thanks guys & sorry for delayed response, as I was away. But this is not I am looking for, what I need is something like below :

Code:
<some_command>  <source-ip> <destination-ip>

This should give me the list of all open ports between two systems, we are using red hat linux 6.10 ( Santiago ), please help if at all this is possible to achieve.

Such command does not exist, or else someone would suggest it.

Maybe you will be happy on Linux with this:

Code:
netstat -an | grep 'your.remote.ip.address'

... for starters... and you can process the text further as you like?

Code:
ss state established src 192.168.122.1 dst 192.168.122.84
Netid           Recv-Q           Send-Q                       Local Address:Port                          Peer Address:Port           
tcp             0                0                            192.168.122.1:45376                       192.168.122.84:ssh

I set two goals and look at all the established connections. What is the problem?
I have one established SSH connection, there are no other connections! That's all.
It is incorrect to apply the concepts of source and destination and open ports to two machines without any connection

Isn't it possible to use concept of telnet from source server & some sort of querying where it scans all ports one by one & gives the output ?
Or may be some port scanning tool ?

I already provided a link to scanning tools which will do this kind of port scanning.

Please read the posts and review the links and/code we provide you.
