• Setting up remote filesystem access without root privileges

  - by Luke Massa

  OK here's the situation. I have a computer A with complete admin access, and computer B (actually an account I login to) with very limited access. I am trying to make it so I can access a device on computer A (an external harddrive) on B. If I had more access to B, I would just mount the device on B, but I can't do that. I can ssh both directions, so theoretically I can copy data both directions, so it should be possible. I think a NFS might be helpful for me, but from what I've looked at, they all require the client to at some point perform a "mount" operation, something my client can't do. Thoughts?

• Running screen without root

  - by digital

  Hi, I recently updated screen on my server and for some reason when logged in as a normal user I can no longer create a screen session. If I run sudo screen it works. It's probably a permissions error somewhere but I'm not where to find it. Any help would be greatly appreciated.

• permanently mount multiple directories from different disks under root [on hold]

  - by piotrek

  I have SSD and HDD. Some directories like /var /srv /tmp should be on hdd while /boot /usr /lib on ssd. But do I have to create separate partition for every single directory? i want to have 2 or so partitions. one for each disk and distribute directories as needed. is it possible? and how? i've heard about symlinks, mount --bind, mhddfs but: symlinks are treated differently by tools like cp so i'm not sure if it's safe to have main system directories symlinked i have no idea how can I use mount --bind or mhddfs in fstab

• Why is it possible to change the password of an admin user on linux?

  - by enum

  A few days ago, a friend of mine, wanted to show me that he can use my linux even if I don't tell him my password. He entered in GRUB, selected the recovery mode option. My first problem is that he already had access to my files (read only). He tried to do passwd but failed. Then he did some kind of remount (I guess that gave him write rights) and after that he was able to change my password. Why is this possible? I personally see it a security issue. Where I work there are several people that use linux and neither of them have a BIOS password set or some other kind of security wall.

• VLC Server Media root

  - by Geoff

  When I run vlc like: vlc -I http I open up users to browse my whole system directory structure. This is too much. For example at the page http://localhost:8080/vlm.html I can click Edit on the Input field, then click Browse. On the pop-up I can continue to click '..'. I want to open this server up so that I can access it remotely, but I do not want to expose my whole system directory structure. How can I restrict the browse functionality to a specific sub-tree?

• Ubuntu: Resize the root LVM(2?) partition

  - by user12259

  I have an Ubuntu virtual machine running in VirtualBox 2.2.4, and I created it on an 8gb virtual disk which is too small. So, I am trying to increase the size of the disk. So far, I have done this: Created a new larger virtual disk Added the 2nd disk to the machine Used CloneZilla to clone the first disk onto the 2nd disk Removed the first disk Booted up off the 2nd (larger disk) But now I'm still stuck with an 8gb partition on my new 100gb virtual disk. Whats the easiest path from here to having a 100gb partition? :) I gather GPart can resize partitions, but it doesn't seem to support LVM2 partitions, which mine seems to be. thx Alex

• Tab bar controller inside a navigation controller, or sharing a navigation root view

  - by Daniel Dickison

  I'm trying to implement a UI structured like in the Tweetie app, which behaves as so: the top-level view controller seems to be a navigation controller, whose root view is an "Accounts" table view. If you click on any account, it goes to the second level, which has a tab bar across the bottom. Each tab item shows a different list and lets you drill down further (the subsequent levels don't show the tab bar). So, this seems like the implementation hierarchy is: UINavigationController Accounts: UITableViewController UITabBarController Tweets: UITableViewController Detail view of a tweet/user/etc Replies: UITableViewController ... This seems to work[^1], but appears to be unsupported according to the SDK documentation for -pushViewController:animated: (emphasis added): viewController: The view controller that is pushed onto the stack. It cannot be an instance of tab bar controller. I would like to avoid private APIs and the like, but I'm not sure why this usage is explicitly prohibited even when it seems to work fine. Anyone know the reason? I've thought about putting the tab bar controller as the main controller, with each of the tabs containing separate navigation controllers. The problem with this is that each nav controller needs to share a single root view controller (namely the "Accounts" table in Tweetie) -- this doesn't seem to work: pushing the table controller to a second nav controller seems to remove it from the first. Not to mention all the book-keeping when selecting a different account would probably be a pain. How should I implement this the Right Way? [^1]: The tab bar controller needs to be subclassed so that the tab bar controller's navigation item at that level stays in sync with the selected tab's navigation item, and the individual tab's table controller's need to push their respective detail views to self.tabBarController.navigationController instead of self.navigationController.

