channel 2: open failed: unknown channel type: unsupported channel type about remote-kubernetes HOT 9 CLOSED

How did you get your Okteta:Up to work? Mine fails at that command.

from remote-kubernetes.

Easy: It just worked....until it didn't :)

thanks for reporting, we're looking into it! What kubernetes version distribution are you using @stefanfritsch @waddahAldrobi ?

from remote-kubernetes.

@rberrelleza thanks for looking into it.

The cluster was created with rke 1.2

from remote-kubernetes.

I also tried it with a k3s cluster. Same issue

from remote-kubernetes.

we haven't been able to replicate this issue. Could you try and see if it still reproduces with the version 0.3.4 of the extension? If it does reproduce, could you share your $HOME/.ssh/config file with us, as well as the version of your SSH client?

from remote-kubernetes.

Sorry this took so long:

ssh-version

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Application     ssh.exe                                            8.1.0.1    C:\WINDOWS\System32\OpenSSH\ssh.exe

.ssh/config

And the entry in .ssh/config is

# entry generated by okteto
Host hello-world.okteto
  ForwardAgent yes
  PubkeyAcceptedKeyTypes +ssh-rsa
  HostName localhost
  Port 22100
  StrictHostKeyChecking no
  UserKnownHostsFile /dev/null
  IdentityFile "C:\Users\StefanFritsch\.okteto\id_rsa_okteto"

Everything else in .ssh/config are other host directives that do not conflict with this one.

New developments

VPN

The connection is through a wireguard VPN which might be the problem? But using ssh-remote to other servers over the VPN works fine.

ssh-connection

The ssh-connection itself is fine. I can connect to the container from a powershell window using the .ssh/config entry. I

PS C:\Users\StefanFritsch> ssh hello-world.okteto

Welcome to your development container. Happy coding!

Error message

The error message has changed slightly since the last time. It now also complains about "channel 3", whatever that is.

The following error notification is also new (although I'm not yet 100% certain it's okteto as some extensions just got updated):

Failed to connect to the remote extension host server (Error: WebSocket close with status code 1006)

from remote-kubernetes.

This is fixed in the 0.4.1 release

from remote-kubernetes.

@rberrelleza today I had the opportunity to try the extension again and it's still broken in 0.4.3. Both with Windows ssh 8.9 as well as with git ssh 8.8 (see below)

Same issue as before:

The ssh tunnel terminal

Current OS

• OS: Windows 11 21H2
• SSH: OpenSSH_for_Windows_8.9p1, LibreSSL 3.4.3

I also tried it using the ssh of git bash (C:\Program Files\Git\usr\bin\ssh.exe):

• SSH: OpenSSH_8.8p1

With WSL2 it doesn't work because okteto only listens on localhost and is not accessible from WSL2 afaics.
