current-time The current local time in the form "DDD MMM dd hh:mm:ss

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-timeThe 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).

fer. The set of possible values is:

a An ascii transfer.

b A binary transfer.

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:

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:

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

transfer. The set of possible values is:

c A complete transfer.