• List the root contexts in LDAP

I use Apache Directory Server and Java: Hashtable<String, String> contextParams = new Hashtable<String, String>(); contextParams.put("java.naming.provider.url", "ldap://localhost:10389"); contextParams.put("java.naming.security.principal", "uid=admin,ou=system"); contextParams.put("java.naming.security.credentials", "secret"); contextParams.put("java.naming.security.authentication", "simple"); contextParams.put("java.naming.factory.initial", "com.sun.jndi.ldap.LdapCtxFactory"); DirContext dirContext = new InitialDirContext(contextParams); NamingEnumeration<NameClassPair> resultList; //Works resultList = dirContext.list("ou=system"); while (resultList.hasMore()) { NameClassPair result = resultList.next(); System.out.println(result.getName()); } //Does not work resultList = dirContext.list(""); while (resultList.hasMore()) { NameClassPair result = resultList.next(); System.out.println(result.getName()); } I can list the sub nodes of ou=system. But I cannot list the sub nodes of the actual root node. I would like to have this list just like Apache Directory Studio can:

• Environment variable in xcconfig won't expand in Settings.bundle/Root.plist

  - by AO

  I have defined my own environment variable in a .xcconfig file and based my configurations on that as described at http://www.silverchairsolutions.com/blog/2008/03/automating-cocoa-deployments-with-sparkle-and-xcode. My environment variable is indeed expanded in Info.plist but not in my Settings.bundle/Root.plist. Why won't it expand there? Root.plist looks like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Title</key> <string>${PRODUCT_NAME}</string> <key>PreferenceSpecifiers</key> <array> <dict> <key>DefaultValue</key> <string>${PRODUCT_NAME}</string> <key>Key</key> <string>version</string> <key>Title</key> <string>Version</string> <key>Type</key> <string>PSTitleValueSpecifier</string> </dict> <dict> <key>DefaultValue</key> <string></string> <key>Key</key> <string>atc</string> <key>Title</key> <string>ATC</string> <key>Type</key> <string>PSTitleValueSpecifier</string> </dict> </array>

• Java SAX ContentHandler to create new objects for every root node

  - by behrk2

  Hello everyone, I am using SAX to parse some XML. Let's say I have the following XML document: <queue> <element A> 1 </element A> <element B> 2 </element B> </queue> <queue> <element A> 1 </element A> <element B> 2 </element B> </queue> <queue> <element A> 1 </element A> <element B> 2 </element B> </queue> And I also have an Elements class: public static Elements { String element; public Elements() { } public void setElement(String element){ this.element = element; } public String getElement(){ return element; } } I am looking to write a ContentHandler that follows the following algorithm: Vector v; for every <queue> root node { Element element = new Element(); for every <element> child node{ element.setElement(value of current element); } v.addElement(element); } So, I want to create a bunch of Element objects and add each to a vector...with each Element object containing its own String values (from the child nodes found within the root nodes. I know how to parse out the elements and all of those details, but can someone show me a sample of how to structure my ContentHandler to allow for the above algorithm? Thanks!

