  • HTTP(S) based file server

    - by Michael
    I've got a server running Ubuntu 10.04. I've already gotten openssh for ssh and sftp on it. I've been looking for a web-based (http, or preferably https) file server, perhaps a web-front-end to an (S)FTP server, that allows access to a specific folder, and also allows uploads. It requires user authentication, preferably using PAM. This web-based solution is for users that are not allowed to use FTP software / browser extension and don't have flash / java browser plugins within their corporate environments. So far I have looked into: Webmin: Includes a file manager, however it uses Java, and I'm looking for a plugin-free implementation. Apache2: I was able to set up https and PAM authentication, but the barebone implementation doesn't include file upload (as far as I'm aware of). HFS: Haven't tried it out because it is for Windows/wine only, and I don't want to run it under wine.

  • CSS style submit like href tag

    - by seth.vargo
    Hi all, I have a button class that I wrote in CSS. It essentially displays block, adds some styles, etc. Whenever I add the class to a tags, it works fine - the a tag spans the entire width of its container like display:block should do... However, when I add the button class to an input button, Chrome, Safari, and Firefox all add a margin-right: 3px... I've used the DOM inspector in both Chrome and Safari and NO WHERE should it be adding a extra 3px padding. I tried adding margin: 0 !important; and/or margin-right: 0 !important to my button class in my CSS, but the browser STILL renders a 3px right margin! Is this a known issue, and is there a CSS-based solution (i.e. not jQuery/javascript) CODE FOLLOWS: .button { position: relative; display: block; margin: 0; border: 1px solid #369; color: #fff; font-weight: bold; padding: 11px 20px; line-height: 18px; text-align: center; text-transform: uppercase; cursor: hand; cursor: pointer; }

  • Determining filetype of file in assets folder

    - by ChaimKut
    Question: How do you programmatically distinguish between directories and regular files in the assets folder? When using AssetManager to access files in the assets folder, it seems impossible to determine if a file is in fact a file or a directory. You get the list of files from the list method and then open the file using the open method. I thought perhaps using the openFd method to get the asset file descriptor (and then subsequently requesting the normal file descriptor) would provide me some information. But requesting the file descriptor for a directory results in an IOException (which makes sense since what would it mean for a directory to have a file descriptor...?). Currently I'm relying on that IOException (resulting from attemptng to open a directory in the assets folder) in order to determine if a file is in fact a directory. (Opening a regular file works just fine). This seems like a bad idea. Any other suggestions to distinguish between a file and a directory?

  • Unable to remove a file which have a name like a command argument

    - by Justin
    By inadvertance, I've created a file called -r into my home directory. Please don't ask me how and why, I don't recall. But the fact is that now I cannot get rid of it : rm -rf rm: missing operand Try 'rm --help' for more information. Other try : rm /-/r rm: cannot remove ‘/-/r’: No such file or directory Another one : rm \-r rm: missing operand Try 'rm --help' for more information. Is there a way to remove this file without deleting the whole directory ? Thanks.

    This code works properly in my localhost. I am using xampp 1.7.3. but when I put it in the live server it shows Possible file upload attack!. 'upload/' is the folder under 'public_html' folder on the server. I can upload files via other script in that directory. <?php $uploaddir = '/upload/';//I used C:/xampp/htdocs/upload/ in localhost. is it correct here? $uploadfile = $uploaddir . basename($_FILES['file_0']['name']); echo '<pre>'; if (move_uploaded_file($_FILES['file_0']['tmp_name'], $uploadfile)) { echo "File is valid, and was successfully uploaded.\\n"; } else { echo "Possible file upload attack!\\n"; } echo 'Here is some more debugging info:'; print_r($_FILES); print "</pre>"; ?>

  • How to make read-only file system writable?

    - by Tim
    I am not sure since when the filesystem on my digital audio player has been changed to be read-only. I cannot copy files into it or remove files on it. Are there some possible reasons for the player's file system to change the permission of its file system? I tried chmod: $ sudo chmod a+rw SGTL\ MSCN/ chomd: changing permissions of `SGTL MSCN/': Read-only file system where "SGTL MSCN" is the mounted point of the digital audio player. I was wondering how to make it writable? Thanks and regards!

  • Newbie needs to learn basic file management

    - by Leo in NJ
    I have been using Ubuntu for abut 2 weeks and and still frustrated by simple file operations. I want to find a file called 9.jpg. Every internal command 3-rd party program I have tried also gives me 99.jpg, 999.jpg, lovepotion number9.jpg and a zillion other similar ones. How do you search for an EXACT file name WITHOUT wildcards? This is only my most recent frustration. I'm obviously missing something basic. good tutorial anywhere?

