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?

doveadm-auth

DOVEADM-AUTH(1) 						      Dovecot							   DOVEADM-AUTH(1)

NAME

       doveadm-auth - Test authentication for a user

SYNOPSIS

       doveadm [-Dv] auth [-a auth_socket_path] [-x auth_info] user [password]

DESCRIPTION

       The auth command can be used to test the authentication for the given user.

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -v     Enables verbosity, including progress counter.

       Command specific options:

       -a auth_socket_path
	      This option is used to specify an absolute path to an alternative UNIX domain socket.

	      By  default  doveadm(1)  will use the socket /var/run/dovecot/auth-client.  The socket may be located in another directory, when the
	      default base_dir setting was overridden in /etc/dovecot/dovecot.conf.

       -x auth_info
	      auth_info specifies additional conditions for the auth command.  The auth_info option string has to be  given  as  name=value  pair.
	      For multiple conditions the -x option could be supplied multiple times.
	      Possible names for the auth_info are:

	      service
		     The service for which the authentication lookup should be tested.	The value may be the name of a service, commonly used with
		     Dovecot.  For example: imap, pop3 or smtp.

	      lip    The local IP address (server) for the test.

	      rip    The remote IP address (client) for the test.

	      lport  The local port, e.g. 143

	      rport  The remote port, e.g. 24567

ARGUMENTS

       user   The user's login name.  Depending on the configuration, the login name may be for example jane or john@example.com.

       password
	      Optionally the user's password.  doveadm(1) will prompt for the password, if none was given.

EXAMPLE

       This example demonstrates an imap authentication test for user john, assuming the user is connected from  the  host  with  the  IP  address
       192.0.2.143.

       doveadm auth -x service=imap -x rip=192.0.2.143 john johns_password
       passdb: john auth succeeded
       extra fields:
	 user=john
