Given: my local network is 10.1.1.0/24, my username is jabenninghoff, my ssh host is ssh.example.com, my host's address is 10.1.1.17, my ssh port is 22, and I'm connecting from either 10.1.1.33 (locally) or 172.16.1.20 (remotely)
When: connecting from the local network
Then: allow default ssh authentication methods

When: connecting from other networks
Then: require key-based authentication

Configure using a Match rule:

Match Address *,!10.1.1.*

By default, OS X only mounts external drives (USB, Firewire, Thunderbolt, etc.) when you log in, and unmounts them when you log out or reboot. To change this behavior, enable AutomountDisksWithoutUserLogin.

sudo defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin -bool true

Installing OS X Server also enables this setting.

Alternatively, you can create the /Library/Preferences/SystemConfiguration/autodiskmount.plist with the following content:

#!/bin/sh
# one-liner courtesy of http://zanshin.net/2014/02/03/how-to-list-brew-dependencies/
brew list | while read cask; do echo -n "$cask ->"; brew deps $cask | awk '{printf(" %s ", $0)}'; echo ""; done

macOS Sierra (and possibly earlier) has some "hidden" screen sharing options:

If you're connecting to VNC using ssh tunneling, you can force macOS to listen only on localhost:

sudo defaults write /Library/Preferences/com.apple.RemoteManagement.plist VNCOnlyLocalConnections -bool yes

In newer versions of macOS, screen sharing will automatically re-lock the screen when you disconnect if it was locked when you first connected. To change this behavior, use:

sudo defaults write /Library/Preferences/com.apple.RemoteManagement RestoreMachineState -bool NO

#!/bin/sh

set -ex

mkdir -p /tmp/repro-5346
cd /tmp/repro-5346

cat > Gemfile <<EOF
source 'https://rubygems.org'
require 'json'

Occasionally on older versions of OS X, connecting to a remote system via VNC will result in a "Black Screen" that is non-responsive. To fix this, kill the loginwindow process:

$ ps ax | grep loginwindow
   83   ??  Ss     0:00.89 /System/Library/CoreServices/loginwindow.app/Contents/MacOS/loginwindow console
$ sudo kill 83

loginwindow will automatically restart and the login screen will appear.

Thanks to Mac Mini World!

Graylog uses mongo:3 in its docker-compose image, which automatically pulls the latest production version of MongoDB, but does not set the feature compatibility version. This will cause databases created in 3.2 or earlier to fail to start in 3.6.

Per https://docs.mongodb.com/manual/reference/command/setFeatureCompatibilityVersion/, this will show the current running compatibility version and upgrade from 3.4 to 3.6:

docker exec -it mongo_container /bin/bash
mongo
db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )
db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } )
exit
exit
