Terrform configuration for gophsih/postfix stmp server on multiple providers FILE cloud_init.cfg

1. Libvirt - localhost
2. AWS
3. Azure
4. Civo

Aim is to spin up bare servers and use cloud_init.cfg for identical config across all providers.

Instructions for localhost deployment of gohpish/postfix

1. Set instance and resource variables in variables.tf ESPECIALLY THE CLOUD INIT FILE cloud_init.cfg in main.tf line 10
2. Run the following:

terraform init
terraform plan
terraform apply

in localhost to get IPs (may take up to 30 seconds before IPs come up):

virsh net-dhcp-leases ${VM_HOSTNAME}_network

ssh into VMs

ssh ${VM_USER}@ip_address

check postfix installed (plus other services)

service --status-all

to get cloud-init build log (check for error messages in build)

sudo tail cloud-init.log

to get gophish initial password when running cloud_init.cfg

cd /var/log sudo tail -n 200 cloud-init-output.log

to check postfix mail log

cd /var/log sudo tail mail.log

access gophish on libvirt(localhost)

get ip address (e.g. 10.10.10.179) and call 'https://:3333' in browser

to send test email with gmail as the final relay from gophish, setup the following in cloud_init.cfg (currently at line 30), ensure the gmail account you use has less_secure apps enabled. The format is user:password for gmail.

write_files:

- path: /etc/postfix/sasl_passwd
  content: |
  [smtp.gmail.com]:587 gmail_username:gmail_password
  owner: root:root
  permissions: 0400

In the sending profile at '/sending_profiles' fill in:

Name <profile name, can be anything> From Host: localhost: 25

You can leave the other fields blank. Send a test email to your own email address, you should receive an email with subject 'Default Email from Gophish'. This demonstrates that you are sending an email through postfix (localhost:25) to smtp.gmail.com, and then on to your mailbox.

Issues can be tracked in the logs referenced above.

exit then run

terraform destroy
