Steps to configure SSL for Apache HTTPD server on Windows: In Apache2.2/conf/httpd.conf , load mod_ssl and include httpd-ssl.conf : LoadModule ssl_module modules/mod_ssl.so ... In Apache2.2/conf/extra/httpd-ssl.conf , make sure the paths for the cert files point to the cert and key you want to use: # Server Certificate: # Point SSLCertificat... Start up Apache. If it fails, use the command line to see what the error is. There won't be any log in error.log if there are errors in the conf files: C:\Program Files (x86)\Apache Software Foundation\... I corrected the previous error by using the alternative line for SSLSessionCache : # Inter-Process Session Cache: # Configure ...

The Android unit test framework is based on JUnit 3 , not JUnit 4. Test cases have to extend junit.framework.TestCase or a subclass (such as android.test.InstrumentationTestCase ). Tests are identified by public methods whose name starts with test , not methods annotated with @Test (as in JUnit 4). An Android test suite is packaged as an APK, just like the application being tested. To create a test package, first you need to identify the application package it is testing. Google suggests to put the test package source in a directory named tests/ alongside the src/ directory of the main application. At runtime, Android instrumentation loads both the test package and the application under test into the same process. Therefore, the tests can invoke methods on...

The error was created by android.content.pm.PackageParser , which compares the android:minSdkVersion and android:targetSdkVersion attributes of the uses-sdk element of AndroidManifest.xml in the APK file against the SDK version of the device or emulator. The SDK version on the device has to be greater than that required by android:minSdkVersion . In my case, since I built the package with AOSP, the target emulator has to be AOSP also. This is the relavant section in AndroidManifest.xml : <uses-sdk android:minSdkVersion="AOSP" ... And the relevant section in android.content.pm.PackageParser : if (minCode != null) { if (!minCode.equals(...

Both include and require include and evaluate the file specified as argument. The only difference is, when the included file cannot be found, include emits a warning while require emits a fatal error. Example: <?php include('non-existing-file'); require(...

You get "permission denied" error from Apache HTTPD for a page. And you checked file/directory permissions (the whole directory path, not just the file) and everything in httpd.conf . If everything seemed right, then SELinux may be blocking the access. Open /var/log/httpd/error_log , you may see a line like this: [Wed Apr 13 15:50:35 2011] [notice] SELinux poli... These are the steps to fix: If the directory resides in a user home directory: # setsebool -P httpd_read_user_content 1 Create a policy package from the audit log: # grep httpd /var/log/audit/audit.log | audit2allo... Apply the policy package just created # semodule -i mypol.pp Restart apache httpd: # apachectl restart

grep is a versatile command with many variations (grep, egrep, fgrep, then various implementations). It uses a regula expression (regex) pattern to filter input. But then there are basic and extended flavors of regex - leading to even more confusion. And, beware that there are lots of bad examples of regex in the wild... There are two critical questions to ask when you use grep: which grep implementation are you using? what is the flavor of the regex? Here are some examples for gnu grep v2.7: # Find all numbers (no decimal point), basic regex... Use the -o flag to show only the matching part instead of the whole matching line: grep -o -E '\b[0-9]{2}\b' The good thing about the gnu grep is that it...

I'm running 64-bit Fedora but Android adb is looking for 32-bit Linux loader. This is resolved by installing the 32-bit libraries. # yum whatprovides ld-linux.so.2 Loaded plugins... I did the same for libncurses.so.5 and libstdc++.so.6 to resolve all dependencies.

cURL is a command line tool for transferring files with URL syntax. The main purpose and use for cURL is to automate unattended file transfers or sequences of operations. It's really easy to see HTTP headers with curl: C:\>curl --head http://www.google.com HTTP/1.0 ... or, headers and page together (dump headers to stdout): $ curl --dump-header - http://www.google.com HTTP/...

This is the error: >>> import urllib2 >>> f = urllib2.urlopen('htt... Reason: SSL is not supported in Python installation. >>> import httplib >>> hasattr(httplib, 'HTTPS'... Solution: recompile Python with SSL on Steps: Download and install OpenSSL , if you don't have it already. Download Python source and rebuild Python (the usual steps of configure, make and make install). Python's configure script should be able to pick up your existing SSL libraries automatically and build a shared library _ssl.so. Some web sites suggest editing the file Modules/setup.dist , uncomment the lines starting with _ssl , and making changes to the SSL path. This would link the SSL library statically to Python. # Socket module helper for socket(2) #_socket s...
