Free internet address bar entry software for linux

Internet Storm Center is a clone of the simple little Windows Konfabulator ISCTracker widget by Bob Rudis. It puts a little coloured globe on your desktop, with the colour of the land corresponding to the current level of Internet Storm Tracker.

Clicking on the globe takes you directly to isc.sans.org.

RFC822 Address Parser Library provides application developers with a complete parser for RFC822 addresses. Not only can you use the library to verify that RFC822 addresses are syntactically correct, you can also have an address split up into its semantic parts, what is needed when deciding where to route an address to, etc.
What is quite unique is that librfc822 does indeed parse all address types allowed by the standard. That includes such weird things as "address groups" or addresses with whitespace and comments throw in. Take a look at this beast to get an idea:
testing my parser : peter.simons@gmd.de,
(peter.)simons@rhein.de ,,,,,
testing my parser ,
it rules < @peti.gmd.de,@listserv.gmd.de:simons @ cys .de >
;
,
peter.simons@acm.org
That is indeed a legal e-mail address in RFC822 messages. It contains five separate addresses, which are grouped together. Heres the parsed result:
peter.simons@gmd.de
simons@rhein.de
simons@ieee.org
< @peti.gmd.de,@listserv.gmd.de:simons@cys.de >
peter.simons@acm.org
simons@rhein.de
simons@rhein.de
simons@rhein.de
In case you wonder: The strange looking address thats listed fourth is a so called "routing address" -- and yes, thats a legal e-mail address, too. These were popular in the early days of the Internet. Back then, every mail server that relayed an e-mail put its own address into this construct so that bounces could be routed the same way back that they originally went.
The address says that the mail should be send to the host peti.gmd.de, then to listserv.gmd.de, and from there it should be delivered (using any route) to the address simons@cys.de. These days, such addresses can hardly be used, because nobody relays for other recipients anymore. Still, these are legal.
librfc822 provides you with several routines that parse the different flavours of e-mail addresses as defined in the standard. The results will be placed in a rfc822address structure and returned. If constructs are parsed that may contain multiple addresses, you can pass a "committer" class to the function, which is called every time a correct address is found and may append it to a container of your choice.
Enhancements:
- The library has been re-released under an all-permissive license.

Address Book Continued provides a multi-user AJAX address book Web application.

It also makes use of AJAX, which means that page reloads only happen on login/logout; the rest of the operations is handled asynchronously in the background. Its well usable, even over slow connections.

You can even install ABC on your desktop PC and configure it so that it doesnt require login for connections coming from the local computer.

Gip is an IP address calculator that integrates well with the GNOME desktop environment.

Gip provides system administrators with tools for IP address based calculations. For example, an administrator who needs to find out which IP prefix length equals the IP netmask 255.255.240.0, just types in the mask and gets the prefix length presented. But many more advanced calculations can be made.

Gip can convert an address range into a list of prefix lengths. It can also split subnets using a given IP netmask or IP prefix length. Many more calculations are possible.

Convert::yEnc::Entry is a Perl module as an entry in a Convert::yEnc::RC database.

SYNOPSIS

use Convert::yEnc::Entry;

$entry = new Convert::yEnc::Entry { size => 10000 };
$entry = new Convert::yEnc::Entry { size => 50000, part => 1 };

$entry = load Convert::yEnc::Entry "10000t10000";
$entry = load Convert::yEnc::Entry "20000t1-20000t1-2";

$ok = $entry->ybegin( { size=>10000 } );
$ok = $entry->ypart ( { begin=>1, end=>10000 } );
$ok = $entry->yend ( { size=>10000 } );

$entry->complete and ...

print "$entryn";

ABSTRACT

An entry in a Convert::yEnc::RC database

Convert::yEnc::Entry manages a single entry in a Convert::yEnc::RC database

Mail::RFC822::Address is a Perl extension for validating email addresses according to RFC822.

SYNOPSIS

use Mail::RFC822::Address qw(valid validlist);

if (valid("pdw@ex-parrot.com")) {
print "Thats a valid addressn";
}

if (validlist("pdw@ex-parrot.com, other@elsewhere.com")) {
print "Thats a valid list of addressesn";
}

Mail::RFC822::Address validates email addresses against the grammar described in RFC 822 using regular expressions. How to validate a user supplied email address is a FAQ (see perlfaq9): the only sure way to see if a supplied email address is genuine is to send an email to it and see if the user recieves it. The one useful check that can be performed on an address is to check that the email address is syntactically valid. That is what this module does.

This module is functionally equivalent to RFC::RFC822::Address, but uses regular expressions rather than the Parse::RecDescent parser. This means that startup time is greatly reduced making it suitable for use in transient scripts such as CGI scripts.

valid ( address )

Returns true or false to indicate if address is an RFC822 valid address.

validlist ( addresslist )

In scalar context, returns true if the parameter is an RFC822 valid list of addresses.

In list context, returns an empty list on failure (an invalid address was found); otherwise a list whose first element is the number of addresses found and whose remaining elements are the addresses. This is needed to disambiguate failure (invalid) from success with no addresses found, because an empty string is a valid list
