Permission denied while accessing pseudos

[Yoanis Gil Delgado]

Hi there. I've been playing around with pseudos and whenever i try to access a 
pseudo dir or file i get a Permission denied error. For example:
        $ ls hello.txt/..../rwx
        Permission denied
I also tried 
        $ ls hello.txt/..plugins/rwx
         Permission denied
I also tried to list a missing plugin and i get the same error. For example
        $ ls hello.txt/..../pepito
        Permission denied

Thanks.........
