I am using gns3 version 2.1.8 on Ubuntu 18.04. On loading any IOS image with dynamips installed, i get the following error

Dynamips hypervisor process has stopped, return code: -11
C3745 'Ghost': generic_nvram_extract_config: Unknown error -61605

I have tried with many IOS images and all return the same error. These IOS images used to work in Ubuntu 16.04.

Please note: I installed gns3-gui using the apt-get method from the GNS3 Ubuntu PPA and didnt compile dynamips or any other package separately.

I am also affected by this bug. Glad it's getting attention. Thank you.
This only happens when I install on physical hardware. If I install ubuntu 18.04 in a VM, dynamips doesn't give the error.

We suspect an issue with a library used by Dynamips.

See #84 and #83

Compiling Dynamips for x86 may solve the problem.

I confirm I don't have the issue when running Ubuntu 18.04 in a VM.

Compiling Dynamips for x86 may solve the problem.

Can you try the 32-bit version of Dynamips on physical hardware please?

You can compile it yourself or download it from https://drive.google.com/open?id=16cpF6CP6KuzbXRS2QTcGcST0vcNmvom5 (you still need to install the 32-bit libraries with sudo apt install libelf-dev:i386 libpcap0.8-dev:i386)

To compile from scratch:

sudo apt install libc6-dev-i386
sudo apt install libelf-dev:i386 libpcap0.8-dev:i386
sudo apt install git cmake
git clone https://github.com/GNS3/dynamips.git
cd dynamips
mkdir build
cd build
cmake .. -DDYNAMIPS_ARCH=x86
make
sudo make install

Thanks!

Hi

I tried installing gns3 from the same Ubuntu repos ppa in version 16.04 and everything works. Just curious if it’s something to do with some dependencies specific to 18.04 ?

Thanks

Thanks for your help Jeremy. Hopefully you can assist with a fix now
without going the 32bit route.

Thanks for the feedback. I think we going to stick to the 32-bit route for now since we have no idea how we can fix the 64-bit version at the moment.

Hi Walter

If you could document the steps on how to make this work in Ubuntu 18.04, it would be really helpful.

Thanks for your help

Hi Walter

Thanks a lot. Would try this out. I had to move back to 16.04 just because GNS3 was not working. Now i could happily move to 18.04 :)

Thanks for your help in testing out the recommendations and also for the quick how to :)

I noticed we already build Dynamips 32-bit on our PPA. Something like this should be enough to install:

$ sudo apt update
$ sudo apt install dynamips:i386

once I run sudo apt install dynamips:i386,the dynamips(64) and gns3-gui,gns3-server would be automatically removed.
after installed dynamips:i386, I install gns3-gui back, it said dynamips:i386 will be removed,once choose yes , the dynamips:i386 also would be automatically removed
don't know how to break this dependence

I have try like this :
1, apt remove the dynamips 64 with gns3-gui and gns3-server automatically,
2, Install dynamips:i386,
3, copy usr/bin/dynamips (32bit version ) to another path
4, install gns3-gui and gns3-server , the dynamips:i386 will be removed.
5, use ln -s the dynamips 32 which copied beford,to /usr/bin/dynamips
then run a topo with dynamips device like c3745 it's working.

I think the reason is that dynamips is a dependency of gns3-server. I am considering moving it to a recommendation instead so users are free to install the 64-bit or 32-bit version or nothing at all if they don't need dynamips at all.

Current control file for the gns3-server package is:

Source: gns3-server
Section: net
Priority: extra
Maintainer: GNS3 team <developers@gns3.net>
Build-Depends: debhelper (>= 9), python3, python3-setuptools, python3-dev, dh-virtualenv, python-setuptools
Standards-Version: 3.9.5
X-Python3-Version: >= 3.4, <= 3.6

Package: gns3-server
Architecture: amd64
Pre-Depends: dpkg (>= 1.16.1), python3.4 | python3.5  | python3.6
Depends: python3, vpcs, dynamips, ubridge (>= 0.9.14), qemu-system-x86, qemu-system-arm, qemu-kvm, qemu-utils, cpulimit, x11vnc, xvfb, libvirt-bin | libvirt-daemon-system, ${misc:Depends}, ${shlibs:Depends}
Enhances: gns3-iou
Description: GNS3 server

We would remove dynamips from Depends and add Recommends: dynamips

@ziajka @Ehlers what do you think?

ghost commented Aug 8, 2018

I'm installing GNS3 from source, so the following is just theoretical.

Here a documentation about the dependencies: https://www.debian.org/doc/debian-policy/ch-relationships.html#binary-dependencies-depends-recommends-suggests-enhances-pre-depends

I think, that the gns3-server package depends on packages, that are not really necessary to use the server, so something like the following might be an alternative:

Depends: python3, ubridge (>= 0.9.14), x11vnc, xvfb, libvirt-bin | libvirt-daemon-system, ${misc:Depends}, ${shlibs:Depends}
Recommends: vpcs, dynamips, qemu-system-x86, qemu-kvm, qemu-utils, cpulimit
Suggests: qemu-system-arm

Maybe even x11vncand xvfb might be moved to Recommends as these packages are only used by docker VMs, but that must be verified. Same for libvirt-bin | libvirt-daemon-system, it's needed for the NAT cloud. Is this core functionality or is it only recommended? And what about docker? Currently it's missing.

But the drawback moving package to Recommends or Suggests is, that GNS3 can't expect that these packages are installed. GNS3 must cope with absent packages. I think, that it already does that, but it has to be verified. And it must be clear to the user, that leaving out some packages reduces the functionality of GNS3.

@Ehlers So that shoud make some other support package, just like gns3-docker,gns3-nat-cloud for docker and nat could support.
@grossmj dynamips should be weak dependency.

grossmj commented Aug 13, 2018

I will only have Dynamips as a weak dependency (move it to the recommends field) for now to try to fix this current issue and we will consider moving more things like vpcs and Qemu in GNS3 version 2.2. Also, I think libvirt-bin is a core functionality.

grossmj commented Aug 28, 2018

Starting with version 2.1.9 packages, the Dynamips package is not installed by default anymore.

I installed Dynamips 32-bit on a fresh Ubuntu 18.04 64-bit VM using the following commands and tested with c3725 and c7200 images and got no crash. However, the headache with this Dynamips crash is that it apparently doesn't happen when running Ubuntu 18.04 in a VM. The only thing we can do at the moment is to let our Ubuntu users know about the problem and how to install Dynamips 32-bit as a work around, then get feedback.

sudo add-apt-repository ppa:gns3/ppa
sudo dpkg --add-architecture i386
sudo apt update
sudo apt install dynamips:i386

This issue should be fixed by installing Dynamips v0.2.19. No need to specifically install the 32-bit version or to set the timezone.

You can use the following workaround

wget http://ppa.launchpad.net/gns3/ppa/ubuntu/pool/main/d/dynamips/dynamips_0.2.21-1~eoan1_i386.deb
sudo dpkg -i dynamips_0.2.21-1~eoan1_i386.deb
sudo apt --fix-broken install

Maybe someone can suggest a better way to install the dependencies, but it works.
