I was trying to install this simulator for winodws paltform , but i could not get success

I followed the instructions, but may be I missed something, which I did not figure out.
Download The current release is 0.2.4, published Feb 14, 2006 (you can consult the README file (http://www.ipflow.utc.fr/dynamips/README-0.2.4.txt)).

You have to download only one binary file corresponding to your architecture:

Executable for Windows (with Cygwin DLL) (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.4-cygwin.zip)

If you are using the Windows version, you have to download and install the WinPcap library (http://www.winpcap.org/). It is now possible to access the Ethernet card of host machine to send/receive packets on the LAN.

    I've only run the Linux version with the Dynagen front-end... I think there is the windows installer for that which simplifies the configuration of Dynamips.

    Obvious questions -- do you have a 7200 IOS image? What was the error? Did the Windows install fail (bad download, corrupt file)? Or did everything install "correctly" that you can tell.... and then what?

    Thanks mikej412
    Obvious questions -- do you have a 7200 IOS image?
    I did not realize that I should have got IOS image, then I have been told , that i should get the IOS image first.

    I already tried to use it but each I tried I only get a router with a single ethernet interface...

    Can someone explain me how to use it ?

    I found some examples but same results... icon_evil.gif

    Hello !

    I've the following IOS image c7200-js-mz.124-3.bin

    When I run the command dynamips c7200-js-mz.124-3.bin it doesn't work as you can see below :

    I've also tried the following commands (without any success) :

    Hello all,

    Thanks for pointing this out, there are errors in the README file (it was not updated appropriately for the examples).

    Nawakette> For the IOS loading error, I suggest that you use the 0.2.5-pre20, it has a fix for the Windows platform concerning this problem.

    Niamor> You're right, the examples are incorrect, sorry for that. I updated the README file provided on the home page with the correct syntax.

    Example: dynamips -p 0:C7200-IO-FE:udp:10001:127.0.0.1:10002 c7200-js-mz.124-3.bin

    In fact, with 0.2.4, the syntax is :

    dynamips -p 0:C7200-IO-FE -s 0:0:udp:10001:127.0.0.1:10002 [...]

    The -p option is used to put a Port Adapter in the specified slot, and the -s option is used to bind a network descriptor to the specified slot + sub-interface (before the 0.2.4, only PA with 1 port were supported).

    Another example that shows how to bind a network descriptor to the interface Serial2/4:

    dynamips -p 2:PA-8T -s 2:4:udp:10001:127.0.0.1:10002 [...]

    On Windows platform, the IOS image name must be the last parameter on the command line.

    Don't hesitate to ask questions on the blog if you have problems :)

    Chris.

    Thank you for your message Chris.

    Could you please tell me where I can download this version 0.2.5-pre20 ?
  • NawaketteNawakette Member Posts: 33 ■■□□□□□□□□
    I'm sorry tu disturb you but I'm not sure that I'm using the right procedure... icon_redface.gif

    Is it necessary to run dynamips c7200-js-mz.124-3.bin and, afterwards, dynamips -p 0:C7200-IO-FE -s 0:0:udp:10001:127.0.0.1:10002 c7200-js-mz.124-3.bin as you explained below ?

    Many thanks for the link Mike.

    Unfortunately, with the version 0.2.5-pre20, problems still occur...

    Must stop playing now.... but for anyone with the hardware and 7200 IOS image this is pretty darn sweet! icon_thumright.gif

    When I get the chance I'm going to toss some of my extra network adapters in the Linux machine running this and have the emulated 7200s talk to my real routers. icon_cool.gif

    You get the load failure where I get
    Loading ELF file 'c7200-js-mz.124-3.bin'...

    Did you unzip your image to speed up the load? I didn't get around to doing that since I just wanted to give the windows versions a quick test only. If you ftp'd the image, did you do it in binary mode (windows usually defaults to ascii transfer mode).

    My c7200-js-mz.124-3.bin IOS image is 24,108,420 bytes and shows up in Windows Explorer as 23,544KB

    Hi everybody !

    No Mike, I didn't unzip the bin file... But I think it was not necessary (extension is .bin, not .zip).

    My c7200-js-mz.124-3.bin IOS image shows up in Windows Explorer as 23,544KB too...

    icon_cry.gif I don't understand why it doesn't work icon_cry.gif

    I just tried it again.... with a different image... and got your problem. icon_cry.gif

    But :D

    The image I had used successfully yesterday was also in the directory with dynamips... When I just added the path info to the IOS name, I was working again!
    dynamips images\c7200-jk9o3s-mz.123-8.T.bin
    

    Hopefully its just that simple for you! I think I copied that one test image into the dynamips directory even before I tried running straight from the command line since I knew dynagen had been taking care of the little configuration details...

    It's working now !!! :D

    It was not the same problem as yours, but what you said helped me to think about something : use the right image name ( icon_confused.gif I made a tiny mistake in the name icon_rolleyes.gificon_wink.gif ).

    Now, I'm waiting for the end of the decompression...

    Thanks Mike

    :D

    And I was happy just running the Linux version.... I guess I should load the windows version on my main laptop -- even running 1 instance to check out an IOS feature makes it worth the disk space. And it might give me an excuse to get a new laptop -- maybe a dual core with 2 gigs of memory. :D

    I did run the 2 instances on an old P4 with 768Meg of memory, and probably could have gone for a 3rd instance.

    Hello,

    1- I have been able to load 2 instances on my PC but these routers can neither ping each other nor outside ip addresses.

    My command line is :

    dynamips "images/C7200-P-Mz 122-12.bin" -p 0:C7200-IO-FE -s 0:0:udp:10001:127.0.0.1:10002

    and for second instance is :

    dynamips "images/C7200-P-Mz 122-12.bin" -p 0:C7200-IO-FE -s 0:0:udp:10002:127.0.0.1:10001

    2- Are these virtual routers able to communicate with outside network (i.e our LAN) ? I have some real routers out there and I am trying to communicate with them.

    3- Can someone please tell me how can I have these two (or more) virtual routers communicate with each other ? (I need this to speed up my CCNP certification at home :) )

    Regards,
    Mac

    2 - yes, there is a way to configure that....

    3 - I've had no problem with the virtual router ethernet ports communicating with each other on either the Linux or Windows version. I've just had to give the virtual router some time to recognize and process the no shutdown command before it recognized the virtual ethernet ports.


    I haven't added the additional network cards on the Linux system yet -- but I do remember seeing the documention on one of the web sites mentioned above about having multiple virtual routers on a machine communicating with real routers. I haven't tried (or had the time) to figure out how to talk between different virtual routers running on different machines -- but Dynagen makes that look like its simple.

    From your command line it looks like you're running on Linux. If I get a chance I'll try your command lines on my Linux box. On windows it wanted the image name at the end -- but then I did get a load error even when I put my valid image name at the end. Then my windows desktop machine lost its boot drive. icon_sad.gif

    What dynamips version are you running? And you're running a -P- IOS -- that's a Service Provider version, right? Have you tried an -i- or -j- IOS?

    Check out the blog link in a post above -- someone there would probably be able to get back to you faster (and with a better answer :D ) before I do here.

    I have a real lab and should be using it (and fixing my desktop, and my main server that lost its boot drive last week).... but dynamip (and dynagen) are fun to play with.
