Thread: FlexLM 9.0 without license

    Question FlexLM 9.0 without license

    Greetings to all members,
    I have a software that is protected with FlexLM 9.0.

    I don't have a license so I have no idea what features should be there. Here is a log of configuration utility:

    Could you please help me, is it possible to make my own license.dat? Or are there any other ways to remove this protection?

    Also, I have a problem starting FlexLM service. It gives me error 1067 when I start it using control panel.

    Sorry for stupid questions, I know almost nothing on FlexLM...

    Thanks for your answer. I tried to use 'fake' license file with some features found on this forum. Daemon started, but I found "No features to serve" in log.

    As far as I can understand, I can get list of possible features from daemon.

    I upload license daemon, hope somebody can give me some advices on it: PGDAEM.zip

    Regards.

    from the vendor daemon file you can get Seed1/2. from main target software - the feature name and version.

    Thanks for fast and clear answer!

    All tutorials that I saw on the web (respect, CrackZ and others!) are dealing with 7.x or 8.x versions of FlexLM. What are the principal differences for 9.0?

    I extracted seeds from your daemon

    sample lic below

    -------
    SERVER hostname ANY
    VENDOR SIEMPGL
    FEATURE test1 SIEMPGL 1.0 permanent uncounted 748F626A247B HOSTID=ANY \
    ISSUER=RubberDuck
    FEATURE test2 SIEMPGL 1.0 permanent uncounted CF1E685C206F HOSTID=ANY \
    ISSUER=RubberDuck
    FEATURE kaboom SIEMPGL 1.0 permanent uncounted B7DAC79F5501 \
    HOSTID=ANY ISSUER=RubberDuck
    ----------

    if your target don't use long sign (ecc) you can generate lic and run it without patch.
    I promise that I have read the FAQ and tried to use the Search to answer my question.

    Thanks for your attention to this topic! How can I find out, does my target use ecc or not? And what should I do to find out list of possible features (I mean 'real' features that could be put in license file)?

    Features name of the program you can find in exe or dll files as text string, flm logs or other txt files in program dir. Sometimes program ask for particular feature when you try to run it without valid lic file.
    One of my target has all features encrypted in vendor string although there is no ecc I can't recover it's names.
    When you know feature name and you have valid lic crypter for your daemon you can prepare license with server line and try to run it. When program answer that SIGN2 is missing in your lic you have ecc protection. But ECC is not all. I also play with some targets which don't uses ECC but has some vendor specific strings in lic file and if you don't know it you can't prepare valid lic even if you have right seeds 1/2.

    I wrote this based on my experience with flm targets. Of course there are other ways to check your targer for ecc, vendor stuff in lic etc.

    Doctor2k, thanks for explanation. I have decompiled my target software (it is Java-based) and I found the following functions:
    public int[] getVendorKeys()
    public int[] getCroKeys()
    public int[] getEncryptionSeeds()

    How can I check, are these encryption seeds valid (they are shown as return (new int[] {0xXXXXXXXX, 0xXXXXXXXX})?

    Also I succeeded to find ALL possible features as string constants in one decompiled Java class! How can I make license file with these features?

    Thanks for support and valuable advices to all forum members!