  • how to change dolphin's select region of a file/folder (in detail view mode)

    - by Daniel
    Since nautilus has removed the dual pane. So I turn to dolphin. I am wondering how to change the default select behavior in detail view mode? Now to select a file/folder, my cursor has to hover over that file/folder and then the left click will take effect, but I much prefer the nautilus way, that is as long as your cursor is in the same row of that file/folder, left click picks up that item. This I think is more robust for user selection, it is faster. Any ideas how to achieve this in dolphin?

  • Segmentation fault on certain inputs and not others

    - by Brandon Schwandt
    Heres a function I wrote that has some debugging elements in it already. When i enter either a "y" or a "Y" as the input I get a segmentation fault during runtime. When I enter any other value the code runs. The seg fault kicks out after it scans and gives me the response but before the "scan worked" line is output. DOn't know why it would act like this only on these values. If anyone needs the function call I have that as well. query_user(char *response [10]) { printf("response after query call before clear=%s\n",response); strcpy(response,""); printf("response after clearing before scan=%s\n",response); printf("Enter another person into the line? y or n\n"); scanf("%s", response); printf("response after scan=%s\n",response); printf("scan worked"); } main() { char response [10]; strcpy(response,"y"); printf("response=%s\n",response); printf("When finished with program type \"done\" to exit\n"); while (strcmp(response,"done") != 0) { printf("response after while loop and before query call=%s\n",response); query_user(&response); } } output on error: response after query call before clear=y response after clearing before scan= Enter another person into the line? y or n y response after scan=y Segmentation Fault (core dumped) output on non-error: response after query call before clear=y response after clearing before scan= Enter another person into the line? y or n n response after scan=n scan worked Cycle number 0 (program continues to run outside this function)

  • XML cdata tgas being erased when there's input in Russian

    - by Uri
    Hello, I have a very strange problem which I will be very thankful if someone would help me with. I have a form that has a textarea whose content is later transferred to a page that has a line like this (using DOM with php to change data on an XML file): $dom-getElementsByTagName("page")-item($itemNum)-getElementsByTagName("lang")-item(1)-getElementsByTagName("text")-item(0)-firstChild-data=$_POST['rus0']; The XML file in question looks like this: The strange thing happens when I upload it to the server and try to input Russian text, in which case it erases the CDATA completely and results in And, weirdly, the thing works fine on my own server emulator (I'm using MAMP with php 5, the remote server also has php 5) - in my machine inputing Russian works fine. Any ideas what's going on in this?

  • InputManager ignores cut/copy/paste when initiated from menu

    - by Wallstreet Programmer
    I'm using the InputManager to check if changes to controls are done by user or code. This works fine, except when user uses the context menu for cut/copy/paste. If the user do ctrl+v in a textbox, InputManager correctly notices it. However, if the paste is done from the context menu of the textbox, the InputManager never fires the PreNotifyInput or PostNotifyInput events. Anyone knows why? Or how to detect that these user actions? Below is a working sample. The lower textblock never gets updated when user uses the cut/copy/paste menu in the above textbox since PreNotifyInput never fires. XAML: <Window x:Class="InputMgrDemo.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <StackPanel> <TextBox TextChanged="TextBox_TextChanged" /> <TextBlock Name="_text" /> </StackPanel> </Window> Code behind: using System.Windows; using System.Windows.Controls; using System.Windows.Input; namespace InputMgrDemo { public partial class Window1 : Window { public Window1() { InitializeComponent(); InputManager.Current.PreNotifyInput += ((sender, e) => _userInput = true); InputManager.Current.PostNotifyInput += ((sender, args) => _userInput = false); } private void TextBox_TextChanged(object sender, TextChangedEventArgs e) { if (_userInput) { _text.Text = (sender as TextBox).Text; } } private bool _userInput; } }

  • How to remove text from file icons ?

    - by Jesse
    I am fairly new to Ubuntu (Linux). I noticed when creating a .java file or .py gives me an icon, however when I start writing code it overrides the thumbnail into showing text. Is there a way to disable this silly feature ? When I installed Linux Mint on the VM I noticed I was able to accomplish this task by unchecking "Show text in icon". I know they use Namo as their file manager. I read this thread and it did not work. How to stop Nautilus from creating thumbnails of specific file types?

