1 year ago This is not enough information to help you, as the problem way well be with your setup.
Please test with vncdo -v -s 192.168.178.111 -p 'raspberry' capture 'screenshot.png' first and also make sure, that you can actually connect to IPv4 address 192.168.178.111 TCP port 5900 and that it is not blocked by any firewall rule and that the VNC server running there actually binds to a public interface — loopback lo is not enugh.
To test this use some low-level tool like netcat and do a nc 192.168.178.111 5900: you should see some RFB 003.008 string printed — if not, investigate your network first.

1 year ago hi ican use the pi with vnc that works.

1 year ago INFO:twisted:Protocol version 5.000 not supported
That is not a valid/supported VNC/RFB protocol version.
and this is the nc output:
What follows is the output of nmap not netcat. Please use nc or netcat or telnet or whatever tool to open a TCP connection to your host on TCP port 5900 and return its output, which should start with RFB 003.

1 year ago RFB 005.000 ist the output over telnet if i tried on a other pi i becam this error:

1 year ago RFB 005.000 is a completely new protocol: each new version might add new messages or may change the semantics of previous messages. Because of that any VNC client must understand all messages associated with that version. If the client receives an unknown message the only reasonable things any client can do is to terminate the connection.
vncdotool only supports the following versions:
003.003, 003.007, 003.008 which are described by RFC 6143, which is available public.003.889 is an extension from Apple; no public spec available, but luckily close enough to 3.8Several companies extended RFB as specified in the RFC on their own, but never provided a public specification for their changes, which anyone can access for free:
004.000 is used by Intel AMT KVM004.001 is RealVNC 4.6 (the company, which invented RFB, but they only ever opened and published their old version in said RFB, but all further versions are proprietary)005.000 is RealVNC 5.3The current code already limits the supported version to 003.008 — albeit it is printed as 3.800 above, which is already fixed in the latest version currently in git — but then only unknown authentication types are offered, which vncdotool does not understand and thus does not support:
INFO:twisted:Protocol version 5.000 not supported
INFO:twisted:Using protocol version 3.800
INFO:twisted:unknown security types: (13, 5, 6, 130, 192)non of them are supported by vncdotool — not even the version currently brewing in git branch main — so the client and server cannot agree to a common authentication mechanism and the client has to abort the connection.
vncdotool version 1.0.0
That version is way to old; you should try pip install git+https://github.com/sibson/vncdotool.git@main, which might also fix your 2nd problem
builtins.TypeError: unsupported operand type(s) for &: 'str' and 'int'
Please include the following information:
vncdotool version 1.0.0
from vncdotool import api client = api.connect('192.168.178.111', password='raspberry') client.timeout = 10 client.captureScreen('screenshot.png') client.disconnect()
and this ERROR:
