No data returned from 127.0.0.1:51477, uBridge process running: True #1289

From GNS3 community forum:
https://gns3.com/discussions/ubridge-process-running-true

Hi
Opening GNS3'project (2.1.0, Win10 x64) after one month i see suddenly this stupid error:

No data returned from 127.0.0.1:51477, uBridge process running: True

What is that ? I'm not able to open my project because of that.

Noticed prior tickets with the same errors:
#275
#976

grossmj · 2018-02-09T07:00:04Z

We need to check the output of uBridge. The log file is ubridge.log and there is one file for each node.

… data and are still running. Fixes #1289

…hypervisors. Fixes #1289.

…ixes #1289.

grossmj · 2018-03-07T12:43:28Z

This should fix the problem.

abner19 · 2018-03-20T05:06:24Z

Hello, where can I find the solution for this..?

Thanks,
Rick

grossmj · 2018-03-20T05:07:05Z

@abner19 please download and install GNS3 version 2.1.4

abner19 · 2018-03-20T05:09:47Z

Hi, I'm running ver 2.1.4.. Win 10

grossmj · 2018-03-20T05:11:21Z

Can you reproduce the issue every time?

abner19 · 2018-03-20T05:13:06Z

Thanks for the swift response. Started working after the 5th try or so, beats me...

grossmj · 2018-04-16T08:42:11Z

This time I found the source of the problem. Should be good now.

light-foot · 2018-04-21T18:59:03Z

I find this problem is not fixed. I've got 4 MikrotikCHR's hooked together and when I try to put NAT to one of them I get Error while creating node: No data returned from 127.0.0.1:55459, uBridge process running: True
Error while creating node: No data returned from 127.0.0.1:55466, uBridge process running: True
Until I've tried about 5 times then it works. It's almost as if it's trying ports that are not working because every error has a randomized port and eventually one works.
I'm running GNS 2.1.5 and GNS VM 2.1.5

grossmj · 2018-04-24T09:49:09Z

Do you get the error when you try to link one of your Mikrotik node to a NAT cloud? Please post some screenshots if you can.

Thanks,

light-foot · 2018-04-27T20:52:23Z

Sorry for the wait I was away from networking the last few days. For whatever reason it works every time I’ve tried it today. When it was happening it would do it on both the NAT and Cloud, but only when I select my Desktop as the server and not GNS-VM.

Thanks for the feedback. Was it happening when you dropped the NAT or Cloud node in the drawing area?

light-foot · 2018-04-28T15:59:49Z

It would happen when I dropped the cloud or nat in the draw area and had selected Desktop-"mydesktop" for the server and hit ok. It would never do it when selecting the gns3vm for a server though. ⁣Sent from BlueMail

@grossmj have you any further news on this ?

grossmj · 2018-09-25T09:58:24Z

@sixshakybones version 2.1.10 may have fixed this problem. Can you confirm this since we cannot reproduce that issue on our side?

Thanks! :)

sixshakybones · 2018-09-25T10:13:57Z

Thanks, I have tried that. Good news is I haven't got the message bad news is I got this message.
A quick google search does not bring up any results.

Error while creating node: GNS3 controller version 2.1.10 is not the same as compute server GNS3 VM (GNS3 VM) version 2.1.9

EDIT: Apologies, it just struck me, I guess I need to download the new VM version too... I will provide an update after downloading and reconfiguring the new VM

grossmj · 2018-09-25T10:42:38Z

Oh this means you must upgrade the GNS3 VM to version 2.1.10 (upgrade entry in the menu).

PERFECT !!! Its working, You have made me so happy, thanks for all your development efforts !

I did get one error message popup but it does not seem to have affected the VM startup.
When starting the first virtual machine this error comes up : Could not determine uBridge version for C:\Program Files\GNS3\ubridge.EXE

grossmj · 2018-09-25T21:10:01Z

@sixshakybones do you get this error message everytime?

sixshakybones · 2018-09-26T11:48:28Z

@grossmj I have tested, yes it does. It happens each time starting a virtual machine, 3 times if I have 3 VM's. They all start however.

error while starting Win7ProX86-Attacker-1: No data returned from 127.0.0.1:62989 after sending command 'hypervisor version

I cant add a cloud to the network using the host system as the option from the menu provided once the cloud is dragged into the project.

grossmj · 2018-10-03T12:58:44Z

@sixshakybones I can't figure out what is the problem. Would you mind if I take remote control of your computer using Team Viewer so I can debug that issue? Please contact me on developers@gns3.net to discuss a time and exchange information.

Thanks!

grossmj · 2018-11-26T08:23:48Z

Switched to Python 3.5 on Windows to see if this issue can be resolved since this could possibly be a bug with asyncio. Another possible solution could be to implement asyncio.Protocol to communicate with uBridge but I am reluctant to do it for 2.1.x

byunkook · 2019-02-16T01:48:22Z

Looks like this is still an on-going issue. I do have the same issue on the lastest version 2.1.12.

grossmj · 2019-02-16T02:39:51Z

@byunkook do you confirm this happens only with VirtualBox and VMware nodes?

byunkook · 2019-02-16T02:54:42Z

I'm using VMs in VMware and this is only happening to VM nodes.
This is the exact error message
No data returned from 127.0.0.1:54925 after sending command 'hypervisor version' uBrdige process running:True

I use vmware for GNS3 VM.

When I tried to start a VirtualBox VM node, I get the following error.
"error while starting macOS-1: Cannot start VM because hardware virtualization (VT-x/AMD-V) is already used by another software like VMware or KVM (on Linux)

I never tried GNS3 with VirtualBox GNS3 VM and a VirtualBox node.

byunkook · 2019-02-16T04:37:21Z

FYI, uninstalling VirtualBox fixed the issue.
I no longer get error messages on VMware nodes

I don't understand why installing VirtualBox would interfere and trigger such error on VMware VMs in GNS3 project. I didn't run it. It wasn't running in the background either.

grossmj · 2019-02-27T12:24:54Z

Please can you try version 2.1.14 to check if the problem is still present? Thanks :)

byunkook · 2019-03-02T13:51:31Z

It's better now. I don't get those reported error messages when I start VMware and Virtualbox VM.

Here's new one from .14.
If Virtualbox VM in the project is running on the host already, and if I choose the project to launch, I get below error.

=> VirtualBox has returned an error:

Once I stop the Virtualbox VM, then I can open the project.

With VMware VM, GNS3 doesn't behave this way, it doesn't care if VMware VM in project is running standalone.