  • Enable 'mod_rewrite' Using .htaccess File On cPanel Shared Hosting Server

    - by zulhfreelancer
    I'm using cPanel to host my website. I need to enable 'mod_rewrite' on this Shared Hosting cPanel account to run my script. I've tried to Google the solutions high and low but did not find any luck yet. Those tutorials that I found only work well with VPS and some of them said that, only hosting provider can change and enable it. But, some of them said that, it can be done easily by editing the .htaccess file. My question: If I want to edit the .htaccess file, what should I include in that file? What the 'rules' and 'conditions' that should be included?

  • Write to text file using ArrayList

    - by Ugochukwutubelum Chiemenam
    The program is basically about reading from a text file, storing the current data into an ArrayList, then writing data (from user input) into the same text file. Kindly let me know where I am going wrong in this sub-part? The data inside the text file is as follows: abc t1 1900 xyz t2 1700 The compiler is showing an error at the line output.format("%s%s%s%n", public class justTesting { private Scanner input; private Formatter output; private ArrayList<Student> tk = new ArrayList<Student>(); public static void main(String[] args) { justTesting app = new justTesting(); app.create(); app.writeToFile(); } public void create() { Text entry = new Text(); Scanner input = new Scanner(System.in); System.out.printf("%s\n", "Please enter your name, ID, and year: "); while (input.hasNext()) { try { entry.setName(input.next()); entry.setTelNumber(input.next()); entry.setDOB(input.next()); for (int i = 0; i < tk.size(); i++) { output.format("%s%s%s%n", tk.get(i).getName(), tk.get(i) .getTelNumber(), tk.get(i).getDOB()); } } catch (FormatterClosedException fce) { System.err.println("Error writing to file."); return; } catch (NoSuchElementException nsee) { System.err.println("Invalid input. Try again: "); input.nextLine(); } System.out.printf("%s\n", "Please enter your name, ID, and year: "); } } public void writeToFile() { try { output = new Formatter("testing.txt"); } catch (SecurityException se) { System.err .println("You do not have write access permission to this file."); System.exit(1); } catch (FileNotFoundException fnfe) { System.err.println("Error opening or creating file."); System.exit(1); } } }

  • Split large file, have arbitrary start index number

    - by nEJC
    I do a lot of file manipulation on my system and in one particular batch job I end up with around 16 Gb file. I need to prepare this data into smaller chunks for another process. I split it into 10k lines per file and numeric index, padded to 5 digits split -a 5 -d -l 10000 large_input_file /out_path/out. This way I end up with files named out.00000 out.00001 ... The problem is that this way indexing always starts with 0. Is there a way to set it to arbitrary starting index? man reveals nothing ...

  • g++: Use ZIP files as input

    - by Notinlist
    We have the Boost library in our side. It consists of huge amount of files which are not changing ever and only a tiny portion of it is used. We swap the whole boost directory if we are changing versions. Currently we have the Boost sources in our SVN, file by file which makes the checkout operations very slow, especially on Windows. It would be nice if there were a notation / plugin to address C++ files inside ZIP files, something like: // @ZIPFS ASSIGN 'boost' 'boost.zip/boost' #include <boost/smart_ptr/shared_ptr.hpp> Are there any support for compiler hooks in g++? Are there any effort regarding ZIP support? Other ideas?

  • Is asking for control totals on a file an outdated means of verifying a file?

    - by CTKeane
    I'm in a new position where I need to process a flat files on a regular basis. The last time I did this was 5 or 6 years ago but as part of the file layout I received control totals. It gave me simplistic information on the file like the total number of records as well as sums of the important fields. This helped me during testing then also during production to verify the file arrived and has correct information. I have asked for similar data for this new project and have hit a wall of no. Is this no longer a standard practice? Is there a better way?

  • Mysterious different conversion to string[] of seemingly same input data

    - by Roman Kuzmin
    During investigation of some problem I found that the reason was unexpected different conversion to string[] of seemingly same input data. Namely, in the code below two commands both return the same two items File1.txt and File2.txt. But conversion to string[] gives different results, see the comments. Any ideas why is it? This might be a bug. If anybody also thinks so, I’ll submit it. But it would nice to understand what’s going on and avoid traps like that. # *** WARNING # *** Make sure you do not have anything in C:\TEMP\Test # *** The code creates C:\TEMP\Test with File1.txt, File2.txt # Make C:\TEMP\Test and two test files $null = mkdir C:\TEMP\Test -Force 1 | Set-Content C:\TEMP\Test\File1.txt 1 | Set-Content C:\TEMP\Test\File2.txt # This gets just file names [string[]](Get-ChildItem C:\TEMP\Test) # This gets full file paths [string[]](Get-ChildItem C:\TEMP\Test -Include *) # Output: # File1.txt # File2.txt # C:\TEMP\Test\File1.txt # C:\TEMP\Test\File2.txt

  • How do I update mysql database when posting form without using hidden inputs?

