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

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,
Paul

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.

And before we move on I'd like to point out that Dartmouth College was the place where the programming language BASIC was developed back in 1964. Two guys, J. Kemeny and T.

BASIC also helped a couple of other guys, Paul Allen and Bill Gates, gather up all the loose money in the world by developing a version of BASIC that would run on the Intel 8080. I'm sure most of us have dones somet...

Is there a way to view Stored Procedure, Trigger andFunction Usage in SQL Server?
I am maintaining an application where most of the business rules are in Triggers, Stored Procedures and User Defined Functions. When a bug arises, it can get very tedious to debug. Today for example, I wanted to modify a function that was being called by a trigger. The problem is that I don't want to change the function, for fear that it is being called by one of the other SP's or triggers in the database (there are hundreds of them) Essentially, I need a tool that allows me to view where functions and sp's are being referenced from. At the very least, I'd like to perform ...

x += ... is not the same than x = x + ... if x is mutable
Hi, I thought that x +=3D ... was the same than x =3D x + ..., but today I have= realized it is not true when operating with mutable objects. In Python 3.3 or 2.7 IDLE (Windows) compare: >>> a =3D [3] >>> b =3D a >>> a =3D a + [1] >>> b [3] and >>> a =3D [3] >>> b =3D a >>> a +=3D [1] >>> b [3, 1] Is this behaviour explained in the Python documentation?=20 Thanking you in advance, Bartolom=E9 Sintes bartolome.sintes@gmail.com writes: > Hi, > > I thought that x += ... was t...

A new approach to specifying typelists?
Hi, I've been using Loki-style typelists extensivley in my code for a while now, and have found them extremely useful, although somewhat annoying to specify due to all the close angle brackets required. Recently, though, I started using this syntax: //////////////////////////////////////////////////////////////////////////// struct TypelistEnd {}; template<class _head, class _tail = TypelistEnd> struct Typelist { typedef _head Head; typedef _tail Tail; template<class t> struct Add { typedef Typelist<t, Typelist<_head, _tail> > Type; }; }; ////...

Long Connection Times with Outlook
I have a Slackware mail server running sendmail-8.14.3 that forwards all non local mail to another off site mail server for delivery. The local clients and my server are on a 1000BASET network and my mail server connects to the forwarding off site mail server via a permanently up connection. I am having a problem with Outlook clients that are sending many large duplicate emails with attachments ( 9MB total) to non local email addresses when the user is only trying to send one email. What I think is happening is that Outlook connects to my mail server and my mail server then conn...

Cannot Ping or Telnet Server After Restore
Following a retsore of a complete image backup from one 7.1-2 server (Alpha 4000) onto another (Alpha DS20), and the change of the UCX Core Interface parameters, the server does not appear to on the network after reboot. The The 4000 is still on the network so we cannot keep the same IP address. The memory of the DS20 is 512MB compared to 2GB for the 4000. Watching the startup messages on the console shows that the startup of UCX commences, but when it gets to the stage when it starts the TELNET service the startup appears to stop: "Message from user INTERnet on BRXXXX INTERnet ACP Activ...

Unable to ftp to server in DMZ PIX 515e
Good Afternoon, I have built an apache webserver running on FreeBSD and placed it in the DMZ of our Cisco 515e. I am trying to setup ftp from internal LAN to the server. However, everytime I try to ftp to the server,which resides in our dmz, from the internal network the connection times out. I can SSH to the server without any issues. I can also access the website that the webserver is running via Internet explorer. I can ftp to the server from other servers that are in the dmz. If i put the server on the internal network and re-ip the server it also works fine which tells me it is something...

X-plane on a G4
