GNS 3 not capable of running more than 10 devices

Anyone having problems booting more than 9 devices it fails on the 10 giving the error..

 

Error:Could not communicate with dynamips server localhost

It may have crashed. Check the dynamis server output

Exiting...

global name 'socket' is not defined

 

Its the IEBW v5 .gns file not modified. It some one has a solution...

  • I think the issue here is with how much memory and horsepower (CPU speed) that you have.  I bought a computer a couple of months ago and have successfully gotten (16) 3725 routers to boot.  

    Here are the details about the new computer:  Intel® Core™2 Quad processor Q8200; 6GB DDR2 memory, Windows Vista 64-bit

    What are the details on the computer you are running this on?

     

     

  • Intel Core 2 Quad

    Q 6600 @ 2.4 GHz

    WinXp Sp 2 (3 GB Ram)

     

    Problem has been solved the gns topology has once instance and the dynamips .net file has 2 instances.. But is really bogs down my system. I think i switch over to Ubuntu and try it over.

  • I did!

    the only way I resolved it, is by running the "ine.routing.and.switching.topology.5.00.net"(works fine and load all the routers/switches) and modified the files (.net)

    If you need to open and tweak the .net file I would recommend using "NOTEPAD++"

    MY PC: Intel Xeon (CPU= X5355 @ 2.66GHz(8 CPUx)

                Memory 8192MB RAM


     


     

     

  • That CPU should be able to handle it.  Try adding another 2 or 3 Gig of RAM.  Shouldn't cost you over $100 for that, and heck....you probably could use it anyway.

    I have found that the Vol 4.1 labs are the most effective for the GNS3/Dynamips.  If you create the text files for the initial router config and save the topo for each lab under a topic, the only thing that is left is to be able to focus on what that mini-topic is really trying to show you and only configure that specific piece.  It takes a while the first time to create the .net files and the text files setting up the router, but the next  time you go through them...you can blow through the whole series of labs..like OSPF - in less than 2 hours.

    Although I do have the horsepower to run the full topo for Vol5, I have given up on it for now.  The issues with the NM-16ESW, spanning-tree, and the port-channels....It is much more worth my time and mental energy to not spend 30 minutes troubleshooting why something isn't working....when the root of the problem is the shortcomings of the switching environment and trying to force the emulation software to match the scenario in the workbook.  

    If you successfully get everything working and are able to work out all the kinks using GNS3, please let me know how you did it and what to look out for.

  • Actually i have 8 GB of memory but 32 bit os can only handle about 3GB and the rest is paged. I used a sotware bes 1.3.8 to give more power to GNS3 as apposed to reducing it, well it drained the cpu but i booted all the devices.

     

    However  the disappointment arrived while i was configuring the (3725)switches, i could create the vlan but couldnt apply it ( the moment you use the apply keyword it would set it to client mode on reseting it back to server, would still work ! ).

     

    Im done and fed up with this for now, it would be nice to know which standard images work well.

     

    I think im going to go with your advice and do 4.1 . And work my way up with some real rack time in the future.

  • Got it working at last the second part of the 7201 has been replaced with 3640 . I would prefer to change all of it to a  3640 image for all so that the load is less.

    Fow now however running both is duable. May be in the future it would advisavle to load balance between 2 pc so that load is less, im still to work out how thats done and im sure that would work out so that load is divided.

    I use Windows 7 (64bits) and load the VMware for anything 32bit....

    I am using it to follow along with the INE CCIE Routing & Switching Advanced Technologies Class (great stuff)

    but for switching I would stick to the real equipment and take my time on a rack rental.

  • Im still posting till some takes notice and finds a solution. I tried the new IEBW which was posted and still no changes. I tried and port-cahnnel between sw1 and sw2 and the rest you can see it a 3725 image. Im not sure how the guys at IEBW are getting it to work

  • Well, not sure what you question is in your last post, however it appears you were trying to configure L3 etherchannel and that is not supported by the NM-16ESW, not a Dynamips problem:

    http://www.cisco.com/en/US/products/hw/modules/ps2797/products_qanda_item09186a00802c9e7a.shtml#qa20

    A. The EtherSwitch modules do not support these features:

    • Layer 3 (L3) switching (which the router performs)

    • Dynamic VLAN for an access port

    • VLAN Trunk Protocol (VTP) pruning

    • Per-port enabling/disabling of unknown multicast and unicast packets

    • CGMP client rate-limit

    • Cisco Cluster Management Suite (CMS) support

    • Cisco Emergency Responder support

    • IEEE 802.3af-compliant Power over Ethernet (PoE)


  • Any work around solution to this ?

  • Dont use GNS3, it sucks. Stick to Dynamips/Dynagen by itself.

  • I started with GNS3 tool as looked a lot easier, after having similar issues.

