The HP implementation of the FTP daemon for HP-UX 11i core networking
is based on the WU-FTPD daemon, version 2.4. Additional security
correction has been added to WU-FTPD 2.6.1. HP recommends upgrading
to WU-FTPD 2.6.1 for enhanced security.
For systems on HP-UX 11.0, you can upgrade to WU-FTPD 2.6.1
from either the legacy FTP version that is delivered with the core
networking products on 11.0, or from WU-FTPD 2.4, which has been
made available as the patch PHNE_21936.
WU-FTPD 2.6.1 is downloadable from the HP Software Depot for systems
running HP-UX 11.0 or HP-UX 11i version 1. The URL is http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl?productNumber=3DWUFTPD26.
WU-FTPD 2.6.1 is a core product on HP-UX 11i version 2.