• PHP get "Application Root" in Xampp on Windows correctly

  - by Michael Mao

  Hi all: I found this thread on StackOverflow about how to get the "Application Root" from inside my web app. However, most of the approaches suggested in that thread can hardly be applied to my Xampp on Windows. Say, I've got a "common.php" which stays inside my web app's app directory: / /app/common.php /protected/index.php In my common.php, what I've got is like this: define('DOCROOT', $_SERVER['DOCUMENT_ROOT']); define('ABSPATH', dirname(__FILE__)); define('COMMONSCRIPT', $_SERVER['PHP_SELF']); After I required the common.php inside the /protected/index.php, I found this: C:/xampp/htdocs //<== echo DOCROOT; C:\xampp\htdocs\comic\app //<== echo ABSPATH /comic/protected/index.php //<== echo COMMONSCRIPT So the most troublesome part is the path delimiters are not universal, plus, it seems all superglobals from the $_SERVER[] asso array, such as $_SERVER['PHP_SELF'], are relative to the "caller" script, not the "callee" script. It seems that I can only rely on dirname(__FILE__) to make sure this always returns an absolute path to the common.php file. I can certainly parse the returning values from DOCROOT and ABSPATH and then calculate the correct "application root". For instance, I can compare the parts after htdocs and substitute all backslashes with slashes to get a unix-like path I wonder is this the right way to handle this? What if I deploy my web app on a LAMP environment? would this environment-dependent approach bomb me out? I have used some PHP frameworks such as CakePHP and CodeIgniter, to be frank, They just work on either LAMP or WAMP, but I am not sure how they approached such a elegant solution. Many thanks in advance for all the hints and suggestions.

• Getting content from PHP: Trouble with POST and query.

  - by vgm64

  Apologies for my longest question on SO ever. I'm trying to interface with a php frontend for a mysql database in ROOT (a CERN framework in C++ for high energy physics analysis). To start off with, I tried to get this php interface to play nice with wget and curl first because I'm more familiar with them. The following command works: wget --post-data "hostname=localhost:3306&un=joeuser&pw=psswd&myquery=show_spazio_databases;" http://some.host.edu/log/log_query_matlab.php The results are: database1 database2 That's good. If I leave out the --post-data then I get the result: Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'admin'@'localhost' (using password: NO) in /log/log_query_matlab.php on line 6 i'm dead! Access denied for user 'admin'@'localhost' (using password: NO) Warning: mysql_query() [function.mysql-query]: Access denied for user 'admin'@'localhost' (using password: NO) in /log/log_query_matlab.php on line 29 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /log/log_query_matlab.php on line 29 I have access to the php script (read only), but the error itself isn't too important. What matters it that using ROOT, I use a function called as socket.SendRaw(message, message.Length()) (socket is a TSocket) and this gives me the same "error" as wget without the post data switch if my "message" is "POST http://some.host.edu/log/log_query_matlab.php?hostname=localhost:3306&un=joeuser&pw=psswd&myquery=show_spazio_databases" This may be in vain, but does someone knows a way I should format the "message" that includes something that is equivalent to the --post-data switch. Or, is there a standard way to format POST requests in a single line (I've seen multi-line stuff. Is that right?) Sorry I'm clueless! PS. The mysql query is show databases but the space has been replaced with _spazio_, Italian for space. The author of the db and php interface requires it (and various replacements for symbols), but has anyone seen this before? Trying to troubleshoot that was terrible!

• Apache mod_rewrite - forward domain root to subdirectory

  - by DuFace

  I have what I originally assumed to be a simple problem. I am using shared hosting for my website (so I don't have access to the Apache configuration) and have only been given a single folder to store all my content in. This is all well and good but it means that all my subdomains must have their virtual document root's inside public_html, meaning they effectively become a folder on my main domain. What I'd like to do is organise my public_html something like this: public_html/ www/ index.php ... sub1/ index.php ... some_library/ ... This way, all my web content is still in public_html but only a small fraction of it will be served to the client. I can easily achieve this for all the subdomains, but it's the primary domain that I'm having issues with. I created a .htaccess file in public_html with the following: Options +SymLinksIfOwnerMatch # I'm not allowed to use FollowSymLinks RewriteEngine on RewriteBase / RewriteCond %{REQUEST_URI} !^/www [NC] RewriteRule ^(.*)$ /www/$1 [L] This works fairly well, but for some strange reason www.example.com/stuff is translated into a request for www.example.com/www/stuff and hence a 404 error is given. It was my understanding that unless an 'R' flag was specified, mod_rewrite was purely internal so I can't understand why the request is generated as that implies (to me at least) redirection. I assumed this would be a trivial problem to solve as all I actually want to do is forward all requests for the root of www.example.com to a subdirectory, but I've spent hours searching for answers and none are quite correct. I find it difficult to believe I'm the only person to have this issue. I apologise if this question has been answered on here before, I did search and trawl but couldn't find an appropriate answer. Please could someone shed some light on this?

