Found a troubling result of the following and figured someone might want to take a look.
Pay close attention to the output and behavior. sysctl net.inet.udp.blackhole=0 sysctl net.inet.udp.blackhole sysctl -d net.inet.udp.blackhole=1 sysctl net.inet.udp.blackhole Is this expected ? should it not just display the description instead of adjusting ? as well not display the description like it is adjusting the description too ? # sysctl net.inet.udp.blackhole=0 net.inet.udp.blackhole: 0 -> 0 # sysctl net.inet.udp.blackhole net.inet.udp.blackhole: 0 # sysctl -d net.inet.udp.blackhole=1 net.inet.udp.blackhole: Do not send port unreachables for refused connects -> Do not send port unreachables for refused connects # sysctl net.inet.udp.blackhole net.inet.udp.blackhole: 1
