WU-FTPD 2.6.1
File Transfer Protocol (ftp) enables users to transfer files between a client system and a
remote server system. On the client system, a file transfer program provides the user
with an interface to transfer files; on the server, the requests are handled by the file
transfer daemon, ftpd. HP's implementation of the ftp daemon for HP-UX 11i and later
versions is based on the replacement ftp daemon developed at Washington University
known as WU-FTPD.
Summary of Change
The following changes have been made in WU-FTPD 2.6.1:
•The ftp daemon audits all the login activities irrespective of a success/failure login.
• WU-FTPD 2.6.1 logs bad login attempts to the /var/adm/btmps file.
NOTE Bad logins are not properly audited when a user fails to login as an “anonymous” or
“guest” user, as in the following cases:
• Incorrect permissions for the user's home directory in the FTP server
• Invalid entries in the /etc/passwd file for the anonymous or guest user
• Failure to set the effective user ID
• The following command-line options have been added:
— -w This is the default option which enables the wtmps and btmps
logins.
— -W This option disables both the wtmps and btmps logins.
