WU-FTPD 2.6.1 release notes (5900-1739, May 2011)

Enabling the Identification Protocol (RFC 1413)
The Identification Protocol, /usr/bin/ident, enables you to determine the identity of a user of
a particular TCP connection. For a particular TCP port number pair, identd returns a character
string that identifies the owner of that connection on the system of the server. You can use the -I
daemon option to enable RFC 1413-based authentication. By default, this authentication is disabled.
New feature related to data transfer
The following lists the data transfer features:
• For statistical purposes, you can track the total bytes of data transferred. Also, you can limit
the number of data bytes that a user, in any given class, can transfer. You can specify a
directive in the /etc/ftpd/ftpaccess file to limit the number of bytes incoming, outgoing,
or both.
The syntax for the directive is as follows:
data-limit [raw] in out total count [class]
A default limit is specified to all the classes for which you have not specified a limit. When
the FTP session logs off, this directive prints the number of files and the number of bytes
transferred.
• You can limit the number of data files that a user, in the given class, can transfer in a session.
You can specify a directive in the /etc/ftpd/ftpaccess file to limit the number of incoming
files, outgoing files, or both.
The syntax for the directive is as follows:
file-limit [raw] in out total count [class]
If you do not specify a class, a default limit is specified to all the classes for which a limit is
not specified.
For more information, type man 4 ftpaccess at the HP-UX prompt.
Field added to the /var/adm/syslog/xferlog file
A new field is added to the /var/adm/syslog/xferlog file to indicate the completion status
of the data transfer. A field value of C indicates complete transfer.
For more information on the new fields in the /var/adm/syslog/xferlog file, see xferlog(5).
