How to setup secondary name server

[surety]

for anyone using a non standard ssh port...

on my centos 6.5 i had to make one small change to make this work because i have ssh listening on a non-standard port.

in the named-fetch-slave-zones.sh i had to change
/usr/bin/rsync -e ssh root@MASTER-SERVER-IP:/root/named_slave_zones_transfer/named.conf.slave.zones .
to...
/usr/bin/rsync -e "ssh -p ####" root@MASTER-SERVER-IP:/root/named_slave_zones_transfer/named.conf.slave.zones .
