Analyze traffic between multiple ssh hops in a ssh chain












0















The test case is as follows:



(Host A) ---ssh---> (Host B) ---ssh---> (Host C)



When Host A connects to Host B, Host B transparently connects to Host C.



The test case is working well.
This architecture is made using chaining method, editing $HOME/.bashrc in Host B to auto connect to host C.



I am making a project where I need to execute some scripts based on the commands Host A execute on Host C.



My problem is how can I "sniff" the commands on Host B, executed by Host A on Host C. I want to capture all the commands on the fly on Host B and make some decisions based on the commands executed.
