  • How to resolve user registration and activation email error in Django registration?

    - by user2476295
    So I was just trying to setup a basic user authentication in Django and downloaded a django registration app with templates. Now when I run the server at 127.0.0.1:8000/accounts/register/ I get a basic registration page, I fill in the details and when I click submit I get this error "NoReverseMatch at /accounts/register/" Error during template rendering In template Users/sudhasinha/mysite/mysite/registration/templates/registration/activation_email.txt, error at line 4 'url' requires a non-empty first argument. The syntax changed in Django 1.5, see the docs. 1 {% load i18n %} 2 {% trans "Activate account at" %} {{ site.name }}: 3 4 http://{{ site.domain }}{**% url registration_activate activation_key %**} 5 6 {% blocktrans %}Link is valid for {{ expiration_days }} days.{% endblocktrans %} 7 This is what my activation_email.txt looks like: {% load i18n %} {% trans "Activate account at" %} {{ site.name }}: http://{{ site.domain }}{% url registration_activate activation_key %} {% blocktrans %}Link is valid for {{ expiration_days }} days.{% endblocktrans %} And this is what my registration_form.html looks like: {% extends "base.html" %} {% load i18n %} {% block content %} <form method="post" action="."> {{ form.as_p }} <input type="submit" value="{% trans 'Submit' %}" /> </form> {% endblock %} I have very minimal experience with Django and would appreciate some help to resolve this error. My urls seem to be setup correctly but I will post it if needed. Also pardon my horrible formatting

  • How to start a marquee with JavaScript based on user input?

    - by APShredder
    Hello everybody. I am trying to use JavaScript to start a marquee when a user puts their name into a textbox and then clicks a button. I've got an idea as to how to do it, but my script never fully works. Any help is appreciated! Here's what I have so far: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script type="text/javascript"> function StartMarquee() { var text = document.getElementById(namebox); if (text != null) { document.write("<marquee behavior='scroll' direction='right'>Hello " + text + "!</marquee>"); } else { alert("Enter your name first!!!"); } } </script> </head> <body> <table style="margin:0px auto 0px auto;"> <tr><td>Enter your name!</td> <td><input type="text" id="namebox"/></td> <td><input type="button" value="Enter" onclick="StartMarquee()"/></td></tr> </table> </body> </html>

  • Is there a way to effect user defined data types in MySQL?

    - by Dancrumb
    I have a database which stores (among other things), the following pieces of information: Hardware IDs BIGINTs Storage Capacities BIGINTs Hardware Names VARCHARs World Wide Port Names VARCHARs I'd like to be able to capture a more refined definition of these datatypes. For instance, the hardware IDs have no numerical significance, so I don't care how they are formatted when displayed. The Storage Capacities, however, are cardinal numbers and, at a user's request, I'd like to present them with thousands and decimal separators, e.g. 123,456.789. Thus, I'd like to refine BIGINT into, say ID_NUMBER and CARDINAL. The same with Hardware Names, which are simple text and WWPNs, which are hexstrings, e.g. 24:68:AC:E0. Thus, I'd like to refine VARCHAR into ENGLISH_WORD and HEXSTRING. The specific datatypes I made up are just for illustrative purposes. I'd like to keep all this information in one place and I'm wondering if anybody knows of a good way to hold this all in my MySQL table definitions. I could use the Comment field of the table definition, but that smells fishy to me. One approach would be to define the data structure elsewhere and use that definition to generate my CREATE TABLEs, but that would be a major rework of the code that I currently have, so I'm looking for alternatives. Any suggestions? The application language in use is Perl, if that helps.

  • How to fix codesign when it says user cancelled the operation? (And I didn't)

    - by eipipuz
    I'm compiling an iPhone app meant to be Distributed. It's my first app so I followed the "iPhone Provisioning Profiles" instructions. Unfortunately it fails with this: CodeSign build/*_*_.app cd "/Users/videojuegos/Documents/*_*_" setenv IGNORE_CODESIGN_ALLOCATE_RADAR_7181968 /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /usr/bin/codesign -f -s "iPhone Distribution: ******" "--resource-rules=/Users/videojuegos/Documents/*_*_/build/*_*_.app/ResourceRules.plist" --entitlements "/Users/videojuegos/Documents/*_*_/build/Unity-iPhone.build/Distribution-iphoneos/Unity-iPhone.build/*_*_.xcent" "/Users/videojuegos/Documents/*_*_/build/*_*_.app" /Users/videojuegos/Documents/*_*_/build/*_*_.app: The operation was cancelled by the user.

