current-time   The current local time in the form "DDD MMM dd hh:mm:ss
                    YYYY", where DDD is the day of the week, MMM is the month,
                    dd is the day of the month, hh is the hour, mm is the min-
                    utes, ss is the seconds, and YYYY is the year.

transfer-time  The total time of the transfer in seconds.

remote-host    The remote host name.

byte-count     The amount of transferred bytes.

filename            The canonicalized (all symbolic links are resolved) abso-
                    lute pathname of the transferred file.

                    In case of the chrooted FTP session this field can be
                    interpreted as the pathname in the chrooted environment
                    (the default interpretation) or as the one in the real
                    file system. The second type of interpretation can be
                    enabled by the command-line options of the ftpd(8).

transfer-type  The single character that indicates the type of the trans-
                    fer. The set of possible values is:

                    a         An ascii transfer.

                    b         A binary transfer.

special-action-flag
                    One or more single character flags indicating any special
                    action taken. The set of possible values is:

                    _         No action was taken

                    C         The file was compressed (not in use).

                    U         The file was uncompressed (not in use).

                    T         The file was tar'ed (not in use).

direction            The direction of the transfer. The set of possible values
                    is:

                    o         The outgoing transfer.

                    i         The incoming transfer.

access-mode    The method by which the user is logged in. The set of pos-
                    sible values is:

                    a (anonymous)  The anonymous guest user.

                    g (guest)           The real but chrooted user (this capability
                                   is guided by ftpchroot(5) file).

                    r (real)           The real user.

username            The user's login name in case of the real user, or the
                    user's identification string in case of the anonymous user
                    (by convention it is an email address of the user).

service-name   The name of the service being invoked. The ftpd(8) utility
                    uses the ``ftp'' keyword.

                    The used method of the authentication. The set of possible
                    values is:

                    0         None.

                    1         RFC931 Authentication (not in use).

authenticated-user-id
                    The user id returned by the authentication method. The `*'
                    symbol is used if an authenticated user id is not avail-
                    able.

completion-status
                    The single character that indicates the status of the
                    transfer. The set of possible values is:

                    c         A complete transfer.

                    i         An incomplete transfer.
