I seem to remember encountering a similar error. If I remember well the culprit was Ubuntu Firewall which kept al ports (with the possible exception of port 80) closed. Since I'm not very worried about security questions I justed turned off the firewall:

sudo ufw disable

and restart the system. (Again: if I remember well. It might have been 'ufw -disable', so consult the help system).

I am running Ubuntu 12.10 i386 on Vostro 3500 dell laptop.

This is the error:

sage: notebook()

Any help of how to resolve this error will be greatly appreciated

I have tried typing, "%fortran" and it failed, what I want is to install f2py in such a way that Sage registers it. It doesn't come with the Sage package.

Basically as per title, I've tried downloading the tarball and going from there but it always fails to register as installed. I have python 2.7 already but installing NumPy and SciPy the manual way so that f2py recognises it has failed me.