  • php user authentication libraries / frameworks ... what are the options?

    - by es11
    I am using PHP and the codeigniter framework for a project I am working on, and require a user login/authentication system. For now I'd rather not use SSL (might be overkill and the fact that I am using shared hosting discourages this). I have considered using openID but decided that since my target audience is generally not technical, it might scare users away (not to mention that it requires mirroring of login information etc.). I know that I could write a hash based authentication (such as sha1) since there is no sensitive data being passed (I'd compare the level of sensitivity to that of stackoverflow). That being said, before making a custom solution, it would be nice to know if there are any good libraries or packages out there that you have used to provide semi-secure authentication? I am new to codeigniter, but something that integrates well with it would be preferable. Any ideas? (i'm open to criticism on my approach and open to suggestions as to why I might be crazy not to just use ssl). Thanks in advance. Update: I've looked into some of the suggestions. I am curious to try out zend-auth since it seems well supported and well built. Does anyone have experience with using zend-auth in codeigniter (is it too bulky?) and do you have a good reference on integrating it with CI? I do not need any complex authentication schemes..just a simple login/logout/password-management authorization system. Also, dx_auth seems interesting as well, however I am worried that it is too buggy. Has anybody else had success with this? I realized that I would also like to manage guest users (i.e. users that do not login/register) in a similar way to stackoverflow..so any suggestions that have this functionality would be great

  • facebook: why I can't send email from app to user?

    - by flybywire
    I can't send email to my app users, even though I have the permissions. I am working with the java library, although I don't think it is related to that. long uid = ...; Collection<Long> uids = new ArrayList<Long>(); uids.add(uid); FacebookXmlRestClient client = new FacebookXmlRestClient(api, secret); boolean sendEmailPerm = client.users_hasAppPermission(Permission.EMAIL,uid); System.out.println("Can send email: "+ sendEmailPerm); Collection<String> sent = client.notifications_sendTextEmail(uids, "subject", "body"); System.out.println("Succesfully sent email to: "+sent); sent = client.notifications_sendFbmlEmail(uids, "subject", "body"); System.out.println("Succesfully sent email to: "+sent); I am trying both with fbml and text email. I can also obtain the user's proxied_email property but when I send email to that address with my regular mail client is doesn't arrive. The output is: Can send email: true Succesfully sent email to: [] Succesfully sent email to: []

  • How can I force a jQuery faded-in user control to remain after click events?

    - by David
    I have a basic page to which I'm adding an uploader control based on Bulk Uploader at c-sharpcorner.com and the control is in a jQuery-faded div based on yesdegisn The Bulk Uploader has two server side event handlers for two buttons--Add and Remove. After clicking these buttons, the fade disappears and you're back to the basic page--if the user needs to add more files, this is not desirable. The ArrayList of files added to a ListBox is maintained, but I have to click the "fade-in" link (LinkButton id="lnkDocumentUpload") to display this window again. I also need the control to POST to UploadPost.aspx, and it doesn't work either. Clicking the upload button(<asp:Button ID="btnUpload" runat="server" />) has the same behavior described above--fade disappears, data is retained, and no POST. I've surrounded the control with <form id="frmUpload" action="~/UploadPost.aspx"> ... <asp:Button ID="btnUpload" runat="server" Text="Upload"/> </form> A LinkButton activates the fade in jQuery via $("#lnkDocumentUpload").click(function() { centerPopup(); loadPopup(); });

  • Handling user interface in a multi-threaded application (or being forced to have a UI-only main thre

