LLE10138 : Posix error 13: Permission denied

Symptom:

You get the error message: Permission denied

Cause:

none

Solution:

e.g. cat: myfile.txt: Permission denied

A permission denied message is most of the time due to user rights.

A good place to start is the permission on the filesystem.

Here is a list of some commonly used settings, numerical values and their meanings:

-rw------- (600) — Only the owner has read and write permissions.
-rw-r--r-- (644) — Only the owner has read and write permissions; the group and others have read only.
-rwx------ (700) — Only the owner has read, write, and execute permissions.
-rwxr-xr-x (755) — The owner has read, write, and execute permissions; the group and others have only read and execute.
-rwx--x--x (711) — The owner has read, write, and execute permissions; the group and others have only execute.
-rw-rw-rw- (666) — Everyone can read and write to the file. (This is dangerous!)
-rwxrwxrwx (777) — Everyone can read, write, and execute. (This is dangerous!)

Here are some common used settings for directories:

drwx------ (700) — Only the user can read, write in this directory.
drwxr-xr-x (755) — Everyone can read the directory; users and groups have read and execute permissions.

Please note that even the root user can run into this errormessage!

When this error comes when mounting a filesystem, you should check your /etc/exports file and make shure the volume is exported and your client has the right to access it.

If the error comes when running a program on a mounted filesystem, look at the options of the mounted filesystem. E.g. can you run programs from it at all?
