[Bug 1412066] [NEW] Cannot configure the vino-server "security type" control

 

Public bug reported:

I was setting up a testcase for gnome's vino server. Vino had to be
tested to confirm it works at the basic level of vnc connection.

Packages installed: vino, xvnc4viewer

After installing vino and xvnc4viewer, in lubuntu, (xubuntu with
lubuntu-desktop installed). The vino-server was started in Lubuntu 14.04
using this following command: /usr/lib/vino/vino-server &. This is the
output of the following command.

(vino-server:16269): WARNING **: Couldn't connect to accessibility bus:
Failed to connect to socket /tmp/dbus-3lXPtqLo8q: Connection refused

(vino-server:16269): EggSMClient-CRITICAL **: egg_sm_client_set_mode: assertion 'global_client == NULL || global_client_mode == EGG_SM_CLIENT_MODE_DISABLED' failed

17/01/2015 04:39:42 PM Listening IPv4://0.0.0.0:5900

I have read multiple tutorials outlining procedures to enable and
connect to a vino-server. In all instructions, "ssh" was used to
establish the connection. This is the form of the command  to connect to
a vino-server.

"ssh -L 12345:localhost:5900 username@ipaddress".

I tried testing vino on my own laptop by connecting to itself.

Whenever I performed the connection with or without ssh, I always get
this output from the server:

17/01/2015 04:19:08 PM [IPv4] Got connection from client localhost
17/01/2015 04:19:08 PM   other clients:

This was after I used the command, ssh -L 12345:localhost:5900
username@ipaddress

I get this output after I typed xvnc4viewer from my local terminal:

 CConn:       connected to host 172.29.24.129 port 5900
 CConnection: Server supports RFB protocol version 3.7
 CConnection: Using RFB protocol version 3.7
 CConnection: No matching security types
 main:        No matching security types

It seems the problem is that I cannot establish a successful connection
unless I am using the same security type. I could not find a way to
configure the vino-server to change or remove the security type. There
was no manpage for the vino-server. A manpage for the vino-server is
needed, updated setup howto for all variants of ubuntu and an advanced
configuration file for the vino-server to modify how it runs and
behaves.
