Hi All
Situation: I have FlexLm protected tool (under Linux). I have lic.file (but it doesn't work on my machine).
SERVER ......
FEATURE xxx vendor_d ... SIGN="xxxx xxxx...xxxx"
So, LM_STRENGTH_239BIT. FlexLm v.10.8.2.2 (linux version)
I made signuture ida-file for FlexLm v.10.8.2.2 & after analaizing vendor_d, I found l_pubkey_verify() & patch it to return 0.
After that I've generated my own lic.file (according to format & data of source lic.file
with own LM_SEEDs.
Ok, next I launched lmgrd -c my_lic.file, everething was ok.
Run my application & got no success. I've got messeges like: "unsupported feature" (althoug feature is in mylic.file), "doesn't support feature that version" and so on.
I've also patched l_checkout() to return 0. No success. Maybe vendor protect this app somehow else...
Gentlemen, any ideas? ;-)
