Flexlm Stepped Walkthrough

[darsy]

Hi Kometata,

This is old very old daemon. Try to find seeds in default folder of flexlm:

C:\flexlm\...

Put your daemon.exe, lic.lic and olly or w32dasm files in same folder and load your daemon with standard Parametars:

Daemon.exe -T Z -4 c:\flexlm\lic.lic

I'm not sure i think this is syntax. The best way read Git papers for e. s. generation....

;-)

Hi Darsy,
Thanks for your comments!

Yes, I know that the bruker is old but I am trying to learn the approach before to try the real target, SC..HR..OD, if it is possible at all. I have some questions.
I extracted the seeds from the bruker_ls example by Olly and the Flexlm Seedfinder 7.2+. However, I was able to do that if I only use this option:

-app -T this_host 4 -z -c c:\flexlm\license.dat

if I use "-t this_host -c c:\flexlm\license.dat", which seems to be "standard" it not works. On the other hand, the bruker_ls is version 9.5 but when I tried M..O..E 2009, which is version 9.2, this approach not works. Thus I released that both the option and the dummy license is an important factor.
Thus if for the bruker_ls the dummy license was:

SERVER this_host ANY 001A92E2313F 1700
DAEMON bruker_ls C:\Bruker\bruker_ls.exe
USE_SERVER
FEATURE TOPSPIN2 bruker_ls 0.0 7-aug-2024 50 AB9E40017F6C081A44CC
FEATURE TOPSPIN_1D bruker_ls 0.0 7-aug-2024 50 EB1E20C1A1F0A2A1D348
FEATURE TOPSPIN_2D bruker_ls 0.0 7-aug-2024 50 CBFE3091A6FDA2A4C645
FEATURE XWINPLOT bruker_ls 0.0 7-aug-2024 50 BB8EC01158E130B13522

what would be for this case? :

FEATURE m..o..e ch..em..com..pd 2010.12 31-dec-2025 uncounted F782780B5A27 \
HOSTID=ANY ISSUER=Lz0 TS_OK

or mainly in this difficult case?:

Do you know also whether Flexlm Seedfinder works for version up to 11.11 or it should be rewritten?

I tried also your nice video tutorial with W32dsm but the daemon always crash, with above message, as in olley .
Can you please help a bit and guide me how to proceed and where is my mistake ?
I hope that this will be helpful for the other beginners too because above mentioned old materials are really old and difficult to understand, not as yours nice video!

EDIT1: Ok, I extracted the seeds also from M..O..E 2010 (hope to be correct) by this dummy lic:

SERVER this_host ANY BCAEC53CDE00 1700
DAEMON che..mco...mpd C:\Bruker\chemcompd.exe
USE_SERVER
FEATURE m..o..e che...mco...mpd 2010.12 31-dec-2045 uncounted AB9E40017F6C \

and -T localhost -11 -c c:\flexlm\license.dat

but not from the new one with SING ...

m..o..e che...mco...mpd 2012.10 31-dec-2099 uncounted HOSTID=DEMO TS_OK \
SIGN="03A9 99A7 4338 992E E1F2 BD2D 4CF4 A6D6 4B13 74FE 3603 \
2A50 0F9D 8435 EA6D B85C E35B 046E 0A7A 7937 3E02"

Above give me the error No features to serve, existing
existing due to signal 27 Exit reason 4

I will try also by W32dsm using your approach.

P.S. For those interesting I attach the seedfinder that can be at least used as a ground for feature improvements.

kometata, if you apply manually the script with olly or ida, you can recover easly the seeds to any target x86 and x64.. For shrodinger, try to patch the ecc and the buiild your customized vendor...

[kometata]

Thanks istigatore! I supposed that the customized vendor is the only elegant solution.I will be tankful if you guide me with some advices! Do you think that after creating the customized vendor it is trivial to inject the new pubkey or it will be no so easy? I mean that in shrodinger the pubkey is present in an available/visible form and it looks trivial. I am also a bit worry and about the long vendor info (here is a bit foggy for me) or you think this is not the problem?
And finally, I was not able to extract the seeds from shrodinger, this is not important for the discussed case but just wonder. Did you extract the seeds from shrodinger?

[istigatore]

The last edition of the schrodinger vendor is not obfucated.. So You can easly fish the seeds.. I done this job in less than 4 minutes with olly and ida.. And i made my customized vendor..
The long "vendor_info" is the only problem with schodinger.. And you can easly patch the check instead to waiste time to recover or change the pubkey in the dll...

[darsy]

Hi
It's not need to recovery encryptions seeds for schrodinger.
You can see in your lic file is only sign/sign2 key. Standard key 12 or longkey 20 long code is missed.
Sign key is generated with cro/trl keys only and standard key with encryption seeds only.
You need to build your lmcrypt with any encryption seeds and your vendor code can you also generate with
Vedor key generator 3.0 from zementmischer. Thats all.
After that you need to patch your target files and vendor daemon.
Public key ( vendor info keys) and also l_pubkey_verify (flexnet standard check for sign keys)

[istigatore]

darcy, you wrong..!!!! If you want inject your pubkey or make a standard license, by patching the 2 flags, you need to recover the encryption seed...!!!!!!!!!
Only if you patch the ecc, you can make a fake vendor.. But for this target(schrodinger) is not enough because it have the long "vendor_info"..

[kometata]

And you can easly patch the check instead to waiste time to recover or change the pubkey in the dll...

Hi all, by patch the check you mean that I will not need of any license?
I ask because my problem are the new features that missing in the old generated licenses..

[istigatore]

If you patch the ckeck, the license will be valid with any "vendor_info" filling...!!!!!
To use the program without license you need to patch the ckeckout verify...

[kometata]

If you patch the ckeck, the license will be valid with any "vendor_info" filling...!!!!!

By ckeck you mean the check function or the lictest.exe file? And what about SING's? Can I ask you or someone else to send me the lictest patched file for some version Please? I am not asking you to make me solution or for tutorial, just the file to find out/learn myself how to do that?

Thanks in advance!
