  • "Could not open connection to the host" error when trying to send email using telnet

    - by hima
    I need to send email from my ASP.NET application. For that I am using the following command from the command prompt to connect to the specific port on tk2smtp: telnet tk2smtp.msn.com 25 But it's showing the following error on the command prompt: Could not open connection to the host I installed a telnet client in my machine. Let me know if there are any other things to be configured for this.

  • VNC connection through machine with only SSH port open

    - by pufferfish
    I would like to make a VNC connection from home to a Windows machine at work. The Windows machine is not accessible from the outside, but there is a Linux box that does have port 22 open, so it would seem that this can be done. I suspect it's just a command that "forwards" connections to port 22 on the Linux machine to the Windows machine? Just can't find an example that does exactly this though Thanks in advance!

  • Notepad++ last open tag closing

    - by Raveren
    I am searching for a plugin or any other way for n++ to close the last open tag on demand (i.e. assigned to a shortcut key), not automatically. Sadly all I could find is tag auto-closing (in TextFX and XMLtools), where a tag closure is added when the user types the '' (like in <div>). Any suggestions?

  • Remove default "open with" setting.

    - by themaninthesuitcase
    I have managed to leave the make default option ticked when using the "open with" option in windows 7. I ideally want this removed so the OS can manage the file type as before. I can't find the menu to remove this anywhere, I'm sure it used to be in the folder options panel in XP. Thanks

  • Unable to set "always open with" checkbox

    - by bas
    Configuration: windows 8 (desktop) firefox (latest version) I've been trying to figure out how to enable the checkbox to "always open with ... application for file type", for quite a while without any luck. Can anybody explain to me how I can enable the checkbox (see red rectangle). It's in Dutch, but I hope you recognize the dialog. Tried so far: - default programs (control panel) - HKCU/Microsoft/.../FileExts: remove the UserChoice (but it was already removed, so no luck there either) Thanks a lot in advance

  • "Open resource" dialog in Notepad++?

    - by n1313
    I am happily using Notepad++ for a long time, but there is one thing that this editor lacks: an "Open resource" dialog, as in Eclipse, that allows opening of files in project folder (and subfolders) by their names. Is there anything like this in N++ world?

  • Server is sending SPAM but it's not an open relay

    - by alexandernst
    I have a problem with Dovecot + Postfix. My server is sending SPAM from the local user "dovecot", but my server is not configured as an open relay (mails can be sent without auth-ing only from localhost). Also, nobody except me, has SSH access to the server. How can I find what exactly is triggering all those SPAM mails? How can I get something like a backtrace that shows what exactly happened the moments before a SPAM email got in the queue of postfix? Regards

  • Sentiment analysis for twitter in python

    - by Ran
    I'm looking for an open source implementation, preferably in python, of Textual Sentiment Analysis (http://en.wikipedia.org/wiki/Sentiment_analysis). Is anyone familiar with such open source implementation I can use? I'm writing an application that searches twitter for some search term, say "youtube", and counts "happy" tweets vs. "sad" tweets. I'm using Google's appengine, so it's in python. I'd like to be able to classify the returned search results from twitter and I'd like to do that in python. I haven't been able to find such sentiment analyzer so far, specifically not in python. Are you familiar with such open source implementation I can use? Preferably this is already in python, but if not, hopefully I can translate it to python. Note, the texts I'm analyzing are VERY short, they are tweets. So ideally, this classifier is optimized for such short texts. BTW, twitter does support the ":)" and ":(" operators in search, which aim to do just this, but unfortunately, the classification provided by them isn't that great, so I figured I might give this a try myself. Thanks! BTW, an early demo is here and the code I have so far is here and I'd love to opensource it with any interested developer.

  • What can a company possibly gain by making Android phones hard to root?

    - by Chinmay Kanchi
    As someone who recently got a HTC Hero, I had to jump through several hoops to get root access on the phone to install custom firmware. Now, Android is open-source and fairly easy to build and hack on an emulator. It seems to be against the spirit of open-source to lock down a phone so you can't hack the phone itself. Now, often, there are understandable (though not always justifiable) reasons for locking a device down. For example, it might have proprietary software on it or you might want to retain control of the platform. However, Android by its open-source nature makes such concerns moot. Everyone and their dog has access to the userland code, and HTC is forced by the GPL to release kernel sources for each of their devices. So, I fail to see any motivation for alienating the hackers, when there is no possible benefit (in my mind) to be had from doing this. Any idea why a company would want to do this? Is it just short-sightedness or am I missing possible commercial implications of this?