    - by Patrick
    In my application, I have a 'logging' window, which shows all the logging, warnings, errors of the application. Last year my application was still single-threaded so this worked [quite] good. Now I am introducing multithreading. I quickly noticed that it's not a good idea to update the logging window from different threads. Reading some articles on keeping the UI in the main thread, I made a communication buffer, in which the other threads are adding their logging messages, and from which the main thread takes the messages and shows them in the logging window (this is done in the message loop). Now, in a part of my application, the memory usage increases dramatically, because the separate threads are generating lots of logging messages, and the main thread cannot empty the communication buffer quickly enough. After the while the memory decreases again (if the other threads have finished their work and the main thread gradually empties the communication buffer). I solved this problem by having a maximum size on the communication buffer, but then I run into a problem in the following situation: the main thread has to perform a complex action the main thread takes some parts of the action and let's separate threads execute this while the seperate threads are executing their logic, the main thread processes the results from the other threads and continues with its work if the other threads are finished Problem is that in this situation, if the other threads perform logging, there is no UI-message loop, and so the communication buffer is filled, but not emptied. I see two solutions in solving this problem: require the main thread to do regular polling of the communication buffer only performing user interface logic in the main thread (no other logic) I think the second solution seems the best, but this may not that easy to introduce in a big application (in my case it performs mathematical simulations). Are there any other solutions or tips? Or is one of the two proposed the best, easiest, most-pragmatic solution? Thanks, Patrick

  • Using ASP.NET SQL Membership Provider, how do I store my own per-user data?

    - by Gary McGill
    I'm using the ASP.NET SQL Membership Provider. So, there's an aspnet_Users table that has details of each of my users. (Actually, the aspnet_Membership table seems to contain most of the actual data). I now want to store some per-user information in my database, so I thought I'd just create a new table with a UserId (GUID) column and an FK relationship to aspnet_Users. However, I then discovered that I can't easily get access to the UserId since it's not exposed via the membership API. (I know I can access it via the ProviderUserKey, but it seems like the API is abstracting away the internal UserID in favor of the UserName, and I don't want to go too far against the grain). So, I thought I should instead put a LoweredUserName column in my table, and create an FK relationship to aspnet_Users using that. Bzzzt. Wrong again, because while there is a unique index in aspnet_Users that includes the LoweredUserName, it also includes the ApplicationId - so in order to create my FK relationship, I'd need to have an ApplicationId column in my table too. At first I thought: fine, I'm only dealing with a single application, so I'll just add such a column and give it a default value. Then I realised that the ApplicationId is a GUID, so it'd be a pain to do this. Not hard exactly, but until I roll out my DB I can't predict what the GUID is going to be. I feel like I'm missing something, or going about things the wrong way. What am I supposed to do?

  • Can I prevent a Linux user space pthread yielding in critical code?

    - by KermitG
    I am working on an user space app for an embedded Linux project using the 2.6.24.3 kernel. My app passes data between two file nodes by creating 2 pthreads that each sleep until a asynchronous IO operation completes at which point it wakes and runs a completion handler. The completion handlers need to keep track of how many transfers are pending and maintain a handful of linked lists that one thread will add to and the other will remove. // sleep here until events arrive or time out expires for(;;) { no_of_events = io_getevents(ctx, 1, num_events, events, &timeout); // Process each aio event that has completed or thrown an error for (i=0; i<no_of_events; i++) { // Get pointer to completion handler io_complete = (io_callback_t) events[i].data; // Get pointer to data object iocb = (struct iocb *) events[i].obj; // Call completion handler and pass it the data object io_complete(ctx, iocb, events[i].res, events[i].res2); } } My question is this... Is there a simple way I can prevent the currently active thread from yielding whilst it runs the completion handler rather than going down the mutex/spin lock route? Or failing that can Linux be configured to prevent yielding a pthread when a mutex/spin lock is held?

  • Problem with mouse event on a user control (wpf).

    - by csciguy
    All, I have a user control, defined as follows. <UserControl x:Class="IDOView.AnimatedCharacter" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:IDOView" mc:Ignorable="d" Background="Transparent" > <Image Name="displayImage" Height="Auto" Width="Auto" Stretch="Fill" IsHitTestVisible="True"/> The control is added to a main page twice, as follows. <local:customControl x:Name="A1" Height="259" Width="197" DisplayImage="circle.png" Canvas.Left="-279" Canvas.Top="-56" MouseLeftButtonUp="DoA1"> <local:customControl x:Name="A1" Height="259" Width="197" DisplayImage="square.png" Canvas.Left="-209" Canvas.Top="-56" MouseLeftButtonUp="DoA2"> Essentially, about half of the circle is behind the square. I need the square image in this case to pass through events to the circle behind it. The square has an element cut out of it (transparent). What is happening now is that the circle event only registers if I click on the region that is not covered by the square. Surely there has to be a way to bubble this event, or click-through?

