Hallo guys, i would like to ask a question.
i have 4 remote servers (A,B,C,D) with ubuntu system, only one server (A) have a public ip adresse, others are Vms (B,C,D)can only be accessed via Server A with ssh .
now i have installed cassandra on B,C,D as a cluster and installed opsCenter on B. I want access the Opscenter on B with my local computer, so i did this. a port forwarding between local 8888 to B 8888 via remote server A.
ssh -L 8888:B server :8888 username@Aserver, but i can't open http://127.0.0.1:8888
buy if i do ssh -L 9160:B server :9160 username@Aserver, i can get access to the cassandra node on B witch cassandra-cli, connect to 127.0.0.1/9160.
did i missed something in config file or the opscenter doesn't work in this way? ps, i do not have root access on server A.
i will be very appreciate if some one give me a advise how can i achieve this. thank you ~^_^
