HUBERION commented on GUACAMOLE-1862:
-------------------------------------
Hi Mike,
Thanks for your quick feedback. We don't see incoming connection on the RDP
(also not with Packet sniffing).
We can connect with freerdp without any issue to the RDP Server.
How can we debug the connection attempts of the guacd, i would expect to see a
logging like "trying to open connection to IP ..., PORT ....".
I cannot see this in both (SUCCES AND FAIL) logs. We have enabled "debug", do
we need to enable a different kind of logging to see that?
Are we checking the wrong Logfiles?

> Key: GUACAMOLE-1862
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1862
> Project: Guacamole
> Issue Type: Bug
> Components: guacd
> Affects Versions: 1.5.3, 1.5.4
> Environment: OS: Ubuntu 22/04
> GUACD Docker: Ubuntu 22/04 -> same issue on original Docker Image (Alpine
> Linux)
> Reporter: HUBERION
> Priority: Minor
> Attachments: Hanging.txt, Successfuly_after_CTRL-R.txt
>
>
> After creating a adhoc Connection via a custom AuthenticationProvider
> Extenions sometimes (about 20%) of the cases the GUACD hangs and stays in
> this stage with the log "Clipboard data has been received, but cannot be sent
> to the RDP server because the CLIPRDR channel is not yet connected."
> Refreshing with CTRL-R in the browser solves the issue normally. We think
> that the GUACD is not evenen opening a Socket connection to the Remote hosts.
> The Issue exists on all 1.5.X Version, most likely also on older.
> Tested with newest Firefox/Chrome browser.
> Remote Server = Windows 2019.
> RDP Parameters: security=nla, ignore-cert=true, server-layout=de-de-qwertz,
> hostname, port, connectionUsername, connectionPassword
