Linux Desktops

Hi All,
I am not able to use DameWare mini Remote Control to access Tighervnc in Redhat 7 but it working fine with CentOS 8.
some information.
firewall is off
SElinux is permissive
install Tigervnc
our config for vncserver:
[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=simple
User=dbvnc
PAMName=login
PIDFile=/home/dbvnc/.vnc/%H%i.pid
ExecStartPre=/bin/sh -c ‘/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :’
ExecStart=/usr/bin/vncserver %i -geometry 1024x768 -alwaysShared -fg
ExecStop=/bin/sh -c ‘/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :’

[Install]
WantedBy=multi-user.target

When try connect to Redhat 7 using Dameware i got dialog message say:
( This VNC server requires VNC authentication. Please enter the VNC credentials in the Remote Connect dialog)

i try also to run command: # gsettings set org.gnome.Vino require-encryption false
got message say:
(process:64365): dconf-WARNING **: 16:37:15.242: failed to commit changes to dconf: Cannot autolaunch D-Bus without X11 $DISPLAY

any help!

Hi Ali,

The error message you describe sound like configuration issue. Can you show us your vnc configuration file (without any sensitive information)?

hi Sandmann,
i already shared with you the vnc config and i don’t have any other file code configuration.
i am using from my Windows PC a DameWare mini remote connection in that application i just add the vncserver IP address and secret password.
as I told you the same setup and configure work with CentOS system but this message for Redhat 7 system.

Many thanks.

hi all,

I resolved this issue in CentOS 8 after run command
sudo gsettings set org.gnome.Vino require-encryption false

but in Redhat 7 when i run above command i got warning message:

(process:60483): dconf-WARNING **: 13:49:27.940: failed to commit changes to dconf: Cannot autolaunch D-Bus without X11 $DISPLAY

any help … !!

Hi All,
is resolved.
install dconf-editor and change this go to > /org/gnome/desktop/remote-access/

and switch Off to value: require-encryption

thank you and Regards.
