Drag and Drop issue

Adrian Owen

Guacamole 0.9.12 – Debian Jessie x86

 

On the Guacamole server:

1.       I followed this: https://glyptodon.org/jira/browse/GUAC-513

-          And created the 2 links

 

2.       I created /userfiles with 777 permissions

 

-          Restart Guacamole Server

 

IE Guacamole RDP connection from a Windows 7 workstation to a Windows 2008 Server.

 

Additional connection Settings:

Device Redirection

 

Enable printing – TICKED

Enable Drive – TICKED

DRIVE PATH - /userfiles

 

 

I drag a file from the client desktop onto the Guacamole RDP session.

 

-          On the hidden menu I can now see  the file in uploads list

-          On the guacamole server I see the file in /userfiles

 

But I cannot get the file onto the server.

 

There is no Virtual Drive created on the Guacamole RDP Session server, as per the User Guide.

Opening the file from the hidden menu only shows client drives in the save to.

 

 

Any help appreciated,

 

Thanks, Adrian

You should *never* set permissions to 777.

The drive directory needs only be readable/writable by the user that
the guacd service runs as. Making any directory world-writable, let
alone Guacamole's drive directory, is dangerous. If any account on
your server is compromised, even one with little to no privileges,
your users' files will be exposed.

There is no need to restart anything in this case. You only need to
restart things after upgrading Guacamole itself to a new version, and
then only guacd and Tomcat need to be restarted, not the entire
server.

Do you see any relevant messages from guacd in syslog?

Is drive redirection allowed according to the group policies of the
RDP server in question?

Hi Mike,

Jul 28 17:57:10 guacamole guacd[6591]: Failed to load guacdr plugin. Drive redirection and printing will not work. Sound MAY not work.
Jul 28 17:57:10 guacamole guacd[6591]: Failed to load guacsnd alongside guacdr plugin. Sound will not work. Drive redirection and printing MAY not work.

I see a lot of posts about this error, I will investigate them.

Thanks, Adrian
