1256 | =head1 DESCRIPTION | |
1257 | ||
1258 | C<Net::FTP> is a class implementing a simple FTP client in Perl as | |
1259 | described in RFC959. It provides wrappers for a subset of the RFC959 | |
1260 | commands. | |
1261 | ||
1262 | =head1 OVERVIEW | |
1263 | ||
1264 | FTP stands for File Transfer Protocol. It is a way of transferring | |
1265 | files between networked machines. The protocol defines a client | |
1266 | (whose commands are provided by this module) and a server (not | |
1267 | implemented in this module). Communication is always initiated by the | |
1268 | client, and the server responds with a message and a status code (and | |
1269 | sometimes with data). | |
1270 | ||
1271 | The FTP protocol allows files to be sent to or fetched from the | |
1272 | server. Each transfer involves a B<local file> (on the client) and a | |
1273 | B<remote file> (on the server). In this module, the same file name | |
1274 | will be used for both local and remote if only one is specified. This | |
1275 | means that transferring remote file C</path/to/file> will try to put | |
1276 | that file in C</path/to/file> locally, unless you specify a local file | |
1277 | name. | |
1278 | ||
1279 | The protocol also defines several standard B<translations> which the | |
1280 | file can undergo during transfer. These are ASCII, EBCDIC, binary, | |
1281 | and byte. ASCII is the default type, and indicates that the sender of | |
1282 | files will translate the ends of lines to a standard representation | |
1283 | which the receiver will then translate back into their local | |
1284 | representation. EBCDIC indicates the file being transferred is in | |
1285 | EBCDIC format. Binary (also known as image) format sends the data as | |
1286 | a contiguous bit stream. Byte format transfers the data as bytes, the | |
1287 | values of which remain the same regardless of differences in byte size | |
1288 | between the two machines (in theory - in practice you should only use | |
1289 | this if you really know what you're doing). | |
1290 | ||
1291 | =head1 CONSTRUCTOR | |
1292 | ||
1293 | =over 4 | |
1294 | ||
f92f3fcb | 1295 | =item new ([ HOST ] [, OPTIONS ]) |
406c51ee JH |
1296 | |
1297 | This is the constructor for a new Net::FTP object. C<HOST> is the | |
d1be9408 | 1298 | name of the remote host to which an FTP connection is required. |
406c51ee | 1299 | |
f92f3fcb GB |
1300 | C<HOST> is optional. If C<HOST> is not given then it may instead be |
1301 | passed as the C<Host> option described below. | |
1302 | ||
406c51ee JH |
1303 | C<OPTIONS> are passed in a hash like fashion, using key and value pairs. |
1304 | Possible options are: | |
1305 | ||
f92f3fcb GB |
1306 | B<Host> - FTP host to connect to. It may be a single scalar, as defined for |
1307 | the C<PeerAddr> option in L<IO::Socket::INET>, or a reference to | |
1308 | an array with hosts to try in turn. The L</host> method will return the value | |
1309 | which was used to connect to the host. | |
1310 | ||
1311 | ||
d1be9408 | 1312 | B<Firewall> - The name of a machine which acts as an FTP firewall. This can be |
406c51ee JH |
1313 | overridden by an environment variable C<FTP_FIREWALL>. If specified, and the |
1314 | given host cannot be directly connected to, then the | |
1315 | connection is made to the firewall machine and the string C<@hostname> is | |
1316 | appended to the login identifier. This kind of setup is also refered to | |
d1be9408 | 1317 | as an ftp proxy. |
406c51ee | 1318 | |
302c2e6b GB |
1319 | B<FirewallType> - The type of firewall running on the machine indicated by |
1320 | B<Firewall>. This can be overridden by an environment variable | |
1321 | C<FTP_FIREWALL_TYPE>. For a list of permissible types, see the description of | |
1322 | ftp_firewall_type in L<Net::Config>. | |
1323 | ||
406c51ee JH |
1324 | B<BlockSize> - This is the block size that Net::FTP will use when doing |
1325 | transfers. (defaults to 10240) | |
1326 | ||
1327 | B<Port> - The port number to connect to on the remote machine for the | |
1328 | FTP connection | |
1329 | ||
1330 | B<Timeout> - Set a timeout value (defaults to 120) | |
1331 | ||
1332 | B<Debug> - debug level (see the debug method in L<Net::Cmd>) | |
1333 | ||
1334 | B<Passive> - If set to a non-zero value then all data transfers will be done | |
1335 | using passive mode. This is not usually required except for some I<dumb> | |
1336 | servers, and some firewall configurations. This can also be set by the | |
1337 | environment variable C<FTP_PASSIVE>. | |
1338 | ||
a816fa74 MG |
1339 | B<Hash> - If given a reference to a file handle (e.g., C<\*STDERR>), |
1340 | print hash marks (#) on that filehandle every 1024 bytes. This | |
1341 | simply invokes the C<hash()> method for you, so that hash marks | |
1342 | are displayed for all transfers. You can, of course, call C<hash()> | |
1343 | explicitly whenever you'd like. | |
406c51ee | 1344 | |
edd55068 GB |
1345 | B<LocalAddr> - Local address to use for all socket connections, this |
1346 | argument will be passed to L<IO::Socket::INET> | |
1347 | ||
406c51ee JH |
1348 | If the constructor fails undef will be returned and an error message will |
1349 | be in $@ | |
1350 | ||
1351 | =back | |
1352 | ||
1353 | =head1 METHODS | |
1354 | ||
1355 | Unless otherwise stated all methods return either a I<true> or I<false> | |
1356 | value, with I<true> meaning that the operation was a success. When a method | |
1357 | states that it returns a value, failure will be returned as I<undef> or an | |
1358 | empty list. | |
1359 | ||
1360 | =over 4 | |
1361 | ||
1362 | =item login ([LOGIN [,PASSWORD [, ACCOUNT] ] ]) | |
1363 | ||
1364 | Log into the remote FTP server with the given login information. If | |
1365 | no arguments are given then the C<Net::FTP> uses the C<Net::Netrc> | |
1366 | package to lookup the login information for the connected host. | |
1367 | If no information is found then a login of I<anonymous> is used. | |
12df23ee GB |
1368 | If no password is given and the login is I<anonymous> then I<anonymous@> |
1369 | will be used for password. | |
406c51ee JH |
1370 | |
1371 | If the connection is via a firewall then the C<authorize> method will | |
1372 | be called with no arguments. | |
1373 | ||
1374 | =item authorize ( [AUTH [, RESP]]) | |
1375 | ||
1376 | This is a protocol used by some firewall ftp proxies. It is used | |
1377 | to authorise the user to send data out. If both arguments are not specified | |
1378 | then C<authorize> uses C<Net::Netrc> to do a lookup. | |
1379 | ||
1380 | =item site (ARGS) | |
1381 | ||
1382 | Send a SITE command to the remote server and wait for a response. | |
1383 | ||
1384 | Returns most significant digit of the response code. | |
1385 | ||
73c20b23 | 1386 | =item ascii |
406c51ee | 1387 | |
73c20b23 | 1388 | Transfer file in ASCII. CRLF translation will be done if required |
406c51ee | 1389 | |
73c20b23 | 1390 | =item binary |
406c51ee | 1391 | |
73c20b23 | 1392 | Transfer file in binary mode. No transformation will be done. |
406c51ee | 1393 | |
73c20b23 GB |
1394 | B<Hint>: If both server and client machines use the same line ending for |
1395 | text files, then it will be faster to transfer all files in binary mode. | |
406c51ee JH |
1396 | |
1397 | =item rename ( OLDNAME, NEWNAME ) | |
1398 | ||
1399 | Rename a file on the remote FTP server from C<OLDNAME> to C<NEWNAME>. This | |
1400 | is done by sending the RNFR and RNTO commands. | |
1401 | ||
1402 | =item delete ( FILENAME ) | |
1403 | ||
1404 | Send a request to the server to delete C<FILENAME>. | |
1405 | ||
1406 | =item cwd ( [ DIR ] ) | |
1407 | ||
1408 | Attempt to change directory to the directory given in C<$dir>. If | |
1409 | C<$dir> is C<"..">, the FTP C<CDUP> command is used to attempt to | |
1410 | move up one directory. If no directory is given then an attempt is made | |
1411 | to change the directory to the root directory. | |
1412 | ||
1413 | =item cdup () | |
1414 | ||
1415 | Change directory to the parent of the current directory. | |
1416 | ||
1417 | =item pwd () | |
1418 | ||
1419 | Returns the full pathname of the current directory. | |
1420 | ||
686337f3 JH |
1421 | =item restart ( WHERE ) |
1422 | ||
1423 | Set the byte offset at which to begin the next data transfer. Net::FTP simply | |
1424 | records this value and uses it when during the next data transfer. For this | |
1425 | reason this method will not return an error, but setting it may cause | |
1426 | a subsequent data transfer to fail. | |
1427 | ||
73c20b23 | 1428 | =item rmdir ( DIR [, RECURSE ]) |
406c51ee | 1429 | |
73c20b23 GB |
1430 | Remove the directory with the name C<DIR>. If C<RECURSE> is I<true> then |
1431 | C<rmdir> will attempt to delete everything inside the directory. | |
406c51ee JH |
1432 | |
1433 | =item mkdir ( DIR [, RECURSE ]) | |
1434 | ||
1435 | Create a new directory with the name C<DIR>. If C<RECURSE> is I<true> then | |
1436 | C<mkdir> will attempt to create all the directories in the given path. | |
1437 | ||
1438 | Returns the full pathname to the new directory. | |
1439 | ||
dea4d7df GB |
1440 | =item alloc ( SIZE [, RECORD_SIZE] ) |

1442 | The alloc command allows you to give the ftp server a hint about the size | |
1443 | of the file about to be transfered using the ALLO ftp command. Some storage | |
1444 | systems use this to make intelligent decisions about how to store the file. | |
1445 | The C<SIZE> argument represents the size of the file in bytes. The | |
1446 | C<RECORD_SIZE> argument indicates a mazimum record or page size for files | |
1447 | sent with a record or page structure. | |
1448 | ||
1449 | The size of the file will be determined, and sent to the server | |
1450 | automatically for normal files so that this method need only be called if | |
1451 | you are transfering data from a socket, named pipe, or other stream not | |
1452 | associated with a normal file. | |

1454 | =item ls ( [ DIR ] ) |
1455 | ||
406c51ee JH |
1456 | Get a directory listing of C<DIR>, or the current directory. |
1457 | ||
1458 | In an array context, returns a list of lines returned from the server. In | |
1459 | a scalar context, returns a reference to a list. | |
1460 | ||
1461 | =item dir ( [ DIR ] ) | |
1462 | ||
1463 | Get a directory listing of C<DIR>, or the current directory in long format. | |
1464 | ||
1465 | In an array context, returns a list of lines returned from the server. In | |
1466 | a scalar context, returns a reference to a list. | |
1467 | ||
1468 | =item get ( REMOTE_FILE [, LOCAL_FILE [, WHERE]] ) | |
1469 | ||
1470 | Get C<REMOTE_FILE> from the server and store locally. C<LOCAL_FILE> may be | |
d1be9408 | 1471 | a filename or a filehandle. If not specified, the file will be stored in |
406c51ee JH |
1472 | the current directory with the same leafname as the remote file. |
1473 | ||
1474 | If C<WHERE> is given then the first C<WHERE> bytes of the file will | |
1475 | not be transfered, and the remaining bytes will be appended to | |
1476 | the local file if it already exists. | |
1477 | ||
1478 | Returns C<LOCAL_FILE>, or the generated local file name if C<LOCAL_FILE> | |
686337f3 | 1479 | is not given. If an error was encountered undef is returned. |
406c51ee JH |
1480 | |
1481 | =item put ( LOCAL_FILE [, REMOTE_FILE ] ) | |
1482 | ||
1483 | Put a file on the remote server. C<LOCAL_FILE> may be a name or a filehandle. | |
1484 | If C<LOCAL_FILE> is a filehandle then C<REMOTE_FILE> must be specified. If | |
1485 | C<REMOTE_FILE> is not specified then the file will be stored in the current | |
1486 | directory with the same leafname as C<LOCAL_FILE>. | |
1487 | ||
1488 | Returns C<REMOTE_FILE>, or the generated remote filename if C<REMOTE_FILE> | |
1489 | is not given. | |
1490 | ||
1491 | B<NOTE>: If for some reason the transfer does not complete and an error is | |
1492 | returned then the contents that had been transfered will not be remove | |
1493 | automatically. | |
1494 | ||
1495 | =item put_unique ( LOCAL_FILE [, REMOTE_FILE ] ) | |
1496 | ||
1497 | Same as put but uses the C<STOU> command. | |
1498 | ||
1499 | Returns the name of the file on the server. | |
1500 | ||
1501 | =item append ( LOCAL_FILE [, REMOTE_FILE ] ) | |
1502 | ||
1503 | Same as put but appends to the file on the remote server. | |
1504 | ||
1505 | Returns C<REMOTE_FILE>, or the generated remote filename if C<REMOTE_FILE> | |
1506 | is not given. | |
1507 | ||
1508 | =item unique_name () | |
1509 | ||
1510 | Returns the name of the last file stored on the server using the | |
1511 | C<STOU> command. | |
1512 | ||
1513 | =item mdtm ( FILE ) | |
1514 | ||
1515 | Returns the I<modification time> of the given file | |
1516 | ||
1517 | =item size ( FILE ) | |
1518 | ||
1519 | Returns the size in bytes for the given file as stored on the remote server. | |
1520 | ||
1521 | B<NOTE>: The size reported is the size of the stored file on the remote server. | |
1522 | If the file is subsequently transfered from the server in ASCII mode | |
1523 | and the remote server and local machine have different ideas about | |
1524 | "End Of Line" then the size of file on the local machine after transfer | |
1525 | may be different. | |
1526 | ||
1527 | =item supported ( CMD ) | |
1528 | ||
1529 | Returns TRUE if the remote server supports the given command. | |
1530 | ||
1531 | =item hash ( [FILEHANDLE_GLOB_REF],[ BYTES_PER_HASH_MARK] ) | |
1532 | ||
1533 | Called without parameters, or with the first argument false, hash marks | |
1534 | are suppressed. If the first argument is true but not a reference to a | |
1535 | file handle glob, then \*STDERR is used. The second argument is the number | |
1536 | of bytes per hash mark printed, and defaults to 1024. In all cases the | |
1537 | return value is a reference to an array of two: the filehandle glob reference | |
1538 | and the bytes per hash mark. | |
1539 | ||
1540 | =back | |
1541 | ||
1542 | The following methods can return different results depending on | |
1543 | how they are called. If the user explicitly calls either | |
1544 | of the C<pasv> or C<port> methods then these methods will | |
1545 | return a I<true> or I<false> value. If the user does not | |
1546 | call either of these methods then the result will be a | |
1547 | reference to a C<Net::FTP::dataconn> based object. | |
1548 | ||
1549 | =over 4 | |
1550 | ||
1551 | =item nlst ( [ DIR ] ) | |
1552 | ||
d1be9408 | 1553 | Send an C<NLST> command to the server, with an optional parameter. |
406c51ee JH |
1554 | |
1555 | =item list ( [ DIR ] ) | |
1556 | ||
1557 | Same as C<nlst> but using the C<LIST> command | |
1558 | ||
1559 | =item retr ( FILE ) | |
1560 | ||
1561 | Begin the retrieval of a file called C<FILE> from the remote server. | |
1562 | ||
1563 | =item stor ( FILE ) | |
1564 | ||
1565 | Tell the server that you wish to store a file. C<FILE> is the | |
1566 | name of the new file that should be created. | |
1567 | ||
1568 | =item stou ( FILE ) | |
1569 | ||
1570 | Same as C<stor> but using the C<STOU> command. The name of the unique | |
1571 | file which was created on the server will be available via the C<unique_name> | |
1572 | method after the data connection has been closed. | |
1573 | ||
1574 | =item appe ( FILE ) | |
1575 | ||
1576 | Tell the server that we want to append some data to the end of a file | |
1577 | called C<FILE>. If this file does not exist then create it. | |
1578 | ||
1579 | =back | |
1580 | ||
1581 | If for some reason you want to have complete control over the data connection, | |
1582 | this includes generating it and calling the C<response> method when required, | |
1583 | then the user can use these methods to do so. | |
1584 | ||
1585 | However calling these methods only affects the use of the methods above that | |
1586 | can return a data connection. They have no effect on methods C<get>, C<put>, | |
1587 | C<put_unique> and those that do not require data connections. | |
1588 | ||
1589 | =over 4 | |
1590 | ||
1591 | =item port ( [ PORT ] ) | |
1592 | ||
1593 | Send a C<PORT> command to the server. If C<PORT> is specified then it is sent | |
c8570720 | 1594 | to the server. If not, then a listen socket is created and the correct information |
406c51ee JH |
1595 | sent to the server. |
1596 | ||
1597 | =item pasv () | |
1598 | ||
1599 | Tell the server to go into passive mode. Returns the text that represents the | |
1600 | port on which the server is listening, this text is in a suitable form to | |
1601 | sent to another ftp server using the C<port> method. | |
1602 | ||
1603 | =back | |
1604 | ||
1605 | The following methods can be used to transfer files between two remote | |
1606 | servers, providing that these two servers can connect directly to each other. | |
1607 | ||
1608 | =over 4 | |
1609 | ||
1610 | =item pasv_xfer ( SRC_FILE, DEST_SERVER [, DEST_FILE ] ) | |
1611 | ||
1612 | This method will do a file transfer between two remote ftp servers. If | |
1613 | C<DEST_FILE> is omitted then the leaf name of C<SRC_FILE> will be used. | |
1614 | ||
1615 | =item pasv_xfer_unique ( SRC_FILE, DEST_SERVER [, DEST_FILE ] ) | |
1616 | ||
1617 | Like C<pasv_xfer> but the file is stored on the remote server using | |
1618 | the STOU command. | |
1619 | ||
1620 | =item pasv_wait ( NON_PASV_SERVER ) | |
1621 | ||
1622 | This method can be used to wait for a transfer to complete between a passive | |
1623 | server and a non-passive server. The method should be called on the passive | |
1624 | server with the C<Net::FTP> object for the non-passive server passed as an | |
1625 | argument. | |
1626 | ||
1627 | =item abort () | |
1628 | ||
1629 | Abort the current data transfer. | |
1630 | ||
1631 | =item quit () | |
1632 | ||
1633 | Send the QUIT command to the remote FTP server and close the socket connection. | |
1634 | ||
1635 | =back | |
1636 | ||
1637 | =head2 Methods for the adventurous | |
1638 | ||
1639 | C<Net::FTP> inherits from C<Net::Cmd> so methods defined in C<Net::Cmd> may | |
1640 | be used to send commands to the remote FTP server. | |
1641 | ||
1642 | =over 4 | |
1643 | ||
1644 | =item quot (CMD [,ARGS]) | |
1645 | ||
1646 | Send a command, that Net::FTP does not directly support, to the remote | |
1647 | server and wait for a response. | |
1648 | ||
1649 | Returns most significant digit of the response code. | |
1650 | ||
1651 | B<WARNING> This call should only be used on commands that do not require | |
1652 | data connections. Misuse of this method can hang the connection. | |
1653 | ||
1654 | =back | |
1655 | ||
1656 | =head1 THE dataconn CLASS | |
1657 | ||
1658 | Some of the methods defined in C<Net::FTP> return an object which will | |
1659 | be derived from this class.The dataconn class itself is derived from | |
1660 | the C<IO::Socket::INET> class, so any normal IO operations can be performed. | |
1661 | However the following methods are defined in the dataconn class and IO should | |
1662 | be performed using these. | |
1663 | ||
1664 | =over 4 | |
1665 | ||
1666 | =item read ( BUFFER, SIZE [, TIMEOUT ] ) | |
1667 | ||
1668 | Read C<SIZE> bytes of data from the server and place it into C<BUFFER>, also | |
1669 | performing any <CRLF> translation necessary. C<TIMEOUT> is optional, if not | |
d1be9408 | 1670 | given, the timeout value from the command connection will be used. |
406c51ee JH |
1671 | |
1672 | Returns the number of bytes read before any <CRLF> translation. | |
1673 | ||
1674 | =item write ( BUFFER, SIZE [, TIMEOUT ] ) | |
1675 | ||
1676 | Write C<SIZE> bytes of data from C<BUFFER> to the server, also | |
1677 | performing any <CRLF> translation necessary. C<TIMEOUT> is optional, if not | |
d1be9408 | 1678 | given, the timeout value from the command connection will be used. |
406c51ee JH |
1679 | |
1680 | Returns the number of bytes written before any <CRLF> translation. | |
1681 | ||
686337f3 JH |
1682 | =item bytes_read () |
1683 | ||
1684 | Returns the number of bytes read so far. | |
1685 | ||
406c51ee JH |
1686 | =item abort () |
1687 | ||
1688 | Abort the current data transfer. | |
1689 | ||
1690 | =item close () | |
1691 | ||
1692 | Close the data connection and get a response from the FTP server. Returns | |
1693 | I<true> if the connection was closed successfully and the first digit of | |
1694 | the response from the server was a '2'. | |

1709 | =item B<HELP> | |
1710 | ||
1711 | Ask the server for "helpful information" (that's what the RFC says) on | |
1712 | the commands it accepts. | |
1713 | ||
1714 | =item B<MODE> | |

1737 | =head1 REPORTING BUGS | |
1738 | ||
1739 | When reporting bugs/problems please include as much information as possible. | |
1740 | It may be difficult for me to reproduce the problem as almost every setup | |
1741 | is different. | |
1742 | ||
1743 | A small script which yields the problem will probably be of help. It would | |
1744 | also be useful if this script was run with the extra options C<Debug => 1> | |
1745 | passed to the constructor, and the output sent with the bug report. If you | |
1746 | cannot include a small script then please include a Debug trace from a | |
1747 | run of your program which does yield the problem. | |