  • How to test if a user has SELECTED a file to upload ?

    - by Tristan
    Hello, on a page, i have : if (!empty($_FILES['logo']['name'])) { $dossier = 'upload/'; $fichier = basename($_FILES['logo']['name']); $taille_maxi = 100000; $taille = filesize($_FILES['logo']['tmp_name']); $extensions = array('.png', '.jpg', '.jpeg'); $extension = strrchr($_FILES['logo']['name'], '.'); if(!in_array($extension, $extensions)) { $erreur = 'ERROR you must upload the right type'; } if($taille>$taille_maxi) { $erreur = 'too heavy'; } if(!empty($erreur)) { ....................... } The problem is, if the users wants to edit information WITHOUT uploading a LOGO, it raises an error : 'error you must upload the right type' So, if a user didn't put anything in the inputbox in order to upload it, i don't want to enter in these conditions test. i tested : if (!empty($_FILES['logo']['name']) and if (isset($_FILES['logo']['name']) but both doesn't seems to work. Any ideas? edit : maybe i wasn't so clear, i don't want to test if he uploaded a logo, i want to test IF he selected a file to upload, because right now, if he doesn't select a file to upload, php raises an error telling he must upload with the right format. thanks.

  • User will input some filter criteria -- how can I turn it into a regular expression for String.match

    - by envinyater
    I have a program where the user will enter a string such as PropertyA = "abc_*" and I need to have the asterisk match any character. In my code, I'm grabbing the property value and replacing PropertyA with the actual value. For instance, it could be abc_123. I also pull out the equality symbol into a variable. It should be able to cover this type of criteria PropertyB = 'cba' PropertyC != '*-this' valueFromHeader is the lefthand side and value is the righthand side. if (equality.equals("=")) { result = valueFromHeader.matches(value); } else if (equality.equals("!=")) { result = !valueFromHeader.matches(value); } EDIT: The existing code had this type of replacement for regular expressions final String ESC = "\\$1"; final String NON_ALPHA = "([^A-Za-z0-9@])"; final String WILD = "*"; final String WILD_RE_TEMP = "@"; final String WILD_RE = ".*"; value = value.replace(WILD, WILD_RE_TEMP); value = value.replaceAll(NON_ALPHA,ESC); value = value.replace(WILD_RE_TEMP, WILD_RE); It doesn't like the underscore here... abcSite_123 != abcSite_123 (evaluates to true) abcSite_123$1.matches("abcSite$1123") It doesn't like the underscore...

  • MediaWiki: how to hide users from the user list?

    - by Dave Everitt
    I've set up Mediawiki 1.15.1 for a client who has added two users by mistake. They now want to hide these users from the user list. It seems this is done via the $wgGroupPermissions array with $wgGroupPermissions['suppress']['hideuser'] = true;, but it isn't at all clear what entry this needs for the hiding to work, or whether a new group ('hidden' or whatever) has to be created first with $wgAddGroups['bureaucrat'] = true;. For now, I've added the two users to be hidden to the 'Oversight' group which explains 'Block a username, hiding it from the public (hideuser)', but they still appear on the Special:ListUsers page. At a loss as to how the MediWiki arrays alter options displayed in the interface, so far I've added this to LocalSettings.php: $wgGroupPermissions['suppress']['hideuser'] = true; $wgAddGroups['supress'] = true; Or - since they haven't actually added anything to the wiki - could they simply be removed from the MySQL users table - although MediaWiki warns against this? Has anyone else done this successfully? Update - this is a hole in MediaWiki admin (although there are workarounds). See this thread on MediaWIki Users and the note to the reply below.

  • How would I go about letting a user add and associate a comma separated list of categories while add

    - by Throlkim
    I've been struggling for quite a while to get this feature working: I want my user to be able to select categories when uploading a photograph, but additionally be able to specify a comma-separated list of categories to create/find and associate with the photograph. I've had this working by using an attr_accessor :new_categories on the photographs model, but having that there without the column existing breaks both Paperclip and Exifr. Obviously, image upload and EXIF data retrieval are pretty important for a photography website, but not being able to add categories while uploading a photograph is a pain in the arse. Methods I've tried so far: Using attr_accessor to add a field for new_categories. Breaks gems. Using an Ajax sub-form to add categories. Formtastic can't handle it. Adding a column for new_categories to the photograph model. It works, but it's horrific. I haven't tried using a nested form, but I'd need to intercept it and stop it from processing it as normal. Here's an example of what I'm trying to accomplish: http://imgur.com/rD0PC.png And the function I use to associate the categories: def process_new_categories unless self.new_categories.nil? for title in self.new_categories.split(",") self.categories << Category.find_or_create_by_title(title.strip.capitalize) end end end Has anyone got any ideas as to how to do this?

