Proxy Access

All outbound http(s) traffic must go through the proxy - proxy.vmsrv.redbrick.dcu.ie (136.206.16.254) port 3128

Ubuntu

To make sure apt uses the above proxy server, you need to add a file to /etc/apt/apt.conf.d/ and put the details into it. Here's how you do it:

 ~> cd /etc/apt/apt.conf.d
 ~> sudo nano proxy

You'll be asked to enter your VM password at this point, before nano starts.

In this new file (proxy), type the following:

 Acquire::http::Proxy "http://proxy.vmsrv.redbrick.dcu.ie:3128";

Hit Ctrl-x, then "y" to save the details.

To set your proxy system-wide you will need to edit you shellrc file. By default this is .bashrc on Ubuntu. Here's how you do it:

 ~> cd $HOME
 ~> nano .bashrc

Add the following lines to end of this file

 export http_proxy="http://proxy.vmsrv.redbrick.dcu.ie:3128";
 export https_proxy="http://proxy.vmsrv.redbrick.dcu.ie:3128";
 export ftp_proxy="http://proxy.vmsrv.redbrick.dcu.ie:3128";

Hit Ctrl-x, then "y" to save the details.

 ~> source .bashrc

And that's it. Simples.
