gdm rejects any X11 TCP requests despite 'DisallowTCP=false' in custom.conf Description of problem: gdm Window Manager ignores the 'xhost +' cmd and rejects any incoming X11/TCP requets despite the 'DisallowTCP=false' added to the custom.conf file. Version-Release number of selected component (if applicable): Fedora 8 Steps to reproduce : prerequisite : ---> custom.conf must override unmodified 'default.conf' file, allowing TCP access for X11 requests ( see file hereby attached ) 1. on the Fedora 8 X/gdm server, issue the 'xhost +' command in a terminal window [philec@philec-linux ~]$ xhost + access control disabled, clients can connect from any host 2. rlogin or telnet to any other Linux, Solaris, HP-UX, AIX 3. initialize and export the $DISPLAY variable [philec@philec-pro ~]$ export DISPLAY=philec-linux:0.0 4. launch the 'xterm' command on the remote system [philec@philec-pro ~]$ xterm xterm Xt error: Can't open display: philec-linux:0.0 Expected results: xterm window starts on the 'local' X/gdm server Additional info: When sniffing the X11/TCP transaction, the Fedora 8 clearly returns a 'host administratively prohibited' ICMP packet ( see trace attached )
Created attachment 302234 [details] libpcap trace of failing X11/TCP transaction
Created attachment 302235 [details] gdm custom.conf file under /etc/gdm main default.conf file in /usr/share/gdm remains unmodifed
