Hi Ra=C3=BAl,

=C2=A0 I tried the command you suggested and I am not getting any respons=
e. I tried the same command for the port 2181=C2=A0and that is bound to z=
ookeeper, this was the result for port 2181

tcp6 =C2=A0 =C2=A0 =C2=A0 0 =C2=A0 =C2=A0 =C2=A00 :::2181 =C2=A0 =C2=A0 =C2=
=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 :::* =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=
=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0LISTEN =C2=A0 =C2=A0 =C2=A00 =C2=A0=
 =C2=A0 =C2=A0 =C2=A0 =C2=A063007 =C2=A0 =C2=A0 =C2=A0 6778/java

=C2=A0 Does this means zookeeper is not bound to the port 3888=3F The onl=
y place where I have mentioned port 3888 is in the config file at server.=
1=3Dx.x.x.x:2888:3888. Should I make other configuration changes=3F=C2=A0=

HI Rahul, =20
