linux - Authenticating GTK app to run with root permissions -


For Linux, a UI app (uses GTK) must be run as a root (it reads and / dev / writes)

SD *).

While the user needs to open the root app or use "sudo" manually manually, I wonder if the app can access some OS-provided APIs for root permissions. (Note: GTK app's "Setuid" mode can not be used, so this is not an option.)

Here the benefits will be an easy workflow: the user can double-click the user's default user account Instead of opening a root terminal and launching it from there, my app from desktop

I ask this because OS X offers exactly this type: An app can ask OS to execute executable with root permissions - OS (and no app) then the user will have to Asks to input credentials, verifies them and then launches the desired target.

I am surprised that something similar is for Linux (like Ubuntu)

Explanation:

< P> So, after the signal on the monitored I wonder if I use r / w to use "/ Dev / sd ..." block device I think it is very difficult to understand, so I have Was asked before that before I could spend it in hours to understand it in vain it is possible.

Update:

Escape is a remote operating disk repair tool for unusual Linux users, and sudo to those Linux nodes Would not have much understanding of using or even changing their user group membership, especially if their discs just started acting and they are angry, this is the reason why I find a solution that is similar to the technical Avoids

The old way, simple but now being phased out, is the discussion of the future of GKSU .

To use the new way I'm pretty sure how it works, but I think you need to use your code with the pkexec command.

Update:

Looking at the example code, it looks like you have the .policy files in / usr You can use PolicyKit to obtain authorization for some of the tasks described by / share / polkit -1 / action . The action to implement a program as another user is org.freedesktop.policykit.exec . I am not getting any work to reach the block device directly, but I have to admit that the policycit documentation breaks my mind too.

Therefore, the easiest way to act for you is to have your disk-mangling code privileged in a command line utility, and it should be g_spawn_ [a] sync () With the pkexec can be run from your GUI application. In this way, you will not have to bother with requests for action and things like that. This is probably a bad practice, so that your entire GUI application can be run as a root.

Another suggestion is to ask directly to the author of PolicyKit (David Zethane) or try posting on your question gtk-app-devel list.

bytearray - Removing trailing nulls from byte array in C# -

OK, I'm reading in a file byte array. For some reasons, people who generate these files, at the end of the file, tell about the value of one half manga worthless nail bytes. Does anyone know what's a quick way to trim them at the end? At first thought that starting from the end of the array and starting again the last time until I found nothing other than a null, but I am surprised that there is no better way. To answer some questions: Are you sure of 0 bytes in the file, instead there is a bug in the file reading code? Yes, I'm sure of this. Can you definitely trim all indexed 0s? Yes Can anybody have any file in the rest of the file? Yes, there may be other places of 0, therefore, no, I can not start at the beginning and can not stop at the first 0. Now answering additional questions, it seems that you are doing the right thing in the right way Specifically, to touch every byte of the file from the previous 0, to check that it has only 0s. Now, whether ...

WPF TextBlock Overflow Text to the Left -

As a backdrop, I have a very long identity which is too long to be displayed in the given area of ​​the text block. The interesting part of the ID is the end, this is the right part. What I would like to do, instead of moving the text upwards, the text box, and cutting the right part, left the overflow and This is by default as compared to the code 1234 . I can manually trim my ID for display, but a variable space font that is not ideal. So, there is no way to change the WPF overflow direction? Is this effect you are trying to take?
