I am using bettercap command line to perform a Man in the Middle attack on my LAN network with an EDUCATIONAL purpose (of course!).
I want to intercept the TCP traffic, with the intention to view on my terminal the TLS certificate,public key etc. When I want to enable the TCP proxy by typing: bettercap -T [ip addr of a host in my network] --tcp-proxy
, I get an error message which says: No TCP proxy upstream server specified (--tcp-proxy-upstream-address ADDRESS).
What is a TCP proxy upstream server and where do I find its address?
Thank you so much if you would help me with this issue.