• How to detect the root recursive call?

  - by ahmadabdolkader

  Say we're writing a simple recursive function fib(n) that calculates the nth Fibonacci number. Now, we want the function to print that nth number. As the same function is being called repeatedly, there has to be a condition that allows only the root call to print. The question is: how to write this condition without passing any additional arguments, or using global/static variables. So, we're dealing with something like this: int fib(int n) { if(n <= 0) return 0; int fn = 1; if(n > 2) fn = fib(n-2) + fib(n-1); if(???) cout << fn << endl; return fn; } int main() { fib(5); return 0; } I thought that the root call differs from all children by returning to a different caller, namely the main method in this example. I wanted to know whether it is possible to use this property to write the condition and how. Update: please note that this is a contrived example that only serves to present the idea. This should be clear from the tags. I'm not looking for standard solutions. Thanks.

• XML to JSON - losing root node

  I'm using net.sf.json with a Java project and it works great. The conversion of this XML: <?xml version="1.0" encoding="UTF-8"?> <important-data certified="true" processed="true"> <timestamp>232423423423</timestamp> <authors> <author> <firstName>Tim</firstName> <lastName>Leary</lastName> </author> </authors> <title>Flashbacks</title> <shippingWeight>1.4 pounds</shippingWeight> <isbn>978-0874778700</isbn> </important-data> converts to this in JSON: { "@certified": "true", "@processed": "true", "timestamp": "232423423423", "authors": [ { "firstName": "Tim", "lastName": "Leary" }], "title": "Flashbacks", "shippingWeight": "1.4 pounds", "isbn": "978-0874778700" } However, the root tag <important-data> is lost in the conversion. Being new to XML and JSON, I am not sure if this is suppose to be the correct behaviour. If not, is there any way to tell net.sf.json to convert it while keeping the root node property? Thanks.

• Trying to move files with specific file names from root directory to a subfolder

  - by Justin Reagan

  Hi I'm still pretty new to powershell so I apologize if I ask something that extremely basic. I have a root directory on a tftp server that pulls down config files from routers and other equipment every night. The files are like this IPaddress_YYYYMMDD_TA5000. There is a limitation in the equipment where the files can't be set to move into the root directory on their own. What I want to do is make a powershell script that will only move the files with the TA5000 part in the filename to the sub directory and only keep the 5 most recent files. I looked but I couldn't seem to find what I would need to do to parse the file for that specific string. I already have the portion of the script to delete the files based on age that was simple. Any help on getting started would be appreciated. Edit: I forgot to post the code I was trying. Move-Item c:\tftptransferfiles c:\tftptransferfiles\sca | Where-Object {_.name -like "*TA5000*"} I keep getting a error saying that the item at C:\tftptransferfiles is in use.

• check if foler exists in the root jquery

  - by Dimal Chandrasiri

  I'm trying to load an image to a div background using the following file structure in the root. WebContent -- | zharaimages -- | [ItemID] -- | Image.jpg This is done by jQuery and the file structure is inside the root. The ItemID folder is dynamic and I have to check whether the path exists using jQuery and if the path is not valid, I should go to a default path to fetch the default image. How can I check the path is valid using jQuery. I'm hoping to this can be done without an ajax call. Can any one help me on a tutorial or an API I can use for this! UPDATE The files are on the server. The concept I have is that I have 100s of item elements & I want to load an image for each item element. The images are saved in the server ( a local host ) and the folder hierarchy is divided using the item ID as shown. What I want to do is check whether the image file exists before appending it to the background of the item element div. Is this possible. This is a web application developed using spring.

/lib/x86_64-linux-gnu/libz.so.1.2.3.4Connection to stageserver.dockphp.com closed. After some debugging, I was able to narrow it down to a few things. For some reason the sshd daemon is running as root:www-data (apache user) instead of root. My ftp connection works but ssh over terminal fails. I have no idea whether it is getting caused due to suPHP or not (because that is the only place where user permission's etc. change). I really need to narrow it down and fix it asap. Thanks a lot!
