Will calculate the Network Address, Broadcast Address, and number of hosts in a subnet given an IP address and Subnet Mask.

Subnet Mask may be entered in either dotted decimal notation or directly in number of bits masked.

You may also click on the Subnet Mask button to change to the Wildcard Mask view. Click again to go back to the Subnet Mask view.

Whats New in This Release:

· Fixes a bug in 1.4 where pressing enter in a field would cause both the Subnet Mask view and the Wildcard Mask view to appear and throw off the layout of the widget.

SubnetCalc is an IP subnet calculator.

IP Monitor is a handy application which automatically displays the current IP network (or subnet mask) address of your Macintosh right onto your desktop.

With IP Monitor, youll no longer have to open the TCP/IP (or MacTCP) control panel in order to view your Macintoshs IP (or subnet mask) address.IP Monitor is scriptable.

Whatmask GUI is a A.S.S. wrapper to the cli subnet mask calculator whatmask.

The package includes the whatmask source code and the A.S.S. source code.

httpScanner is a cocoa java utility to scan the subnet entered for http servers running on the most common ports and attempt to identify them.
It then reports back to you what servers are running on your subnet, what port, and what model of server is running.

httpScanner is multi-threaded for efficiency and speed.

httpScanner was developed and tested using OS X, Jaguar.

ZiskoCalc is a small Desktop-Toolkit that lets you convert values from many number-systems into others like hex, oct, bin, dec. Quick converting of full IP Addresses into different number Systems, CPU Benchmarking, get you System Up-Time and some other Statistics.

Some often used Tables for ASCII and ANSI Codes are included, too. The included Subnet Calculator Module does Subnet calculating for Class B and C Subnets and lets you generate Subnet- and Host-Lists, either as Tables on screen or export them as ASCII-Text file for further processing. ZiskoCalc is freeware and comes with no warranties. Is is availabe for Mac OS X, OS9 and Microsoft Windows Platforms.

IPGadget is a small calculator for verifying IPv4 address information. Given an IP address and network prefix size, IPGadget will show you:

* The subnet mask corresponding with the prefix size (eg "/24" = "255.255.255.0")
* The network address (ie, where the bits of the host portion are all zeroes)
* The broadcast address (ie, where the bits of the host portion are all ones)
* The range of valid host addresses for the subnet

IPGadget also highlights suspect addresses where:

* The IP address is either the network or broadcast address for the subnet, or is reserved (class E)
* The subnet portion of the network prefix is either all zeroes or all ones (classsic mode)
* The subnet mask is incorrect for the class of address

IPGadget is particularly useful when designing IPv4 networks. The prefix-size popup menu makes it easy to verify route aggregation or summarization masks, and the stepper quickly recalculates the address field for the next or previous subnet in sequence.

You choose whether to impose classful or classless rules. For example, sometimes its simpler to skip all-zeroes or all-ones subnets rather than waste time explaining Classless Inter-Domain Routing (CIDR) to people who should know better. Alternatively, if legacy devices in your network preclude you from using CIDR, IPGadgets online help includes an example explaining the classic rules.

IPGadget also provides a handy reference to address-class ranges, the ranges reserved for use in private internets, and the link-local range.

httpScanner is a cocoa java utility to scan the subnet entered for http servers running on the most common ports and attempt to identify them. This application, like all of my scanners, is multi-threaded for efficiency and speed. httpScanner was developed and tested using OS X, Jaguar.

IPCalc is a subnet calculator. It leverages the amazing SipCalc as its engine. The app is geared toward IT professionals and people who want to learn about IP subnetting. The basic input elements are: An IP address, expressed as xxx.xxx.xxx.xxx (e.g. 192.168.125.100) A subnet mask, expressed as dotted decimal xxx.xxx.xxx.xxx (e.g. 255.255.255.0) or a CIDR (number of bits) expressed as XX (e.g. 24) There are two modes of operation... basic and advanced. Advanced will show additional information (such as hex and binary forms). Additionally, the Advanced mode allows for "what if" analysis.

Whats New in This Release:

· Now a Universal Binary Application
· Minor optimizations.

Alphabet Salad is a simple game of searching for words on a grid to help you waste time. Now multiplayer (on a local subnet) so its even more like the famous-maker trademarked game not called Alphabet Salad.

Whats New in This Release:

· Fixed a bug which caused clicked letters to stay shaded and sometimes left a spinning progress indicator running when it shouldnt. Sorry, folks.

MacPing is a network troubleshooting tool. MacPing is a ping tool with a twist: it tests all the devices on a subnet concurrently, making it easy to see which devices are not performing up to par.

MacPing(tm) is an IP and AppleTalk network testing tool. Just as sonar or radar systems send a signal and wait for an echo, MacPing sends "probe packets" (ICMP or AppleTalk echo packets) into the network and waits for responses from the various devices on the network. The arrival of these response packets (or the lack of responses), along with the time the responses take to arrive, can tell a great deal about the network.

MacPing differs from other network testing programs in that it tests all the devices on a particular network in parallel. This allows you to compare the performance of different devices on the same wire to determine the cause of network problems.

MacPing can test devices on anywhere on your AppleTalk network - simply choose the desired zone from the Zone: popup menu. If that zone contains multiple networks, choose the desired network number from the Network: popup. MacPing can also test IP networks. You can enter a host name or IP address and MacPing will test that device. In addition, MacPing can automatically determine a hosts subnet, and test all the devices on that subnet.

nother computer? Or even better, run at the same time several Keynote shows on a huge plasma screens? How about projecting presentations from multiple computers and auto advance them in sync?

You can do all this with KeyShowX! Launch KeyShowX Client application alongside with your Keynote or PowerPoint installation. And then from any Mac or PC in the same subnet you can control presentation with KeyShowX Control application. No configuration efforts required: only enabling Mac OS X UI Scripting support. It is perfect companion to Keynote and PowerPoint for exhibition booths, multi-screen presentations and showroom environments.

Here are some key features of "KeyShowX":

· Control from single networked Mac or PC one or several Keynote and PowerPoint packages located at the same subnet. Sending controlling messages at the same time: imagine several Macs doing together Keynote s 3D transitions.
· You can remotely launch Keynote or PowerPoint with any ready presentation, start show, advance it, stop show, and quit.
· Remote auto advancing in sync any number of presentations with looping and fixed number of slides.


Limitations:

· Unregistered version of KeyShowX Client is limited to 20 commands per launch.

401(ok) is a quick and dirty hack to allow iTunes 4.0.1 to share musicbeyond your local network.

It redirects incoming connections on port 4689 to port 3689. Thisallows for the iTunes music sharing server normally run on port 3689(but with limited access), to be reached on port 4689 globally.

Thelocal network limitation in the iTunes sharing server is achieved bysending server responses with a low IP time-to-live. By doing a localport redirection, the server responses are sent with the normal TTL,and the "subnet" limitation is eliminated.

MyNet is a small application that scans your local subnet for the purpose of finding hosts on your segment. The ability to identify hosts on your network is critical when using wireless technology.

This tool is different from other scanning tools as it will find hosts regardless of any personal firewall which may be running on the host. This is achieved through the use of forced ARPs.

ONLY SCAN NETWORKS FOR WHICH YOU ARE AUTHORIZED TO SCAN!

Whats New in This Release:

· Now a Universal Binary
· Minor optimizations.

The name of this application says it all -- if it gave you a spark of hope, then read on, this app is for you.

Due to the way that most routers are configured, NetBooting is typically constrained within a subnet. This means that if you wanted to NetBoot all the machines in your organization (and I dont mean simultaneously) you would have two choices:

1. Have your network administrator configure your routers to add your NetBoot servers IP address to the list of IP Helper addresses or
2. Maintain a NetBoot server on every subnet of your network.

While the first option is the "Right Way®" to do NetBooting across subnets, it is poorly documented and often includes political battles that many people would rather not fight (which is too bad, its really quite easy and harmless to do). Option 2 is costly and probably not the most efficient use of resources, especially if you only NetBoot your machines once every few months for the purpose of reimaging them.

So what is left for those of us that simply want to occasionally NetBoot a bunch of machines scattered across a rather robust but fragmented network? In short, you can edit theOpen Firmware startup parameters such that your clients boot directly to your NetBoot server.

Whats New in This Release:

· Added support for EFI-based Macs
· Aplication is now a Universal binary
· Added support for "next boot only" option available to EFI-based Macs.

Davtri Fingerprinting HTTP Scanner is a Cocoa based http scanner which seaches servers hosts for http servers running on both common and uncommon ports. For every server it finds, it attempts to "fingerprint" (identify) which server software is running on that port.

Davtri Fingerprinting HTTP Scanner is an HTTP Scanner that searches on both common and uncommon ports and attempts to identify what http server is running.


This application allows you to scan one host at a time, a comma separated list of hosts or a whole subnet (subnets can be a little slow, but when scanning 254 hosts, you have to expect that).

The application also allows you to save the results in two different file formats. The first is a raw (plain text) format that can be used more easily by other software and scripts for automated analysis. The second format is a styled, valid xhtml report for a more formal and human readable report.

GlowWorm FW Lite is a rule-based network security and monitoring application that allows the user to define acceptable behavior on the basis of address, port and application.

GlowWorm FW Lite is a tool that will notify you with an authorization dialog about any unauthorized network activity.

Rules can be defined on the basis of a set of connection criteria include the addresses, ports, relevant endpoint and protocol. Additionally, rules can be restricted to a particular set of users, groups or applications, and the lifetime of a rule can be limited by the lifetime of that application or until the machine reboots.

Relative Network Names allow one to specify symbolic endpoint address like localhost, localnet or remotenet instead of having to "hard code" an ip subnet address.

Rule Actions can alert you using a user-customizable dialog message (based on an sprintf-like format so that you can choose what information to include), if a particular rule matches.

Support for incoming and listener connections provides a more precise means of controlling network traffic than offered by the Mac OS X Firewall.
Drag-and-drop rule re-ordering makes prioritizing rules an intuitive and easy process.
