh?

  - by Bebeoix

  I have a daemon program who need to read in a file who is saved somewhere in my home folder. But every time I close my ssh connection, this daemon can't read the file because it appear that eCryptfs unmount the home. Maybe there is an option to force eCryptfs to not only mount with an ssh connection ? I didn't found it. Thanks. PS : I know this thread, http://askubuntu.com/questions/165608/why-is-ecryptfs-only-mounting-private-home-directory-over-ssh, but this is not the proper/good way to deal with the request.

• How to quickly search through a very large list of strings / records on a database

  - by Giorgio

  I have the following problem: I have a database containing more than 2 million records. Each record has a string field X and I want to display a list of records for which field X contains a certain string. Each record is about 500 bytes in size. To make it more concrete: in the GUI of my application I have a text field where I can enter a string. Above the text field I have a table displaying the (first N, e.g. 100) records that match the string in the text field. When I type or delete one character in the text field, the table content must be updated on the fly. I wonder if there is an efficient way of doing this using appropriate index structures and / or caching. As explained above, I only want to display the first N items that match the query. Therefore, for N small enough, it should not be a big issue loading the matching items from the database. Besides, caching items in main memory can make retrieval faster. I think the main problem is how to find the matching items quickly, given the pattern string. Can I rely on some DBMS facilities, or do I have to build some in-memory index myself? Any ideas? EDIT I have run a first experiment. I have split the records into different text files (at most 200 records per file) and put the files in different directories (I used the content of one data field to determine the directory tree). I end up with about 50000 files in about 40000 directories. I have then run Lucene to index the files. Searching for a string with the Lucene demo program is pretty fast. Splitting and indexing took a few minutes: this is totally acceptable for me because it is a static data set that I want to query. The next step is to integrate Lucene in the main program and use the hits returned by Lucene to load the relevant records into main memory.

• How do I change HOMEDRIVE HOMEPATH and HOMESHARE in Windows XP?

  - by user26034

  I have got a laptop which is configured to have the user profile in a network drive. This is causing me a lot of headaches since the connectivity to my company is very slow. I want to relocate the profile of my user into a local directory. How do I do that? Those are the settings at the moment: C:\>set HOME HOMEDRIVE=P: HOMEPATH=\ HOMESHARE=\\SOMESERVER\_myuser$ The drive P is a network drive mapped to HOMESHARE. I can't find where windows is setting those environment variables, not even in the registry. The laptop is running Windows XP.

• Apache reverse proxy setup

  - by nixnotwin

  I have a jboss application server on machine1. The application address is http://ip-address:8080/webapp. I wanted to have only an ip pointing to the application. So on machine2 I setup an apache proxy. But it only helps to shift to port 80 but the directory webapp cannot be removed. So using proxy, the address is http://ip-address/webapp. So is there a way to just have the ip point to the application. For example the address http://ip-address should open the web page of the application.

• group write permission ignored in ubuntu

  - by NorthPole

  Its probably my stupidy here but i'm stuck on this and would appreciate the help. I want my user to have full access to the local apache root folder, and i also want the apache to have full access to the same folder. What i did was create a new group called DevGroup and i added my username and www-data there. also i changed the permissions to 770 to allow full group access but now it wont allow me or the apache any kind of access to the folder. here is what i get with ls drwxrwx--- 12 root DevGroup 4096 Sep 27 17:34 testFolder which seems perfect but when i try as a user to access the file i get this var/www$ ls testFolder/ ls: cannot open directory testFolder/: Permission denied also when i try to access the a page in the folder from browser [Thu Sep 27 17:47:16 2012] [error] [client 127.0.0.1] PHP Fatal error: Unknown: Failed opening required '/var/www/testFolder/foo.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0

• How can I have sound output before logging in?

  - by ??O?????

  I have a machine (Ubuntu 11.10) that I would like to have it play audio (typically through an amplifier), but the machine should be headless (where its final placement will be). I will control what is played through ssh. However, there is no sound output until I login to the graphical console. At first I thought it was an issue with pulseaudio, so I promptly removed it to use the default ALSA, but I have the same issues. I ssh to the machine, I run alsamixer and get the typical cannot open mixer: No such file or directory error (while /proc/asound/cards display correctly what I have). If I login on the graphical console, alsamixer works fine in the ssh session, and I have sound output. I logout, and then alsamixer stops working. So something runs (Xsession perhaps?) when I login that enables sound output, and gets disabled when I logout. I remember in older versions of Ubuntu, there was a drum roll when the machine showed the login screen; that is not the case anymore. Perhaps if I somehow can enable that drum roll, I'll have fixed my problem too. In any case, the question I ask is what the title says.

