Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

samba

#!/bin/sh

# This assumes you have access to the system via SSH already, and need 
# remote VNC access as the same user, and you want only the primary display.
export DISPLAY=:0

# Encoded password with http://www.motobit.com/util/base64-decoder-encoder.asp
export VNC_PASSWORD="dm5jX3Bhc3N3b3JkNzE="  # vnc_password71
export VNC_PASSWORD="dm5jX3Bhc3M=" # vnc_password (a character limit is enforced?)
# Sadly many common VNC clients don't support encryption.
