Missing dependencies in Attacker Server

[1ncludeSteven]

Describe the bug Missing two dependencies in Attack Search:

• missing pip dependencies of aiosmptd when updating tests after switching from smptd to aiosmtpd in Attacker
• missing systemd-resolved apt in Attacker Server so that the /run/systemd/resolv/resolv.conf is not exist

To Reproduce For the first missing dependency: running /usr/bin/python3 /usr/bin/external_mail_handler.py, then the failure is as below: And after install python3-aiosmtpd, we can running /usr/bin/python3 /usr/bin/external_mail_handler.py successfully, however, the service still can not running successfully with error as below:

For the second: running ls /run/systemd/, the result doesn't have a directory named resolv

Expected behavior

• install python3-aiosmtpd in Attacker using apt, and change the input('SMTP server running. Press Return to stop server and exit.') to below code:

  try:
      while True:
          pass  # keep running
  except KeyboardInterrupt:
      self.controller.stop()

• install systemd-resolved after attacker is installed using apt

Yup, missed that when switching from the deprecated smtpd module.
