I am still struggling on how to run guacd in debug mode (step by step manual on how to add -L debug) smiley image="anim_handshake.gif"/> BUT it seems that i have found the cause of my problem and i tend to think that it could be bug that needs to be fixed. Long story short. I am from russia and the PC i was trying to connect via VNC protocol had cyrilic letters in its name (Windows default settings suggest such naming scheme SOMETHING-ПК (PC in russian letters)) and that was what caused connection problems. When i removed cyrilic from PC name, everything works fine. But since it is Microsoft default naming scheme and i suspect it is implemented in other countries -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/

Re: VNC connection problem
Here is a link to folder wiht screenshots and catalina.out https://drive.google.com/open?id=1xJJfa2aitw6k5eLRUeHaGI-_MwVBePF- good is connection "1" bad connection "2" as for running guacd in debug mode and where to find logs of server i would much appreciate some more help ie console commands how to run it in debug ^^ and where to look for log files. as for my docker question the lines in manual just plain dont do anything if you copy|paste them in terminal as they are not accepted as correct command i understand that "\" symbol is equal to CRLF but this way $ docker run --name some-guacamole \ --link some-guacd:guacd\ ... -d -p 8080:8080 guacamole/guacamole or $ docker run --name some-guacamole --link some-guacd:guacd ... -d -p 8080:8080 guacamole/guacamole this is not recognised as correct command -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/

If you're posting from Nabble (looks like you are), and you try to put screenshots inline in the message (insert pictures), the Apache list server tends to strip these out. I think you can attach them instead of inserting them inline, or you could upload them somewhere temporary and paste a link to the image. You also might want to provide full logs for both guacd (in debug mode, using the "-L debug" startup flag) and the Guacamole Client (catalina.out) so that we can look and see if anything looks amiss. > Ok i am trying this another way via docker now and maybe someone can > explain > me what does this mean or how to type it in terminal: > > $ docker run --name some-guacamole \ > --link some-guacd:guacd\ > ... > -d -p 8080:8080 guacamole/guacamole > This should run the Guacamole client container in Docker, and should link the guacd container such that the networking functions in the Guacamole container can access the guacd daemon inside of its container.

Re: VNC connection problem
Thats why i posted screenshots.. Ok i am trying this another way via docker now and maybe someone can explain me what does this mean or how to type it in terminal: $ docker run --name some-guacamole \ --link some-guacd:guacd\ ... -d -p 8080:8080 guacamole/guacamole These lines was taken from guacamole docker setup manual, but they dont work if you copy|paste them or type in. I understand that it may be wy to easy to cover it in manual, but still why it can be presented the way you can use it? -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/
Re: VNC connection problem
As Nick suggests, please verify that you are not accidentally configuring the connection to attempt to connect to the VNC server as if it is guacd. The fields in the web interface for the guacd hostname/port and the VNC server hostname/port are fairly close together, so this would be an easy mistake to make. If you did accidentally specify the VNC server hostname/port for the guacd hostname/port, the protocol error you see in catalina.out is exactly what would be expected. - Mike On Sep 19, 2018 14:02, "VolandSZ" wrote: Any ideas? -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/

I use MySQL authentication and have no problems with all VNC connections that are in the same network Guacamole server is 192.168.1.10 and all connections that are set up in this network are ok (192.168.1.7, 192.168.1.115 and so on) but when i try to connect to 213.30.130.141 i get error described above.

So, instead of Guacamole Client -> guacd -> VNC, it's trying to do Guacamole Cient -> VNC. Can you describe how you're configuring the connection? Are you using basic file authentication, JDBC, LDAP, etc.? Can you post the configuration - either the file configuration or a basic screen shot of the JDBC configuration? -Nick
