I'm trying to crack a flexlm vendor daemon.
So far I've been loading in the vendor daemon directly into Olly with the following arguments

vendor_daemon -z -c licensefile

However, using this approach, the vendor daemon will check the licensefile but exits at the end. I need to have lmgrd call the vendor daemon. Additionally, I want to setup Olly such that when the client does a feature checkout request, I want Olly to break at the entry point.

I tried launching lmgrd -c licensefile but when I use Olly to attach to the running vendor daemon, Olly seems to capture the daemon in a system call and it never goes back to the vendor code.

Any tips on how to do this?

Thanks

PS: I realized that this may just as much a question about howto setup Ollydbg as well. Moderator, please move this post to the relevant forum if you feel it necessary.

Use following arguments:

"vendor daemon -T hostname 7.2* -1 -c c:\path\license.lic"

*version of your lmgrd


See your inbox, mate!

Thanks. That was really helpful.

Is the correct syntax " vendor daemon -T lmgrd version -1 -c c:\path\license.lic" ?
