privileges

问题 I found out how to deny all access to tables for user in a schema. REVOKE ALL PRIVILEGES ON SCHEMA test FROM user; But what can i do to restrict access to all functions in a schema, so that user couldn't read the code? I was trying this: REVOKE ALL ON FUNCTION test.test_function(text) FROM user; Yes, it has restricted the ability to change a function, but not to actually see it. What have i missed? 回答1: REVOKE access to the system view pg_proc or at least the column prosrc that hase the

问题 I have a multi-schema, multi-user Postgres DB. There is one table that I would like ALL users, both current and future, to be able to SELECT from. I can GRANT SELECT to all current users... but how can I create a table that allows any future user to select? Is there a way to set table permissions , rather than granting user privileges ? A filesystem analogy would be using chmod to make a file to be readable by the public. 回答1: grant select on the_table to public; From the manual: The key word

问题 My net.pipe WCF binding does not work when the server runs non elevated. This blog helped me find the answer - http://weblogs.thinktecture.com/cweyer/2007/12/dealing-with-os-privilege-issues-in-wcf-named-pipes-scenarios.html So, I added the SeCreateGlobalPrivilege privilege to the relevant non admin user, but now I have to enable the privilege programmatically in .NET Now, there are several examples on the internet how to do it in .NET, but all of them essentially rewrite plain C code to C#

问题 This is a userAdmin vs. userAdminAnyDatabase question. In the system.users I have the following users (password 1234 for both): > db.system.users.find() { "_id" : ObjectId("52a976cb7851682aa44d6d4d"), "user" : "admin_one", "pwd" : "884f516cf308a4c6a75bbc5a0a00807b", "roles" : [ "userAdmin", "dbAdmin" ] } { "_id" : ObjectId("52a97c697851682aa44d6d4f"), "user" : "admin_two", "pwd" : "26e7bb644e5919461cd6ba7403dc6906", "roles" : [ "userAdminAnyDatabase", "dbAdminAnyDatabase" ] } Connecting with

问题 I'm having trouble granting privileges to another user in PostgreSQL 8.3. While the GRANT command gives me no error, the privileges do not show up. Do I need to "flush" them? sirprize=# CREATE DATABASE testdb; CREATE DATABASE sirprize=# GRANT ALL PRIVILEGES ON DATABASE testdb TO testuser; GRANT sirprize=# \c testdb You are now connected to database "testdb". testdb=# \z Access privileges for database "testdb" Schema | Name | Type | Access privileges --------+------+------+-------------------

问题 I have searched quite a bit on the subjects of encryption, storing passwords, designing secure PHP scripts etc. There seems to be a couple of common themes: "Don't try and write your own encryptions scripts, use an existing library (eg. PHPass)." "Don't create MySQL databases for each user, make one big database and write a good PHP script to manage your users, passwords and their data." Now, is it me, or do these two not seem a bit conflicting? Let's take this example. I want to create a

问题 I accidentally did something a bit stupid and typed this into the mysql console: mysql> grant all on myDB.* to root@'%' identified by 'root'; ... and the db configuration is open to remote logins. Now I need to remove this grant but don't want to accidentally revoke all privileges for my root user and effectively lock myself out of the db as the db admin. What should I do? 回答1: First, verify that your root@localhost and/or root@127.0.0.1 users have access. SHOW GRANTS FOR root@localhost; SHOW

问题 i want to execute a setup.exe installer which installes a software on vista with java 1.6. The user is not an administrator. When i try to start the process i get the error message: CreateProcess error=740 which indicates, that the user has not enough rights for starting the process. Can i submit a flag or an option to indicate, the the process should execute with administrator rights? Vista itself does have this functionality inside the menu toolbar. Can i use this function in Java. I call

问题 I created a user (new_user) with root like this: GRANT ALL ON labor.* TO 'new_user'@'%' WITH GRANT OPTION; GRANT ALL ON labor.* TO 'new_user'@'localhost' WITH GRANT OPTION; GRANT CREATE USER ON *.* TO 'new_user'@'%'; GRANT CREATE USER ON *.* TO 'new_user'@'localhost'; GRANT RELOAD ON *.* TO 'new_user'@'localhost'; GRANT RELOAD ON *.* TO 'new_user'@'%'; FLUSH PRIVILEGES; When I try to create another user the same way but with new_user, I get an access denied error. This error occurs after the

问题 Is there a way to request elevated privileges from the os, for "just a part" of a c# program? I'm writing a bunch of integrationtests using NUnit. One of the things I'm testing is if the application under test correctly connects to port 843. The test opens a listening socket at port 843, and then throws all sorts of responses to the application under test, and verifies if the application behaves correctly. Opening a listening socket on port 843 requires admin privileges however. I'd like to
