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.

Then you will need to logout and log back in for changes to take effect or you can run this command.

 ~> source .bashrc

And that's it. Simples.

Email

Outbound email may be routed through mailhost.vmsrv.redbrick.dcu.ie (136.206.16.254). Inbound email can not be accepted. For more information see the documentation on configuring exim to send mail from your vm
