  • Migrating to ssh key authentication; implications of adding sbin's to users $PATH

    - by ancillary
    I'm in the process of migrating to key's for authentication on my CentOS boxes. I have it all set up and working, but was a bit taken aback when I noticed service (and other things) didn't work the way I was accustomed to. Even after su'ing to root, still had to call the full path for it to work (which I assume to be expected/normal behavior). I also assume this is because there are different $PATH's for root (what I was using and am used to) and the newly created, key-using user. Specifically, I noticed the sbin's of the world missing from the user path. If I were to add those paths (/sbin/,/usr/sbin/,/usr/local/sbin) to a profile.d .sh script for this new key-loving user, would: I be opening up the system in ways I shouldn't be? I be doing something I needn't do save for reasons of laziness? I create other potential problems? Thanks.

  • jQuery $.data(): Possible misuse?

    - by Rosarch
    Perhaps I'm using $.data incorrectly. Assigning the data: var course_li = sprintf('<li class="draggable course">%s</li>', course["fields"]["name"]); $(course_li).data('pk', course['pk']); alert(course['pk']); // shows a correct value Moving the li to a different ul: function moveToTerm(item, term) { item.fadeOut(function() { item.appendTo(term).fadeIn(); }); } Trying to access the data later: $.each($(term).children(".course"), function(index, course) { var pk = $(course).data('pk'); // pk is undefined courses.push(pk); }); What am I doing wrong? I have confirmed that the course li on which I am setting the data is the same as the one on which I am looking for it. (Unless I'm messing that up by calling appendTo() on it?)

  • Forcing exact hostname match in IIS

    - by iis_newbie
    I am looking how to force an exact hostname match within IIS when using https. For instance, I want "https://works.mysite.com/resource" to be ok, but "https://noworks.mysite.com/resource" to return 404 (assuming they both resolve to the same IP). IIUC, the default behavior of IIS when going to "https://noworks.mysite.com/resource" is to get a cert warning, if the user presses continue, the user is able to access the URL. I was able to do this by generating a *.mysite.com SSL cert, and then specify the hostname within the bindings in IIS, but without the * in the beginning, the hostname field is disabled and blank. Am I missing something simple here?

  • Explicitly typing variables causes compiler to think an instance of a builtin type doesn't have a pr

    - by wallacoloo
    I narrowed the causes of an AS3 compiler error 1119 down to code that looks similar to this: var test_inst:Number = 2.953; trace(test_inst); trace(test_inst.constructor); I get the error "1119: Access of possibly undefined property constructor through a reference with static type Number." Now if I omit the variable's type, I don't get that error: var test_inst = 2.953; trace(test_inst); trace(test_inst.constructor); it produces the expected output: 2.953 [class Number] So what's the deal? I like explicitly typing variables, so is there any way to solve this error other than not providing the variable's type?

  • XML Architecture

    - by Roflcoptr
    For my application I have to use a undefined number of different detection strategies. A strategy is defined in the following fashion: The AND gate can also be a OR gate. For now, I hard coded all these rules in my code. For better extensability, I'd like to define all the detection startegies respectively rules in a XML file and parse it. But I'm not really sure how I can define such a detection strategy in a XML file. Any hints how to start?

  • JavaScript's Associative Array / Object can't be read in functions

    - by Matrym
    At the very beginning of the javascript file, I have: var lbp = {}; lbp.defaults = { minLength: 40 }; I can successfully alert it afterwards, with: alert(lbp.defaults.minLength); But as soon as I put it inside a function, when I alert, I get "Undefined". What gives, and how do I avoid this? Is it absolutely necessary to pass this variable into each function, for example, by doing: function(lbp) { alert(lbp.defaults.minLength); } I would have thought that defining it first, it would attain global scope and not be required to be passed in? Thanks in advance for enlightening me :)

  • Mocha expects method

    - by Masha
    So my situation is: I have a 2 modules that have the same structure like that: module Module1 class Config def fee_rate 2 end end end So, say, Module2 would have class Config with the method fee_rate, just with a different value (those are actually implemented in a rails engine, but it shouldn't matter) and then my model can use either Module1 or Module2 to get the fee rate value like that: def config @config ||= "#{module_name.titleize}::Config".constantize.new @config end def get_value config.get_fee * some_other_value end What I'm trying to test is if get_fee function was called on the correct class: "#{model.module_name.titleize}::Config".constantize.any_instance.expects(:get_fee).at_least_once model.get_value and on the line when I call get_value I get the following error - undefined method `*' for nil:NilClass. I'm completely lost now, so I'd appreciate any help and ideas.

