I only just figured out how to run Sage in a daemon/service-like kind of state - see http://ask.sagemath.org/question/23431/running-sage-from-other-languages-with-higher-performance for the Sage script.

Now I'm trying to rewrite it to Python with Sage imports, so I can automatically start it with `sage -python [PATH TO SCRIPT]`

as opposed to manually starting Sage and loading the script.

The fails with the following stack trace

```
Traceback (most recent call last):
File "socket.py", line 1, in <module>
import socket
File "/var/www/lingapps/assets/sage/socket.py", line 4, in <module>
import sage.all
File "/var/www/lingapps/assets/sage/local/lib/python2.7/site-packages/sage/all.py", line 54, in <module>
from sage.env import SAGE_ROOT, SAGE_DOC, SAGE_LOCAL, DOT_SAGE, SAGE_ENV

_add_variable_or_fallback('HOSTNAME', socket.gethostname())
AttributeError: 'module' object has no attribute 'gethostname'
```

This also happens when I have just a single line in the script: `import sage.all`

.

It also fails with the following error if I just start `sage -python`

and type `import sage.all`

:

```

```

I'm following the method explained at http://www.sagenb.org/doc/static/faq/faq-usage.html (How do I import Sage into a Python script?).

I assume it has something to do with the enviroment variables, but I can't seem to find any documentation about that on the Sage website so what to do?

I'm running Sage 5.13 on Debian - not installed via `apt-get`

, just downloaded and unpacked.
