LMDE 5, connexion problem with VNC server

Mitchell · Post by **Mitchell** » Mon Apr 03, 2023 4:30 pm

Hello,

After upgrade from LMDE 4 to LMDE 5 (fresh install in fact) I had to change the VNC server setup from vnc4server (oldstable,now 4.1.1+X4.3.0+t-1 amd64) who works on LMDE 4, to tigervnc (stable,now 1.11.0+dfsg-2+deb11u1 amd64) because the first one is no longer available on LMDE 5.

It seems that all paquets are installed

Code: Select all

sudo apt list --installed | grep vnc
tigervnc-common/stable,now 1.11.0+dfsg-2+deb11u1 amd64  [installé, automatique]
tigervnc-scraping-server/stable,now 1.11.0+dfsg-2+deb11u1 amd64  [installé]
tigervnc-standalone-server/stable,now 1.11.0+dfsg-2+deb11u1 amd64  [installé]

And the server is running and listening on port 5900 for the :0 display

Code: Select all

x0vncserver -list
TigerVNC server sessions:

X DISPLAY #     RFB PORT #      PROCESS ID      SERVER
:0              5900            848             X0tigervnc

Code: Select all

ps -ef | grep vnc

There's no FW rules, I'm working on a test machine without security just to figure how to make it works. And other connexion requests are working, like SSH and SFTP.

Here's the machine détails

But when I try to connect to this machine via VNC I had a VNC Connection Refused code #10061.

I not an expert, but also not a full newbie, plus I followed a couple of How To for Debian 11 to try some things, but nothing's working.
So any help will be appreciate, I can do/try everything on the machine since it's just for test up to I figure how to make it works.