  • How to avoid open-redirect vulnerability and safely redirect on successful login (HINT: ASP.NET MVC

    - by Brad B.
    Normally, when a site requires that you are logged in before you can access a certain page, you are taken to the login screen and after successfully authenticating yourself, you are redirected back to the originally requested page. This is great for usability - but without careful scrutiny, this feature can easily become an open redirect vulnerability. Sadly, for an example of this vulnerability, look no further than the default LogOn action provided by ASP.NET MVC 2: [HttpPost] public ActionResult LogOn(LogOnModel model, string returnUrl) { if (ModelState.IsValid) { if (MembershipService.ValidateUser(model.UserName, model.Password)) { FormsService.SignIn(model.UserName, model.RememberMe); if (!String.IsNullOrEmpty(returnUrl)) { return Redirect(returnUrl); // open redirect vulnerability HERE } else { return RedirectToAction("Index", "Home"); } } else { ModelState.AddModelError("", "User name or password incorrect..."); } } return View(model); } If a user is successfully authenticated, they are redirected to "returnUrl" (if it was provided via the login form submission). Here is a simple example attack (one of many, actually) that exploits this vulnerability: Attacker, pretending to be victim's bank, sends an email to victim containing a link, like this: http://www.mybank.com/logon?returnUrl=http://www.badsite.com Having been taught to verify the ENTIRE domain name (e.g., google.com = GOOD, google.com.as31x.example.com = BAD), the victim knows the link is OK - there isn't any tricky sub-domain phishing going on. The victim clicks the link, sees their actual familiar banking website and is asked to logon Victim logs on and is subsequently redirected to http://www.badsite.com which is made to look exactly like victim's bank's website, so victim doesn't know he is now on a different site. http://www.badsite.com says something like "We need to update our records - please type in some extremely personal information below: [ssn], [address], [phone number], etc." Victim, still thinking he is on his banking website, falls for the ploy and provides attacker with the information Any ideas on how to maintain this redirect-on-successful-login functionality yet avoid the open-redirect vulnerability? I'm leaning toward the option of splitting the "returnUrl" parameter into controller/action parts and use "RedirectToRouteResult" instead of simply "Redirect". Does this approach open any new vulnerabilities? Side note: I know this open-redirect may not seem to be a big deal compared to the likes of XSS and CSRF, but us developers are the only thing protecting our customers from the bad guys - anything we can do to make the bad guys' job harder is a win in my book. Thanks, Brad

  • TLS (STARTTLS) Failure After 10.6 Upgrade to Open Directory Master

While that appears enough for LDAPS, it appears that this is not enough for TLS. Comparing our 10.6 and 10.5 slapd.conf and slapd_macosxserver.conf configuration files yields no clues. Replacing our certificate (generated with a self-signed ca) with an Apple Server Admin generated self signed certificate results in no change in ldapsearch results.

  • Open-source and client-side IRC-Client

    - by user125197
    I'm administrating a homepage with an IRC-Webclient. At the moment, it uses a Java-client, modified to be SSL-compatible and compatible with whatever design I want to use. The usual PJIRC thing, with users wishes and concerns implemented (I'll give you SSL-PJIRC if you want - no problem. The login-script will be improved for IE6-support this weekend, means write the object tag if an old IE is found, that's it. Rest runs perfectly well). But still, the better user experience would be a client that only requires the user to enable JavaScript. So, before I go into rewriting and customizing a complete Java-IRC-solution, I'd like to ask some other people - after researching for half a year of time. The requirements are: a) Free hosting, no cgi-bin is acceptable. A lot of hosters also have CGI supported, but it doesn't allow IRC-access. So, seems you are limited to x10-hosting for CGI:IRC. b) Solution must be open source (not free as in free beer, but free as in free speech - I want to be able to read every line of the code). c) Hosting cannot be limited to Windows-hosting. Free operation systems (anything with Linux, BSD, whatever - I think you get what I mean) must be possible. d) No server-side technology. I'm limited to everything that runs client-side only. (Well, a Java-Applet does...). d) Solution must support SSL. e) The side must be able to move. Means, you register to a new free hoster, load your things up via FileZilla and the thing simply runs. No server-concerning implementations needed. f) Old browsers must be supported. From all my research, there are two ways a) Java-Applet b) Use HTML5-Websockets (it is impossible to use the JavaScript-library I found, as it depends on ActiveX - means, Windows hosting). b) means "you are going to enter very unstable content". I worked with HTML5 for month, and, well ... Though, HTML5 also is not suitable for older browsers (old browser support is an absolutely necessary requirement). PHP by the way is a server side solution ... so no line of PHP. My idea now was a Java Applet, and a fallback which again is embedded and proprietary, but only requieres JavaScript (wsirc or Mibbit are great here, whilst I prefer wsirc ... and zooming fonts that are plainly to small, but worse, cannot read the code). So my question is - with free hosting, not installation on server, plain upload - do you see and open source, complelety client-side, ssl-compatible way to use or write a client? This wouldn't be my first programming project, I'm not afraid of the code. If there was a way and I had to write it, even from scratch, I'd do. From all I know, there sadly is none. But maybe some experienced admin has an idea? Best Wishes, yetanotheruser Sry my English isn't perfect. It's enough for programming at least.