• Location-Based redirection and duplication in sub-directories affecting SEO

  - by Joshua

  I currently own the website www.xyz.com. The website has a sub-directory for each of the 3 target countries: .../en-US/ (United States), .../es-MX/ (Mexico), and .../es-DO/ (Dominican Republic). I have two main questions about this setup: Currently, the main domain/root (xyz.com) contains a blank index.php file, but I would like for a user to be redirected to one of the sub-directories based on their regional location. What is the best way to accomplish this? I have looked at using browser language-based redirection, but how would I know whether to direct a user to the MX or DO site if the browser language is set to spanish? Is there a way to detect a user's geographic location? Also, the 3 websites are practically identical except they all have 3 unique color schemes and the US site is in english while the MX and DO sites are in spanish. My problem is that I believe GoogleBot is penalizing/banning my site because the spanish text on the MX and DO pages are nearly identical and are thus marked as duplicates/spam. Is there a way to avoid this?

• Wierd Windows File Share Behavior

  - by CT

  Scratching my head awhile on this. I'm on a Vista client trying to access a file share running on a Windows Server 2008 R2 box. Windows Active Directory Domain. The shares I am trying to access: \\Server1\FileShare1\Folder1\foo and \\Server1\FileShare1\Folder1\bar The client does not have any permissions at Folder1. The client has read permissions at folders foo and bar. In this example I can access \Server1\FileShare1\Folder1\foo but I get the following error when I try to access \Server1\FileShare1\Folder1\bar: "Network Error: Windows cannot access \Server1\FileShare1\Folder1\bar. Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click Diagnose" I hit Diagnose. It returns with "Windows checked the path and '\Server1\FileShare1' is correct but 'Folder1' could not be found." What is going on? It finds Folder1 fine when going to \Server1\FileShare1\Folder1\foo.

• Is there a piece of software which lets you turn "anything" into a dynamic reorderable list?

  - by Robin Green

  I could write this myself, but I want to know if it already exists. Basically, it must fulfill these criteria: To reorder items, the user must never have to manually renumber them. That would be annoying, and it doesn't scale. Can read from a range of data sources (e.g. a database, a directory on the file system, a text file, another list) When the original data source changes, the list must automatically change with it (possibly with confirmation, e.g. if a list item would be deleted) Ability to persist the list ordering in some fashion Graphical display of list items (so that they can include e.g. images) Optional extras: Ability to modify data and write back to the data source (other than the ordering information)

• Nginx PHP-FPM Basic Auth

  - by Lari13

  I have nginx with php-fpm installed on Debian Squeeze. Directory tree is: /var/www/mysite index.php secret_folder_1 admin.php static.html secret_folder_2 admin.php static.html pictures img01.jpg I need to close secret_folder_1 and secret_folder_2 with basic_auth. Now config looks like: location ~ /secret_folder_1/.+\.php$ { root /var/www/mysite/; fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME /var/www/mysite$fastcgi_script_name; include fastcgi_params; auth_basic "Restricted Access"; auth_basic_user_file /path/to/.passwd; } location ~ /secret_folder_1/.* { root /var/www/mysite/; auth_basic "Restricted Access"; auth_basic_user_file /path/to/.passwd; } Same config for secret_folder_2. Is it normal? I mean, first location for serving php files in restricted folder, and second location for serving static files. Can it be simplified?

• Installing datacommons from sunlight

  - by Newben

  I know strictly nothing from python and I am installing datacommons from the sunlightlabs. So I followed step by step the README.md https://github.com/sunlightlabs/datacommons First, it is said in the doc to add to the virtualenv dc_data, dc_matcchbox but I didn't find them. But I went to the final step to run ./manage.py runserver so I had the following message : (datacommons)newben@newben-VirtualBox:~/share-ubuntu/sunlightlabs-datacommons-e3ff1a3$ ./manage.py runserver fatal: Not a git repository (or any parent up to mount parent /home/mbenchoufi) Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set). Error: Can't find the file 'settings.py' in the directory containing './manage.py'. It appears you've customized things. You'll have to run django-admin.py, passing it your settings module. (If the file settings.py does indeed exist, it's causing an ImportError somehow.) In the 'sunlightlabs-datacommons-e3ff1a3' folder, I downloaded and put the files from github. By the way I didin't understand how to deal with the settings file. Could someone help me understand how to install datacommons ?

