failed to connect to cloudera EDH on AWS via ssh tunnel in Putty

Hello there,

I am fairly new with unix command. Could someone help me with this?

I was trying to ssh into my cloudera EDH instance, following the instruction here. I think I got the ssh established to port 7189. However, I still cannot connect to cloudera manager from my local browser, and it gives me 'refuse to connect' error.

I am running Putty on a windows machine. here is the putty log:

[ec2-user@ip-172-31-10-233 ~]$ ssh -i /home/ec2-user/cloudera/setup-default/main_key.pem -L 7189:localhost:7189 ec2-user@ec2-35-182-66-141.ca-central-1.compute.amazonaws.com

process 4203 is already running, I assume that is the ssh tunnel i just created? but i still cannot access to http://localhost:7189/ on chrome nor firefox. What is the issue here?

thank you so much for the help.

found the solution.

1) port forwarding should be defined in the PuTTy interface: ssh ->auth->tunneling

2) need to enable the inbound rule to include TCP traffic
