Deleting, linking, and renaming files require execute permission too, as discussed below.  This is because such operations also require access to a file's inode in addition to the file's name.  While read permission will allow access to the name of a file in a directory, execute permission is needed to access the inodes of files in that directory.

chmod 0700 /opt/lampp/lampp

Точнее,

The execute permission <...> When set for a directory, this permission grants the ability to access file contents and metainfo if its name is known, but not list files inside the directory (unless read is set).
