RDP session fails if SFTP is not available
Hello, We are using Guacamole to access RDP servers and we are using file transfer with SFTP protocol (RDP+SFTP configuration). Sometimes it happens that SFTP server is not available/reachable and in that case Guacamole drops the whole connection. Is it possible to still have RDP connection in the case when SFTP server is configured in parameters, but the actual server is not available? Something like failback from RDP+SFTP to RDP only. Such connection would have reduced functionality compared to what is requested in the parameters, but I think from the user perspective this is still better than having no connection at all. Regards, Marko
Re: Guacamole login page customization 0.9.12
It is possible to customize guacamole in this way, but it will essentially result in the custom release of Guacamole. Any upgrade to the new Guacamole release will require repeating of this procedure. On the other side, extensions are not that much dependent on the guacamole version and upgrades (but for sure requires testing before production).

Re: Guacamole login page customization 0.9.12
Hi Goncalo,
It is the extension format for the path, you don't need to create
app/ext/V2SLABS path. You can find the format description here:
http://guacamole.incubator.apache.org/doc/gug/guacamole-ext.html#ext-file-format
Look at the manifest table and check the "resources" row.
Regards,
Marko

Setting sftp-directory ignored
Hello, I am connecting to remote machine using RDP+SFTP and the file transfer over SFTP is working correctly, including programatically uploading files to different directories on the destination machine. However, I am not able to set sftp-directory for files dropped on desktop; any value set there is ignored. The files uploaded via drag&drop are always saved to the SFTP default directory (root directory in my case). Is there something else that has to be set? I have checked the code in the client, the handler for "drop" event in guacClient directive (guacamole/src/main/webapp/app/client/directives/guacClient.js) is just calling uploadFile without specifing filesystem and directory to upload to; I guess in that case files are sent to default fs/directory. Am I missing something else here? How is sftp-directory parameter handled? Thanks, Marko

Changing error dialogs
Hello, I would like to customize the functionality of the error dialogs in the Guacamole client application within the extension I am developing. Changing the dialog texts and the styling of the dialogs are not sufficient for my use case. I found that the error handling dialogs are displayed from the clientController.js file, but I don't want to change original code; I want all customization to be within extension. Is it possible to somehow override the funcionality contained in clientController from extension? Thanks, Marko

Guacamole with broker
Hello, We are planning to use Guacamole with connection broker, where the broker should redirect the connection to server farm and start application on one of the servers. Is something like this possible with guacamole? We are able to make connection to the broker, but redirected app fails and we get a black screen. Regards, Marko
Two desktops in parallel
Hello, I am using Guacamole 0.9.10 and I was trying to make two (or more) different desktops (or applications) running each in separate browser tab. However, I can connect within one tab, and the another tab is always the same as the first one, I even does not get the login prompt in the second tab. When I try with incognito window, it is possible to connect to the second desktop. However, I would prefer if this could be possible within two "normal" windows. I was trying with SimpleAuthProvider and with JDBC MySql provider, but without success. Is scenario like this one supported at all? Thanks and regards, Marko
Connection close
Hello, I am writing an java extension on the server side that should detect when the connection is closed, either by using Logout or closing the browser window. I have found TunnelCloseEvent/Listener in the Java API, but it seems that it is not used any more. Is there some other method for detecting connection close event within extension? Thanks and regards, Marko
Re: SFTP file locking
I have made some short testing and it seems that thare are no more problems with file locking. Beside the above, I had issue with failing to connect to some of the servers when SFTP is turned on, with error message "Error waiting for file descriptor." (0.10-incubating). Somehow, this happens on some servers, on some don't, but with the latest code, everything work. Marko пон, 27. феб 2017. у 00:27 Marko Nikolić је написао/ла: Thanks for the quick response!

Re: File browser / prevent download
In short, client is using software running on VPS via RDC. The service provider adds some propritery data files to this software (that is what the client is actually paying for). The client should not have ability to download those files. On the other side, client can make it's own data files and upload them to VPS. This is the reason why upload should be possible and download prevented.

File browser / prevent download
Hello, I have a specific request for using guacamole file browser and putting restrictions on file transfer. The user is accessing the server using guacamole via RDP and it is required to allow uploading of files, but to prevent downloading. I have tried to set the permissions on the *drive-path* but it didn't work, either it disables file transfer completely or it works in both directions. Maybe I have missed something here. Is it possible to implement this functionality using extensions? I couldn't find much documentation about creating extensions, only some basic examples for UI customization. What would be the correct approach for such functionality? Thanks, Marko
