Ubuntu :: 10.04 Laptop Can't Display Remote Xclock
Jul 27, 2010Hostname: Borg
OS: Lucid Lynx
Kernel: 2.6.32-24
Problem:
1. borg > xhost +
2. borg > ssh <anyuser>@<anyhost>
3. anyhost > export DISPLAY:<borg's IP>:0.0
4. xclock
NOTHING HAPPENS!!!! Any ideas? Here is what I have tried thus far.
Efforts:
1. gdmsetup - looked for security tab, doesn't exist
2. installed gdm2setup - still not there
3. looked for gdm.conf - not there
4. when doing ps -ef|grep X - there is a -nolisten tcp "could this be culprit" hmm not sure
5. modified /etc/ssh/ssh_config to Forward X
Ubuntu :: Lucid - Cannot Display Xclock On Remote Machine
Jul 23, 2010I'm having trouble displaying Xwindows programs on a remote machine. If I run "ssh -X newmachine" and I login and then run a program like xclock, I get the error message:
Error: Can't open display: localhost:10.0
If I run the same command to an anothermachine which is running Ubuntu 8.04 it works fine and xclock displays on my localmachine. If I run the command "echo $DISPLAY" on newmachine, I see:
localhost:10.0
Also, I have checked and xauth is installed on newmachine. What setting I have to change on Ubuntu 10.04 to allow remote display of Xwindows programs?
Software :: Xclock Running From Start Script Doesn't Display Correctly?
Feb 21, 2011I recently dist-upgraded from Debian 5 to 6 (squeeze). Since then, the xclock I run from my window manager's start script isn't displaying correctly (it displays only a "0"). The thing is, if I run the same command in my start script in my terminal, it works just fine, as it has always done...
I use this rather "old" X applications because I like my programs simple/not buggy/fast, and it's resulting a rather annoying problem (being that apparently nobody else has it...).
All other programs in my start script (gnome-terminal, emacs, xmodmap, etc) are working with no problems whatsoever.
My window manager: sawfish
Command to run xclock in my start script:
Code:
xclock -digital -brief -geometry -0+0
Attached picture:
Top: xclock initialized by start script
Bottom: xclock initialized by terminal
General :: X11 Forwarding - Error: Can't Open Display: <ip Of Display>
Jun 28, 2011I 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.
Fedora Servers :: Sendmail[31427]: Unable To Open Berkeley Db /etc/sasldb2: Unknown Error 13
Sep 7, 2010I've been using cyrus and sendmail together for a very very long time now. Just recently I upgraded to fedora 13 and now my virtual users can not send email from the /etc/sasldb2 passwords. I get in the /var/log/messages sendmail[31427]: unable to open Berkeley db /etc/sasldb2: Unknown error: Its weird that they can still log in and get email from imapd.conf
sasl_pwcheck_method:auxprop saslauthd
sasl_auxprop_plugin: sasldb
sasl_mech_list: LOGIN PLAIN CRAM-MD5 DIGEST-MD5
[code].....
I even tried re-creating sasldb2 and sasldblistusers2 shows my two users 'one' that is also a local user account and the saslauthd authenticates when sending emails, but the virtual user 'two' can't send just only can log in to receive. /etc/sysconfig/saslauthd is set up as mech=pam. but I don't see how that would be relevant to this issue.
CentOS 5 :: PHP Not Working - Blank Page - Get This Warning: Unknown: Failed To Open Stream : Permission Denied In Unknown On Line 0?
May 5, 2010I tried posting this before and I'm not sure what happened but I don't think it worked, so if it did please forgive the double post.am very very new to centOS and linux in general. I just want to setup a test web server that more closely mirrors our actual web server that is hosted by rackspace. I've installed centOS and tried to setup Apache, PHP and MySQL from a guide on the web using Yum. When I go to localhost in the web browser I'm able to see the default apache page. However when I create a php page it's just blank.When I look at the apache error logs I get this: PHP Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
I've been searching alot on the internet and I know the issue is permission related, but I don't know how to fix it. I've seen some forum posts that say you need to use the chmod 775 command on the /var/www/html folder.Currently when I do ls -l /var/www/html it returns
-rw------- 1 root root 19 May 5 13:16 index.php
-rw------- 1 root root 19 May 5 13:15 index.php~
I'm sure that this isn't correct but like I said I don't know much about how to set permissions or who the owner needs to be. I've done alot of searching and seen similar posts, but no one seems to explain it clearly.

Debian :: Error: Cannot Open Display: 0 When Trying To Launch Firefox
Sep 8, 2010So 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

Ubuntu :: Error - Cannot Open Display - 0 - When Opening Any GTK Application From The Terminal
May 13, 2011For 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.

After you supply root pw, nothing happens. If you launch it from a terminal, you see this:
