91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	18 * A <code>SFTPv3Client</code> represents a SFTP (protocol version 3)
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	19 * client connection tunnelled over a SSH-2 connection. This is a very simple
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	20 * (synchronous) implementation.
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	21 * <p/>
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	22 * Basically, most methods in this class map directly to one of
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	23 * the packet types described in draft-ietf-secsh-filexfer-02.txt.

91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	26 * <p/>
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	27 * Error handling: the methods of this class throw IOExceptions. However, unless
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	28 * there is catastrophic failure, exceptions of the type {@link SFTPv3Client} will
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	29 * be thrown (a subclass of IOException). Therefore, you can implement more verbose
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	30 * behavior by checking if a thrown exception if of this type. If yes, then you
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	31 * can cast the exception and access detailed information about the failure.

91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	34 * from the specs:

91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	36 * <li>SFTP v3 represents file names as strings. File names are

91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	38 * <li>File names starting with a slash are "absolute", and are relative to
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	39 * the root of the file system. Names starting with any other character
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	40 * are relative to the user's default directory (home directory).</li>
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	41 * <li>Servers SHOULD interpret a path name component ".." as referring to
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	42 * the parent directory, and "." as referring to the current directory.
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	43 * If the server implementation limits access to certain parts of the
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	44 * file system, it must be extra careful in parsing file names when
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	45 * enforcing such restrictions. There have been numerous reported
91a31873c42a start conversion from trilead to ganymed Carl Byington <carl@five-ten-sg.com> parents: diff changeset	46 * security bugs where a ".." in a path name has allowed access outside
