The file netflow.tar.Z (located in the parent of this directory) is a compressed tar file containing all the netflow subdirectories and files. It is updated periodically. If you want it, do the following: Set ftp mode to binary. Get the file to your local system (from the parent directory of netflow). $ uncompress netflow.tar (note no .Z in command) $ mkdir subdir $ cd subdir $ tar xf ../netflow.tar You will now have the entire netflow directory structure in your subdirectory.
