Why can't you manage one node from another?
I have 3 nodes in the cluster, and
bin/nodetool --host this-host-name ring
Works as expected, but
bin/nodetool --host some-other-host ring
always throws this exception:
Error connecting to remote JMX agent!

My hosts file looks like:
127.0.0.1 localhost
127.0.1.1 ec1
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
