RE: Drag and Drop issue - RESOLVED

Adrian Owen
Hi Mike,

I ran these commands:

ln -s /usr/local/lib/freerdp/guacsnd-client.so /usr/lib/i386-linux-gnu/freerdp
ln -s /usr/local/lib/freerdp/libguac.so /usr/lib/i386-linux-gnu/freerdp
ln -s /usr/local/lib/freerdp/guacdr-client.so /usr/lib/i386-linux-gnu/freerdp

And restarted guad


Now G: drive appears on Client.

Many 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?

Thanks,

Note that there are other plugins installed, like guacai-client.so
(used for audio input where available). To cover everything, a simpler
approach would be:

    ln -s /usr/local/lib/freerdp/guac*.so /usr/lib/i386-linux-gnu/freerdp/

It's worth noting that the reason what you were doing earlier was not
working was that the FreeRDP libraries were not present in
/usr/lib/x86_64-linux-gnu but rather /usr/lib/i386-linux-gnu. Though
the former path would have been correct on 64-bit Debian, the path on
32-bit Debian is different. The path will vary across distribution as
well, so when in doubt, a good first step is to locate libfreerdp*.so
- that will determine the base path of where the "freerdp"
subdirectory needs to be, which may not initially exist.

There is no "/usr/local/lib/freerdp/libguac.so", nor any need to have
a copy of libguac.so present in FreeRDP's plugin directory. The system
linker will find it in the system-wide location to which it was
installed. Adding this symbolic link will have no effect.

There is no need to restart guacd for this. You only need to restart
guacd after upgrading to a new Guacamole version.

Glad to hear it.

Thanks,
