Subject: john 1.4.2 with jumbo patch 1 - lm hash problem

Hi,

I just downloaded and compiled john 1.4.2 and jumbo patch 1.  I am running john against my test hash.txt and should take about 5 seconds to complete.  john has been going at my hashes for 30 minutes so far.  Something is very wrong.  I am testing the lm hash.  My PC is a P3 so I compiled john with make linux-x86-mmx.

# ./john /root/hash.txt
Loaded 6 password hashes with no different salts (LM DES [64/64 BS MMX])
BB               (b)
A                  (a)
TESTTES    (Administrator:1)
CDC             (c)
DEDE          (d)

# cat /root/hash.txt
Administrator:500:CEEB0FA9F240C200417EAF40CFAC29C3:D280553F0103F2E643406517296E7582:::

The administrator LM password should be TESTTEST.  The NTLM password is TestTest.  The NTLM crack works as it should.

Also I used to use john -f:nt hash.txt to tell john to use the NTLM algorithm.  In 1.4.2 I have to use john --format:nt hash.txt.  Is this change on purpose?

Thanks,
