Subject: RE: wordlist progress report bug
I have not looked at the code, but could this be due to looking at the
'first' word of the file?
If I remember, the % if computed by how many rules have been completed, but
then adjusted based upon just how forward we are in the word file we are.
How would it behave, if it thought we were are line 0 (before the first line
was processed?) What would a single entry, and LOTS of rules, with a very
slow format do?
Here was a run with 1 pw, 1 ssh hash, and a large set of rules:
C:\phpbb\johnripper\john-1.7.9\jumbo-unstable\run>john -w=x.txt ssh.in
-conf=/c/phpbb/john.ini -rules=Wordlist_pre_post_big_list
Loaded 1 password hash (SSH [32/32])

Here is a rar run (again, only 1 word, many rules).

I would say, it appears that this has been a long standing bug, where the
wordfile is either 'before' the start, or 'after' the end.
