permissions

问题 I'm writing a WebRTC app that is designed to be used from an Android tablet. When you access the app, Chrome prompts you to Allow or Deny access to the camera/microphone. According to this page (https://support.google.com/chrome/answer/2693767?hl=en), if you host your app behind HTTPS, then browsers will remember the setting you chose. This works correctly in Chrome on the desktop (Mac, Linux) but when I visit the same site in Chrome Beta for Android (v29), it prompts me to Allow/Deny each

问题 I can't get the openssh server to work on Windows Server 2008. I have it working on two other servers, but one of them just won't work. I run ssh-host-config , and choose privilege separation. Two users are created sshd and sshd_server . Then I run net start sshd , and I see this: The CYGWIN sshd service is starting. The CYGWIN sshd service could not be started. The service did not report an error. Then I run cat /var/log/sshd.log and I see this output: /etc/sshd_config: No such file or

问题 The Android documentation contains the following description of the adb grant and adb revoke commands. Use the adb tool to manage permissions from the command line: List permissions and status by group: $ adb shell pm list permissions -d -g Grant or revoke one or more permissions: $ adb shell pm [grant|revoke] <permission-name> ... Analyze your app for services that use permissions. i run this command, without any error message: abd shell pm [grant|revoke] com.my.app android.permission.ACCESS

问题 I have a windows Application that stores certain files in a directory. I would like to know if there is a way in .net that I can restrict users not to have access to that directly (by just going to that directory in windows, and grab files) so only my application can add/verify/delete a file in that directory. 回答1: Could you use the Isolated Storage in .Net? While, it isn't necessarily restricted away from your users it may be a lot harder to find.... (stores under the local settings

问题 Supposing, I have two users in Postgres 9.6 named user1 and user2 . I want to make permissions to user2 on any new table created by user1 without extra explicit grant commands for the created table. In other words, I want to make the following commands work correctly: Giving permissions to user2 ( I don't know what should be here! ) CREATE TABLE t1 (id int) (under user1 ) INSERT INTO t1 VALUES (5) (under user2 ) Please, notice, I am not supposed to make any permissions between step 2 and 3.

This is what it looks like... <activity android:name=".widgets.WidgetConfigurationActivity" android:theme="@android:style/Theme.Translucent" android:exported="true" > <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_CONFIGURE" /> </intent-filter> </activity> The warning I'm getting is "Exported activity does not require permission".

问题 I'm new into Symfony 2 and I read some docs about ACL and the ROLE System. I understood that I can use different Permissions on a Object with ACL. But I need some different ( ? ) type of permission check, like in the static apache turbine roles / permission sets. I want to use FOSUserBundle and using Groups. The Groups should have permissions like DOWNLOAD_PDF DOWNLOAD_PPT INVITE_USERS and so on.. Stuff that does not have something to do with Objects but I have to check in Controller ( static

问题 I initially asked a question about how to create linux users via HTML (essentially the user registers via an HTML page which executes a server side PHP script which more or less issues the command shell_execute("adduser user") . But, since then, I have come to realize that the problem has to do with the Apache user. The default apache user is www-data. This works fine most of the time, as you can assign files or folders to either the www-data user, or the www-data group. However, it
