ssh connects to originating host

[Shashank]

See your issue?
No matter who (m?) you try to nslookup, it returns the same IP address:
63.251.179.5

Can you provide cat /etc/nsswitch output? Please provide this output
on both system A and B.

Specifically we are looking for the following entry:

hosts:      files dns   (Your file may have it in reverse order, if it
does please change it to look like what I posted and then try again)