  • Word Macros Problem: MsgBox function appears to lock all open windows of word

    - by amby
    I have some Macros that run in Word. We are migrating to Office 2007. Problem: the MsgBox function appears to lock all open windows of word. Any Ideas on how to get around that? (It is a macro that walks a user through a bunch of prompts for information that they enter into user forms and or MsgBoxes.) The error says: The command cannot be completed because a dialog box is open. Click OK then close all open dialog boxes to continue. Is there any way to have each window of word act independently of each other? The problem is that the information is frequently cut and pasted from other open word documents, and this doesn't work as the MsgBox locks control of ALL windows of Word 2007. The macros are pretty simple, but if you want to see the code, I will certainly post it. Basically, the old version of office let you go between windows, while 2007, that we are migrating to does not. I have run all the updates I could find. Any help would be greatly appreciated.

  • How do I find out what process Id and thread id / name has a file open

    - by peter
    Hi All, I am using C# in an application and am having some problems with a file becoming locked. The piece of code does this, while (true) { Read a packet from a socket (with data in it to add to the file) Open a file Writes data to it Close a file } But in the process the file becomes locked. I don't really understand how, we are are definately catching and reporting exceptions so I don't see how the file doesn't get closed every time. My best guess is that something else is opening the file, but I want to prove it. Can someone please provide a piece of code to check whether the file is open and if so report what processid and threadid has the file open. For example if I had this code, StreamWriter streamWriter1 = new StreamWriter(@"c:\logs\test.txt"); streamWriter1.WriteLine("Test"); // code to check for locks?? StreamWriter streamWriter2 = new StreamWriter(@"c:\logs\test.txt"); streamWriter1.Close(); streamWriter2.Close(); That will throw an exception because the file is locked when we try and open it the second time. So where the comment is what could I put in there to report that the current app (process Id) and the current thread (thread Id) have the file locked? Thanks.

  • Python - Open default mail client using mailto, with multiple recipients

    - by victorhooi
    Hi, I'm attempting to write a Python function to send an email to a list of users, using the default installed mail client. I want to open the email client, and give the user the opportunity to edit the list of users or the email body. I did some searching, and according to here: http://www.sightspecific.com/~mosh/WWW_FAQ/multrec.html It's apparently against the RFC spec to put multiple comma-delimited recipients in a mailto link. However, that's the way everybody else seems to be doing it. What exactly is the modern stance on this? Anyhow, I found the following two sites: http://2ality.blogspot.com/2009/02/generate-emails-with-mailto-urls-and.html http://www.megasolutions.net/python/invoke-users-standard-mail-client-64348.aspx which seem to suggest solutions using urllib.parse (url.parse.quote for me), and webbrowser.open. I tried the sample code from the first link (2ality.blogspot.com), and that worked fine, and opened my default mail client. However, when I try to use the code in my own module, it seems to open up my default browser, for some weird reason. No funny text in the address bar, it just opens up the browser. The email_incorrect_phone_numbers() function is in the Employees class, which contains a dictionary (employee_dict) of Employee objects, which themselves have a number of employee attributes (sn, givenName, mail etc.). Full code is actually here (http://stackoverflow.com/questions/2963975/python-converting-csv-to-objects-code-design) from urllib.parse import quote import webbrowser .... def email_incorrect_phone_numbers(self): email_list = [] for employee in self.employee_dict.values(): if not PhoneNumberFormats.standard_format.search(employee.telephoneNumber): print(employee.telephoneNumber, employee.sn, employee.givenName, employee.mail) email_list.append(employee.mail) recipients = ', '.join(email_list) webbrowser.open("mailto:%s?subject=%s&body=%s" % (recipients, quote("testing"), quote('testing')) ) Any suggestions? Cheers, Victor

  • Open a new browser window from embeded Internet Explorer

    - by Buddy
    I am working on a Windows desktop app (C++) that has an embedded Internet Explorer page. I'm working on the html page that is displayed in the There is not a back button control, so one of the requests is that links clicked on in the page should open the link in a browser window. It can open the link in the users default browser or in IE. Is this possible? I realize that this is not possible because javascript is in a sandbox and cannot touch outside applications. I'm thinking there might be a way because it is using the IE. I have tried the two methods that have worked for me in the past. Using jquery, I've tried these two approaches, but neither work in the app. They both work fine in normal browsers. Using target="_blank" $( "a" ).attr( "target", "_blank" ); The other is using window.open: $( "a" ).click( function() { window.open( $( this ).attr( "href" ) ); } ); I'm afraid that writing windows desktop applications is outside my area of expertise, so I cannot give more information regarding that side of the issue.
