doveadm-who
DOVEADM-WHO(1) Dovecot DOVEADM-WHO(1)
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.
-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.
EXAMPLE
Show authenticated sessions, filtered by the client's IP address.
doveadm who ::1
username # proto (pids) (ips)
jane 2 imap (30155 30412) (::1)
doveadm who 192.0.2.0/24
username # proto (pids) (ips)
john@example.com 1 imap (30257) (192.0.2.34)
