Type "help", "copyright", "credits" or "license" for more information.Okey after compiling from source python 3.3.2 and 'easy_install pymysql' now i'm receiving this error whiuch prohibit my files.py script to run.

=====================================
(e-mail address removed) [~/www/cgi-bin]# python files.py
Error in sys.excepthook:
ValueError: underlying buffer has been detached

Original exception was:
Traceback (most recent call last):
File "/usr/local/lib/python3.3/os.py", line 673, in __getitem__
value = self._data[self.encodekey(key)]
KeyError: b'REMOTE_ADDR'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "files.py", line 17, in <module>
host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0]
File "/usr/local/lib/python3.3/os.py", line 676, in __getitem__
raise KeyError(key)
KeyError: 'REMOTE_ADDR'

=====================================

host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0]

Is not the proeblem here becaus ei ahve the exact same statemnt inside metriets.py and pelatologio.py and they dont provide me an error.

If i run the script from chrome as http://superhost.gr/cgi-bin/files.py
i get na internal server error.

But since it complained i switched the above host to host = "nikos"

then run python files.py and it compiled properly with no error
but via browser i receive internal server error agian.

So since the script interprets okey i decided to tail the error log to see the live error messages when i call it via browser:

i tried somehtign else too.

uploaded 1.mp3 and 1.exe from windows 8 via FileZilla to linux webhost

and then renamed them both to Greek letters so that the renaming take place from within the CentOS and after that i tried:

http://superhost.gr/cgi-bin/files.py

Guess what? Still same error