  • OS X SnowLeopard menubar icons appear/disappear in 8 second cycle

    - by Robot
    I just bought a new Mac Mini, and used Migration Assistant to move a user from an iMac to it. All went well, except a very strange behavior... the default OS X menubar icons like time, spotlight, etc (but NOT user installed app icons like dropbox or xmarks) appear and disappear in a very regular 8 second cycle. They appear for about 2 seconds, and then disappear for about 6. This is a screenshot with the icons, and this is a screenshot without them. This is very annoying and I have not found anything online with similar symptoms. Any ideas?

  • Is running multiple databases on login going to make my Mac really slow?

    - by Walrus the Cat
    Sometime ago, I installed Postgres, and the Launch agent that causes it to run when I log in. Just now, I did the same thing for Mongo. I was just about to do it for Couch. I don't remember if I ever did it for MySQL, but I probably did. Mongo and Couch are just 'when I have time to look into it' sort of things, but I don't want to have to remember to start them when I do. I have a 2.4 Ghz processor and 8 GB ram. Is this sort of behavior going to significantly impact my computer's performance? Should I be scrambling to uninstall all but the database I'm currently using, or can I install all the things and run them all the time? Thanks

  • Audio Midi Setup needs to be quit before able to be opened again in OS X Mountain Lion

    - by Dschee
    Since Mac OS X Lion (I'm using Mac OS 10.8.2 now) I have the exact same issue with audio midi setup software from Apple. It's not really a not working thing but it still is annoying: Every time I open audio midi setup to change something (e.g. change to my Apple TV for audio playback) and close the window afterwards the application doesn't quit – what would be OK if a click on the Icon (or the starting of the application over Spotlight) would cause the application to open a new window of audio midi setup, but it doesn't. So what I have to do to get the window back is first quitting the application manually and restarting it again. That's quite painful since I sometimes opened the application days ago and forgot that it's still opened... Does anyone have the same issue? Can someone explain this behavior to me? And most important: Does anyone know a workaround?

  • preg_match not defined in php4 in openwrt?

    - by user2723949
    I have installed the packages PHP4 and PHP4-CGI in openwrt through command line (opkg install) when I tried this simple code by putting this in the openwrt www folder, <?php $subject = "abcdef"; $pattern = '/^def/'; preg_match($pattern, $subject, $matches, PREG_OFFSET_CAPTURE, 3); print_r($matches); ?> I got this error Fatal error: Call to undefined function: preg_match() in /www/phptest.php on line 4 but php manual says preg_match() is defined in php4 also.. What might be the reason for this error? Is there any other PHP module that is to be installed? Or is there any alternate method for preg_match?

  • Partition falsly recognized as RAW

    - by Paul Hiemstra
    On my 2 TB data disk I have two primary partitions, one of 1.6 TB for data storage in Linux (ext3) and one of 300 GB for some additional data storage for Windows. I run a dual-boot Windows 7/Ubuntu 12.04 install. The issue I have that if I start my computer into Windows 7, bot the partitions on my 2TB data drive are not recognized. In stead, Windows 7 sees one 1TB partition with type RAW. However, if I reboot to Linux, and then back to Windows 7, the partitions are correctly recognized. The following two screenshots illustrate my situation. Before I reboot to linux: and after the reboot: I have two questions: What could cause this behavior? How can I solve this issue.

  • Citrix Mixed Server Session problems

    - by oldskool
    Hello, we've run an Citrix Farm with 4 x Windows 2008 x64 (XenApp 5.0 FP3) and one server Win 2003 x86 (Xenapp 4.6). Yesterday we had a strange problem with Session logins. Existing Sessions could work without problems but new logins were not possible. In the AMC we could not see the Sessions on the Servers. After an reboot all worked fine again. We run the 32 Bit Server since 3 days in our farm (for one Application). Could it be possible that this behavior is caused of the mixed farm? -- (we got in this time a lot of wmi warnings that the Provider CitrixEvemtProv has been registered but it does not correctly impersonate user requests.

  • Preprocess outgoing email bodies with a linux smtp server/proxy?

    - by jdc0589
    I have an smtp server running locally on my server, and need to edit the contents of email bodies before they actually get sent out. I have tried using EmailRelay to proxy my smtp server with the --filter option to specify a filter/editing executable, but am getting some odd behavior. Currently, I specify an executable shell script as the filter program and all it is supposed to do is append some text to a log file and return 0 so I know it actually got called. The weird thing is the email gets sent but nothing shows up in my log file like it should (but it does when I run the script manualy). If I remove the 'exit 0' statement, the email does not send like I would expect. Are there any other options/suggestions?

  • Client PC not booting when certain TFT plugged in - TFT or graphics card failure?

