Last active August 29, 2015 14:06
Small python script to run update-alternatives (on Debian) or alternatives (on CentOS) for Oracle JDK's java and javac. Correctly updates all the man paths etc. Assumes JDKs are installed in /opt/java/ on Debian, or /usr/java/ on CentOS (which is where the RPMs install it).

OSX VPN Sharing (from https://davidhamann.de/2017/04/19/sharing-vpn-on-macos/)
#
# Default PF configuration file.
#
# This file contains the main ruleset, which gets automatically loaded
# at startup. PF will not be automatically enabled, however. Instead,
# each component which utilizes PF is responsible for enabling and disabling
# PF via -E and -X as documented in pfctl(8). That will ensure that PF
# is disabled only when the last enable reference is released.
#
# Care must be taken to ensure that the main ruleset does not get flushed,
