UPnP AV Client on Linux

If you have been messing around with UPnP media servers like mediatomb it is a good idea to have a UPnP Client installed in your Linux box. I use djmount for this purpose.

The following methods are tested on Debian Lenny (testing) to install and run djmount and should work with any other Linux distribution with the only change of installing FUSE.

How to configure Proxy Settings for the Linux Console and APT

You can use the following methods to configure your console to use a proxy server so that console based programs like wget could get connect to the internet through the proxy.

1 - Set the environment variable
# export http_proxy=http://DOMAIN\USERNAME:PASSWORD@SERVER:PORT/
# export ftp_proxy=http://DOMAIN\USERNAME:PASSWORD@SERVER:PORT/

In the above configuration you can ommit the DOMAIN\USERNAME:PASSWORD@ part if you are not using proxy authentication.
