WU-FTPD 2.6.1 release notes (July 2010)

NOTE: You cannot selectively allow PORT and PASV data connections in an IPv6
environment.
• The keepalive Clause
The keepalive clause allows you to control network disconnect by setting the
TCP SO_ALIVE option for data sockets. You can specify yes to set the TCP option,
or no to use the system default settings, which is usually off. HP recommends that
you set the keepalive clause to yes to retain the network traffic connected.
The syntax for keepalive clause is as follows:
keepalive yes no
• The /etc/ftpd/ftpaccess log Clause
The log clause is changed to allow logging transfers to both the /var/adm/
syslog/syslog and /var/adm/syslog/xferlog files. This option enables
you to redirect the logging messages for incoming and outgoing transfers to the
/var/adm/syslog/syslog file. If you do not specify this option, the messages
are written to the /var/adm/syslog/xferlog file.
The general syntax to redirect messages is as follows:
log sysloglog syslog+xferlog
• File Retrieval
You can specify certain clauses to control whether a real or guest user is allowed
access to areas on the FTP site other than their home directories.
The syntax for the clauses that control access to areas on the FTP site is as follows:
restricted-uid <uid-range>[...]
restricted-gid <gid-range>[...]
unrestricted-uid <uid-range>[...]
unrestricted-gid <gid-range>[...]
NOTE: For all these clauses, you must copy the libraries
/usr/lib/libnss_files.1 and /usr/lib/libdld.2 to the /usr/lib
directory of the current environment.
• Virtual Server
You can use the virtual server clauses to restrict user access to both the virtual and
non-virtual domains. Additionally, you can use the options specified in the
virtual clause to display the virtual host name.
The syntax for the virtual clause is as follows:
virtual <address> allow <username> [ username ...]
virtual <address> deny <username> [ username ...]
virtual <address> private
virtual <address> hostname email string