  • how to emulate thread local storage at user space in C++ ?

    - by vprajan
    I am working on a mobile platform over Nucleus RTOS. It uses Nucleus Threading system but it doesn't have support for explicit thread local storage i.e, TlsAlloc, TlsSetValue, TlsGetValue, TlsFree APIs. The platform doesn't have user space pthreads as well. I found that __thread storage modifier is present in most of the C++ compilers. But i don't know how to make it work for my kind of usage. How does __thread keyword can be mapped with explicit thread local storage? I read many articles but nothing is so clear for giving me the following basic information will __thread variable different for each thread ? How to write to that and read from it ? does each thread has exactly one copy of the variable ? following is the pthread based implementation: pthread_key_t m_key; struct Data : Noncopyable { Data(T* value, void* owner) : value(value), owner(owner) {} int* value; }; inline ThreadSpecific() { int error = pthread_key_create(&m_key, destroy); if (error) CRASH(); } inline ~ThreadSpecific() { pthread_key_delete(m_key); // Does not invoke destructor functions. } inline T* get() { Data* data = static_cast<Data*>(pthread_getspecific(m_key)); return data ? data->value : 0; } inline void set(T* ptr) { ASSERT(!get()); pthread_setspecific(m_key, new Data(ptr, this)); } How to make the above code use __thread way to set & get specific value ? where/when does the create & delete happen? If this is not possible, how to write custom pthread_setspecific, pthread_getspecific kind of APIs. I tried using a C++ global map and index it uniquely for each thread and retrieved data from it. But it didn't work well.

  • What's the best way to send user-inputted text via AJAX to Google App Engine?

    - by Cuga
    I'm developing in Google App Engine (python sdk) and I want to use jQuery to send an Ajax request to store an answer to a question. What is the best way to send this data to the server? Currently I have: function storeItem(question_id) { var answerInputControl = ".input_answer_"+question_id; var answer_text = $(answerInputControl).text(); $.ajax({ type: "POST", url: "store_answer.html", data: "question="+question_id, success: function(responseText){ alert("Retrieved: " + responseText); } }); } This takes a question Id and provides it to the server via the query string. But on the server-side, I'm unable to access the content of the answer control which I want to store. Without Ajax, I'm able to perform this operation with the following: class StoreAnswers(webapp.RequestHandler): def post(self): question_id = self.request.get("question_id") answer_text = self.request.get("input_answer" + question_id) But when doing this call through Ajax, my answer_text is empty. Do I need to send the contents of this control as part of the data with the Ajax request? Do I add the control itself to the query string? Its contents? Does it matter that the content might be a few hundred characters long? Is this the most-recommended practice? If sending it as a query string, what's the best way to escape the content so that a malicious user doesn't harm the system?

  • Can I save & store a user's submission in a way that proves that the data has not been altered, and that the timestamp is accurate?

    - by jt0dd
    There are many situations where the validity of the timestamp attached to a certain post (submission of information) might be invaluable for the post owner's legal usage. I'm not looking for a service to achieve this, as requested in this great question, but rather a method for the achievement of such a service. For the legal (in most any law system) authentication of text content and its submission time, the owner of the content would need to prove: that the timestamp itself has not been altered and was accurate to begin with. that the text content linked to the timestamp had not been altered I'd like to know how to achieve this via programming (not a language-specific solution, but rather the methodology behind the solution). Can a timestamp be validated to being accurate to the time that the content was really submitted? Can data be stored in a form that it can be read, but not written to, in a proven way? In other words, can I save & store a user's submission in a way that proves that the data has not been altered, and that the timestamp is accurate? I can't think of any programming method that would make this possible, but I am not the most experienced programmer out there. Based on MidnightLightning's answer to the question I cited, this sort of thing is being done. Clarification: I'm looking for a method (hashing, encryption, etc) that would allow an average guy like me to achieve the desired effect through programming. I'm interested in this subject for the purpose of Defensive Publication. I'd like to learn a method that allows an every-day programmer to pick up his computer, write a program, pass information through it, and say: I created this text at this moment in time, and I can prove it. This means the information should be protected from the programmer who writes the code as well. Perhaps a 3rd party API would be required. I'm ok with that.

