Hi --
I tried to implement this program (Crack) on a DU machine with C2
Security enabled, running as root. Unfortunately, it does not seem to
be referring to the files in /tcb/files/auth/* for the users passwords
as I'd like to be able to scan users who have easy guessable
passwords.
Has anyone created a modification so Crack can work with those
shadowed files? If so, then I'd appreciate some feedback.
Thanks!
Jon

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!

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", ....
