If there's some file, how can i forbid user to open it ? Ex. some text file or video file and forbid regular users (except root) to open/play it . Wouldn't chmod work here or should i use some other method ?
View 2 RepliesI want to forbid a user to make changes to preferences of iceweasel, specifically to modify proxy settings of the browser. Although user should still be able to use the browser.
I assume these settings are stored in some file on a harddrive? If so, what is this file and can i simply make it read-only for users? Or any other solution?
I have an application that creates temp files and quickly deletes them. But I'd like to keep those files, is there a way to do that in Linux?

View 2 Replies View RelatedI ran a program that writes continuously from 1 every line. After some time I ran '/dev/null > temp' Problem1: bash: /dev/null: Permission denied (Yes, the permissions of /dev/null are correct ... crw-rw-rw-. I removed and created it again, but no change) I used 'cat temp' to see the contents and first few lines deleted (working correctly). Problem2: I can't open the file (with double click or with any graphical editor like gedit)
Apart from these problems, I have another question... Is there a way to trim a active log file to say 80% without affecting any logs that server might be writing.
I am running an Ubuntu(10.04) box and I am attempting to understand an error in a program.I don't have access to the source of this program, but I know it isn't working properly because it cannot find a particular file. I was wondering if it would be possible to monitor what file are accessed(more specifically denied access) by a process. My first idea was to breakpoint on fopen, but I didn't have any success.

View 2 Replies View RelatedHow do you open a program, in this instance "Zenmap", from the desktop in a user account when it requires root privileges? Is there a way to be prompted for the password, the same way, for instance, you're prompted when mounting a new file system or making a change to the system? I tried entering 'sudo /usr/bin/zenmap' when creating the shortcut, however that didn't work.
View 3 Replies View RelatedI was just testing specifying limit on file size to a user and have added the following to /etc/security/limits.conf bob soft fsize 100 This basically should have said not to allow bob to create anyfile greater than 100Kb in size.
But the interesting thing is, if bob already has any file which is greater than 100Kb in size, it even doesn't allow to log him into the system both from console and SSH. Also nothing is logged in logs.. How do I configure it so that, bob can login to the system even though he has any file greater than 100Kb (but doesn't allow him to create file which are greater than 100Kb) ??
