Flexlnet 11.5 target

[rcer]

Ketan,

Thanks for this usefull info, but this target is .NET, and only the flexlm routines are machine code, and I don't have a clue how to debug NET.

[Git]

.NET program will often call FlexLM functions in an ordinary DLL.

use visual studio + reflector plugin

Also this tool is interesting for .NET "spy".

Git,

This is also the case with this target, but I don't have a clue how to debug a NET executable with VS & reflector

I'm pretty much sure flexnet api is either in the same binary PE section or in external dll.

Very simple way to get it debugged is patch any api call found (lc_new_job e.g) to int 3 and let system debugger catch it.

@nikkapedd - made my 1st flex target almost 20yrs ago, thanks you for insights though :-)

I am suggesting you debug the DLL if it is as I think. You could even debug both .NET program and normal DLL at the same time using reflector for the .NET and IDA for the DLL.

O.K. Looks like I will have to learn NET, and how to use reflector for debugging

Does anybody have a good tutorial about debugging an executable with refector?

Reflector is not the right tool to debug an net assembly, you can try the Dile or IlSpy to do this.

May be a stupid question: do you have a sample valid license file ? My guess is that you a re missing one of those strings that may be forced to be mandatory (NOTICE=, VENDOR_STRING=, ert ...)

Rcer-
Take a look at this post for debugging with .NET. I saw your post and reminded me of myself a few years back...
