Restricting Symbolic Links (Unix/Linux)
You can limit the use of the file system links in your server. File system links are
references to files stored in other directories or file systems. The reference makes
the remote file as accessible as if it were in the current directory. There are two
types of file system links:
•
Hard links—A hard link is really two filenames that point to the same set of
data blocks; the original file and the link are identical. For this reason, hard
links cannot be on different file systems.
•
Symbolic (soft) links—A symbolic link consists of two files, an original file
that contains the data, and another that points to the original file. Symbolic
links are more flexible than hard links. Symbolic links can be used across
different file systems and can be linked to directories.
For more information about hard and symbolic links, see your Unix/Linux system
documentation.
File system links are an easy way to create pointers to documents outside of the
primary document directory and anyone can create these links. For this reason you
might be concerned that people might create pointers to sensitive files (for
example, confidential documents or system password files).
To restrict symbolic links, follow these steps:
From the Class Manager, click the Content Management tab.
