chore: add a vagrant config to spin multiple vms

[bruno-fs]

QoL for development. Easily spin multiple vms to run network scans locally.

My personal cheat sheet for vagrant:

# spin all vms
vagrant up
# get the ips
vagrant ssh-config | grep HostName | awk '{print $2}'
# tear everything down
vagrant destroy -f

[bruno-fs]

Ah, the oneliner for grabbing IPs might not be enough depending on provider.
You might need to grab port too.

LGTM 👍

I took this branch for a test drive, and your Vagrantfile mostly works for me!

The RHEL6 VM encountered an error running systemctl, and when everything was up, I wasn't able to SSH into the RHEL6 VM, but I didn't spend any time troubleshooting it. Is RHEL6 too old for the systemctl command? Did the RHEL6 VM setup work for you? Maybe I need to add a local ~/.ssh/config to allow the old weak ssh-rsa.

I successfully SSHed into all the other VMs, though! 🎉 I needed to include the port numbers when grepping the ssh-config like this:

vagrant ssh-config 2>/dev/null | grep -e '^Host\|\sHostName\|\sPort'

It is. service is there for RHEL6 (the error message can be safely ignored).

yup, it works, but I had to enable support for less secure kex algorithms

because this is so frequent (testlab running rhel6, ec2 running rhel6), I added to all my hosts on ~/.ssh/config

Host *
   HostkeyAlgorithms +ssh-rsa
   PubkeyAcceptedAlgorithms +ssh-rsa
   KexAlgorithms +diffie-hellman-group1-sha1

This is virtually what we have on discovery by enabling legacy compatibility

	# set cryptographic policy to a mode compatible with older systems (like RHEL5&6)
	RUN update-crypto-policies --set LEGACY
