Hmmm....I can't remember if there are any version-specific issues with that version of libvncclient, but I'd expect the segfault message to happen in libvncclient not the Guacamole library, if that were the case. > Any special configuration for VNC? > > for the client, this is nothing special > > Are you trying to use encryption? > > No encryption > > no password, trought reverse ssh with ssh-key without passphrase > > Jun 27 16:10:34 pulsemaster kernel: [717204.421339] guacd[28944]: segfault > at 10 ip 00007f9ead26c692 sp 00007f9eaec7ad10 error 4 in > libguac-client-vnc.so.0.0.0[7f9ead264000+13000] > At this point I'd probably need a core dump or gdb stack trace to track down the issue. You can see if any of the following issues match the scenario you're running into: https://issues.apache.org/jira/browse/GUACAMOLE-424 https://issues.apache.org/jira/browse/GUACAMOLE-428 Those issues are related - one deals with VNC password issues, but it looks like the fix takes care of at least a couple of scenarios. It looks like that's not fixed in the 0.9.14 code but will be in the 1.0.0 code, so you could try building guacd from the git repo, either the master branch or the staging/1.0.0 branch. -Nick
