  प्रतिध्वनि प्रणाली ("/ usr / bin / whoami", $ ret); प्रतिध्वनि $ ret;

अपाचे 2.0.52 पर PHP 4.3.9, CentOS 4.5। सुरक्षित मोड बंद है, मैं कमांड लाइन से अपाचे यूजर अकाउंट के रूप में प्रोग्राम चला सकता हूं, लेकिन PHP से चलने वाले सभी प्रोग्राम 127 कोड से असफल होते हैं।

  • देखें कि / usr / bin / whoami मौजूद है, और किसी के द्वारा निष्पादन योग्य (और पठनीय, मोड xx5 ) है
  • php.ini पर doc_root और user_dir देखें, यदि वे सेट होते हैं तो आप उन्हें निष्पादित कर सकते हैं। / Li>
  • यदि आपका अपाचे या PHP क्रोधित है, तो आपको एप्लिकेशन को चुराने में क्रियान्वित करने की आवश्यकता है।
  • मशीन पर कुछ अन्य सुरक्षा प्रणाली या आरबीएसी चल रहा है, तो देखें / var / log / में dmesg या लॉग फाइलें
  • के बजाय & amp; $ ret का उपयोग करना न भूलें > $ Ret ।
  • PHP का exec () और passthru () देखें, अलग-अलग कार्य विभिन्न स्थितियों के लिए काम कर सकते हैं।
  • पता है कि अपाचे के लिए एक अलग php.ini है, और एक भिन्न है सीएलआई उपयोग के लिए एंट एक।

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for.

To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
