Docker and IP-Tables

Over the weekend I got attacked. I realized the cause of this was because I rebooted my server and the docker IPTables rules overwrote the IPTables-Persistent rules I had. After realizing this was the case I uninstalled docker since I wasn’t using it and while I was making firewall changes I set up ipset to block most foreign countries. I also removed IPTables-Persistent and instead just added the post up to the /etc/network/interfacespost-up ipset restore < /etc/iptables/ipset.

Install KodExplorer

How I installed KodExplorer. This is running on Debian 8.1. Things might be different on whatever OS/Version you’re running. I am by no means a pro. This is pieced together from everything I’ve learned. You first have to install nginx and php apt install ngnix php5-fpm git if it’s a newer version of debian or ubuntu you might have to run apt install php7-fpm mkdir -p /etc/nginx/ssl/site.com cd /etc/nginx/ssl/site.com Fill out the info the next step asks.

Below is the config block that I added to a file. This make NGINX return a 403 error when accessing the server via IP or an reconfigured domain.

Over the past couple days I’ve been trying to get a Cisco 3560 with VLANs to work. Finally I was able to get it working. This is my first blog post FYI it’s not the most detailed. It’s just info on what I’ve learned. This is not the best post to read if you have no technical knowledge. If you have some you should be able to work your way thru my horrible instructions.
