vnc guacd segfault after upgrading from 0.9.10 to 0.9.12
Hello,
after upgrading from 0.9.10 to 0.9.12 I can no longer connect via vnc.

Any Idea ?

Hello,
sorry for the delayed Information.
1) yes, guacamole packages have from the Distribution are not installed
(apt list --installed |grep gua does not Show anything related)
2)
root@guacamole:/var/log# ldd /usr/local/sbin/guacd | grep guac libguac.so.12 => /usr/local/lib/libguac.so.12 (0x00007f41922f7000)

Thanks, Philip

Betreff: Re: vnc guacd segfault after upgrading from 0.9.10 to 0.9.12
1) Can you confirm that you haven't installed Guacamole packages
provided by your distribution? Such packages would conflict with the
result of the build, resulting in guacd loading older,
binary-incompatible versions of its protocol support plugins.
2) What is the output of:
ldd /usr/local/sbin/guacd | grep guac
and:
ldd /usr/local/lib/libguac-client-vnc.so | grep guac
?
Thanks,
- Mike

Hi Mike,
thanks for the hints!
RDP performs magnitudes better for us than VNC.
The Windows server crashing was indeed an issue caused by the VNC server we
used. But as we switched to RDP, that's no issue any longer.

Nope.
Otherwise, it may just be a UltaVNC issue. Do you have a recommendation for

The manual has a summary of some VNC servers and their pros/cons:
http://guacamole.incubator.apache.org/doc/gug/configuring-guacamole.html#vnc-servers
If possible (e.g. on Windows clients), should we rather use RDP

If connecting to Windows *servers*, RDP would be better, but a browser
running on Windows is no different to Guacamole than a browser running on
Linux (or Android ... or iOS ... or OSX ... etc.).
Further, the difference between the protocols exists only server-side. From
the client's perspective, everything is just Guacamole protocol. The main
difference between VNC and RDP in the case of the client is that RDP
provides some performance features which VNC lacks, like bitmap caching,
and Guacamole can leverage analogous features of its protocol to provide
the same.
To the Guacamole server, all clients are the same. To the Guacamole client,
all protocols are the same.

We had another similar issue, but only when reverse connecting from a Windows
Server 2016 (with the latest UltraVNC).
Is guacamole somehow handling VNC clients differently based on OS?
Otherwise, it may just be a UltaVNC issue. Do you have a recommendation for
VNC servers? If possible (e.g. on Windows clients), should we rather use RDP
or that VNC recommendation?
Thanks a lot!

Hi Mike,
thanks for the quick response! Just checked out master from git. Works
splendidly :-)
Have a great week!
Kind Regards

Please try a recent build from git. There is a recently-fixed issue which
could result in these symptoms:
https://issues.apache.org/jira/browse/GUACAMOLE-306
