DOVEADM-PW(1)							      Dovecot							     DOVEADM-PW(1)

NAME

       doveadm-pw - Dovecot's password hash generator

SYNOPSIS

       doveadm [-Dv] pw -l
       doveadm [-Dv] pw [-p password] [-r rounds] [-s scheme] [-u user] [-V]
       doveadm [-Dv] pw -t hash [-p password] [-u user]

DESCRIPTION

       doveadm pw is used to generate password hashes for different password schemes and optionally verify the generated hash.

       All  generated  password  hashes  have  a {scheme} prefix, for example {SHA512-CRYPT.HEX}.  All passdbs have a default scheme for passwords
       stored without the {scheme} prefix.  The default scheme can be overridden by storing the password with the scheme prefix.

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -v     Enables verbosity, including progress counter.

       Command specific options:

       -l     List all supported password schemes and exit successfully.
	      There are up to three optional password schemes: BLF-CRYPT (Blowfish  crypt),  SHA256-CRYPT and  SHA512-CRYPT.   Their  availability
	      depends on the system's currently used libc.

       -p password
	      The  plain  text password for which the hash should be generated.  If no password was given doveadm(1) will prompt interactively for
	      one.

       -r rounds
	      The password schemes BLF-CRYPT, SHA256-CRYPT and SHA512-CRYPT supports a variable number of encryption rounds.  The following  table
	      shows  the  minimum/maximum number of encryption rounds per scheme.  When the -r option was omitted the default number of encryption
	      rounds will be applied.

	       Scheme	    | Minimum | Maximum   | Default
	      ----------------------------------------------
	       BLF-CRYPT    |	    4 |        31 |	  5
	       SHA256-CRYPT |	 1000 | 999999999 |    5000
	       SHA512-CRYPT |	 1000 | 999999999 |    5000

       -s scheme
	      The password scheme which should be used to generate the hashed password.  By default the CRAM-MD5 scheme will be used.  It is  also
	      possible to append an encoding suffix to the scheme.  Supported encoding suffixes are: .b64, .base64 and .hex.
	      See also http://wiki2.dovecot.org/Authentication/PasswordSchemes for more details about password schemes.

       -t hash
	      Test  if	the  given  password hash matches a given plain text password.	The plain text password may be passed using the -p option.
	      When no password was specified, doveadm(1) will prompt interactively for one.

       -u user
	      When the DIGEST-MD5 scheme is used, also the user name must be given, because the user name is a part of the  generated  hash.   For
	      more information about Digest-MD5 please read also: http://wiki2.dovecot.org/Authentication/Mechanisms/DigestMD5

       -V     When  this option is given, the hashed password will be internally verified.  The result of the verification will be shown after the
	      hashed password, enclosed in parenthesis.

EXAMPLE

       The first password hash is a DIGEST-MD5 hash for jane.roe@example.com.  The second password hash is  a  CRAM-MD5  hash  for  john.doe@exam-
       ple.com.

       doveadm pw -s digest-md5 -u jane.roe@example.com
       Enter new password:
       Retype new password:
       {DIGEST-MD5}9b9dcb4466233a9307bbc33708dffda0
       doveadm pw
       Enter new password:
       Retype new password:
       {CRAM-MD5}913331d8782236a8ecba7764a63aa27b26437fd40ca878d887f11d81245c2c6b

NAME

       doveadm-log - Locate, test or reopen Dovecot's log files

SYNOPSIS

       doveadm [-Dv] log errors [-s min_timestamp]
       doveadm [-Dv] log find [directory]
       doveadm [-Dv] log reopen
       doveadm [-Dv] log test

DESCRIPTION

       The  doveadm  log commands are used to locate and reopen the log files of dovecot(1).  It's also possible to test the configured targets of
       the *log_path settings.

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -v     Enables verbosity, including progress counter.

COMMANDS

   log errors
       doveadm log errors [-s min_timestamp]

       The log errors command is used to show the last	- up to 1,000 - errors and warnings.  If no output is generated, no errors  have  occurred
       since the last start.

       -s min_timestamp
	      An  integer  value, representing seconds since the epoch - also known as Unix timestamp.	When a min_timestamp was given, doveadm(1)
	      will only show errors occurred since that point in time.

   log find
       doveadm log find [directory]

       The log find command is used to show the location of the log files, to which dovecot(1) sends its log messages.	 If  dovecot(1)  logs  its
       messages  through  syslogd(8)  and doveadm(1) could not find any log files, you can specify the directory where your syslogd writes its log
       files.

   log reopen
       doveadm log reopen

       This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings.  These settings
       are configured in /etc/dovecot/conf.d/10-logging.conf.
       This is for example useful after manually rotating the log files.

   log test
       doveadm log test

       This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files.  The used prior-
       ities are: debug, info, warning, error and fatal.

EXAMPLE

       This example shows how to locate the log files used by dovecot(1).

       doveadm log find
       Looking for log files from /var/log
       Debug: /var/log/dovecot.debug
       Info: /var/log/mail.log
       Warning: /var/log/mail.log
       Error: /var/log/mail.log
       Fatal: /var/log/mail.log
