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)
• Trusted system features
Changed and Removed Features
There are no changed or removed features in WU-FTPD 2.6.1.
