We start with ${KARAF_HOME}/bin/start clean [For background mode]
*Java Version*
$ java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
*No IPTables: {no blocker}*
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)
