X server refuses to communicate with new connections

I've installed 2.9 on a SunBlade 100.   I'm running twm and
seem to have hit a snag.  I keep getting this error message:

   : xhost +
   Xlib: connection to ":0.0" refused by server
   Xlib: Client is not authorized to connect to Server
   xhost:  unable to open display ":0.0"

after a while.  I can't open new windows after this.  It doesn't
seem to be related to the number of windows.  It seems to be  
more time related.

Sometimes this occurs within a few minutes but, it might take a 
day?  I'm hoping someone knows of a patch, or a setting, that 
will cure this problem.

I start X up with:

  xinit -bpp 32 -clients 1024

TIA,
Paul

Maybe the file
..Xauthority
in the user's home directory is missing or corrupted?

Corruption can happen due to diskspace problem.

The same thing happens when you have switched to a new user.

My local disk is only 15% utilized (the max in any filesystem).

The .Xauthority file had no entries.  I added one.  Just have to
wait now, it it doesn't recur in a week or so I'll consider it fixed.
I didn't consider such things since it would always work for a while.
A bad .Xauthority file should have started out bad from the get go
.... no??  I'm wondering if exmh is doing something bad.  It likes
to remove entries shown by xhost??

Thanks,
Paul

Do you have a cron job removing files in /tmp?  If so, make sure it
doesn't touch anything in /tmp/.X11-* or you will see exactly this
problem.

Doesn't look like there is anything cleaning up like that.

Now I'm getting this:

   : xhost
   Xlib: connection to ":0.0" refused by server
   Xlib: Invalid MIT-MAGIC-COOKIE-1 key
   xhost:  unable to open display ":0.0"

Fixing .Xauthority file changes the error message alittle bit.

I'm baffled,

Paul, I suspect that this will not help in the slightest, but why run 
Tom's (Antique) Window Manager? Do you have similar troubles if you run 
dtwm or the Bloated Gnome?

You are right, it hasn't helped at all.

> but why run Tom's (Antique) Window Manager? 

I like twm and run it on all my *ix boxes.  It's simple, lightweight 
and I don't have to keep translating my .twmrc file into other formats 
so I can have the same, or similar environments, as I hop between OSes
- i.e. habit.  I don't like the appearance of CDE/dtwm and it always 
seems quite sluggish to me.  That's probably a side effect of these
low end desktops, rather than CDE/dtwm.

> Do you have similar troubles if you run dtwm or the Bloated Gnome?

No idea.  I disabled both immediately on this 2.9 box.  I did not
have these problems on 2.7.  If I can't get a resolution to this 
soon I'm going to install Linux or NetBSD on this thing and move along.
I've never seen this problem before on any platform.

I do appreciate the suggestions so far, but they don't seem to be
the problem.

Still baffled,
Paul

When this happens, do the files /tmp/.X11-unix/X0 and /tmp/.X11-pipe/X0
still exist and are they world writable?  Are there any errors in 
/var/dt/Xerrors ?

No, but I'm running twm not dtwm so would twm write to that file?

I'm trapping the twm stderr & stdout, I see a lot of this:

BgRegister X server insecure (must use xauth-style authorization); command ignored
BgRegister X server insecure (must use xauth-style authorization); command ignored
BgRegister X server insecure (must use xauth-style authorization); command ignored
BgRegister X server insecure (must use xauth-style authorization); command ignored
BgRegister X server insecure (must use xauth-style authorization); command ignored
exmh-bg cannot rendez-vous with UI - exiting.
  Usually this is because Tk send is not working.
  Check the notes under Frequently Asked Questions #4a and #4b.
  You can find this under the Help menu.

this is exmh.  I saw lots of this on 2.7 as well.  I'm connected to a
mail machine over a ppp connection tunneled through ssh.  Exmh is 
executing on the other end and displaying on the 2.9 machine (just like
it did on the 2.7 machine).

Still baffled,

Ok, for those who are interested.  It appears that in Sol 2.9 once the
local display is removed from the xhost/access list it cannot be added 
back and you cannot change the xhost list at all (probably not saying 
that quite right).

I noticed that my local copy of exmh (not the one displaying from a 
remote system) likes to go through and remove entries.  This is a 
"security feature".  This feature has been doing the same thing on
2.7 as well as NetBSD 1.5, and forward, BUT 2.9 apparently reacts
a little differently and locks out changes to the access list once
the LOCAL host is removed ... which exmh does eventually, when in the
insecure mode.

I am now starting xdm and this changes the behavior.  Exmh doesn't
do the removals anymore since it thinks the system is now secure
(apparently??).  And the problem doesn't seem to occur anymore.

Unfortunately, a new oddity has appeared.  Now, post will not post 
mail for exmh, declaring "Polite people say HELO first".  I have no 
idea how, or why, these two things are coupled but, they apparently
are?  2.9 is giving me a headache like I haven't had in quite some 
time.

In corba, is there any way to dynamically throttle the number of client connections a server has? How can one tell the server to refuse, or stop accepting new client connections?

Java, "Connection refused: connect"
I've been happily playing away with my client/server program for most of this weekend. I decided earlier today to take it to the next step and try running it on two machines. ....Boy did that not go over well. The funny thing is, I did everything I could possibly thing of to make the program real-network-ready. But then I got this: -=- java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) -=- Not descriptive, but okay, I did a google for this, and got hundreds of: "That error means you don't have a server run...

Connecting To New Server
So I just came out of the depths of docs.sun.com without an answer to this question (trying to find a needle in a haystack). Maybe someone can toss a bone my way. I have a handful of Linux servers which of course I can administer remotely. However, upon first taking them out of the box, I connect a monitor, start them up and assign an ip address. Off I go. I'm about to grab my first Sun server which does not have video output. After connecting it to my LAN and starting it up, how is it that I "get to" that server the first time? How do I address it? I can understand in larg...

Do you need an X server on an headless server to run X apps over ssh (X forwarding) ?
Is there a way to open an ssh connection to an headless sun server, and have an x application from the sun server, display on my PC ? I would tend to think that it is possible, but for now, it is not working. I have cygwin X server on my PC. I use putty or secureCRT to connect to my headless server and I checked the forward X option. The X forwardinf is also ON in the ssh_config file. I assume that the DISPLAY variable in the ssh-server should be: mp_pc_ip:0 ? It does not work. Right now, the DISPLAY variable is set to localhost:10 (That is, it assumes the X server is running on the solar...

Cannot connect to X server
Lately (and periodically) I've run into the problem where I can't run X progs as root. I have KDE on Debian unstable. For instance, I can't run Kedit as root, getting this error message: kedit: cannot connect to X server :0.0 xhost +localhost doesn't fix the problem. If I do su -m it does fix it. I would like to be able to run X apps as root, with root's environment, automatically -- LinW (Linux is not Windows) On 4/28/2004 10:59 AM, I believe that Jim Bowering wrote: > Lately (and periodically) I've run into the problem where I can't run X pro...

Looking for a list of new server console commands for D6.x or D6.5.x
Does anyone know where I can find a list of just the new server commands? I'm just looking for commands that are new with D6.x or D6.5.x I know some are in the Admin Help, but I was looking for a list of just the new ones's only. Thanks, Tim Brown I don't know of a list, but I can tell you one new one to be careful of. TELL ROUTER UPDATE CONFIG is a nice command to tell the Router to reload the configuration immediately. What you don't want to do is issue this on an R5 server. If you do, you will enable shared mail. Tim Mohrl�nt - tmohrlant@NO_JUNK_MAIL_c...

Connecting to a Server on a Server
I have a chat client that needs to connect to a chat server in order to function. This is for research use so I have access to an academic server named Updraft. For this research, Updraft acts as a central point where all data is accumulated. It would be real nice if I could have all the chat client connect to the chat server that resides on Updraft. I problem I see here is that Updraft uses SSH and the chat clients use IO::Socket::INET. That means that first a user would have to login to Updraft using SSH then the client program creates a socket using IO::Socket::INET. That seems a bit strang...

server to server communication
I am working on a web application using Tcl and would like opinions on a couple of matters. I want to know my options for communicating from one server to another when using a shared hosting account. I cannot find information in clt nor web in general. Most everything on wiki.tcl.tk is geared towards those who have their own web server. Currently, app users log in to my tcl app on server A with password and my system does db look up and writes a cookie if password matches. The cookie is checked on all subsequent script accesses. So far all is well. I now want to the user to access my se...

rlogin + NAT = Connection from x.x.x.x on illegal port
Hi NG, when I try to use rlogin with NAT (behind a Loadbalancer). I did not get a connection and in /var/log messages I get Connection from x.x.x.x on illegal port. Can I reconfigure the rlogin to allow rlogin from other ports or is there another problem?
