X11 Forwarding

In remote host (server, X11 client) enough(?):

yum install xauth

in /etc/ssh/sshd_config:

X11Forwarding yes

and .Xauthority file existing in user's home

But if there are problems with autogenerating .Xauthority file then set these parameters:

X11DisplayOffset 10

X11UseLocalhost no

maybe need:

yum install xorg-x11-apps or yum install xclock (when installing ora_db via ssh x11 does not work for 'oracle' user until installing xclock)

In mac OS X (client, X11 server) there is:

/etc/ssh/sshd_config:

# XAuthLocation added by XQuartz (http://xquartz.macosforge.org)
XAuthLocation /opt/X11/bin/xauth

/etc/ssh/ssh_config:

# XAuthLocation added by XQuartz (http://www.xquartz.org)
Host *
    XAuthLocation /opt/X11/bin/xauth

echo $DISPLAY:

/private/tmp/com.apple.launchd.uWIthx5xdu/org.macosforge.xquartz:0

echo $DISPLAY in Linux Client:

:0

XQuartz security settings:

(may be need to toggle off selinux and firewall for .Xauthority generation; also check $DISPLAY environment variable; uncomment X11Forwarding in ssh_config; and something else operations of this mind...)

(somewhere on forums takes place this solution:

in /etc/ssh/ssh_config add/uncomment:

XAuthLocation /usr/bin/xauth
ForwardX11 yes
ForwardX11Trusted yes

)
