Title: Re: Need Help Beating X11 Into Submission
Hi Ray,
I’m not an expert, but I had similar problems. The X11 update that came with Tiger wants you to only use ssh –Y to connect. But I need to telnet to make our load sharing software work. So... To make telnet, or rlogin work, somebody sent me the following email and it fixed the problem:
The parameters of the X Window server have been chosen by Apple to allow only ssh -Y connexions and remote display. Generally "xhost +hostname" is not secure. In those cases where the network is secure (or if there is no other solution), it is possible to activate the traditional method.
All you have to do is to type the following command, in a X11 xterm on your Mac :
defaults write com.apple.x11 nolisten_tcp -boolean false
You can check the value of the nolisten_tcp parameter with the command
defaults read com.apple.x11
You will see the value "nolisten_tcp" = 0 (the value was "1" before)
Note that if you change your X11 preferences via the menu X11 -> Preferences... the parameter nolisten_tcp will be reset to "1" (true); you will have to change it again.
There is another method which can be used : MIT-Magic-Cookie. You don't use xhost +, just setenv DISPLAY on the remote host. Both the X11 server and the X11 client must run xauth.
Once again xauth must be enabled on the Mac :
defaults write com.apple.x11 no_auth -boolean false
You must exchange keys between the Mac and the remote unix station. It is heavier to use, but it is secure.
I hope your problem will be solved (tell me). I can now use rlogin, rsh on remote Sun Stations and send the display to my Mac with setenv DISPLAY myhost:0.

I have a new Mac mini I'm trying to use purely as an X-server, but I am finding it extremely frustrating. On first unpacking the system, it booted up and configured itself flawlessly. I installed X11, and started it, typed "xhost +" and was then able to start X applications (in particular KDE Desktop) from our Linux farm with no problems. After a while, I exited X11, and repeated the same steps, but with no luck. X11 starts and works just fine, the xterm comes up and works just fine. "xhost +" indicates it will accept connections from any client, but the Linux farm refuses to acknowledge there is an X-server present. I have since configured X11 as a Startup item, so it comes up on boot-up. If I keep rebooting over and over, eventually, everything will work again, but as soon as I shutdown X11, it goes back to not working for some random long, usually long, period of time. In all cases, whether the Linux farm acknowledges the presence of the X-server or not, I can always ssh into the farm and launch X-applications that display on the Mac using X-11 forwarding.
Any ideas what's going on? I'm about at the end of my rope with this thing.
Thanks!
Regards,
Ray L.
