System parameters on server neo03

####
#
# /etc/sysctl.conf is meant for local sysctl settings
#
# sysctl reads settings from the following locations:
#   /boot/sysctl.conf-
#   /lib/sysctl.d/*.conf
#   /usr/lib/sysctl.d/*.conf
#   /usr/local/lib/sysctl.d/*.conf
#   /etc/sysctl.d/*.conf
#   /run/sysctl.d/*.conf
#   /etc/sysctl.conf
#
# To disable or override a distribution provided file just place a
# file with the same name in /etc/sysctl.d/
#
# See sysctl.conf(5), sysctl.d(5) and sysctl(8) for more information
