Yes Aaron, I am well aware of nmap and it's always one of the first
packages I install on distros if
they don't come with it when I'm installing 'network' packages.
[Note to you Aaron >>> remember the distros I have discussed with you in
the past Kali (migration of Backtrack) and Parrot
which come with a lot of network 'tools' and pen-testing options? They are
still around too.]


Thank you Aaron for your taking the time to list those resources ^^^
hopefully others will use them as well. I will have fun
perusing them...


John, whom I'm not sure if he is on this SF-LUG mailist and is newer to the
meet-ups, is running what he self-titles a 'security-oriented-box' with
mulitple distros running in vm's and one he is using is Qubes <
https://www.qubes-os.org/intro/>  && <https://en.wikipedia.org/wiki/Qubes_OS
>
which I had a discussion with him about since I had read some documentation
on it and was looking into it quite a while ago...


Thank you Aaron for your IMHO/IMNSHO contributions as well ;-))>
[Sidenote]
When I finally get the box with secure server software on it up and having
a home powered up 24/7-365 I definitely want to offer you a SSH login et
al..


And of course invite you to attack it >]> all you like...


Enjoy your weekend...


'maestro'


message ends.
