Kết nối dynamips và pemu

[lemo]

Xin hởi mình đã kết nối dynamips và pemu đúng như hướng dẫn trên forum http://www.vnpro.org/forum/archive/i...p?t-12494.html, và cũng dùng mô hình như vậy, nhưng mìh không thể ping được giao diện inside của Pix từ R2, không biết là do cấu hình Pix sai hay cấu hình file net của dynamip.
Các bạn giúp mình với

Chào !!!
Hiện GNS3 đã giả lập được PIX, bạn xem hướng dẫn về GNS 3 tại đây :http://www.vnpro.org/forum/showthread.php?t=16328

Chúc bạn vui !!!

hi lemo,

PIX Emulation
PIX emulation was added with Dynagen 0.11.0, thanks to the PEMU emulator by Milen Svobodnikov, and Pemuwrapper by Thomas Pani. To add a firewall to your lab, first you must launch the Pemu Server. On Windows, use the “Pemu Server” shortcut on the desktop and in the Start menu. On Linux, use the “pemu-start.sh” script.

In your network file, define the connection to the pemu server and the firewall as shown here:

[localhost]

[[7200]]
image = \Program Files\Dynamips\images\C7200-jk9s-mz.124-12.bin
ram = 160
npe = npe-400

[[router R1]]
e1/0 = FW1 e0

[pemu localhost]

[[525]]
image = \Program Files\Dynamips\images\pix802.bin
serial = 0x12345678
key = 0x00000000,0x00000000,0x00000000,0x00000000

[[fw FW1]]

This .net file specifies the Pemuwrapper instance as running on “localhost”. It could be running also on another computer, creating a distributed lab. Then, specify the 525 section (signifying the PIX 525 that PEMU emulates) and set the defaults that will apply to all firewall instances on this PEMU server. Here you can set the “image”, ”key”, ”serial” and “ram” options. The [FW1] line creates the PIX 525 instance; whose Ethernet0 interface is connected to R1’s e1/0 interface (specified in router R1’s config).

This run the lab and you can list PEMU instances using the 'list' command:

=> list

Name Type State Server Console

R1 7200 stopped localhost:7200 2000

FW1 525 stopped localhost:10525 4000

PEMU firewalls can be stopped, started, reloaded, and of course you can attach to the console just like a virtual router. However, the following commands are not supported on PEMU firewalls:

import / export
suspend / resume
capture / filter (on firewall interfaces. You can instead capture on the “dynamips” side of the connection)
cpuinfo
copy / push

The following caveats apply to PEMU:

Currently, PEMU server only runs on Windows and Linux hosts (not OS X,). However Dynagen running on any platform can be used to communicate with a PEMU server running on a Linux or Windows host.
There is no concept of “idlepc” for PEMU; each PEMU device will consume 100% of a core. However the process does run at a low priority. You can choose to limit CPU consumption with a 3rd party tool like BES (on Windows) or cpulimit on Windows.
Dynagen does not currently support connecting PIX interfaces to NIOs (for example “e1 = NIO_gen_eth:eth0”). To get around this, bridge the connection with a virtual Ethernet switch like so:

[localhost]

[[ethsw sw1]]
1 = access 1
2 = access 1 NIO_gen_eth:eth0

[pemu localhost]

e1 = sw1 1

See the “pix” sample lab (in the sample_labs directory) for a more detailed example of utilizing emulated PIX firewalls in your labs.

Cảm ơn các bạn, mình sẽ thử cả hai cách này
thanks

Dynamips has changed the network world and it helped many network fans to obtain the network labs without paying any fee. The new simulator PEMU makes the security lab available on your computer.

PEMU 10 Steps for Dummies
by CiscoSpot
Any distribution is welcome, please feel free to contact net@netap.com
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 = 0×803f4b40
image = F:\EMU\pemu\routers\c2600-is-mz.122-32.bin
ram = 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,
