unable to connect DR node thru putty
 

We have couple of linux boxes with version 6.8. Few are at Primary and other few are at DR site. When we make SSH connection(thru putty) from Primary site linux box to a specific DR node, the SSH connection become established. However after login we are unable to run commands and session got hanged.

However this is not the case when we make SSH connection (thru putty) from any DR node to that specific DR node. Means connection become established. Seems a Network issue. How can we verify this ?

Going to try to help here with a couple of questions:
1. What do you mean by "specific DR node"?
2. For that matter, what do you mean by DR?
3. "make SSH connection (thru putty) from primary site box to 'specific DR node' doesn't make sense. PuTTY is a windows application. Are your primary site boxes Windows?

Please clarify.

A specific node at DR machine has issue(Linux BOX)
Machine exist at DR site premises
From a windows base machine as well as linux based machine when we make SSH connection to a DR machine(Linux BOX) we faces hanged problem

..and since all you say is "Linux BOX", what exactly do you think we can tell you?? Version/distro of Linux? SSH? Error(s)/message(s) from running the SSH connection in debug mode? Logs from the DR system?? Just saying "Linux BOX" and 'faces hanged problem', tells us nothing.

What do you mean by DR??!!!

If a "Linux BOX" is "hanging" when you connect to it we'd need to know several things:
What distro is it running?
What actually happens when you try to connect? Paste the command and result in [code] tags.
Do you have a way to look at the logs on the remote server?
