John the ripper

Hi evryone,

I have problem the john program. It works correctly but I can not make unshadow command because I have removed the file /usr/bin/john by mistake

Code:

[root@localhost src]# cd ../run
[root@localhost run]# ./john /root/shadow
Loaded 2 password hashes with 2 different salts (FreeBSD MD5 [32/32])
letmein          (root)
letmein          (joe)
guesses: 2  time: 0:00:00:00 100% (2)  c/s: 6579  trying: letmein

Then I removed /usr/bin/john, I could do shadow:

Code:

[root@localhost run]# ./john /root/shadow
No password hashes loaded
[root@localhost run]# umask 077
[root@localhost run]# unshadow /etc/passwd /etc/shadow > mypasswd2
bash: unshadow: command not found
[root@localhost ~]# which john
/usr/bin/which: no john in (/usr/lib/qt-3.3/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/root/bin)
You have mail in /var/spool/mail/root
[root@localhost ~]#

So could you help and advise me what should I do?

NAME

       unafs - script to warn users about their weak passwords

SYNOPSIS

       unafs password-files cell-name

DESCRIPTION

       This  manual  page  documents  briefly  the  unafs command, which is part of the john package.  This manual page was written for the Debian
       GNU/Linux distribution because the original program does not have a manual page.  john, better known as John the Ripper, is a tool to  find
       weak passwords of users in a server.
       The unafs tool gets password hashes out of the binary AFS database, and produces a file usable by John.

SEE ALSO

       john(8), mailer(8), unique(8), unshadow(8).

       The programs are documented fully by John's documentation, which should be available in /usr/share/doc/john or other location, depending on
       your system.
