    Hello,

    I have been watching episodes in the "Practical Pentesting: featuring Brad Stine" series. Brad has displayed several slides. Are there plans to have the slides / notes added to the associated files for the episodes or sometimes they are all added to the intro episode for the whole series?

    Thank you.

    I'm Watching this course and love it. I have seen a few courses where Don P. mentions Solar Winds & MRTG as 3rd party monitoring solutions. I was wondering why PRTG from the German Paessler is never mentioned. I have been using it for more then a decade and find it a great solution for third party monitoring to fill in the gaps that AWS CloudWatch lacks. Has anyone else used PRTG from Paessler AG?

    Question for Mr. Daniel Lowrie,

    I am very thankful for him putting together this series. For cases where client keys are generated for each user, and a user leaves the organization, how are they keys they may still have be revoked on the server side?

    btw, I have been fighting for the past few days with the /etc/sysconfig/docker OPTIONS directive.

    Anytime I add the -H tcp://0.0.0.0:2375 and start docker, there are the below msgs in journalctl and when I try to run a docker command, I get the response "cannot connect to the Docker daemon. Is the docker daemon running on this host?".

    Shutting down firewalld doesn't solve the problem.

    I also tried adding the below two commands with firewalld running and it too did not solve the problem.
    sudo firewall-cmd --zone=public --add-port=2375/tcp
    sudo firewall-cmd --zone-public --add-port=2375/tcp --permanent

    Any help would be appreciated. I have docker on a RHEL 7.4 host. Google searches have been inconclusive so far.

    Hello,

    The series ends with Linux as a Docker Host and there is mention that there will be a subsequent episode with a walk through on how to spin up docker containers. I do not see anything on the Google Calendar for this subsequent episode to be recorded and wanted to ask if it is still scheduled to be added.

    BTW, I like this content very much and have been taking notes for my own edification and enjoying doing so.

    Thanks.

    -Walter Schulze

    question. what are the pros/cons to using systemctl vs. the scripts in /etc/init.d/ ?

    Thank you. I love this course and the previous one "Becoming a Linux Power User". Great stuff!
