Please read How (Not) To Ask A Question.

The edited code was intended to point out several issues with your original post. Did you read the edited code and comments I made on your original? Do you understand why sock is a lousy name for a subroutine, even if it has some relationship with a socket (hint: what does it do to/with the socket)? Do you understand why I made the changes I made? Whether or not the the changes fixed the problem you posted about, is really only a tiny part of the point of my response.

Unless your problem statement managed to mislead all of your respondents, you should have enough information to fix your code.

Finally, based on what you have said about saving protected names in a file, you really should be chomping the values after you read them.
