SUSE :: Error: Can't Open Display: Localhost:10.0
Apr 6, 2010
When I attempt to use Putty for xterm (to run DBCA for Oracle) I check x11 and put my IP Address in the Display field of putty. However, when I then try to execute ./dbca I receive the following:
Xlib: connection to "localhost:10.0" refused by server
Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
Error: Can't open display: localhost:10.0
I notice the following when logging in to the server as well.
Last login: Fri Mar 19 13:51:19 2010 from 10.47.48.33 /usr/X11R6/bin/xauth: error in locking authority file /home/oracle/.Xauthority. These are the same steps I take successfully on all the servers. The above file exists on the servers I can initiate the GUI, but not on <server1>.

I was trying to remotely log in to my desktop which uses 11.3 from my laptop via ssh. For some reason I get an empty field for the command echo $DISPLAY. and as a result an xclock command results in error: can't open display. I tried to set it to localhost:10.0 and I get: Error: Can't open display: localhost:10.0
I've tried :0.0 and I get: Invalid MIT-MAGIC-COOKIE-1 keyError: Can't open display: :0.0 ssh used to work about a week ago before I performed various security updates. I was wondering what' the solution to this. I checked the /etc/ssh/sshd_config file and ssh_config file both have X11 forwarding on. Can anyone with more experience out there give me any ideas?

I'm trying to connect to my linux server but I'm having some major problems. The server had OEL 5 installed and my local pc is running Windows XP. I'm using PuTTy to connect to the server with Xming running on my loacl machine. I login as root and run the following command - export DISPLAY={ipaddress}:0.0I then run xclock and get the following error - Xlib: connection to "{ipaddress}:0.0" refused by serverXlib: No protocol specifiedError: Can't open display: {ipaddress}:0.0The strange thing is that on my bosses pc (who has got almost the exact same setup ie. PuTTy & Xming) is works perfectly.

I'm SSH'ed in to my Ubuntu 11.04 machine and trying to take a screen shot of a virtual display where I'm running (hopefully) Firefox. I get the error
Code:
selenium@selenium:~$ xwd -display localhost:15.0 -out ~/desk.xwd -root
xwd: unable to open display 'localhost:15.0'
I know that I have displayed the right display variable because in an earlier script that runs at system bootup I have

I am trying to Install Open Suse 11.3 (burned as an ISO DVD) along with existing Win 2008 R2 OS. When I try to boot from the DVD it just logs in to Win2008 though boot from CD/DVD is enabled in the boot sequence. So i tried to mount the ISO and run from Windows ! BUT I get an error before installation starts telling that Win2008 R2 is not supported in open suse installer! Is there anything I can do to overcome this and install/retain both OS? In fact I am even trying to c hange my win2008 from R2 to Enterprise to see if I can overcome the problem!

I 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.

i just downloaded Nethack from [URl], and moved the extracted files to /usr/games. Then i changed the permissions in /usr/games/lib/nethackdir so i could access the lib files.
Nethacks runs in X, and it runs in terminal when im root. But for some strange reason it does not run in CLI when im not root, i get the message "Error: Can't open display:".

So I just installed 32-bit Squeeze. I've done exactly two things since booting into the first install: pt-get install gtk+2.0, and ./firefox, so unless gtk did something, this might be an easily fixable problem with Debian itself. After installing gtk and trying to run firefox via command line, it tells me
Code: Error: cannot open display: :0 I googled a bit and couldn't come up with a solid solution, but the problem seems to be around other places. Any idea how to fix this?

For awhile I have had this issue with the command line and every time I try to complete any command that requires GTK graphics, It always returns the error "Error: cannot open display: 0:" The "EXPORT display" command that I normally use to fix this issue is not working. The only issue that I can think might be the cause for this could be my upgrade to natty (which was in fact a clean installation), or when I edited plymouth so that the startup and shutdown animations would match my laptop's native resolution (by the way I would also appreciate it if I could do the same with the startup animation, only the shutdown really works). If anybody know how I could resolve this issue I would greatly appreciate it. Oh and for specifics on my machine, I am using an ASUS N82 with an NVIDIA GEFORCE GT335M graphics card, running Ubuntu 11.04.

I also had ever tried all methods they mentioned, but my problem is still there. I am using a MAC OS X 10.6 ssh a remote redhat server. I hope to see X of redhat on my own MAC. Below is what I've done: 'MAC_ip' stands for my mac; 'redhat_ip' stands for redhat server.
1) ssh to redhat server
2) change to root
3) type command: DISPLAY=MAC_ip:0.0
4) type command: export
5) Back to MAC
6) change to root
7) type command: xhost +Redhat_ip
8) vim /etc/ssh_config, add X11Forwarding yes
9) Back to redhat, type: xclock
I got below message: Error: Can't open display: MAC_ip:0.0 I also tried some methods to login as others suggested:

Made some network and hardware changes, and now I can't get the mailserver to work. It seems that sendmail can't loop to itself on 127.0.0.1. When I nmap localhost, I find that port 25 isn't open.
Naturally, nothing has changed on my system except for different routing, interfaces, etc.
So the question for sendmail gurus,is where should I be looking?
