The problem may be related to Ubuntu (experienced on 10.4) apparently executing the commands
xhost +si:localuser:`id -un` xhost +si:localuser:root xhost +si:localuser:gdm or does something equivalent when you log in. Just type "xhost" to see the list of non-xauth authorizations currently enabled for your X11 server. The first of the above lines is in /etc/X11/Xsession.d/60x11-common_localhost The exmh background daemon considers the presence of any of these to be bad and therefore refuses to work. Executing the above three lines with + changed to - is a workaround, but ultimately exmh-bg (or a library it uses) probably needs patching to tolerate this practice. See also "man xhost". -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. https://bugs.launchpad.net/bugs/371181 Title: xauth authentication not working -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
