Datagram socket to interract through the firewall.<BR>
Can be used same way as the normal DatagramSocket. One should
be carefull though with the datagram sizes used, as additional data
is present in both incomming and outgoing datagrams.
<p>
SOCKS5 protocol allows to send host address as either:
<ul>
<li> IPV4, normal 4 byte address. (10 bytes header size)
<li> IPV6, version 6 ip address (not supported by Java as for now).
22 bytes header size.
<li> Host name,(7+length of the host name bytes header size).
</ul>
As with other Socks equivalents, direct addresses are handled
transparently, that is data will be send directly when required
by the proxy settings.
<p>
<b>NOTE:</b><br>
Unlike other SOCKS Sockets, it <b>does not</b> support proxy chaining,
and will throw an exception if proxy has a chain proxy attached. The
reason for that is not my laziness, but rather the restrictions of
the SOCKSv5 protocol. Basicaly SOCKSv5 proxy server, needs to know from
which host:port datagrams will be send for association, and returns address
to which datagrams should be send by the client, but it does not
inform client from which host:port it is going to send datagrams, in fact
there is even no guarantee they will be send at all and from the same address
each time.

You can specify timeout for which we should be checking EOF condition
on the primary connection. Timeout is in milliseconds. Specifying 0 as
timeout implies infinity, in which case method will block, until
connection to proxy is closed or an error happens, and then return false.
<p>
One possible scenario is to call isProxyactive(0) in separate thread,
and once it returned notify other threads about this event.
@param timeout For how long this method should block, before returning.
@return true if connection to proxy is active, false if eof or error
condition have been encountered on the connection.

/**
* A <code>SFTPv3Client</code> represents a SFTP (protocol version 3)
* client connection tunnelled over a SSH-2 connection. This is a very simple
* (synchronous) implementation.
* <p>
* Basically, most methods in this class map directly to one of
* the packet types described in draft-ietf-secsh-filexfer-02.txt.
* <p>
* Note: this is experimental code.
* <p>
* Error handling: the methods of this class throw IOExceptions. However, unless
* there is catastrophic failure, exceptions of the type {@link SFTPv3Client} will
* be thrown (a subclass of IOException). Therefore, you can implement more verbose
* behavior by checking if a thrown exception if of this type. If yes, then you
* can cast the exception and access detailed information about the failure.
* <p>
* Notes about file names, directory names and paths, copy-pasted
* from the specs:
* <ul>
* <li>SFTP v3 represents file names as strings. File names are
* assumed to use the slash ('/') character as a directory separator.</li>
* <li>File names starting with a slash are "absolute", and are relative to
* the root of the file system. Names starting with any other character
* are relative to the user's default directory (home directory).</li>
* <li>Servers SHOULD interpret a path name component ".." as referring to
* the parent directory, and "." as referring to the current directory.
* If the server implementation limits access to certain parts of the
* file system, it must be extra careful in parsing file names when
* enforcing such restrictions. There have been numerous reported
* security bugs where a ".." in a path name has allowed access outside
* the intended area.</li>
* <li>An empty path name is valid, and it refers to the user's default
* directory (usually the user's home directory).</li>
* </ul>
* <p>
* If you are still not tired then please go on and read the comment for
* {@link #setCharset(String)}.
