Validating configuration hangs on IPv6

[Tridie2000]

When I add an IPv6 address to the ssh_allowed_networks or api_allowed_networks blocks, the tool hangs at "Validating configuration..."

ssh_allowed_networks:
  - 0.0.0.0/0
  - ::/0

api_allowed_networks:
  - 0.0.0.0/0
  - ::/0

hetzner-k3s --version => 1.1.5
macOS => 14.0

I haven't done any testing with ipv6 unfortunately.

Hi @Tridie2000 - did you get it working eventually?

[dperetti]

Same issue for me.

[Tridie2000]

No, I did not get it working with IPv6 addresses.

I noticed the same issue (when trying to provision a "pure IPV6" cluster). I'm going to try and investigate further.

As I started to debug the issue, I noticed that if I build from source, hetzner-k3s doesn't hang anymore at "Validating configuration...", at least on my test configuration,.

I checked by trying exactly the same cluster configuration, on the same machine, with the same SSH keys etc. (to make sure the problem wouldn't come from e.g. an SSH agent, like suggested in #320 ), and with the 1.1.5 release downloaded from GitHub, it hangs at "Validating configuration..." while with the version that I just built from main, it doesn't hang.

I suppose there could be two possible issues:

• a bug in the older version of the code, that was fixed since then
• a subtle difference in build environment

For what it's worth, I've built inside the dev container. I'm going to document how to run and build with the build containers if other folks want to try and see if that helps.

Edit: provisioning over IPv6 doesn't work; but for different reasons. I'll open a separate issue about it.

@jpetazzo in main I upgraded the ssh2 shard, so it's very likely that the new version addresses some issues with SSH. Nice to hear that you couldn't reproduce it with main. I will release v2.0.0 as soon as I have finished work in #348.