    - by Chake
    here comes something quite strange: On a client machine (DELL Vostro 420) we experienced problems when booting: when turning on the machine beeps normal but doesn't display anything and doesn't boot. After some testing I found out, that this only happens if one (of the two) monitors (Iiyama ProLite E2472HDD) is plugged in while booting. If the other monitor (TFT 2) is plugged in everything is fine. Here a small illustration, TFT 1 is the bad guy: TFT 1 | TFT 2 | failure x | x | x x | | x | x | After BIOS-Phase I can safely plug in TFT 1 and everything works just fine. The question is, what can be done to avoide this behavior: Change monitor? (Iiyama ProLite E2472HDD) Change graphics card? (GeForce 9800 GT) Other suggestions?

  • Select dropdown with fixed width cutting off content in IE

    - by aaandre
    The issue: Some of the items in the select require more than the specified width of 145px in order to display fully. Firefox behavior: clicking on the select reveals the dropdown elements list adjusted to the width of the longest element. IE6 & IE7 behavior: clicking on the select reveals the dropdown elements list restricted to 145px width making it impossible to read the longer elements. The current UI requires us to fit this dropdown in 145px and have it host items with longer descriptions. Any advise on resolving the issue with IE? The top element should remain 145px wide even when the list is expanded. Thank you! The css: select.center_pull { background:#eeeeee none repeat scroll 0 0; border:1px solid #7E7E7E; color:#333333; font-size:12px; margin-bottom:4px; margin-right:4px; margin-top:4px; width:145px; } Here's the select input code (there's no definition for the backend_dropbox style at this time) <select id="select_1" class="center_pull backend_dropbox" name="select_1"> <option value="-1" selected="selected">Browse options</option> <option value="-1">------------------------------------</option> <option value="224">Option 1</option> <option value="234">Longer title for option 2</option> <option value="242">Very long and extensively descriptive title for option 3</option> </select> Full html page in case you want to quickly test in a browser: <!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> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>dropdown test</title> <style type="text/css"> <!-- select.center_pull { background:#eeeeee none repeat scroll 0 0; border:1px solid #7E7E7E; color:#333333; font-size:12px; margin-bottom:4px; margin-right:4px; margin-top:4px; width:145px; } --> </style> </head> <body> <p>Select width test</p> <form id="form1" name="form1" method="post" action=""> <select id="select_1" class="center_pull backend_dropbox" name="select_1"> <option value="-1" selected="selected">Browse options</option> <option value="-1">------------------------------------</option> <option value="224">Option 1</option> <option value="234">Longer title for option 2</option> <option value="242">Very long and extensively descriptive title for option 3</option> </select> </form> </body> </html>

  • Does program need additional symbols from .so shared library except those declared in header file?

    - by solotim
    In C programming, I thought that a object file can be successfully linked with a .so file as long as the .so file offers all symbols which have been declared in the header file. Suppose I have foo.c, bar.h and two libraries libbar.so.1 and libbar.so.2. The implementation of libbar.so.1 and libbar.so.2 is totally different, but I think it's OK as long as they both offers functions declared in bar.h. I linked foo.o with libbar.so.1 and produced an executable: foo.bin. This executable worked when libbar.so.1 is in LD_LIBRARY_PATH.(of course a symbolic link is made as libbar.so) However, when I change the symbolic link to libbar.so.2, foo.bin could not run and complainted this: undefined symbol: _ZSt4cerr I found this symbol type is 'B' and it does not appear in libbar.so.2. Obviously this symbol has nothing to do with those functions I decared in bar.h. What's wrong here?

  • Visual Studio Express 2012 - Moving items to tab control loses actions

    - by JohnP
    VS 2012 Express on Windows 7 Professional, this was pre SP1 install. I have a windows form that I had several elements (Listboxes, buttons, text and labels), with some actions associated with changing indices on the list boxes and of course the button actions. I decided I wanted to add a tab control to enable a second tab with a different feature set, so I copied/cut/pasted all of the original items to a tab control that I added. When I did this, all of the elements lost their click action in the events window. I had to go and re-associate all of them. Is this a normal behavior/known issue, or is there some method to move controls that I am not aware of?

  • printing double in binary

    - by Happy Mittal
    In Thinking in C++ by Bruce eckel, there is a program given to print a double value in binary.(Chapter 3, page no. 189) int main(int argc, char* argv[]) { if(argc != 2) { cout << "Must provide a number" << endl; exit(1); } double d = atof(argv[1]); unsigned char* cp = reinterpret_cast<unsigned char*>(&d); for(int i = sizeof(double); i > 0 ; i -= 2) { printBinary(cp[i-1]); printBinary(cp[i]); } } Here while printing cp[i] when i=8(assuming double is of 8 bytes), wouldn't it be undefined behaviour? I mean this code doesn't work as it doesn't print cp[0].
