GNS3-0.3.2-win32-all-in-one

2008-01-20T21:07:00.000+07:00

GNS3 is a graphical network simulator that allows you to design complex network topologies and to launch simulations on them.

To allow complete simulations, GNS3 is strongly linked with :

* Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems.
* Dynagen, a text-based front-end for Dynamips.

GNS3 is a excellent complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications.

It can also be used to experiment features of Cisco IOS or to check configurations that need to be deployed later on real routers.

This project is an open source product that may be used on multiple platforms, including Windows, Linux, and MacOS X.

WinAgents RouterTweak 2.0.1.1526

2007-12-29T18:12:00.000+07:00

WinAgents RouterTweak is a specialized terminal shell making it easier to control the configuration of routers, switches and firewalls from the Cisco Systems company.

Knowing the principles of working with the command line interface of Cisco devices, you can use WinAgents RouterTweak to automate the most common tasks of network device administration. This approach saves your time by allowing you to hand over routine operations to the program. Here are some benefits you get by using WinAgents RouterTweak:

Having specified the username and password for connecting to a device only once, you will not have to spend time on entering them again when you connect to your router next time. WinAgents RouterTweak will enter the account data itself and switch to the privileged mode if necessary.

Just click once to get the configuration of your device in a visual form. Syntax highlighting and the structure tree of the device configuration will allow you to quicker find your bearings among numerous configuration commands.

WinAgents RouterTweak allows you to do without a TFTP server while editing access control lists. You can add, edit and remove commands located in the middle of ACLs. The program knows about the peculiarities of using the command line interface with Cisco access control lists and takes them into account while editing ACLs.

It is easier to edit configuration commands due to the context help system. While you are adding a new command to the configuration file, WinAgents RouterTweak requests its possible parameters from the device. In the process of editing commands, you see the list of available variants for each command all the time and can select one of them without entering the entire string.

MultiNetwork Manager v9.0.0.1

2007-12-29T09:59:00.000+07:00

The 21st century Internet generation is mobile, flexible and demand network access when moving around. The benefits are obvious, but the technical complexity for the end-user is increasing.

We need more than just a movable laptop. We need our laptop to connect to the Internet, corporate LANs and home networks. And to do this securely we need to deal not only with connectivity barriers but also with enabling, disabling and configuring VPNs, personal firewalls, proxies, e-mail clients etc.

MultiNetwork Manager 9 makes the above simple and secure!

How much of your link is being utilized?

2007-12-10T20:24:00.000+07:00

Having a large link size doesn't guarantee that the link's bandwidth can be fully utilized. Your operating system's window size and latency are both factors on whether the link can be filled to its capacity.

To calculate the maximum bandwidth per flow, divide the operating system's window size by the latency. You can then take this value and divide it by the link size to get the percent of the link that can be utilized for a single flow. There will be several examples to help you understand these calculations.

Step 1: Determining the window size

Use the chart below to find typical window sizes for popular operating systems.

Operating System	Window Size (KB)
Windows 95	8
Windows 98	8
Windows NT 4.0	8
Windows 2000	16
HP-UX 11	32
MAC OS 9	32
LINUX 2.4	64
Windows XP	64

Step 2: Calculating the latency

To estimate the latency on your link, ping the router on the other side of your link. Use the statistic for average round trip time. This statistic is measured in milliseconds; you'll need to convert it to seconds (divide by 1000).

Step 3: Doing the math

The formula for calculating the percent utilization of the link is:

((window_size * 8) / latency_seconds) / link_size

Note: 8 is the number of bits per byte.

Let's look at several examples.

Example 1: High latency

In the first example, the network is experiencing high latency on a smallish link.

Operating System: Windows 2000 (16KB window size)

Latency: 600 ms (0.6 seconds)

Link Size: T1 (1.5 Mbps)

Maximum bandwidth per flow: (16* 8) / 0.6 = 213 Kbps

Divide this number by the link size to get the percent link utilization of a single flow:

213 Kbps / 1.5 Mbps = .14 = 14% utilization

Therefore, with only one flow, 86 percent of the link goes unused.

Example 2: Large link

In the second example, the network has a large link and moderate latency.

Operating System: Windows XP (64KB window size)

Latency: 30 ms (.03 seconds)

Link Size: 45 Mbps

Maximum bandwidth per flow: (64* 8) / .03 = 17,067 Kbps

Divide this by the link size to get the percent link utilization of a single flow:

17,067 Kbps / 45 Mbps = .38 = 38% utilization

In this example, with only one flow, 62 percent of the link goes unused.

Example 3: Compression

In this example, the link has increased its virtual bandwidth using Packeteer's Compression Module. Therefore, the virtual link size should be used in the calculation instead of the physical link size. To calculate the virtual link size, you need to estimate the compression savings you expect to have on the link (for instance, 60%). The formula to calculate the virtual link size is:

link_size / (1-compression_savings)

For example, the virtual link size of a 2 Mbps link that is expected to get 60% compression savings is 2/(1-0.6) = 5 Mbps.

Let's continue this example to find out the percent utilization of a link that's using compression.

Operating System: Windows 2000 (16KB window size)

Latency: 150 ms (0.15 seconds)

Virtual Link Size: 5 Mbps

Maximum bandwidth per flow: (16* 8) / 0.15 = 853 Kbps

Divide this number by the link size to get the percent link utilization of a single flow:

853 Kbps / 5 Mbps = .17 = 17% utilization

A single flow can fill 17% of the virtual link, leaving 83% unutilized.

Traffic Control And Report addon for IPCop project

2007-12-10T15:01:00.000+07:00

This addon is a billing system for workgroups. It's dedicated to tariffication of traffic downloaded by GREEN or BLUE interface users. It's also dedicated to control access to ipcop box. All source code of this addon is distributed under the terms of the GPL.

This addon uses ipac-ng packet to make calculations. Ipcop includes ipac-ng by default. TCAR uses sendEmail v1.52 by Brandon Zehm. SendEmail is distributed under the terms of the GPL too.

Addon controls user access to ipcop box by ip and mac addresses through GREEN and BLUE interfaces. If user's ip and mac are not in user list then this user will be blocked - he will not be able to receive packets from ipcop box. This addon counts traffic which goes from ipcop box to ip addresses of GREEN and BLUE interface network.

At the end of the day it sends short report to user's e-mail. Also this addon sends general report to administrator's e-mail and to financial manager's e-mail.

Addon allows setting up maximal allowed traffic for every user per day, week or month. If user exceed his limit his traffic will be blocked and user will be notified by e-mail. When period is over traffic becomes unblocked again."
