Xnest authorization change?
Last modified: 2007-04-18 12:33:43 EDT
Just upgraded to 7.1 + errata, suddenly Xnest doesn't seem to work, it rejects all client connections. It will print something like: AUDIT: Mon Jun 18 01:59:04 2001: 25726 Xnest: client 1 rejected from local host And clients can't connect. Maybe this is just me being dumb instead of a bug, but it's at least a docs bug, I have no clue how to enable connections to the Xnest ;-) I've never had trouble in the past.
Owen points out that I can disable access controls with "Xnest -ac" or somehow get xauthority to work with "-auth". Neither is in the Xnest man page, and Xnest is useless unless you pass one of these options as far as I can tell. So I think it should exit with the error message "must pass -auth or -ac" if you don't pass one. Clearly this is material for an upstream change not a RH patch...
Which 4.1.0 release is it causing the problem?
I seem to have 4.0.3-5. Possibly the rationale for this behavior is that you could use Xnest to test how authentication works...
I've tried various combinations of Xnest tonight having never used it before, and it is c001. ;o) I tried 3 different 4.0.3 releases including -5, -16, and -21. They all work, so I think it is a local authentication issue. Here is what I did: 1) Running stock 7.1 KDE, I open up a konsole 2) Xnest :2 3) xmorph -d :2 it works. I tried other apps too, and it works. I seem to recall someone else having a similar problem but not with Xnest. Good chance this is similar. I think it is just config issue though I believe. What are you using to run it? GNOME/KDE? What term program?
Interesting. So I assume the issue is gone in newer Xnest or something. I'm using gnome-terminal, just tried xterm and it's the same. I can't imagine how that would make any difference though.
I can't either, but I just wanted to be able to try and dupe what you're using. Are you using only stock 7.1+updates? Or + GNOME 1.4 also?
I had a mostly 7.0 system, ran the 7.1 installer, then ran up2date to get all errata.
I don't have any problem using Xnest in stock 7.1 with 4.0.3-5, or with the above mentioned releases, nor with 7.1 + XFree86-4.1.0-0.8.6 nor with our latest internal CD snapshot of the next release. I don't know what the problem you're having but I have no trouble running it at all. I do not have any special customized X configuration, just stock, no .xinitrc, .anything that might mess with this. Check your configs for anything that might mess with the authentication mechanisms. I am assuming you are running Xnest locally on the same box as the Xserver resides. Is this correct?
I can't even reproduce this now; I still have the same X version. Random transient bogon.