• Postfix not delivering mails

  - by Sotocan

  I have problems with a recently configured postfix MTA. When postfix starts the following warning appears: "postfix/qmgr[5078]: warning: connect to transport private/filter: No such file or directory" I have amavis-new as a content-filter, but even if I comment-out the relevant line, the warning appears. As a result (I think), of the above, I get errors like below, for every virtual domain that I have: "postfix/error[5080]: 254851834107: to=, relay=none, delay=13082, delays=13082/0.01/0/0.01, dsn=4.3.0, status=deferred (mail transport unavailable)" The good news for me, is that somehow I managed to fix that (don't ask me how!!!!) The problem is that now I have 50 or so mails, that were affected by the aforementioned problem, in the mail-queue... If I "postqueue -f " I get the same style of error as before (mail transport unavailable)...however new mails are delivered to their final destination properly... Any suggestions? Kind regards. P.S. Local mail delivery from/to Unix and virtual users, was OK write from the beginning!

• Does nginx auth_basic work over HTTPS?

  - by monde_

  I've been trying to setup a password protected directory in a SSL website as follows: /etc/nginx/sites-available/default server { listen 443: ssl on; ssl_certificate /usr/certs/server.crt; ssl_certificate_key /usr/certs/server.key; server_name server1.example.com; root /var/www/example.com/htdocs/; index index.html; location /secure/ { auth_basic "Restricted"; auth_basic_user_file /var/www/example.com/.htpasswd; } } The problem is when I try to access the URL https://server1.example.com/secure/, I get a "404: Not Found" error page. My error.log shows the following error: 011/11/26 03:09:06 [error] 10913#0: *1 no user/password was provided for basic authentication, client: 192.168.0.24, server: server1.example.com, request: "GET /secure/ HTTP/1.1", host: "server1.example.com" However, I was able to setup password protected directories for a normal HTTP virtual host without any problems. Is it a problem with the config or something else?

• ASP Fails with 500 Error

  - by VinceM

  We have a server setup as an IIS box and have some static pages with a few asp pages that handle the form submissions. The asp is really vbscript that sends a CDO message. When moving these pages to the new server the form will not submit, it gives a 500 error and the following shows in Event Viewer: Error: The Template Persistent Cache initialization failed for Application Pool 'DefaultAppPool' because of the following error: Could not create a Disk Cache Sub-directory for the Application Pool. The data may have additional error codes.. I can't seem to find any info on this anywhere... I was thinking it may have something to do with the fact that we created this server from an image of another server. Thanks for your help in advance... Vince

• Setting up a domain with a dedicated server

  - by Andrew M

  I have a dedicated server with a bunch of stuff on it already. Basically, I am accessing it now with the free domain I got when I purchased the server (http://example.com/directory, etc). I also have a second domain I want to use with a specific subdirectory (http://exampletwo.com/ should basically work as if I were under http://example.com/two, but it should use the exampletwo domain. I would assume I would change the A record of the second domain to the IP of the server, but how do I make it work with a subdirectory? I have full DNS control of the second domain but it is purchased on from a different registrar than the dedicated server. EDIT: It is a CentOS 5 server running Plesk/Virtuozoo.

• is there a way to have VIM do incremental search on text files?

  - by Alex

  Is there a way to have VIM do incremental search on text files? Vim already does incremental search within the currently open file. Examples of programs that demonstrate the type of search I'm trying to accomplish are Notational Velocity for MacOS, Resop for windows or SimpleNote for the web. These apps do an instant or incremental search in the files of a specific directory and make it easy/fast to narrow down the file you are looking for or create a new file. I use both but would rather live in one editor.(that being VIM) Is there some plug in that would do this?

• Permission denied on network share

  - by Philipp

  i have a Windows 8 host system running a virtual(hyper-v) Debian6 client with an lamp environment. My development environment runs under Windows and I mapped the folder with my php files to a network drive so Apache has access to them.(mount.cifs //pc/share /var/share/) This far no problems - I see my app on windows in the browser. The problem is, I can't write stuff in php to the share folder - everytime i got a permission denied message in my error logs. For testing purpose i tried to change the directory permissions of /var/share with chmod -R 777 /var/share without success. Now Iam a little bit stumped.. has anyone an idea how to solve this?

