Tortoisebot/Raspberry credentials

[Ashish080213]

@KarthiAru try login id: tortoisebot password: raspberry

[KarthiAru]

I updated the sshd_config file to enable public-key authentication instead of password authentication. I also installed tightvnc on raspberry to connect from the laptop.

@KarthiAru Did you try RealVNC Viewer?

@KarthiAru Did you try RealVNC Viewer?

Yes, I used the realvnc client from the laptop

[Ashish080213]

@KarthiAru Did you try that without using any HDMI cable? if yes then are you able to use realvnc without any error? I have an issue that its showing "Cannot currently show the display".
But if I connect the raspi to the monitor using HDMI cable and if I connect realvnc using my laptop its working fine.

Yes, I'm able to view the raspi desktop without issues. I didn't use any HDMI cables.

These are the steps I followed to set it up.

0. Update VNC server settings

tortoisebot@ubuntu:~/.vnc$ pwd
/home/tortoisebot/.vnc
tortoisebot@ubuntu:~/.vnc$ sudo nano xstartup

#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
startxfce4 &

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &

1. Start VNC server

tortoisebot@ubuntu:~$ tightvncserver
New 'X' desktop is ubuntu:2
Starting applications specified in /home/tortoisebot/.vnc/xstartup
Log file is /home/tortoisebot/.vnc/ubuntu:2.log

2. SSH connection with port forwarding in a new terminal
   ssh -L 5902:localhost:5902 -vNC [email protected]

If New 'X' desktop is ubuntu:1, then port is 5901
If New 'X' desktop is ubuntu:2, then port is 5902 and so on

3. Open the VNC client and connect to server using
   localhost:5902
