NcFTPs purpose is to provide a powerful and flexible interface to the Internet standard File Transfer Protocol. It is intended to replace the stock ftp program that comes with the system.

Although the program appears to be rather spartan, youll find that ncftp has a wealth of valuable performance and usage features. The program was designed with an emphasis on usability, and it does as much as it can for you automatically so you can do what you expect to do with a file transfer program, which is transfer files between two interconnected systems.

Some of the cooler features include progress meters, filename completion, command-line editing, background processing, auto-resume downloads, bookmarking, cached directory listings, host redialing, working with firewalls and proxies, downloading entire directory trees, etc., etc.

The ncftp distribution comes with the useful utility programs ncftpget(1) and ncftpput(1) which were designed to do command-line FTP. In particular, they are very handy for shell scripts. This version of ncftp no longer does command-line FTP, since the main ncftp program is more of a browser-type program.

Net::Hotline::Client is a Perl library for the Hotline internet client.

SYNOPSIS

use Net::Hotline::Client;

$hlc = new Net::Hotline::Client;
$hlc->connect("127.0.0.1")

$hlc->chat_handler(&Chat_Handler);
$hlc->msg_handler(&Msg_Handler);

Net::Hotline::Client is a class implementing a Hotline internet client in Perl. It was specifically developed to aid in the creation of Hotline "bots," although its suitable for most other tasks as well. Hotline is an internet client/server system thats sort of a cross between IRC and a BBS. See http://www.hotlinesw.com/ for more information.

This document assumes you have some knowledge of the Hotline client. If not, I suggest downloading it from the URL above. (Its shareware. Mac and PC versions are available)

HTTunnel::Client is a client class for Apache::HTTunnel.

SYNOPSIS

my $hc = new HTTunnel::Client("http://localhost/httunnel") ;
$hc->connect(tcp, $some_host, $some_port) ;

$hc->print(some request) ;
my $some_response = $hc->read(1024) ;

$ch->close() ;

HTTunnel::Client is the client class to Apache::HTTunnel. It allows the creation of a network connection tunnelled through HTTP. All data sent and received during this connection will be transported inside normal HTTP requests.

HTTunnel::Client extends LWP::UserAgent, so all LWP::UserAgent methods are available through HTTunnel::Client.

CONSTRUCTORS

new ( URL, [ARGS] )

Creates an HTTunnel::Client object that will use URL to contact the Apache::HTTunnel server. ARGS are is passed directly to the LWP::UserAgent constructor.

METHODS

connect ( PROTO, HOST, PORT, [TIMEOUT] )

Asks the Apache::HTTunnel server to establish a connection of protocol PROTO to HOST:PORT. An exception is thrown if an error occurs.

Accepted values for PROTO are tcp and udp.

print ( DATA )

Asks the Apache::HTTunnel server to write DATA to the established remote connection. An exception is thrown if an error occurs.
DATA can be a scalar or a list, in which case the list items are concatenated together.

read ( LEN, [TIMEOUT], [LIFELINE], [LIFELINE_CUT_ACTION] )

Asks the Apache::HTTunnel server to read up to LEN bytes from the established remote connection. An exception is thrown if an error occurs.

When trying to read, HTTunnel::Client will establish an HTTP connection to the Apache::HTTunnel server asking that LEN bytes be read. If no data is available after TIMEOUT seconds (the default value is 15 seconds), the HTTP connection is closed by the server and the read method will establish a new one. This will go on until some data or EOF is returned.

Therefore read will return only when some (or no more) data is available to be read (like the regular read).

LIFELINE can be any valid filehandle from which one can read. If used, read will interrupt its connection loop and execute LIFELINE_CUT_ACTION when data (or EOF) is available to be read from LIFELINE. It will then return undef.
LIFELINE_CUT_ACTION wust be a CODE ref. The default value is

sub {die("lifeline cutn")}

These features can be used if you want fork and to start a process that does nothing but reads and returns the data via a pipe. You can then use a second pipe to make sure the reader process terminates when the master process terminates.

Here is an example:

my $lifeline = new IO::Pipe() ;
my $reader = new IO::Pipe() ;
my $pid = fork() ;
if ($pid){
$reader->reader() ;
$lifeline->writer() ;

# Read data from $reader...
}
else {
$reader->writer() ;
$reader->autoflush(1) ;
$lifeline->reader() ;

while (1){
my $data = $hc->read(1024, 15, $lifeline, sub {exit()}) ;
exit() unless defined($data) ;
print $reader $data ;
}
}
close ( )

Asks the Apache::HTTunnel server to close a previously established connection.
get_peer_info ( )

The get_peer_info method returns information about the remote connection. A string containing the IP address and port number, separated by a colon (:) is returned. This method can be useful with UDP connections to validate the sender of each packet.

request_callback ( REQUEST )

The request_callback method is a callback method that can be used to access the HTTP::Request object just before it is sent. The default implementation does nothing.

response_callback ( RESPONSE )

The response_callback method is a callback method that can be used to access the HTTP::Response object just after it is received. The default implementation does nothing.

SQuirreL SQL Client is a graphical Java program that will allow you to view the structure of a JDBC compliant database, browse the data in tables, issue SQL commands etc. The minimum version of Java supported is 1.4.x. We recommend 1.5.x. See the Old Versions page for versions of SQuirreL that will work with older versions of Java.

SQuirreLs functionality can be extended through the use of plugins. A short introduction can be found here. To see the change history (including changes not yet released) click here.

Susan Cline graciously took the time to document the steps she followed to setup an Apache Derby database from scratch and use the SQuirreL SQL Client to explore it.
Quite some time ago Kulvir Singh Bhogal wrote a great tutorial on SQuirreL and published it at the IBM developerWorks site. He has kindly allowed us to mirror it locally. The tutorial is not really up to date but especially for doing the first steps it is still of help.

SQuirrel was originally released under the GNU General Public License. Since version 1.1beta2 it has been released under the GNU Lesser General Public License.

Whats New in This Release:

1716859 Cant see data in content tab or row count tab (MS SQLServer databases
with a dash ("-") in their name would cause the content tab or row count
tabs to render no data.

1714476: (DB copy uses wrong case for table names) The copy operation would
sometimes fail to select records from the source table. Since the
case for the source table is always known to be correct, the plugin
no longer erroneously attempts to correct the case.

1700093: Formatter fails for insert script with multiple subselects

Refactoring Plugin: SQL-Server needs eol between GO and statement.

Fixed bug which appeared while editing tables in PostgreSQL 8.1. If the table
was created without an OID column, the last column would not be editable.

Fix for issue where dates arent correctly displayed or updated when using
treat date as timestamp pref in the SQl Editor result panel.

Use the last directory that a file was imported from when importing additional
files for binary fields.

1699294: Squirrel imports BLOB, but does not update data

Oracle Plugin: Handle slashes when they are used as statement separators.

137984 (Bug in alias delete) The problem was that notifications were being
sent to the alias drop-down that the item was being deleted which trigger an
update and new selection forcing the connect to alias window to be launched.
Now, the alias drop down is disabled while the update is happening and enabled
immediately afterward.

POE::Component::Client::SMTP is a Perl module for asynchronous mail sending with POE. Thus your program isnt blocking while busy talking with an (E)SMTP server.

SYNOPSIS

Warning! The following examples are not complete programs, and arent designed to be run as full blown applications. Their purpose is to quickly introduce you to the module.

For complete examples, check the eg directory that can be found in the distributions kit.

A simple example:

# load PoCoClient::SMTP
use POE::Component::Client::SMTP;
# spawn a session
POE::Component::Client::SMTP->send(
From => foo@baz.com,
To => john@doe.net,
Server => relay.mailer.net,
SMTP_Success => callback_event_for_success,
SMTP_Failure => callback_event_for_failure,
);
# and you are all set ;-)
A more complex example:
# load PoCoClient::SMTP
use POE::Component::Client::SMTP;
# spawn a session
POE::Component::Client::SMTP->send(
# Email related parameters
From => foo@baz.com,
To => [
john@doe.net,
andy@zzz.org,
peter@z.net,
george@g.com,
],
Body => $email_body, # heres where your message is stored
Server => relay.mailer.net,
Timeout => 100, # 100 seconds before timeouting
# POE related parameters
Alias => pococlsmtpX,
SMTP_Success => callback_event_for_success,
SMTP_Failure => callback_event_for_failure,
);
# and you are all set

Gimp::ScriptFu::Client is a Perl client for the GNU Image Manipulation Program.

Gimp::ScriptFu::Client acts as a source filter in a Scheme script that uses Text::Template to preprocess any embedded Perl fragments contained between { } brackets before sending the resulting Scheme to a Gimp Script-Fu server. Each Perl fragment may or may not produce a Scheme fragment.
The Scheme script becomes a standalone client application.

This permits using Perl for getting parameters from the real world or for generating complex Scheme expressions, that would be more difficult or impossible with plain Scheme.

It also makes it possible to do Perlish things with Gimp if you cant do the compiler stuff for Gimp/Gimp::Fu for your OS. All recent Gimp versions include the Script-Fu server.
