The website you must know if you are going to be a Dynamiper.
Dynamips Official Blog, http://www.ipflow.utc.fr/blog/Dynagen Official website, http://dynagen.org/Winpcap Official website, http://www.winpcap.org/
Step by Step
1. Download Winpcap, http://www.winpcap.org/install/default.htm
2. Download Dynagen,http://sourceforge.net/project/showfiles.php?group_id=160317
3. Install Winpcap.
4. Install Dynagen.
Three shortcuts will appear on your desktop, Dynagen Sample labs (Folder), Dynamips Server, Network device list. Double-click Dynagen Sample labs and you will see a file called “all_config_options.txt”, which is quite useful for you. Open it by Wordpad instead of Notepad and view the options you can utilize in the labs.
Open “Simple lab 1” and right-click the simple1.net then choose “Edit network file”, and choose Wordpad to open it. It is a 7200 platform and there are two routers in the diagram using 160MB ram, respectively. The main configurations inside are as below.
5. Download Cisco IOS for Cisco 3600 serials.Although Dynamics support several Cisco platforms, personally I prefer 3640 when comparing the RAM requirement, modules support and IOS features. You can search IOS resources from internet yourself.
6. Put *.bin file (c3640-jk9s-mz.123-7.T12.bin in this guide) of your Cisco IOS in some folder. For example, D:\Dynamips.7. Copy simple1.net to the folder D:\Dynamips and change the file by Wordpad. You can also change its name to mylab.net, or the others as well. It doesn’t make any sense for the lab. Based on our information described above, we change the network file as below.8. Run “Dynamips Server” on your desktop. Maybe it will be blocked by Windows Firewall. Just Unblock it. Double-click your *.net file such as mylab.net. Use command “help” to illustrate all the commands you can used through Dynagen. The general commands are “start” and “telnet”.Now we run “start R1” and “telnet R1”. You might notice that there is an alert when you run the command to start R1. When you are running the router without “idle-pc value” configured, the CPU utilization of your computer will keep very high till 100% even only one router instance running.
9. Wait for router R1 has been started until the following message in your Telnet Session, “Would you like to enter the initial configuration dialog? [yes/no]:” . Come back to your Dynagen Window and type the command “idlepc get R1”. You must wait a while and some possible values will be supplied to you.
After you see the information, you can choose the number the system advised. For example, 6 and press Enter. By Windows Task Manager, You can check the CPU utilization when you apply the value to R1. If the CPU utilization is decreased from 100%, then copy the value that you applied, close the Dynagen window and Dynamips Server window.
10. Open your *.net file again and add the idlepc value to it, which is specific for current IOS image. For example,
So far to speak, all the installation and preparation has been finished. We can easily change network topology in the *.net file and simulate various networks following the options in file “all_config_options.txt”.

1. Download PEMU and decompress it to any folder.
2. Copy PIX OS to the same folder with PEMU.
3. Change the image in pemu.ini file, take pix802.bin for example.
4. Create one .bat file and edit it with the following contents. It’s in ONE line.
Pemu -net nic,vlan=1,macaddr=00:00:0c:00:00:01 -net udp,vlan=1,sport=8000,dport=9000,daddr=127.0.0.1 -net nic,vlan=2,macaddr=00:00:0c:00:00:02 -net udp,vlan=2,sport=8001,dport=9001,daddr=127.0.0.1 -net nic,vlan=3,macaddr=00:00:0c:00:00:03 -net udp,vlan=3,sport=8002,dport=9002,daddr=127.0.0.1 -serial telnet::4444,server -m 128 FLASH
5. Make a copy of FLASH.empty and change the name to FLASH.
6. Run the .bat file that created.
7. Telnet to 127.0.0.1 4444. If any problem occurred when decompressing the image, you have one option that you change the pix.bin to pix.rar and decompress then get the file pix. Copy it to the PEMU folder and change the pemu.ini to map to this image, “image=pix”.
8. The CPU utilization will be 100%, and there is no tool integrated in PEMU. Download BES and run it to control the CPU utilization.
9. Change your dynagen .net file as follows. If you’re not familiar with Dynamips, please see the post “Dynamips 10 Steps for Dummies” in this blog.
[[2610XM]]idlepc = 0×803f4b40image = F:\EMU\pemu\routers\c2600-is-mz.122-32.binram = 64
[[ROUTER R1]]f0/0 = NIO_udp:9000:127.0.0.1:8000[[ROUTER R2]]f0/0 = NIO_udp:9001:127.0.0.1:8001[[ROUTER R3]]f0/0 = NIO_udp:9002:127.0.0.1:8002
10. Now the PIX can communicate with the routers you configured and the result is,

Wireless Networking Printer

Wireless networking is all the rage. Learn how to set up a wireless computer network in your own house or small business.
Wireless networking is found across the world in coffee houses, restaurants, and libraries. In Europe and South America, it was chosen over standard wired networking due to the infrastructure and costs involved with retro-fitting older buildings for Ethernet networks. As standards were developed from 802.11b to the faster data transfer found in 802.11g, wireless networking became more viable as a choice for computer networks. Combined with the ease of setting up a wireless network it was only a matter of time before wireless networks became the prevalent choice in home networking.
Getting Started
In order to build a computer network, you have to have two or more computers. Any operating system can be networked together, however the steps involved with mixing operating systems requires skills beyond the scope of this article. For instructional purposes, we will only be using the Microsoft Windows family in this tutorial.
The additional components you need to build your wireless network are:
A wireless router.
One wireless network adapter for each computer or device that you wish to connect to the router.
Installing the network adapters
The first step is to install the wireless network adapters into each computer. For desktop computers using a PCI network adapter, you will need to power down the system, open up the case, and insert the adapter into a free PCI slot (the white slots running in a row down the back of the computer motherboard). Once you have seated the card firmly into the PCI slot, screw the card in to secure it, then close up the computer and restart it. Some cards are installed automatically, however you may need to provide the disk containing device drivers if prompted.
For a USB wireless adapter, simply plug it into a free USB port while the computer is running, and install drivers if prompted.
Laptop computers will either have a PCMCIA (the slot that is roughly 2 inches wide and ¼ of an inch high) card adapter or a USB adapter. Both can be plugged into the computer while it is running, though with the PCMCIA card adapter it is a good idea to power off before you plug it in. Install the drivers as required.
The router
Now choose a location for your router. If you have decided that you will use wired connections for any of your desktop systems, obviously you want it close to them. The router will need to be wired to your DSL or cable modem if you are planning to share internet through it.
Once you have found a location that is centralized, plug the router in. Verify that the 'WLAN' LED is lit up. To test connectivity, open a web-browser on one of your wireless computers and enter the default IP address of your router. This address can be found in your router's manual and generally starts with the numbers 192.168.xxx.xxx. If successful you should seen the router's configuration screen.
The first step you should take here is to change the administrator password of the router. Anyone who has the ability to access your router without your permission also knows that the default password for most routers is "admin" or blank.
DHCP and IP addressing
By default, your router will have a 'pool' of IP addresses that it will give to any computer that tries to connect to it wirelessly. This is known as a DHCP server (Dynamic Host Configuration Protocol). It makes it easier for a computer to connect to a network. Home users can take advantage of this option as you don't have to remember the range of IP addresses, the gateway interface, and the DNS server that your network uses; it is all done automatically for you.
If you decide to disable the DHCP feature, you will have to enter all of the addresses mentioned above manually.
Final thoughts
Setting up a wireless network at home is quite simple and most manufacturers offer excellent troubleshooting resources in the owner's manual so don't be afraid to read it.
The most common problem you will have is a weak signal. This can be monitored by the wireless adapter's icon in the toolbar. If it reports a weak signal, you can gain better throughput by moving your computer to another location, or relocating the router itself. The process of finding the strongest signal is done through trial and error.
Another problem you may run into is that older DSL modems/routers sometimes act as a DHCP server as well. You can not run two DHCP servers on a network because they cause conflicts. If this happens, I would suggest contacting your modem manufacturer and ask them how to turn off DHCP at the modem/router that is hardwired.
