# Part one of a quick and dirty script
# to get a cowrie SSH honeypot up and running

# This one just changes the SSH port, the
# good stuff happens in the Part two :)

# Init the actual SSH port we will use to
# access the real honeypot server, not the
# cowrie SSH instance
SSHPORT = 1122

# Yes, this needs to run as root.

# Freshen up for the onslaught! Standard Ubuntu update.
apt-get update
sudo apt-get -y upgrade

# Change the SSH daemon port from 22 to something obscure, like... 1122
sed -i 's/Port 22/Port $SSHPORT/g' /etc/ssh/sshd_config
service ssh restart

# Tell the user to reconnect now!!
