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

HP-Specific features
HP has introduced the following features in WU-FTPD 2.6.1:
• Command-Line Options
Following are the options included in WU-FTPD 2.6.1:
◦ -m number_of_tries
Specifies the number of tries for a bind() socket call.
◦ -n nice_value
Sets the nice value for an WU-FTPD process. When using this option, ensure that the nice
clause in the /etc/ftpd/ftpaccess file (see ftpaccess(4)) is not set.
◦ -B
Sets the buffer size of the data socket to blocks of 1024 bytes. The valid range for size
is from 1 to 64 (default is 56).
NOTE: A large buffer size improves the performance of WU-FTPD 2.6.1 on fast links
(for example, FDDI) but may cause long connection times on slow links (for example,
X.25).
◦ -p and -P
The -p option is used to allow private port access to the client. The -P option is used to
allow third party access and private port access.
These options are also available in WU-FTPD 2.4. These options do not exist in the
open-sourced version of WU-FTPD 2.6.1 but have been incorporated in HP’s port of
WU-FTPD for backward compatibility.
Other features
In addition to the features discussed in the previous sections, WU-FTPD 2.6.1 supports the following
features:
• Files greater than 2 GB
• Large user IDs (UIDs) and group IDs (GIDs)
