When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only
export DISPLAY=localhost:0 && xclock
export DISPLAY=localhost:1 && xclock
export DISPLAY=localhost:2 && xclock

I am running hummingbird exceed on Workstation with an ip address of a.b.c.d, and connecting to a sun machine with IP address x.y.z.w running Solaris with XDMCP. From the sun machine, we commonly telnet to other sun and linux machines and run X applications.
We have just installed ubuntu 10.04, and I can telnet into that machine no problem.
However, running xterm on the ubuntu machine fails:
xterm Xt error: cannot open display a.b.c.d:0.0

I have downloaded java and installed it with chmod +x and then ./bin package.
Hereunder is an output from CLI (putty)
I understand that the system knows the java is in a wrong place but if I do java -version it finds it correctly. I don't know and I don't understand how do I need to tell the OS that the java is somewhere else, I just did that with export java home and java path but still dosen't work, it keep tells when I do whereis java "java: /usr/share/java"
Here is another output:

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've been running Ubuntu (10.10 - 32 bit) for about 3 months. Being curious about the very basics of Java programming I've just installed Netbeans 6.9 through the Ubuntu software centre and done the "Hello World" exercise within Netbeans. The file is in my Home folder but I'm not clear how now to try and run it.
Some Googling has raised some contradictory recommendations about adding the Sun/Oracle repository and the installing JDK6 as well. I'm now getting out of my depth so if someone can share knowledge on where to go from here I would be grateful. Have just registered so I hope this post is expressed correctly.

First of all I'm using Ubuntu 9.10.I have tried using System/Preferences/StartupApplicationsI added:java -Xint -cp /home/Edgar/dist/Edagr.jar:/home/Edgar/dist/Annotator.jar com.ionetrics.edgar.EdgarI don't know if I am calling this incorrectly or not. I know that I can call this from a terminal and it will run correctly.However it will not run at startup. I have added Teamviewer to startup and it runs properly.

I have a bash script that calls a java class method. The method returns a string to the linux console when run independently. how can I assign the value from the java method to a variable in a bash script?running the script: java -cp /opt/my_dir/class.method [parameter]
output: my_string if added in a bash script:
read parameter
java -cp /opt/my_dir/class.method [parameter] | read the_output
echo $the_output
the above doesnt work, I also tried unsuccessfully:
the_output=java -cp /opt/my_dir/class.method [parameter]
the_output=`java -cp /opt/my_dir/class.method [parameter]`
java -cp /opt/my_dir/class.method [parameter] 2>&1
How can i get the output stored into the_output variable?

i have added a tomcat startup service using chkconfig. I have set up JAVA_HOME and JRE_HOME as well ass alternatives to point to the correct location.I have an init script in /etc/init.d. When i start the tomcat service using [ /etc/init.d/<x> start ] everything works fine and the environment variables for JAVA_HOME and JRE_HOME are used correctly.Now i added the service <x> using chkconfig --add so that it can start on boot up. But now the service does not use the system environment variable for JAVA and JRE setup by me.Also after complete bootup if i try to start the service using [ service <x> start] the environment variable in the shell are not used. don't want to exclusively declare variables for JAVA_HOME and JRE_HOME in the init script.

I'm having a strange issue with the PATH variable when running the command 'sudo su'. When executing this command the PATH variable changes. No problems there, but it changes to:
Code:
Looking at this, there are two weird entries (//sbin and //bin) which should both start '/usr' instead. I'm not sure how I've managed to change this, or how a piece of software I'm using has done it (more likely it was me I expect), but could anyone suggest which file to look in to correct it? If it makes a difference the machine is running CentOS 5.

Code: ~ $ /usr/java/jre1.6.0_25/bin/java -showversion Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object
That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.

I am a newbie to Linux. I tried setting environment variable using export JAVA_HOME=/usr/java/jdk1.6 but that was not permanent (i.e is was there for that terminal session). I want to know how can i set environment variable permanently in Fedora 13 just like we do in windows.After google search, some user suggested to edit bashrc and profile file for setting environment variables but above file contains some shell programs.

