Xming: wrong authentication protocol

Ever had the “wrong authentication protocol” error when using Xming and xhost+ still did not work?

When you are on a private network, you can try using the “-ac” option when starting Xming. Use this only on private trusted networks, because it gives access to everyone.

For mote information on Access Control in Xming and X-Forwarding with PuTTY and SSH, check the Xming troubleshoot guide.

Happy consulting!
