[Xquartz-dev] Remote X11 Connections Blocked on Leopard vs. Tiger

[Grant Erickson]

Arguably belatedly, I made the transition from Tiger to Leopard on my
various machines yesterday.

In general, the transition seemed to go smoothly; however, some bumps have
been encountered with X11 (Xquartz 2.1.5 - (xorg-server 1.3.0-apple22)
(2.1.5)).

A partial work-around to start-up issues resolved (
http://lists.macosforge.org/pipermail/xquartz-dev/2009-March/002204.html), I
am now running into remote connectivity issues.

I am not using SSH X11 forwarding, DISPLAY seems to be correct on both sides
of the connection, all four combinations of X11.app security settings seem
to have no impact and neither xhost nor xhost + seem to work:

    aesop% echo $DISPLAY
    /tmp/launch-3n3Zy2/:0

    % ping -c 2 fenster.local
    PING fenster.local (192.168.1.14): 56 data bytes
    64 bytes from 192.168.1.14: icmp_seq=0 ttl=128 time=0.796 ms
    64 bytes from 192.168.1.14: icmp_seq=1 ttl=128 time=0.290 ms

    aesop% xhost +
    access control disabled, clients can connect from any host

    aesop% slogin fenster.local
    fenster.local's password:
    Last login: Wed Mar 18 19:32:47 2009 from 192.168.1.2

    fenster% echo $DISPLAY
    192.168.1.2:0.0

    fenster% ping aesop.local 56 2
    PING aesop.local. (192.168.1.2): 56 data bytes

    64 bytes from 192.168.1.2: icmp_seq=1 ttl=64 time=0 ms

    fenster% xemacs &
    X server not responding
    : "192.168.1.2:0.0"

    aesop% grep X11 /etc/ssh* ~/.ssh/*
    /etc/ssh_config:#   ForwardX11 no
    /etc/ssh_config.system_default:#   ForwardX11 no
    /etc/sshd_config:#X11Forwarding no
    /etc/sshd_config:#X11DisplayOffset 10
    /etc/sshd_config:#X11UseLocalhost yes
    /etc/sshd_config:#    X11Forwarding no
    /etc/sshd_config.system_default:#X11Forwarding no
    /etc/sshd_config.system_default:#X11DisplayOffset 10
    /etc/sshd_config.system_default:#X11UseLocalhost yes
    /etc/sshd_config.system_default:#    X11Forwarding no

    fenster% grep X11 /etc/ssh* ~/.ssh/*
    /etc/ssh_config:#   ForwardX11 no
    /etc/sshd_config:#X11Forwarding no
    /etc/sshd_config:#X11DisplayOffset 10
    /etc/sshd_config:#X11UseLocalhost yes
    /etc/sshd_config:#    X11Forwarding no

This all worked OK under Tiger. Any thoughts on what I might be missing or
miss-setting here?

Thanks,

Grant
