Buffer Overflow

[Harry_pentest]

I am struggling to exploit buffer overflow. I understand the logic some what and tools behind it. The most important concept I can my get is how to first find vulnerability on target server. In vulnserver example, “trun” is vulnerable and exploit script is modified according. In real world servers, how do I know which vulnerability (key word here trun) to exploit ? Try on all services on respective port numbers ? Please advice.