     

    I installed ubuntu as dual boot on my T61p laptop and works a dream running dynamips/dynagen simple enough to use, you just need to change IEWB config slightly.

     

    Will be looking at purchasing workbooks once company approves now :-)

  • Hi there,

     

    In the end i decided to take a rack on rent, it less of a headache too. Contact me on [email protected] should you need any help.

     

    I sleep eay these days.[H]

  • i run full IE v5 vol 1 on GNS3.. only shortcomings are switching for which i use rack rental. 

    My laptop is core 2 duo with 4 gb of ram and every thing works great, i am using ubuntu for this purpose and run 3725 latest code :) i have almost 14 devices and adding 3-4 more devices will not do any harm to my PC.[8-)]

  • Hi Nadeem,

     

    Similar setup to one I have done on mine, expect you have 2GB extra RAM which I'm considering to move up to.

     

    I've heard rumours that once BGP enables it slows things down? Is this true?

  • Thank you to EVERYONE who posted in this thread.   Dynamips/GNS3 is both a blessing and a curse.   If you have tweaked it much, you know what I mean.

    I run it on a Macbook Pro, and it works well.   I would like to share with you one significant CPU related issue I found.   If I boot a computer, and it is waiting on a "return" press, the CPU sticks to the roof.    So when you boot all your rotuers, make sure to offer a "return" to each console, and set the exec-timeout to 0 to disable it, otherwise you may be back in high cpu land when it times out.

    Again, thanks to all for your assistance to each other.   May you all have success in your learning and CCIE goals.

    Keith

  • With GNS3 I'm having problems booting more than 9 devices it fails on the 10th giving the error..

    Error:Could not communicate with dynamips server localhost

    It may have crashed. Check the dynamis server output

    Exiting...

    global name 'socket' is not defined

    Its the Dynamips Vol II v5 .gns file not modified. If someone has a solution...

    I have a 3Ghz Quad CPU and 8 GB of mem on Win 7 - 64 bit. I've been using Dynamips and decided

    to try GNS3. Any help on resolving this issue would be greatly appreciated.

  • Not really played around much with GNS 3 but seems like there is a common theme here.....It does not hold up to well when running any number of routers never mind the INE V5 Topology.

    To all GNS3 users on here who complain about it's shortcomings, tell me how many Routers are you going to be configuring whilst using a GUI during the Lab?  Not many I imagine.

    I would strongly suggest that you all ditch it, along with Windows and run Dynamips/Dynagen under Ubuntu.  It's well documented on Hacki and elsewhere that you will NOT get the same performance levels from using Dynamips under Windows as opposed to any Linux Distro

    I intend on putting a guide together in the next week or so to demonstrate how to install Dynamips on a vanilla install of Ubuntu to help both myself and others which I may post here if interest dictates.

    Installing Dynamips under Ubuntu really is not that difficult at all it's just that there is no one place that pulls it all together and it just works!  Believe me i have looked.

  • Thank you for posting the .net file, I can now start all of the devices...:-)

    Happy Holidays

     

  • I have a problem when starting INE topology v5 in GNS3. I only have 11 devices which can start.Two devices remain unstarted. I have a laptop with CPU  2.0 Ghz Duo Core , RAM 3Gb and I am using Windows Vista Ultimate. Thanks a lot for your help

  • How to change extensions from .txt to .net on Vista Ultimate? Sorry if I am fool. Thank you

  • unzip the attach and save it to the INE folder (replace the topology v5 on that folder with this one).

  • OK I got it.You have to save the file in txt and open the file and go to save as and change the file name with extension .net .

     

    Thank you and sorry about my foolish knowledge

  • hi am sorry,

     me i have a problem with gns3.7, and that am not able to run advance layer2 switching lab, although they mentioned great improvements in gns3.7, am using vista business x32. forgive me if am being fool  

  • Wow, thank you so much.  I've struggled a long time to get this to work.  i used your file and instructions and finally got all devices to boot on my pc.  Thanks again.

  • mna,

    Please keep in mind that although there is a new version of GNS3, the underlying "engine" that emulates the actual routers (dynamips) has not been updated in quite a while now.  GNS3 is only a nice front-end graphical tool that allows you to easily build topologies and push them to dynamips, which actually does the real work. 

    For general Layer 2 troubleshooting steps, start off with statically setting all interfaces to 100/Full.  Also, rebooting the "switches" frequently helps.. 

    There are many, many, many posts on this forum related to Layer 2 dynamips issues.  If my suggestions above don't help, try searching around this forum for more information.  I guarantee you your issue has been addressed AND resolved in a previous post.

    HTH

  • Explain well what you say. I don't understand .

  • Awesome Mady!  Adding the second hypervisor in there made all the difference!  The INE topoligy is working on my server: Quad AMD AthlonII w/ 4 Gig or RAM running Windows 7 64-bit.

    Cheers,