• Ubuntu 11.10 won't let me login; it kicks me back to login screen

  - by zlyfire

  I was just copying files from my external HDD to my .wine directory, when I noticed the place where the launchers are (Unity desktop) was getting fuzzy and holding onto graphics from the things in the location prior(i have it autohide when a window covers it). I assumed it was just RAM problem, so I canceled the copying, since it wasn't actually important. The glitch remained, and so did another; very slow response time. The mouse moved just fine, but windows were waiting about a minute after I hit the x button to close or even switch active window. Once again, I blamed RAM (only have 2 GBs) so I restarted. Usually, it autologs me into my account, since I'm the only user, but this time it presented me with the login screen. I thought it odd, but tried to log in. A black screen with some text pops up (assuming terminal screen) for half a second then kicks me back to the login screen. I tried the guest account and no luck. I went into terminal (alt+ctrl+f1) and logged in and it worked. I deleted .Xauthority, made new account, and even rebooted quite a few times, all to no avail. Anyone have an idea?

• Prevent Nautilus from displaying thumbnails on a specific mount

  - by Zakhar

  I have written a filesystem over Fuse to access a remote pseudo-NAS (the French "Freebox V6", I'll soon publish it as GPL3... when it's a little bit more polished!). The NAS is connected to a home ADSL, thus data comes down at the upload speed of ADSL, which is at best 1Mbps. My mount works fine (read-only at the moment), but Nautilus sees the mountpoint (and all sub-directories) as a "local" filesystem and tries to make thumbnails. As I have a directory full of images, this is quite horrible, because Nautilus then opens ALL the images to try to display the thumbnail. I could switch the Nautilus preferences to "Never" for thumbnails, but then I'll loose thumbnails on my "real" local filesystem. So the question is: with the preference "Only for local filesystem", how can I instruct Nautilus that my mountpoint is in fact NOT a local mount so that it will stop trying to draw thumbnails on that specific mount, but continue "thumbnailing" on mounts that are really local? Edit note: the same things happens if you use "standard worldwide" mounts such as sshfs, davfs,... as long as you mount over a relatively slow network (ADSL) and have images/movies on your mounted tree.

• Prompt for user group when logging into OSX domain

  - by mattdwen

  When a user is a member of more than one group, when logging in to a 10.6 machine, it shows a prompt asking for what group to apply settings for. We're using the groups to mount different shares, e.g. Production and Accounts, based on user membership. Often, a user is a member of more than one group, and needs all the drives available. The Open Directory server is running 10.6 also. Is there a way to skip this prompt and apply settings for all groups. I can foresee that there may be conflicts between group settings, but perhaps a priority can be set too? Or is this totally the wrong way to go about this?

• How to choose my own filename format for subscribed podcast files?

  - by user14068

  I subscribe to several podcasts where the filenames of the downloaded mp3 files have no particular pattern to them. When I copy the directory of accumulated mp3 files into my mp3 player, the files play in alphabetical order. What I really want is to play the files chronologically by release date. I currently use iTunes on Windows XP to download the files. What I do now is manually rename the files, adding the date in YYYYMMDD format to the start of each filename so that an alphabetical listing of files will correspond to their chronological order when I listen to them later in PocketTunes on my Palm Centro. Is there some way to get the release date into the filename automatically? If so, I could automate or possibly skip the file renaming step. I would switch from iTunes to something else if that would solve my problem. The file creation time on my local disk isn't a reliable indicator because sometimes I download a few days worth of content at one time, and the files don't necessarily get downloaded in chronological order.

• NTFS Folder has no owner, no permissions, can't be deleted

  Hi, I have a folder a 2003 member server which can't be deleted. Nothing has any permissions (domain admin and running up a cmd prompt as "nt authority\system" using psexec) - always "access denied". When I do a dir /q, the owner shows as "...". I've tried takeown.exe on the folder and also it's parent. The bad folder always reports "access denied". Also tried to reset using icacls, same thing. Explorer permissons has no sharing & security options or tabs. It works fine for other folders, even in the same directory. Bit stumped to say the least. g.
