Can't connect to raspios - "unknown security types"

[MrButlerTron]

Anyone have suggesstions - trying to use vncdo from my Mac to a Raspberry Pi and I'm getting "unknown security types"

INFO:twisted:Starting factory <vncdotool.command.VNCDoCLIFactory object at 0x107342cf0>

command:
vncdo -v -s hosname-u pi -p 'raspberry' capture screenshot.png

Please provide more details, e.g. which VNC server are you running on your RPi including the version.

[MrButlerTron]

Sure, thanks for the response.
I'm running wayvnc on what I think is the latest version of the RPiOS.

 :~ $ wayvnc --version
wayvnc: 0.9-dev
neatvnc: 0.9-dev
aml: 0.3.0
:~ $ cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"

The latest version of Raspberry Pi OS is PRETTY_NAME="Debian GNU/Linux 13 (trixie)" and the wayvnc version is now:

$ wayvnc --version
wayvnc: 0.9.1
neatvnc: 0.9.5
aml: 0.3.0

But FWIW, I also get the same error when trying to connect to that with vncdo 1.3.0:

$ vncdo -vv -s my_pi_hostname -u my_pi_username -p my_pi_password type hello
INFO:root:connecting to my_pi_hostname:5900

TigerVnc is able to connect to the same wayvnc server just fine.

...and in case it's helpful, here's the default /etc/wayvnc/config file on Raspberry Pi OS:

use_relative_paths=true
address=::
enable_auth=true
enable_pam=true
private_key_file=tls_key.pem
certificate_file=tls_cert.pem
rsa_private_key_file=rsa_key.pem

(with the rsa_key.pem, tls_cert.pem and tls_key.pem files also being present in /etc/wayvnc/)

Someone™ needs to pick up the specification and has to implement one of those authentication methods:

• <AuthTypes.VENCRYPT: 19>
• <AuthTypes.RSA_AES256: 129>
• <AuthTypes.RSA_AES: 5>

None of the methods supported by vncdotool is accepted/offered by wayvnc; see vncdotool/rfb.py:154 SUPPORTED_AUTHS = { NONE, VNC_AUTHENTICATION, DH }

1. Implement one of those methods
2. Hook it in to _handleSecurityTypes()
3. Add it to SUPPORTED_AUTHS
