Hi I have 2 node Cassandra cluster and each linux box configured with a firewall. The ports 7000, 7199 and 9160 are open in the firewall and I can telnet to the ports from both ends without any issue. But if I try to do a nodetool from one of the Cassandra node, it hangs and didn't print anything. $ sh nodetool -h app1 info Could someone please help me on this? Thanks. -- View this message in context: http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/nodetool-hangs-and-didn-t-print-anything-with-firewall-tp7257286p7257286.html Sent from the cassandra-user@incubator.apache.org mailing list archive at Nabble.com.
