Thanks. Hmmm, well if I remember my unix file system university lectures correctly, you can remove the ability to see a file or directory by removing the read permission for it, so that the permitions would be something like: drxxx I think you'd need to set something like 711 permitions with chmod. It wouldn't stop someone going in there, so you could still modify the files because you know the directory is there, however unless someone knows the exact name of the directory, they'll never find it. If you were going to do this, however, you'd needto put the chmod command into your startup scripts somewhere, as the /proc file system is non-transient.
