Hi everybody!
My target is GC-Powerstation, it's proctection is Flexlm + Sentinel Dongle.
Flexlm uses LM_A_VENDOR_ID_DECLARE to change HOSTID to GC_DONGLE ID (ex. HOSTID=GC_DONGLE=1234 ).
If I make a license which HOSTID=ANY, the program can't pass.
How can I crack this target ?

An obvious method would be to patch the dongle on the program, and emulate it to a id, say 1234 - then make a license with the hostid emulated. I have seen stuff like that before, but useually without a sentinel this works:
HOSTID=SENTINEL_ID=0
due to the obvious hostid of 0 with no dongle connected.

Or, you can compile your Daemon ;-)
If you used the Daemon that gets built when you compile a new license generator, you get a demo daemon. Rename and use that as the apps daemon.
Worked for me.
PS - Dont forget to setup you license.dat file to correctly reflect the use of a Daemon.

Try to trace l_new_hostid routine.
