NAME

   doveadm-who - Show who is logged in to the Dovecot server

SYNOPSIS

   doveadm  [-Dv]  [-f  formatter]  who [-1] [-a anvil_socket_path] [user]
   [ip[/mask]]

DESCRIPTION

   The who command is used to  show  which  users  from  which  hosts  are
   currently connected to which service.

OPTIONS

   Global doveadm(1) options:

   -D     Enables verbosity and debug messages.

   -f formatter
          Specifies  the  formatter  for formatting the output.  Supported
          formatters are:

          flow   prints each line with key=value pairs.

          pager  prints each key: value pair on its own line and separates
                 records with form feed character (^L).

          tab    prints  a  table  header  followed by tab separated value
                 lines.

          table  prints a table header followed by adjusted value lines.

   -o setting=value
          Overrides       the       configuration       setting       from
          /etc/dovecot/dovecot.conf  and  from  the  userdb with the given
          value.  In order to override multiple settings,  the  -o  option
          may be specified multiple times.

   -v     Enables verbosity, including progress counter.

   This command uses by default the output formatter table.

   Command specific options:

   -1     Print   one   line  per  user  and  connection.   Otherwise  the
          connections are grouped by the username.

   -a anvil_socket_path
          This option is used  to  specify  an  alternative  socket.   The
          option's  argument  is  either  an absolute path to a local UNIX
          domain socket, or a hostname and port (hostname:port), in  order
          to connect a remote host via a TCP socket.

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

ARGUMENTS

   ip[/mask]
          Specify an ip address or network range,  in  CIDR  notation,  to
          reduce the result to matching connections.

   user   List  only  users, whose name match user.  It's also possible to
          use wildcards in the user name.