  • I just received a complaint from a user of the website I maintain. Should I do anything?

    - by Chris
    I was sent sent a large wall of text from a user of the website I maintain at my job. They are clearly upset for having to deal with a horribly outdated web application that has not seen any serious updates in over 6+ years. No refactoring has been done, the code quality is terrible, the security unchecked, policy compliances ignored, in addition to being ugly and frankly embarrassing. Keep in mind this is a small business but the website is used by hundreds daily. I'm one of two programmers there, and I've been working there for two years. This person says they are about my age (22) and understand technology (but can't use proper grammar). The complaint mentioned awkward pages and actions on the website, but they don't even have a clue as to the depth of the flaws in this website. Now, I would love to honestly tell them that there's a lot wrong with this company and that this application was built when we were in high school. And that while it's not my fault that the website is terrible, I'm the one in position to fix it. But on the other hand, I could just say nothing and ignore it. Would doing this publicly have any advantage to future employees (showing integrity) or would it just be a completely pointless mistake? Odds are, even if I respond only that one person will ever read it. Regardless, I'm probably just going to ignore it and continue starting my project to refactor the website.

  • How do I apply an arcball (using quaternions) along with mouse events, to allow the user to look around the screen using the o3d webgl framework?

    - by Chris
    How do I apply an arcball (using quaternions) along with mouse events, to allow the user to look around the screen using the o3d webgl framework? This sample (http://code.google.com/p/o3d/source/browse/trunk/samples_webgl/o3d-webgl-samples/simpleviewer/simpleviewer.html?r=215) uses the arcball for rotating the transform of an "object", but rather than apply this to a transform, I would like to apply the rotation to the camera's target, to create a first person style ability to look around the scene, as if the camera is inside the centre of the arcball instead of rotating from the outside. The code that is used in this sample is var rotationQuat = g_aball.drag([e.x, e.y]); var rot_mat = g_quaternions.quaternionToRotation(rotationQuat); g_thisRot = g_math.matrix4.mul(g_lastRot, rot_mat); The code that I am using which doesn't work var rotationQuat = g_aball.drag([e.x, e.y]); var rot_mat = g_quaternions.quaternionToRotation(rotationQuat); g_thisRot = g_math.matrix4.mul(g_lastRot, rot_mat); var cameraRotationMatrix4 = g_math.matrix4.lookAt(g_eye, g_target, [g_up[0], g_up[1] * -1, g_up[2]]); var cameraRotation = g_math.matrix4.setUpper3x3(cameraRotationMatrix4,g_thisRot); g_target = g_math.addVector(cameraRotation, g_target); where am I going wrong? Thanks

  • Launching firefox on remote server causes local firefox to start instead

    - by terdon
    Right, this is strange. I am connecting from my laptop (LMDE) to a remote host (SUSE linux enterprise) using ssh -X. I want to launch a firefox instance running on the remote server so I can have access to webpages on a private network. User@RemoteMachine $ which -a firefox /usr/bin/firefox User@RemoteMachine $ /usr/bin/firefox --version Mozilla Firefox 2.0.0.2, Copyright (c) 1998 - 2007 mozilla.org User@LocalMachine $ which -a firefox /usr/bin/firefox User@LocalMachine $ /usr/bin/firefox --version Mozilla Firefox 14.0.1 Now, if firefox is not running on the local machine, everything goes as expected and executing firefox on the remote machine causes a firefox (v 2.0) window running on the remote machine to show up. However, if firefox is running on the local machine a second window of firefox 14.0.1 running on the local machine appears. I have checked top in both machines. In the 2nd case, a firefox process briefely appears on the remote machine and then disappears when the local version of firefox is launched. My questions are the following: What gives? How/why can firefox connect to its existing instance on the local machine? The remote machine appears to have access to the local machine. It, in fact, appears to have the right to execute programs on my local machine. Am I missing something or is this just weird? Is this not a security risk?
