[jira] [Commented] (GUACAMOLE-414) Certain VNC servers result in disconnection due to TLS errors

    [ https://issues.apache.org/jira/browse/GUACAMOLE-414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16425327#comment-16425327 ]

------------------------------------------

Hi Nick, apologies for the slow response, I saw your first post but missed the second.

 

To answer your questions:
 * I'm using 9.14 binary form the guacamole downloads so whatever that has linked into it would be the libvncserver library it's compiled against. 
 * TightVNC does not support xrandr for dynamic screen resolution, while TigerVNC does.
 * Centos Window manager  was XFCE  and using TigerVNC for dynamic screen res. xrandr is supported.

I'm happy to report that Ubuntu 17.10 (artful release), LXDE and TigerVNC (TigerVNC packages for Ubuntu in 17.10) does seem to work much better:

Apr 4 10:25:09 halhvguac guacd[226820]: TLS session initialized.
Apr 4 10:25:09 halhvguac guacd[226820]: TLS anonymous credential created.
Apr 4 10:25:09 halhvguac guacd[226820]: TLS handshake blocking.
Apr 4 10:25:10 halhvguac guacd[226820]: TLS handshake blocking.
Apr 4 10:25:11 halhvguac guacd[226820]: TLS handshake done.

> Connecting to certain VNC servers such as Ubuntu Desktop (all versions I have ever run) and a CentOS based Browser Docker ([https://hub.docker.com/r/consol/centos-xfce-vnc/]) cause frequent TLS errors and consequently disconnections. The errors in the log are as follows:
> {noformat}
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Error reading from TLS: The TLS connection was non-properly terminated..
> Oct 12 14:54:59 2004ff6050af guacd[8440]: read (4: Interrupted system call)
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Error handling message from VNC server.
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Internal VNC client disconnected
> {noformat}
