First steps in configuring linux server for remote access.

When setting up a new Linux server (in a corporate network) for remote debugging/ssh/whatever, you'll first need to install openssh-server if it isn't installed already. To use apt-get, ensure you have a proxy set up. It is likely you'll need to modify/create /etc/apt/apt.conf, and add the following line to it.

Acquire::http::Proxy "<your-proxy-address-here>:<port>"

After doing this, you should be able to use apt to update and install the latest openssh-server package.
