The iceauth program is used to edit and display the authorization information used in connecting with ICE (the X11 Inter-Client Exchange protocol). It operates very much like the xauth program for X11 connection authentication records. All questions regarding this software should be directed at the Xorg mailing list: https://lists.x.org/mailman/listinfo/xorg The primary development code repository can be found at: https://gitlab.freedesktop.org/xorg/app/iceauth Please submit bug reports and requests to merge patches there.
