View Full Version : file sysyem doesnot work, why? Please help

26th August 2007, 03:01 AM
I use linux just for a short time. And one time I double cilck a *.exe file by mistake.

That EXE file is about installing a sound card drive in Windows system. After that, my language bar doesnot work. And I cannot open all the help document in any software.

The SELinux says that "SELinux is preventing access to files with the default label, default_t." and "Affected RPM Packages: procmail-3.22-19.fc7 [application]filesystem-2.4.6-1.fc7 [target]".

I really don't know about information that SELinux provide. I don't have enough knowledge about that.

So is there anyone can help me?

Thank you very much!

============================below is what SELinux tells me ==========================

SELinux is preventing access to files with the default label, default_t.

Detailed Description
SELinux permission checks on files labeled default_t are being denied.
These files/directories have the default label on them. This can indicate a
labeling problem, especially if the files being referred to are not top
level directories. Any files/directories under standard system directories,
/usr, /var. /dev, /tmp, ..., should not be labeled with the default label.
The default label is for files/directories which do not have a label on a
parent directory. So if you create a new directory in / you might
legitimately get this label.

Allowing Access
If you want a confined domain to use these files you will probably need to
relabel the file/directory with chcon. In some cases it is just easier to
relabel the system, to relabel execute: "touch /.autorelabel; reboot"
