privileges

问题 I have a Python app that I'm working on that needs to access the hosts file to append a few lines. Everything worked on my test file, but when I told the program to actually modify my hosts file in /etc/hosts I get IOError 13. From what I understand, my app doesn't have root privileges. My question is, how can I circumnavigate this issue? Is there a way to prompt the user for their password? Would the process be any different if I was running the app on a Windows machine? Here's the code in

问题 First of all, I'm kinda new to web programming and programming in general. HTML/CSS + Javascript are as far as I've gone over the last few years. Now, for the purpose of my work, I need to learn PHP. What I'm most interested about is user registration + users' privileges. My task is to create a web application that is, let's say, a simpler version of a blog. I'd like to know is it possible to build such an application from scratch and add users with different privileges. And, if so, what is

问题 Please tell me a way grant for my application to modify /Library/Fonts folder as add new and remove font file.

Still it works You can run some command via NSAppleScript using "do shell script \"some script\" with

问题 I know this issue has already been raised by others, but even trying previous suggestions I still get this error... When I try to populate a table copying from a csv file, I get a permission error. COPY Eurasia FROM '/Users/Oritteropus/Desktop/eurasia1.csv' CSV HEADER; ERROR: could not open file "/Users/Oritteropus/Desktop/eurasia1.csv" for reading: Permission denied SQL state: 42501 As previously suggested in these cases, I changed the permission of the file (chmod 711 eurasia1.csv or chmod

问题 Error description I'm unable to mount files in Vagrant or Docker, so it seems like it's an issue caused by some kind of a permission error. My OS is Ubuntu 18.04 LTS (Bionic Beaver) , I'm not running any access control modules like SELinux as far as I'm aware. The Docker-related discussion of the error is found in another question: Unable to mount files in Docker Troubleshooting Vagrant As a result I'm unable to mount files into Vagrant boxes (even though I have vboxsf): Vagrant was unable to

问题 i have two databases, db1 and db2. User man1 had all privileges to db1 but only executing provileges for all functions and procedures in db2.

Now somthing really strange happens: The first

问题 For every new user we create in mySQL using the statement CREATE USER newuser@localhost IDENTIFIED BY 'password'; "SHOW GRANTS" is showing only "USAGE ON *.* " privilege.

问题 I am trying to open an existing physical file from file system in a procedure in Oracle 10g. The bfilename function requires a directory and path. I want to pass on the directory such as "c:\abc" directly to the procedure, i.e. I don't want to pass a directory object. The reason is, the directory can change, and I don't know how to create or replace directory inside a procedure (the command always returns error saying that variable is not allowed). I also am not sure about how it works in a

问题 I need to run some commands on my ubuntu box where my django project resides that requires root privileges, from within my django project. I'm using celery to fire off an asynch process, this process in turn calls shell commands that requires root privileges to succeed. How can I do this without risking creating huge security holes? PS! The shell commands I need to call are smbpasswd, edit /etc/samba/smb.conf and restart the samba service. 来源： https://stackoverflow.com/questions/3767841/using
