This cannot possibly work. Every running program has its own copy of the
environment variables. You are only setting http_proxy in the shell that
is currently interpreting the network.opts file.
You could try the following: Change the commands above to write the
proxy to a file in the /etc directory. Then change the bash init file
(eg. ~/.bashrc or profile or whatever) to set the proxy variable from
this file. This will only work for newly started shells.
Alternatively, always use a local proxy on your laptop and change its
configuration to forward the requests to the real proxy.
