I wnnt to the trac tickets page you referenced, and applied all the
patches as shown there.
But it does'nt seem to solve the problem!

Here is what happens (again, inside emacs)

I will try, but since I have not done this sort of things with sage before,
¿How to do it? It is as simple as drop-in repacing one (or a few files) All
the files have the same name(s) as corresonding old files, so now change to

Well, this is not strictly true. It is only true if the server is
listening on port 80 on interface 0.0.0.0. If it is listening on
interface 127.0.0.1 then it will only accept local connections; if it
is listening on any other interface x.y.z.w then it will only accept
connections addressed to recipient "x.y.z.w".

Do you have iptables and/or shorewall configured and running on your 
laptop?  That is one program that could be preventing sage from opening 
ports. If it is none of the above, then I don't know how to help you.

I don know of any firewalls I have installed, and I can't imagine how any
firewall on the university' s

  My problem with answering is that I don't really know anything about
"ports" . I guess that has something to do with networking,
but nbothing more! Any hints about books/papers/netplaces to read to learn
about "ports"?