I'm trying to define a variable, CHAN, by dividing another variable, FREQ, by a number. FREQ is a value from a file (called header.txt). What I think I'm doing with this bit of code is reading a number from header.txt whose location is specified by the head and tails, assigning it to FREQ and then defining CHAN with bc.
Code:
#!/bin/bash
while read FREQ

I am connected to work via a VPN. I am logging into a Solaris box at work from OpenSuse 11, using ssh -X. I would like to start a GUI on the solaris box. The problem is that I don't know what value to give the DISPLAY variable. Is it the local internal LAN ip address, for my machine? I did try that, and I tested it using, xterm on the solaris machine. It says it can't open the display. I have enabled remote connections on my machine using xhost +.I have to run a performance test on the Solaris box at 7am in the morning... so need to find out how to start the GUI

I have a problem to use echo to display the content of a variable.
This is what I do:
Code:
#!/bin/bash
USAGE="Usage: name [OPTIONS] [DIRECTORIES]"
echo $USAGE
When I run this little script I get the following output:
Usage: name [OPTIONS] R
So I think that [DI might be some sort of escape sequence. But I do not know how to unescape it. Does anyone have a hint for me?

I have created a shell script to customise mv command, now i have achieved to accomplish all the functionality of mv by using alias. But i found difficulty in accomplish the funcionality with options [Like mv -i or mv -f etc.]. I thought about logic which check the first argument whether its starting with a minus [-] or not. if its starting with argument it will set a flag and execute accordingly. But whenever this condition is checked it shell script will throw error of destination operand missing. But the same will work with out option.
Note: I have used an minus[-] expression for decreasing a counter on the script above. The below mentioned is the portion of script. Sry for troubling Im not gud @scripting.
for i in $*
do
{
argument=`expr $argument - 1`
if [ $argument = 0 ];
then
exit

I have fresh installation of Ubuntu server upgraded with apt-get dist-upgrade and with XFCE4 installed on my notebook. The problem is whenever I type startxfc, startx or X, the NTB freezes, CRT display connected to docking station/port replicator turns off, LCD in NTB gets black. The system does not respong to any signal, even the alt+sysrq ones. If I even install Xubuntu-desktop, as the X gets loaded every start, system everytime hangs after few seconds and I cannot do anything. Now I reinstalled and tried autoconfiguration with Xorg -configure. If I start the X with this configuration file, the result is still the same. Log at /var/log/X11/ seems to be blank.
Any ideas? Should i try to get drivers for my video card? I thought this is not necessary, the X server should start without anything, even only with basic resolution settings. As I looked, the video card chipset (Intel 82852/82855) is detected in my /root/xorg.conf.new file.

I'm using Fedora9. I cannot start wireshark or tcpdump because of the lib dependency error:
Code:
[root@localhost ~]# wireshark
wireshark: error while loading shared libraries: libpcap.so.0.9: cannot open shared object file: No such file or directory
I updated libpcap before and the latest version is libpcap.so.1.1. I changed the version because of another application but I cannot remember when I did it, perhaps on Sep.11?
Code:
[root@localhost lib]# ll |grep libpcap
-rw-r--r-- 1 root root 309670 2010-09-11 08:10 libpcap.a
lrwxrwxrwx 1 root root 12 2010-09-11 08:10 libpcap.so -> libpcap.so.1
lrwxrwxrwx 1 root root 14 2010-09-11 08:10 libpcap.so.1 -> libpcap.so.1.1
-rwxr-xr-x 1 root root 243207 2010-09-11 08:10 libpcap.so.1.1
So I tried
Code:
ln -s libpcap.so.1.1 libpcap.so.0.9
but it doesn't work.

How would i write a script to display permission on each folders in $PATH variable below format.
