Originally created by @jviotti on GitHub (Jun 24, 2020).

I'm following the instructions and running the VM by port forwarding the SSH port -p 50922:10022, however I can't get a shell on the VM at localhost from the host as the connection is refused and nmap doesn't show the port being open.

Am I missing something?

I'm following the instructions and running the VM by port forwarding the SSH port `-p 50922:10022`, however I can't get a shell on the VM at `localhost` from the host as the connection is refused and `nmap` doesn't show the port being open. Am I missing something?

ssh localhost -p 50922
You also have to turn on system sharing once you've installed the OS
Its under "remote login" in OSX settings

I see. It would be nice to mention this in the docs! Thanks!

I'm afraid I can't make it work yet. I enabled remote login in macOS, and I can ssh to the VM from within the VM at port 22, but 50922 never gets forwarded to the host.

docker ps
See if you have anything else using that port

Did you copy the ports exactly as they are in the readme and/or top of the docker file?

localhost:50922 goes to container:10022 which goes to guest:22

@sickcodes This is the output of docker ps. I'm not very familiar with Docker but I would have expected to see something in the PORTS column:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
e082f90113ab        catalina            "/bin/sh -c 'ls -la …"   25 hours ago        Up 25 hours                             competent_bassi

And I'm running the image as:

docker run \
  --privileged \
  --net host \
  -p 50922:10022 \
  -e "DISPLAY=${DISPLAY:-:0.0}" \
  -e RAM=6 \
  --cap-add=ALL \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  -v /dev:/dev -v /lib/modules:/lib/modules \
  -v /var/run/libvirt/libvirt-sock:/var/run/libvirt/libvirt-sock \
  catalina

The corresponding line from Launch.sh is also correctly substituted with envsubst:

-netdev user,id=net0,hostfwd=tcp::10022-:22, -device e1000-82545em,netdev=net0,id=net0,mac=52:54:00:09:49:17

And remote login is enabled:

@sickcodes I was able to connect to it by omitting the --net host option in docker run. The port is bound and I can see that in docker ps, however the VM has no internet connection now :/

@sickcodes Any clues about this? I've been trying some long shots, but I feel that I'm mostly in the dark. I'm following the instructions exactly as described in the README, so it must be something in my host system, right?

@sickcodes I think got to the bottom of it. The DNS requests would get blocked by firewalld on my Fedora 32 system. See this snippet from docker0 after trying to ping google from within the container:

Things work again if I set docker0 to the trusted zone:

firewall-cmd --permanent --zone=trusted --add-interface=docker0
firewall-cmd --reload
