A hackety hack function to toggle SSH/SOCKS proxy on OS X Mavericks

toggleproxy.sh

function toggleproxy {
  # checks to see if SOCKS proxy is enabled
  if [[ $(networksetup -getsocksfirewallproxy Wi-Fi | grep '^Enabled') == "Enabled: No" ]]; then
    networksetup -setsocksfirewallproxystate Wi-Fi on
    echo "SOCKS on!"
      # checks to see if there's an existing SSH tunnel and if not, it starts one
      if [[ -z $(ps aux | grep '[0-9] ssh -D 8080') ]]; then
  	    echo -ne "Don't see a ssh tunnel on 8080 active, starting one now..."
  	    ssh -D 8080 -f -C -q -N USERNAME@HOSTNAME.EDU   # Change this from the defaults!
  	    [[ $? == 0 ]] && echo " success!" || echo " failed :("
      fi
  else
    networksetup -setsocksfirewallproxystate Wi-Fi off
    # only show this message if there's an active SSH tunnel
    if [[ -n $(ps aux | grep '[0-9] ssh -D 8080') ]]; then
      echo "SOCKS off! You may want to kill your existing SSH tunnels with 'killtunnel'."
    else
      echo "SOCKS off!"
    fi
  fi
}

function maketunnel {
  ssh -D 8080 -f -C -q -N USERNAME@HOSTNAME.EDU # Change this from the defaults!
}

## kills all SSH connections with port forwarding to 8080
function killtunnel {
  for x in `ps -u $USER | grep -P '[0-9] ssh -D 8080' | awk '{print $2}'`; do
    kill $x
  done
}

I'm not sure if you still use this but my fork has some fixes, mainly I added a kill command after the networksetup turns the socks proxy off and made sure that Wi-Fi and Ethernet both get the proxy.
