has anyone been able to get crack to run on Digital Unix?  I have it
working on the machines running SunOS but not the Digitals.  Thanks,

Yes, I did.
I compiled it long time ago, so I don't remember the details.
Send me a mail if you want me to send you the binaries.

Subject: [SUMMARY] Crack

Dear colleagues,

Some time ago I asked for the patches that would enable me to compile and
install Crack4.1 on a DU box. In my previous summary, I just stated that I
received them and that everything was fine ... which was really too short,
as indicated by the number of mails that I subsequently received.
Hence in this more complete summary I indicate clearly (I hope) how to
retreive the necessary patches.

Good luck!

Jean-Loup

---------------------------------------------------------

I have put the following files for Crack in my anonymous ftp server:

ftp://genome.genetique.uvsq.fr/pub/outgoing

1) the patch crack-4.1.Patch.OSF.Z that you should first apply to Crack.
   Put it in Crack-4.1/Sources, uncompress and
   "patch -i crack-4.1.Patch.OSF"

2) the file ufc-crypt.tar.Z.
   Put it in Crack-4.1, uncompress and untar  --> it will put the files in
   ufc-crypt/

3) the patch ufc.patch. Put it in the Crack directory and patch.

You can also find extra dictionaries everywhere on the net (try Archie
      dictionaries). They are all the same everywhere. I got them in
      France from ftp://ftp.ibp.fr/pub/unix/security/dictionaries, and put
      them in DictSrc. Crack will do what it must do with them, see its
      README file. Now my bigdict.Z file is about 2.5 Mbytes.... which may
      explain why Crack is VERY long to run: about 36 h to scan ca. 100
      passwords. Thus don't forget the -n option when launching Crack!
      Anyway Crack is very efficient and did crack passwords like
      "Castafio", "Crocotte", "Schillo", ....

2.5 Mb is small.  I have a 7Mb COMPRESSED bigdict file.

(if compressed with compress instead of gzip, it would be over 8MB)
However, a large part of it is Polish dictionary - not too useful for
users outside Poland.

Out of interest has anyone got Crack to working with Digital Unix's
Enhanced Security???  The problem is that with Enhanced security
passwords are not stored in /etc/passwd but in a separate tcb
authorization file for each user.

I know it would be quite easy to hand-roll a script to do this but if
someone has already done this I would be very grateful for a copy of what
was written.
