# are guaranteed to stay up for years, make sure this var is set
# correctly else the ubuntu instance WILL run out of disk space.

# Note that from time to time it is also advisable to run this,

# Copy the 'ray mode' version of the udp-proxy code down here,
# noting that I manually keep this code up-to-date with respect
# to the code in the hub repo's udp-proxy folder.
git clone https://github.com/blues/udp-proxy.git
cd udp-proxy
go build

# Add this to the crontab so that it automatically starts on boot
crontab -e
# add this line
@reboot screen -dmS udp-proxy /home/ubuntu/udp-proxy/run.sh

# Start it up
sudo reboot

# After you come up, do this command to see if it is running in
# the background.
screen -ls

# In order to switch to it, use this command (which works because
# it should be the only screen session running).  SEE NOTE BELOW.
screen -r

# NOTE that when you are in the screen session above, these are
# the absolutely essential things to remember:
ctrl-a d       // Detaches the screen session and returns to bash
ctrl-a <ESC>   // Allows you to use arrow keys to scroll back to

# While you are in the screen session, remember that typing
# the letter 'q' followed by <enter> will quit the session,
# re-pull the latest code from the repo, and restart the
# udp proxy server.  This is the way to re-deploy updates.
