This was fantastic. Just as a heads up, you can use:

xauth list | while read x ; do sudo xauth add $x ; done

Which will automate the process of adding the information into xauth. I put it in my .bashrc so when I log in it just simply works. You might want to add that to the post so other people might benefit it as well.

pilotHans, check the permissions on the .Xauthority file. The oracle user needs to own it and have read/write on it (chmod 0600 ~oracle/.Xauthority)

I had also been under the same circumstances. But now, I am locked and loaded & I am pretty hopeful I will get rid of this error and can easily use applications that require X Windows frontend. Thanks a lot for sharing this wonderful post.

[...] Here is a good tutorial show you how to Fix Xlib: PuTTY X11 proxy: wrong authentication protocol attempted: On recent OpenSSH Server releases, you can simply enable “ForwardX11Trusted yes” in the /etc/ssh/sshd_config file and restart the OpenSSH server. If you’re not using a recent OpenSSH Server release or if you can’t for security or political reasons, what could you do? Give up? It’s simpler than you think. [...]

Thanks for the article. Its the exact situation I’m in. (windows laptop but have to run oracle install xwindows gui from solaris box – I don’t have login to ‘oracle’ user but sudo privs.)

I got putty’s ssh (with x11 forwarding) to finally allow my login to run xclock, but couldn’t run it after sudo to the oracle user. When I tried to add the cookie as described in the article, I got:

xauth: timeout in locking authority file $HOME/.Xauthority

All I had to do was change my home directory to ‘read/writable’ (ie. chmod a+rw $HOME/.) and it worked. Thanks a bunch.

XWindows is not really that complicated – but since its a networked based GUI system, its getting the networking to work that can be a pain.

Great article. Wish I would have seen this before wasting 10 hours troubleshooting and testing.

Since you brought up politics, my question is — Should I let the security people who locked down all of our servers without warning or workaround know about your great solution? When they treated my like an annoying thorn for asking them to help? Muhahaha

You could write a script that writes the DISPLAY and xauth info to a file prior to changing users. As long as the user you changed to as read access to that file, you should be able to.

Thank you for the article…Each time when I logout and login I see this error.
Is there any one time fix that can be incorporated. I used Xming.

Thanks for article. I was not aware of such utility on linux as well.
Thanks much for that.