    - by user1322707
    I have a "members" table in mysql which has approximately 200 field names. Each user is given up to 7 website templates with 26 different values they can insert unique data into for each template. Each time they create a template, they post the form with the 26 associated values. These 26 field names are the same for each template, but are differentiated by an integer at the end, ie _1, _2, ... _7. In the form submitting the template, I have a variable called $pid_sum which is inserted at the end of each field name to identify which template they are creating. For instance: <form method='post' action='create.template.php'> <input type='hidden' name='address_1' value='address_1'> <input type='hidden' name='city_1' value='city_1'> <input type='hidden' name='state_1' value='state_1'> etc... <input type='hidden' name='address_1' value='address_2'> <input type='hidden' name='city_1' value='city_2'> <input type='hidden' name='state_1' value='state_2'> etc... <input type='hidden' name='address_2' value='address_3'> <input type='hidden' name='city_2' value='city_3'> <input type='hidden' name='state_2' value='state_3'> etc... <input type='hidden' name='address_2' value='address_4'> <input type='hidden' name='city_2' value='city_4'> <input type='hidden' name='state_2' value='state_4'> etc... <input type='hidden' name='address_2' value='address_5'> <input type='hidden' name='city_2' value='city_5'> <input type='hidden' name='state_2' value='state_5'> etc... <input type='hidden' name='address_2' value='address_6'> <input type='hidden' name='city_2' value='city_6'> <input type='hidden' name='state_2' value='state_6'> etc... <input type='hidden' name='address_2' value='address_7'> <input type='hidden' name='city_2' value='city_7'> <input type='hidden' name='state_2' value='state_7'> etc... // Visible form user fills out in creating their template ($pid_sum converts // into an integer 1-7, depending on what template they are filling out) <input type='' name='address_$pid_sum'> <input type='' name='city_$pid_sum'> <input type='' name='state_$pid_sum'> etc... <input type='submit' name='save_button' id='save_button' value='Save Settings'> <form> Each of these need updated in a hidden input tag with each form post, or the values in the database table (which aren't submitted with the form) get deleted. So I am forced to insert approximately 175 hidden input tags with every creation of 26 new values for one of the 7 templates. Is there a PHP function or command that would enable me to update all these values without inserting 175 hidden input tags within each form post? Here is the create.template.php file which the form action calls: <?php $q=new Cdb; $t->set_file("content", "create_template.html"); $q2=new CDB; $query="SELECT menu_category FROM menus WHERE link='create.template.ag.php'"; $q2->query($query); $toall=0; if ($q2->nf()<1) { $toall=1; } while ($q2->next_record()) { if ($q2->f('menu_category')=="main") { $toall=1; } } if ($toall==0) { get_logged_info(); $q2=new CDB; $query="SELECT id FROM menus WHERE link='create_template.php'"; $q2->query($query); $q2->next_record(); $query="SELECT membership_id FROM menu_permissions WHERE menu_item='".$q2->f("id")."'"; $q2->query($query); while ($q2->next_record()) { $permissions[]=$q2->f("membership_id"); } if (count($permissions)>0) { $error='<center><font color="red"><b>You do not have access to this area!<br><br>Upgrade your membership level!</b></font></center>'; foreach ($permissions as $value) { if ($value==$q->f("membership_id")) { $error=''; break; } } if ($error!="") { die("$error"); } } } $member_id=$q->f("id"); $pid=$q->f("pid"); $pid_sum = $pid +1; $first_name=$q->f("first_name"); $last_name=$q->f("last_name"); $email=$q->f("email"); echo " // THIS IS WHERE THE HTML FORM GOES "; replace_tags_t($q->f("id"), $t); ?>

  • which one consume less resources? opening text file or make an sql query,both a thousand times ?

    - by imin
    hi I've a php website which displays recipes www.trymasak.my, to be exact. The recipes being displayed at the index page is updated about once a day. To get the latest recipes, I just use a mysql query which is something like "select recipe_name, page_views, image from table order by last_updated". So if I got 10000 visitors a day, obviously the query would be made 10000 times a day. A friend told me a better way (in terms of reducing server load) is when I update the recipes, I just put in the latest recipe details (names,images etc) into a text file, and make my page instead of querying a same query for 10,000 times, just get the data from the text file. Is his suggestion really better? If yes, which is the best php command should I use to open, read and close the text file? thanks
