Linux – ps command in ubuntu

I observed that the recent Flash plugins do store files in /tmp, but they use a trick of removing them and keeping a filehandle open to keep them alive. This means they are still kept on the drive (as long as the filehandle is opened by flash plugin), but they are not visible in directory listing (because the file has been deleted).

I wrote about this some time age: getting flash videos from almost deleted files

But it all depends on version of Flash plugin. It used to store movies in /tmp or in browser's cache too.

You should also set correct permissions for .ssh folder and authorized_keys: chmod 700 ~/.ssh && chmod 600 ~/.ssh/authorized_keys Also, owner of these files should be the same as user trying to login.
