Hi Folks (and sorry for anu cross postings)
Following a mysterious mishap when something on a website crashed my Firefox. the machine I was using is now not accepting X connections from either of my other two machines.
I can't get to the bottom of it, and would welcome any suggestions.
The basic symptom is:
From machine A (compo, the screwed-up one) I log in to
either of my other two (say brandy) from an xterm in Gnome.
On the remote login, I then issue the command 'xterm' and hope to see an xterm open on compo (as normally happens). Instead, I get the following message from the remote (brandy):
ted@brandy:~ > xterm Xlib: connection to "compo.fort.knox.uk:0.0" refused by server Xlib: No protocol specified xterm Xt error: Can't open display: compo.fort.knox.uk:0.0
(Exactly the same message from the other remote machine)
This situation arose immediately following the Firefox crash (Firefox running on compo, machine A). Connections which were already open continued to work. By now, though, I've tried (amongst other things) rebooting. and now there's no joy on any front. It makes no difference whether I'm root or an ordinary user eiher locally or remotely, nor whether I 'startx' as root or ordinary user/
(BTW, I can give some details of the remote web site which crashed Firefox if people think it may help, since I suspect it of monkey business. but will hold fire for the moment since it may not be relevant).
With thanks (and I'm pretty pressed to get this working again!) Ted.

Well, Hi again!
For some equally mysterious reason, having left compo alone for a while, I find it is now accepting X connections normally -- it just seems to have managed to clear itself!
So panic over, but it's still mysterious! (up to then, it had been refusing for over an hour, through restarts of X, through reboots, etc.)
Best wishes to all, Ted.

Ted
If this happens again its because you dont have permissions on the compo to display. You need to use the "xhost" command. I use "xhost +" as I normally use captive systems BUT this is a big security risk, so man the xhost pages.
HTH
