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 --000000000000b1eec4056fa4a06d Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable
What versio= n of the libvncserver/libvncclient are you building against?=C2=A0

# dpkg -l | grep vncclient
ii libvncclient1= :amd64 0.9.11+dfsg-1+deb9u1 amd64 API to write one's own VNC server - c= lient library


Hmmm....I can&#= 39;t remember if there are any version-specific issues with that version of= libvncclient, but I'd expect the segfault message to happen in libvncc= lient not the Guacamole library, if that were the case.
=C2=A0

=

Any special configuration for VNC?=C2=A0

for the = client, this is nothing special

Are you trying to use enc= ryption?=C2=A0

No encryption

no password, trought= reverse ssh with ssh-key without passphrase
