=head1 DESCRIPTION
=over 4
-=item new (HOST [,OPTIONS])
+=item new ([ HOST ] [, OPTIONS ])
This is the constructor for a new Net::FTP object. C<HOST> is the
name of the remote host to which an FTP connection is required.
+C<HOST> is optional. If C<HOST> is not given then it may instead be
+passed as the C<Host> option described below.
+
C<OPTIONS> are passed in a hash like fashion, using key and value pairs.
Possible options are:
+B<Host> - FTP host to connect to. It may be a single scalar, as defined for
+the C<PeerAddr> option in L<IO::Socket::INET>, or a reference to
+an array with hosts to try in turn. The L</host> method will return the value
+which was used to connect to the host.
+
+
B<Firewall> - The name of a machine which acts as an FTP firewall. This can be
overridden by an environment variable C<FTP_FIREWALL>. If specified, and the
given host cannot be directly connected to, then the
connection is made to the firewall machine and the string C<@hostname> is
-appended to the login identifier. This kind of setup is also refered to
+appended to the login identifier. This kind of setup is also referred to
as an ftp proxy.
B<FirewallType> - The type of firewall running on the machine indicated by
B<Debug> - debug level (see the debug method in L<Net::Cmd>)
-B<Passive> - If set to a non-zero value then all data transfers will be done
-using passive mode. This is not usually required except for some I<dumb>
-servers, and some firewall configurations. This can also be set by the
-environment variable C<FTP_PASSIVE>.
+B<Passive> - If set to a non-zero value then all data transfers will
+be done using passive mode. If set to zero then data transfers will be
+done using active mode. If the machine is connected to the Internet
+directly, both passive and active mode should work equally well.
+Behind most firewall and NAT configurations passive mode has a better
+chance of working. However, in some rare firewall configurations,
+active mode actually works when passive mode doesn't. Some really old
+FTP servers might not implement passive transfers. If not specified,
+then the transfer mode is set by the environment variable
+C<FTP_PASSIVE> or if that one is not set by the settings done by the
+F<libnetcfg> utility. If none of these apply then passive mode is
+used.
B<Hash> - If given a reference to a file handle (e.g., C<\*STDERR>),
print hash marks (#) on that filehandle every 1024 bytes. This
are displayed for all transfers. You can, of course, call C<hash()>
explicitly whenever you'd like.
+B<LocalAddr> - Local address to use for all socket connections, this
+argument will be passed to L<IO::Socket::INET>
+
If the constructor fails undef will be returned and an error message will
be in $@
no arguments are given then the C<Net::FTP> uses the C<Net::Netrc>
package to lookup the login information for the connected host.
If no information is found then a login of I<anonymous> is used.
-If no password is given and the login is I<anonymous> then the users
-Email address will be used for a password.
+If no password is given and the login is I<anonymous> then I<anonymous@>
+will be used for password.
If the connection is via a firewall then the C<authorize> method will
be called with no arguments.
Returns most significant digit of the response code.
-=item type (TYPE [, ARGS])
+=item ascii
-This method will send the TYPE command to the remote FTP server
-to change the type of data transfer. The return value is the previous
-value.
+Transfer file in ASCII. CRLF translation will be done if required
-=item ascii ([ARGS]) binary([ARGS]) ebcdic([ARGS]) byte([ARGS])
+=item binary
-Synonyms for C<type> with the first arguments set correctly
+Transfer file in binary mode. No transformation will be done.
-B<NOTE> ebcdic and byte are not fully supported.
+B<Hint>: If both server and client machines use the same line ending for
+text files, then it will be faster to transfer all files in binary mode.
=item rename ( OLDNAME, NEWNAME )
reason this method will not return an error, but setting it may cause
a subsequent data transfer to fail.
-=item rmdir ( DIR )
+=item rmdir ( DIR [, RECURSE ])
-Remove the directory with the name C<DIR>.
+Remove the directory with the name C<DIR>. If C<RECURSE> is I<true> then
+C<rmdir> will attempt to delete everything inside the directory.
=item mkdir ( DIR [, RECURSE ])
Returns the full pathname to the new directory.
+=item alloc ( SIZE [, RECORD_SIZE] )
+
+The alloc command allows you to give the ftp server a hint about the size
+of the file about to be transferred using the ALLO ftp command. Some storage
+systems use this to make intelligent decisions about how to store the file.
+The C<SIZE> argument represents the size of the file in bytes. The
+C<RECORD_SIZE> argument indicates a mazimum record or page size for files
+sent with a record or page structure.
+
+The size of the file will be determined, and sent to the server
+automatically for normal files so that this method need only be called if
+you are transferring data from a socket, named pipe, or other stream not
+associated with a normal file.
+
=item ls ( [ DIR ] )
Get a directory listing of C<DIR>, or the current directory.
the current directory with the same leafname as the remote file.
If C<WHERE> is given then the first C<WHERE> bytes of the file will
-not be transfered, and the remaining bytes will be appended to
+not be transferred, and the remaining bytes will be appended to
the local file if it already exists.
Returns C<LOCAL_FILE>, or the generated local file name if C<LOCAL_FILE>
is not given.
B<NOTE>: If for some reason the transfer does not complete and an error is
-returned then the contents that had been transfered will not be remove
+returned then the contents that had been transferred will not be remove
automatically.
=item put_unique ( LOCAL_FILE [, REMOTE_FILE ] )
Returns the size in bytes for the given file as stored on the remote server.
B<NOTE>: The size reported is the size of the stored file on the remote server.
-If the file is subsequently transfered from the server in ASCII mode
+If the file is subsequently transferred from the server in ASCII mode
and the remote server and local machine have different ideas about
"End Of Line" then the size of file on the local machine after transfer
may be different.
=item port ( [ PORT ] )
Send a C<PORT> command to the server. If C<PORT> is specified then it is sent
-to the server. If not, the a listen socket is created and the correct information
+to the server. If not, then a listen socket is created and the correct information
sent to the server.
