Arch Attempt

This community Arch AMI worked:  arch-linux-x64 (ami-2e37c747)
...until I tried to reboot it :(

This looks like a decent dns service: freedns.afraid.org

Trying this one:  ami-0456b66d (i386)

pacman -Syu
useradd $u
passwd $u   (I used the cookie one...)
mkdir /home/$u
chown $u /home/$u
pacman -S sudo
vim /etc/sudoers
pacman -Syu openjdk6
pacman-db-upgrade
pacman -Syu openjdk6

Example AMI Attempt (Amazon linux with yum)

Already has java.

sudo yum install screen -y
sudo yum install mutt -y
sudo yum install tree -y


java -Xmx1024m -jar sat.jar | tee output.txt




SCREEN

screen -S SESSIONNAME
screen -list (works great from inside session)
screen -r SESSIONNAME

MUTT

Woah.  So, mutt has some weird ass interactive mode that I never even noticed until I forgot to pipe cat to it!  Wow.  Anyway.

cat | mutt -s test2 EMAIL@gmail.com
cat output.txt | mutt -s "Sat Results" EMAIL@gmail.com

-a for attachment, -i for body, -s for subject, however if you use -i for the body and dont use cat, mutt still opens its stuipd interactive mode. And it still creates a "sent" file in the home folder.  Linking /dev/null to /home/$USER/sent did not work.

echo "set copy = no" > ~/.muttrc

cat /home/ec2-user/sat/output.txt | mutt -s "Current Sat Results" EMAIL@gmail.com

CRON

Hand edit mode:

export EDITOR=vim
crontab -e



Easier:

crontab -
0 * * * * cat /home/ec2-user/sat/output.txt | mutt -s "Current Sat Results" EMAIL@gmail.com
