[pwn] You know 0xDiablos

Can you post a link to some good tutorials on bof-ing?

I see both functions in g**ra and I love how params form words in hex :), but I don’t know the basics I guess, as payload I’m creating does nothing.
Shall I just fill the whole 384 reserved bytes and put params and f
ag function adrress just after it? Or maybe if I just put any string delimiter and some sort of JMP or call just after?
