Description

when I do unit test on mac os for cassandra4.0 tag version , I found that the unit test failed when doing MessagingServiceTest on method listenRequiredSecureConnectionWithBroadcastAddr.

I found out that it is because that the mac os can not get connect to ip address 127.0.0.2 on default.
so when you doing : ant test -Dtest.name=MessagingServiceTest -Dtest.methods=listenRequiredSecureConnectionWithBroadcastAddr

you can get a bind exception : can not assign request address.

what to do with it ,you can just set the 127.0.0.2 by :
sudo ifconfig lo0 alias 127.0.0.2 netmask 0xFFFFFFFF

then the unit can run successfully .
