We rebooted the server an got the following error:

RHEL xhost unable to open display ""
Can't login or do anything at the monitor or kb. How ever I can ssh to the server, not sure where to start looking. I have two servers that are the same and checked the xorg.conf on both servers and they looked the same.
I have configured an instance in AWS EC2. I am trying to set the display back so I can run x apps. I login using ssh -xy -i...
export DISPLAY=XXX.XXX.X.XXX:0.0
echo $DISPLAY to verify
xhost +
xhost: unable to open display "XXX.XXX.X.XXX:0.0"
I have commented out nolisten tcp as suggested HERE I have modified /etc/gdm/custom.conf as suggested HERE Actually, the last suggested modifying /etc/gdm/gdm.conf, but that file didn't exist, so I added the line: DisallowTCP=false to /etc/gdm/custom.conf I rebooted, and still I get: xhost: unable to open display "XXX.XXX.X.XXX:0.0"
Thats my problem at the moment, i cant open YAST without using the command "xhost +" before on bash.

I'm experimenting with old linux Distributions again, and while trying tostart an x server, I get the following error message:X: unable to open display ''That makes me think that the config file is incomplete, but I would have no idea how to make it. If there is an auto configuration utility that I do not know about for X, it would be great to hear about. Here are some other specifications that might help:*Host: VMWare Workstation on Windows XP Home*Distribution: Debian 2.2 (potato) (Yes, I know it's old.)*Connection: Local. I've heard of people having difficulties like this on remote connections, but I am on the physical computer

In oreder to run an application software on RHEL 3 ES server, I created a link forcefully using following command from root id:
# cd /lib64/tls/
# ln -sf libc-2.3.4.so libc.so.6
before that I copied file libc-2.3.4.so from a workstation with OS RHEL 4 WS so that a link can be created.
Now I am unable to run any command except cd & pwd and it gives error messaage as given below:
ls:relocation error:/lib64/tls/libc.so.6:symbol _rtld_global_ro,version GLIBC_PRIVATE not defined in file ld-linux-x86-64.so.2with link time reference.
Before running this command libc.so.6 was pointing to libc-2.3.so file in path /lib64/libc-2.3.2.so.
I am now unable even to open a new window on the server.Please send me some solution as early as possible because this server is running production data and many users are runnig application on this server.
Ever since upgrading to Fedora 14, my system has been almost unusable. I can only have a few windows of anything open before I start getting messages about:
Maximum number of clients reachedMaximum number of clients reachedMaximum number of clients reachedMaximum number of clients reachedxwininfo: unable to open display ':0.0'
I am unable to open any new windows then and lots of programs crash.

i recently moved from Ubuntu to Debian(squeeze).. i am very pleased with squeeze except for this bug..I have this python script i wrote to change my wallpaper (through Gconf), the script would be called by cron from time to time.The problem i am facing in Debian is that this script stopped working.I am exporting the $DISPLAY=:0 in Cron, (this is how it worked in Ubuntu)..the cron job i used is below:
-----------
* * * * * export DISPLAY=:0 && /path/to/my/script.py
--------
so the above was not running...I redirected the output and this is what i got as error:
-------------
Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See http://projects.gnome.org/gconf/ for information.

is possible to edited the default RHEL CD to have it automatically install RHEL based off of a kickstart file that I will store locally on the CD. My plan would be to put a cd in a server and have the OS automatically being installed.

View 1 Replies View RelatedI have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.

View 2 Replies View RelatedI have a database server running RHEL 5.1 32 bit that suffered some catastrophic failures about 6 months ago. We were able to patch it back together and keep it running, but now the manufacturing site it supports is going to shut down for two weeks and I would like to replace it permenantly. Does anyone have any guidance for that sort of thing? I'd like to have the new server up and running before hand, basically changing the hostname/ip and restoring the databases only on conversion day. I've done this in the past with HP UX - Red Hat conversions, but this is my first red hat to red hat move. Any advice or shortcuts?I forgot to add the other wrinkle. The new server will be running 64bit linux.

We have a digital signage appliance built on SUSE 11.3 with a LAMP server that uses the flashplayer application to play a .swf file from localhost. It is a AOpen GP7A mini pc that has the nVidia drivers loaded. We have lots of customers that have been running the exact same system for over 6 months (we image the drive for each sale).
For some reason, my last customer is seeing the following problem shown below, and this linux configuration is way over my head. Everything else is working (local LAMP server is working, communicating with our production servers to get information works, etc). I have verified that it is screen 0 that is running (at least it shows with Ctrl-Alt-F7). I thought that it may have occurred because of updating the software with zypper up. I had the customer rebuild from the image being careful not to upgrade the software. The result was the same. The pc is a newer version compared to my bench pc, but there are multiple other customers running that same version just fine. So I am not sure if it is
The command is issued by a php script that is run in a root cron job. As I said, it works great on all other customer pc's including my bench system. I also tried to execute the command on a ssh terminal as the root user with the same result. I also upgraded my bench pc and it still worked properly.
The command being executed is sudo env DISPLAY=:0 XAUTHORITY=/home/svision/.Xauthority flashplayer http://localhost/flash/sign.swf &
the result (when run in terminal) is: No protocol specified (flashplayer:15077): Gtk-WARNING **: cannot open display: :0
I would like to be able to have one local user connect to the X of another local user and run an X program. On fedora, I can simply run:
$ xhost +
And then have the other user run:
$ sol --display=0.0
This is not working on my ubuntu (10.10). I am guessing that there is an additional level of Xauth restrictions, but I cannot find out how to get past them. Both users are local to the machine. I would like to not use sux or gdsu as both require you to enter the password and I would like this to be seemless. I am aware of the security concerns and believe that I have mitigated them.
