ubridge 0.9.16 (GNS 2.2.5) doesn't work with tap interfaces on OS X

I am having a problem with the same issue as Issues # 55. Issues #55 did n’t give me a solution, Please check again. How can I connect?

Have solved this problem？I met the same problem with you.

I'm facing the same issue. I'm using GNS3 2.2.22 on MacOS Big Sur.

A suggestion for you guys would be to run everything on top of Linux. I do, and everything works smooth.

I also tried the same on a Fedora 32 and got the same error. I'm pretty sure I got this working on OS X sometime in 2019. I upgraded to 2.2.22 yesterday and it started failing.

Is there any other option to SSH from my local host to the GNS3 devices?

Hi,

I am running GNS3 2.2.21 on Fedora 34 and GNS3 2.2.22 on Ubuntu 20.04 LTS, and the TAP NICs work properly on both.

I am sharing the commands I use to start / create a TAP NIC on demand.

ip tuntap add tap0 mode tap ip link set dev tap0 up ip address add 192.168.1.1/30 dev tap0

I will add that the next major version of GNS3 will require Linux (not for the user interface but for the server).

@grossmj FYI, All the appliances are running on a remote GNS3 server on top of Ubuntu 18.04. I'm just connecting to those from the OS X GNS3 client.

The same issue exists in Fedora33 with Gns3 version 2.2.21, even tried upgrading 2.2.22.

Hi,

My point is to encourage people to run Linux on bare-metal. Personally speaking, I run on my two laptops, and I never have the kinds of struggles I see very often people unable to do many things. However, I am not saying Linux is better and /or BSD or Windows are worse and so. The thing is like to create a list of what are my needs as user, and what OS fits better to the user, and keeping in mind nothing is perfect.

On the other hand, GNS3 is the best framework I have used, and I have tested a few available on the market. Keep doing what you do, that you and you team are AWESOME.
