Hello,
I cannot open a graphic tool on my Debian TDE, with a terminal and SSH, from a remote server, I receive this message : # xeyes "X11 connection rejected because of wrong authentication. Error: Can't open display: localhost:10.0"
Everything is allright with SSH, sshd_config, ssh_config...
I readed many advices from internet sites, nothing to do, it does'nt work with this eternal message above.
Thanks for a lead.

$ grep -i X11Forwarding /etc/ssh/sshd_config X11Forwarding yes # X11Forwarding no
then when you login ( ssh -X ) export DISPLAY=:10
or
export DISPLAY=localhost:10
if still an issue check what is loclahost in /etc/hosts

$ grep -i X11Forwarding /etc/ssh/sshd_config X11Forwarding yes :
OK.
then when you login ( ssh -X ) export DISPLAY=:10 or export DISPLAY=localhost:10
It's what I did.
if still an issue check what is loclahost in /etc/hosts :
cat /etc/hosts (on the remote server) : 127.0.0.1 localhost localhost.localdomain
And always the message : "X11 connection rejected because of wrong authentication. Error: Can't open display: localhost:10.0"

the display is localhost:10.0
unless you connect second time (see X11DisplayOffset)
And you access with :10 (no .0 at the end) short: ~$ export DISPLAY=:10 ~$ xeyes
worked always and worked this time as well Actually I do not even have to export DISPLAY - it is set automatically by SSH
PS: If you change SSH config, you have to restart sshd and connect again (ssh -X)

export DISPLAY=:10 you need some xstuff (xauth for example you need on the client side) what you also could do is use -v option or -vv or -vvv
Must be written on the SSH server ? : export DISPLAY=:10 root@association-starinux:~# echo $DISPLAY :10 # xclock Error: Can't open display: :10 The DISPLAY is never accepted, whatever the number.

are you logging in as root or normal user and doing su/sudo? later would explain all of your troubles it is complicated to login as normal user and run X app as root.

Yes, true, difficult Xorg graphic relation between user and root.
From the client SSH, as user, I type : $ ssh -X -p <port> root@<server-IP> and I'm connected.
If I type : $ ssh -X -p <port> normal-user@<server-IP> I'm connected with this message : "/etc/ssh/sshrc : line 13 : /etc/ssh/logsshsftp.sh : Permission not granted"
$ xclock "X11 connection rejected because of wrong authentication. Error: Can't open display: localhost:2.0" sniff :-(

All of this is crap - what is sshrc and logsshsftp.sh why localhost:2.0?
try creating a fresh normal user and try with that user. You have to review this configuration.

/etc/ssh/sshrc is a script that is executed upon ssh login apparently ajh-valmer has some crap in here that breaks normal ssh -X functionality

sounds like Ubuntu crap - for the rest it is not helpful to explain the obvious, but I can think that it is not obvious for all.
if it's Ubuntu I don't know

"/etc/ssh/sshrc" and "/etc/ssh/logsshsftp.sh" are not the problem, they only add the connections, date, time with SSH : 19-03-2021--10h38m <IP-server> The problem is elsewhere.
The important questions are : - Do I have to install a X server on the computer-server SSH ? - Why the DISPLAY regardless of the number is never accepted ?
Thanks,

you install what is required to operate the application - dependencies should tell you what.

Because we concluded that your setup is broken and you have to repair it.

Tis is the version where X11 forwarding works or where it does not work?

One or two or three -v "verbose" doesn't give informations about X11 forwarding.

Please attach a logfile that you get from a session where X11 forwarding does not work and one where it does work. You'll need to include the output from the (not) working X11 client, too. e.g.:
ssh -v -X user@server xmessage xxx
