Increasing fs.inotify.max_user_watches for Docker images

TL;DR You can't set those for an image during build time becasue Docker takes the sysctl configuration from the Host. So, set the config on your host machine.

As in this link, to increase the maximum watchers, we need set fs.inotify.max_user_watches to a higher number in /etc/sysctl.conf.

}

# reload daemon conf:
sudo systemctl reload docker.service

This gist describes how to add Anaconda Prompt to the Windows right click context menu. This is because at some point, Anaconda no longer adds itself to the PATH after installation.

1. Run regedit.exe
2. Navigate to HKEY_CLASSES_ROOT > Directory > Background > shell
3. Add a key named AnacondaPrompt and set its value to "Anaconda Prompt Here" (or anything you'd like it to appear as in the right click context menu)
4. Add a key under this key, called command, and set its value to cmd.exe /K C:\Anaconda3\Scripts\activate.bat (may have to change the activate.bat file to whereever Anaconda is installed)

pfSense Simple Home Configuration - 2.4.3 / 2.4.4

Starting from Scratch

This is my personal guide for installing pfSense. Hope you find it useful. I made these notes to capture the details of my "install from scratch" to ensure I didn't miss important details. Also, I'm trying build my network with discrete "disposable" components that make the system mutable and less rigid. It does not cover installing any packages like Squid or Suricata as that's way beyond the scope of a basic, functional install.

I migrated from an environment that was at various times running Tomato Toastman 1.28 or Asuswrt-Merlin on Netgear and ASUS routers across four "access points" (one always acting as the firewall/gateway, the rest as APs). It was OK pre-gigabit, but had roaming problems, and I was using large Wifi routers with most of the features disabled. Also, I found that I could easily swamp the network and tank VOIP and Wifi Calling without even trying. The only fix was to throttle everything by using Bandwidth Limit
