hi szy111

depend on flexlm version and its behaviour there are more than one l_string_key. if your question is that you set breakpoint but programs not break, the answer is you must set breakpoint in every of them.

find your target flexlm version with lmtools then open target in olly and scan object file with lmgr.lib or lmgrd.lib and then set breakpoint on every l_string_key. in middle of everyl_string_key you will see 2 call to signed32.

sorry, my mean is that i can not find l_string_key breakpoint in my target, it report symbol not found !!!

my target is unix program , not win'program , so can not use olly .

hi szy111

MOV DWORD PTR SS:[EBP-0B0],8
MOV DWORD PTR SS:[EBP-114],5
MOV DWORD PTR SS:[EBP-20],0A

hi toro:
thank you again. i know the vendor name , but it is my first target for crack on win. so i rename it to test . i will set breakpoint at l_string_key , then trace in and watch the value at the adress where call 424410 , it maybe seeds. right? i got the value 00a1b3e8 and 00a19ee8 , it's wrong !!!
