Trying to establish SHH connection with Key authentication = You
have been disconnected
Hello
I am having difficulties setting up a SSH connection with key
authentication. First of all, with password authentication it works just
fine. When trying to use key authentication I assume when checking the logs
I can successfully authenticate and establish a connection but then get
immediately get disconnected with the message in Guacamole: "You have been
disconnected". I have attached logs from Tomcat, ssh-logs of the machine
receiving the connection as well as the guacd status log.
Also my setup: I am using an apache proxy to connect to guacamole (same
machine).
Attached files:
tomcat.log
<http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/file/t816/tomcat.log>
ssh-log.txt

I cannot get the official docker image to work on my Raspberry as the sql
image refuses to get downloaded, it doesn't seem to be supported with ARM.
I also found this: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888973
which I think relates to my issue. I will open an issue ticket on the github
I have the docker image from and maybe in the future switch OS and run it
virtualized on a x86 machine.
Thanks for the help

With a different error message and different logs, you are encountering a
different issue.
I have used docker and this image:

Have you tried using the images produced by the project itself?

I don't know that this has any bearing on your issue, but beware that we
don't maintain the image you are currently using; it's maintained by a
member of the community.

What do you see in the Tomcat logs?

Ok really disappointed as the issue is continue happen even though I am now
running the latest version. I have used docker and this image:
https://github.com/oznu/docker-guacamole ( I am running on armv7)
Now when trying to establish an SSH connection with PKA, I cannot get access
the terminal even though everything succeeds. A screenshot is provided

. I run raspbian as OS and my private key length is 4096bit.

Maybe it's worth mentioning: I have installed guacamole using this guide:
https://wiki.debian.org/Guacamole but I just realized that the version I
installed from the Debian Package ( apt install guacd -y) is v 0.9.9 and
that is many years old.
What would be the solution to upgrade to the latest version?

I have converted the private key with putty and tried to login, it works.

I hope I have done this step since I am not very experienced: I created a
guacd.conf file in /etc/guacamole and inserted following:
[daemon]
log_level = debug
And rebooted the system. Now when trying it again, it spits out following:

If you use that same private key file from the command line to log into the
same target SSH system, with the same username, does it work?
Can you start guacd in debug logging mode (-L debug) and post that log back?
